A T S 006181 R e v C 8/20AZA404Multi-Channel Network AmplifierApplicationsAZA Series amplifiers integrate with Atmosphere signal processors which makes them ideal for use in restaurants, presentation rooms,classrooms, conference rooms, and retail background / foreground music applications.General DescriptionThe AtlasIED Atmosphere AZA404 four-channel amplifier is designed to interface with the Atmosphere family of products, such as the AZM series of processors. The AZA amplifiers can be configured in three different configurations to meet the design requirements of any installation. These AZA models are factory preconfigured in a four-channel, 70V mode. If the design requires four channels of low impedance amplification, the AZA amplifiers can be configured as four-channel models with either 4Ω or 8Ω load impedances. Many system designs require both low and high impedance amplification. These AZA models can be configured to deliver 70V / 100V for apaging / background system on two (2) channels plus two (2) additional 4Ω or 8Ω amplifier channels for foreground stereo application.These AZA models come standard with four (4) balanced line inputs and an accessory slot for an optional four-channel Dante™ receiver card (model DPA-DAC4), giving the AZA404 and AZA804 a total of up to eight (8) inputs. All inputs can be mixed and routed to any of the four amplifier channels. All four (4) amplifier channels have an assortment of advanced DSP tools.The AZA404 is ready to use out of the box in four-channel, 70V mode, with no configuration or network connectivity required, making them easily paired for use with AtlasIED Atmosphere Signal Processors.Features• 4 Amplified Channels• AZA404 Configuration Power Levels • 4 x 100-Watt 70V (Factory Default) • 4 x 100-Watt 100V • 4 x 75-Watt @ 8Ω • 4 x 50-Watt @ 4Ω• 2 x 100-Watt 70V/100V & 2 x 75-Watt @ 8Ω • 2 x 100-Watt 70V/100V & 2 x 75 -Watt @ 4Ω• Integrates with Atmosphere AZM Zone Master • Energy Efficient• Convection Cool / Fan Assist • Accepts Low Z & Hi Z Loads• Onboard Web UI for Remote Monitoring of Status & Levels • Front Panel Power Switch Disable• APD - Auto Power Down with Audio Sense Turn On •Dante™ Optional Accessory Card SlotS o u n d L P .

Nexus 4就得这么玩 谷歌四儿子体验MIUI
自从谷歌四儿子Nexus 4（以下简称：N4）问世以来，其在全球范围内的受欢迎程度绝对不亚于iphone。
硕大的屏显、主流的配置、唯美的做工、无暇的手感加上官方公布的低廉价格，使得该手机在发布初期经常卖断货。
与此同时，在国内，所有商家都本着优良的“加价不加量”的光荣传统，使得N4的价格一直居高不下，一时间成为了不差钱人士的首选，这也让许多囊中羞涩的买家望而却步。
时过境迁，现在N4的价格已经趋于稳定，非常亲民了，同时也引来了更多消费者的关注。
但是我们不得不承认，搭载着原生Android系统的N4在上手起来非常的不便，同时也缺乏了许多必要的实用功能。
如此一来，对于刚刚接触Android系统的用户就显得更加的麻烦了。
这个时候我们何不尝试去刷入一个最适合中国人使用习惯的ROM呢？不用多说，大家已经猜到了，这便是今天笔者要谈到的话题——Nexus 4体验MIUI。
锁屏与下拉通知栏首先笔者要声明的一点就是，本次在N4中刷入的MIUI并非小米公司官方制作的，而是来自民间高手的移植作品。
熟悉MIUI的朋友肯定都知道，该系统的默认锁屏样式是以一个圆点为中心，用户手指点按之后会在上下左右四个方向显示4个功能，划到哪个位置就可以开启对应的功能。
同时，如果双击这个圆点的话，就可以激活音乐模式。
Nexus 4的MIUI系统截图细心的读者肯定都会发现，在锁屏状态下的屏幕左下角有一个类似于菜单键的虚拟按键。
的确，那个就是菜单键，但按上以后没有任何的作用，笔者相信这是一个BUG所在。
虽然在视觉方面有些欠妥，但是绝不影响正常使用的。
其实这也有个“好处”，那就是让我们更容易分辨出这不是一款出自官方的ROM了。
Nexus 4的MIUI系统截图在下拉通知栏方面，我们能够看到MIUI V5那浓郁的气息，简洁模式与单页模式的显示样式可以根据用户自己的喜好自由的切换。
只不过，笔者还是建议大家选择简洁模式，毕竟有很多功能选项只要一次性设置完之后就不用再二次设定了。
兰尼电子GS412L Bass电钢琴电铃器说明书
42 11 42 1L A N E Y A M P L I F I C A T I O Nw w w.l a n e y.c o.u kGS412LAGS412LSLaneyDear Player,Thank you very much for purchasing your new Laney product and becoming part of the worldwide Laney family. Each and every Laney unit is designed and built with the utmost attention to care and detail, so I trust yours will give you many years of enjoyment.Laney products have a heritage which stretches back to 1967 when I first began building valve amplifiers in my parent’s garage. Since then we have moved on from strength to strength developing an extensive range of guitar, bass, public address and keyboard amplification products along with a list of Laney endorsees that includes some of the world’s most famous and respected musicians. At the same time we believe we have not lost sight of the reason Laney was founded in the first place - a dedication to building great sounding amplification for working musicians. Warm Regards,Lyndon Laney CEOPage 2/4412 412INTRODUCTIONThe GS412LA & GS412LS are a pair 4 x 12” cabinets optimised for use with GH100TI - to enhance the amplifiers huge tonal range and produce stunning tone at any volume, but are equally at home with any other amplifier from the Laney range.Rated at 320 watts (16 ohms) these cabinets can be used in isolation or together to form an 8 x 12 stack. Construction features a robust plywood cabinet, with black powdercoated steel side bar handles and corner protection, castor cups on top of the straight cabinet to allow stacking, removable kick proof grille and a set of roadworthy casters mounted to each model for ease of mobility.Every Laney product is extensively play tested by experienced guitarists to ensure it has the tone and durability to perform at the very highest level, before being shipped to our customers.We hope you enjoy using your new extension cabinet as much as we enjoyed designing and making it. It should give you years of trouble-free service, however please take time to read this manual, as it will allow you to get the best from your GS412LA or GS412LS.Best wishes from all at Laney.LaneyCHECK CONTENTS ARE ALL INCLUDED16 Ohms16 OhmsDesigned in the UK by Laney1. Open top of carton, remove top foam tray and open protective bag, pull back to sides.2. Flip carton over. Cabinet rests on its castors.3. Remove the Carton, bottom foam tray and protective bag.4. Enjoy.UNPACKING INSTRUCTIONSAlways use good quality speaker cablesThis product conforms to the requirements of the following European Regulations, Directives & Rules:-CE Mark (93/68/EEC), LowIn order to reduce environmental damage, at the end of its useful life, this product must not be disposed of along with normal household waste to landfill sites. It must be taken to an approved recycling centre according to the recommendations of the WEEE(Waste Electrical and Electronic Equipment) directive applicable in your country.IMPORTANT SAFETY INSTRUCTIONSDuration Per Day In Hours 864321 ½1½¼ or less Sound Level dBA, slow response 909295971001021051101151). Read & Retain these Instructions carefully before installing or operating this product.2). Comply with Warnings: All warnings and instructions for these products should be adhered to.3). Unpacking: On unpacking your product please check carefully for any signs of damage that may have occured whilst in transit from the Laney factory to your dealer.

We strongly advise you to keep your original transit carton, since in the unlikly event that your unit should develop a fault, you will be able to return it to you dealer for rectification securely packed.4). Amplifier Connection: In order to avoid damage , it is advisable to establish and follow a pattern for turning on and off your system. With all system parts connected, turn on source equipment, tape decks, cd players, mixers, effects processors etc, BEFORE turing on your guitar amplifier. Many products have large transient surges at turn on and off which can cause damage to your speakers.By turning on your guitar amplifier LAST and making sure its level control is set to a minimum, any transients from other equipment should not reach your loud speakers. Wait till all system parts have stabillised, usually a couple of seconds. Similarly when turning off your system always turn down the level controls on your guitar amplifier and then turn off its power before turning off other equipment5). Cables: Never use shielded or microphone cable for any speaker connections as this will not be stubstantial enough to handle the amplifier load and could cause damage to your complete system.6). Caution: These professional loudspeaker systems are capable of generating very high sound pressure levels. Use care with placement and operation to avoid excessive levels that can cause permament hearing damage.7). Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in susceptibility to noise induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time.The U.S. Government's Occupational Safety and Health Administration (OSHA) hasspecified the permissible noise level exposure in the chart oposite.According to OSHA, any exposure in excess of the above permissible limits could result insome hearing loss. Ear plugs or protectors in the ear canals or over the ears must beworn when operating this amplification system in order to prevent a permanent hearingloss if exposure exceeds the limits set forth oposite. T o ensure against potentiallydangerous exposure to high sound pressure levels it is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation.8). Servicing: The user should not attempt to service these products. Refer all servicing to qualified service personnel。

NeXus: Event-Related potentialsEvoked potentialsfor Psychophysiology & NeuroscienceT his NeXus white paper has been created to educate and inform the reader about the Event Related Potentials (ERP) and Evoked Potential (EP) functionality offered by the NeXus Instruments with the BioTrace+ software version 2009a and later.The NeXus-10, NeXus-16 and NeXus-32 members of the NeXus family of physiological monitoring and feedback instruments are multi-modal systems that support a wide range of sensors and applications, including ERP/EP and Biofeedback/Neurofeedback functions. BioTrace+ runs on Windows (XP/Vista ™) based PC’s. The NeXus family of products has medical class IIa certification (EU) and is FDA (US) registered. Exclusive world wide distribution by Mind Media BV:#1 in Europe for multi-modal, multi-channelphysiological monitoring & feedback.The picture above shows a BioTrace+ VEP screen design on a PC with dual monitors and the wireless NeXus-10. This is a 10 channel physiological monitoring and feedback platform that includes a trigger input, for high precision event/stimulus synchronization.Please note: since the NeXus-4 does NOT have a trigger input, it can not be used for ERP or EP applications. NeXus-10, 16 and 32 all have trigger inputs and support EP/ERP.~ Table of contents ~What are Event-related Potentials?

Each time the subject recognizes an event, a specific response is required, like pressing a button.An example of this is the classical oddball paradigm:A tone (1000 Hz) is repeatedly presented (the non-target) at intervals of 1-2 secondswhile at random a higher tone (for instance 2000 Hz) is presented instead. (the target) Each time the non-target is presented, the subject should press a button, but when the target is presented, the subject should refrain from pressing this button. Alternatively, the subject could also count the times the target tone is presented and skip the non-targets, rather than pressing a button.By averaging the time-locked EEG signals at each event (a tone in this case), the ERP will become visible through potentials (waveforms) that have a certain latency (time in ms from stimulus onset) and a positive or negative amplitude, expressed in microvolts pk-pk.In the example above taken from the BioTrace+ software on a NeXus-10, we can see the negative N100 component (at around 100 ms from stimulus onset) and the positive P300 component at around 350 ms, with an amplitude of 11 µV. This signal was measured on Cz with a linked ear reference. The green curve is the averaged response of the target stimuli, (100 averages) the red curve is the averaged response of the non-target stimuli. (250) Note: the target stimulus is also called the GO event, and the non-target event is also called the NOGO event. The target is also sometimes called the ‘frequent’ stimulus and the non-target the ‘rare’ stimulus. For ERPs the word ‘event’ and ‘stimulus’ mean the same.ERP Applications for researchAnalysis of the amount of response errors, reaction time and in particular, the latency and amplitudes of the ERP components, can provide important information about:a)how the human brain processes information (cognition)b)variables of attention.So while evoked potentials simply reflect the processing of the physical stimulus (the exogenous potentials) the event related potentials are caused by ‘higher’ processes that are thought to involve memory, expectation (Bereitschaftspotential) and attention. They are also called endogenous potentials.Thousands of ERP studies have been published up to date, for a wide range of applications. Some examples are listed below, in no particular order.a)Attention problemsb)Substance abusec)Visual emotion processingd)Schizophreniae)Alzheimerf)Sleep researchg)Recognition memoryh)Memory and language processingi)PTSDj)Mild traumatic brain injuryk)Learning disabilitiesl)Autismand so on….On the website of the U.S. National Library of Medicine and the National Institutes of Health you can search for an overview of published studies that involve ERP or P300 experiments.ERP: Electrode locationsThe ERP is typically acquired by placing the positive electrodes on the scalp according to the 10-20 EEG system while the negative electrodes are placed on the ear-lobes or mastoids as reference. (linked ear reference). Sometimes an average ear reference is used.In principle ERP’s are obtained with uni-polar (mono-polar) placements.The ground electrode can be placed anywhere, but typical locations are: in the neck (cervical 7), on the nasion, or a free location on the head. The ERP can typically most clearly be observed on the central positions of the head. Some examples of electrode placements:a)Single channel placement: positive electrode 1 on Cz, reference on left ear, theground electrode on the right ear.b)Dual channel placement with EOG artifact correction: positive electrode 1 on Czand positive electrode 2 above the left eye (VEOG). Negative electrode 1 on leftear lobe, negative electrode 2 below the left eye. Ground on the neck. (cervical 7)c)Dual channel placement: positive electrode 1 on Cz, positive electrode 2 on Fz(or Pz), reference electrodes on linked ear. Ground on the neck.d) 4 channel placement: positive electrodes 1, 2 and 3 on Fz, Cz and Pz. Linked earreference. Electrode 4 can be used for EOC artifact rejection or Fpz or Oz.e)19 channel placement: all EEG channels (NeXus-32) are placed using thecomplete 10-20 system with channels 20 and 21 on A1 and A2 for linked ear oraverage ear reference.f)64 channel placement: for ERP studies that involve source localization,minimally 19 but preferably 64 channels are used with ear reference.ERP: EEG settings for data acquisitionBecause the typical ERP contains long latency components (low frequency) such as the P300, the high pass filter settings should be set quite low. We advise a 0.1 Hz setting. When using higher settings, the P300 waveform may become suppressed and difficult to locate. The low pass filter can be set to 30 Hz (typical) or higher. We do not recommend using a DC-EEG signal without high pass filters, as DC-EEG may contain electrode drift. We advise to always use silver-silver/chloride electrodes or sintered electrodes which have minimum drift.Filter setting: use 0.1 Hz to 40 Hz as the standard filter settings. FIR filters are better for offline analysis as they cause no phase distortion. The standard IIR filters however can be used for both the online and offline data acquisition.Time window: use a time window of at least 500 milliseconds, so the P300 can be observed Samplerate: use a samplerate of minimally 256 SPS up to 1024 SPS if 1 millisecond precision is required.ERP: Design of P300 experimentsThere exist many guidelines for doing ERP experiments, published by different authors. Here are a few basic hints and tips that we provide for general P300 experiments:a)Keep the experiment (task) simple and avoid ambiguitiesb)Focus on a specific component (like the P300)c)Use a fairly high ratio of NOGO events to GO events. (3:1 or more) **d)Minimize artifacts like eye blinking, swallowing, EMG, movement as in every EEGmeasurement.e)Use a randomized design. (randomized time between events, randomized occurrenceof GO and NOGO events). BioTrace+ offers this functionality.f)When only using 1 or 2 channels: place them on the central positions (Cz,Fz,Pz)g)Study some recent literature regarding ERP’s and experiment design. ***** The more ‘rare’ the GO event (target) is, the more pronounced a component like the P300 is. However this also means that more NOGO events need to be presented and the ERP experiment will last longer. In order to get a good averaged response for the P300, we advise to get at least 100 artifact free GO (target) events. With a ratio of 3:1 this means that there would be 300 NOGO events. Some studies use ratios that are even higher. (4:1 to 6:1)*** For a short list of recommended literature, please refer to the last pages of this document.What are Evoked Potentials?Evoked potentials (EP’s) are physiological responses in the EEG which are time locked to an ‘stimulus’ that is repeatedly (100+ times) presented to a human subject. Contrary to ERP’s no response or cognitive processing by the subject is required. The goal is to simply analyze the way the brain handles visual, auditory or somato-sensory input. (stimuli)As of version 2009, BioTrace+ supports visual evoked potential (VEP) with checkerboard patterns on a computer monitor, for VEP research purposes.VEP: the visual evoked potentialThe VEP is triggered by repeated sensory stimulation of a subject’s visual field and can be made visible by averaging the time locked EEG. The visual stimulation can take place by:a)Checkerboard pattern reversalb)Flashing black/white imagec)Pattern onset stimulusd)Photic Stimulation (light)The current BioTrace+ version (2009) supports methods a & b. According to the “Visual Evoked Potentials Standard 2004” (by Vernon Odom et al), pattern reversal is the preferred technique for most clinical purposes.A sample pattern reversal VEP is shown below, with the N75, P100 and N135 components marked. (positive is UP)Please note that the P100 peak latency is not only defined by physiological factors, but also by pattern size, pattern contrast, mean luminance, poor fixation and miosis. Please refer to the document by Vernon Odom et Al (2004) for more details.VEP Applications for researchAnalysis of the averaged response of the VEP can provide information for research applications like: (in no particular order)a)Photosensitivity and Epilepsyb)Cortical Visual Processingc)Cortical Blindnessd)Optic Neuritise)Multiple SclerosisVEP: Electrode locationsThe VEP is typically acquired by using bi-polar placement according to the 10-20 system, when 1-4 channels are used. The simplest placement is a single channel bi-polar montage with the positive electrode on Fz and the negative electrode on Oz. The ground electrode can be placed on an earlobe, a mastoid, the forehead or a location like Cz.For 19 channel recording a referential placement can be used, so that the results can be mapped. (topographically)VEP: EEG settings for data acquisitionFilter setting: use 1 Hz to 100 Hz as the standard filter settings for offline analysis. FIR filters are recommended for offline analysis as they cause no phase distortion. The standard IIR filters can be used for the online data acquisition. (set at 1-40Hz)Time window: use a time window of at least 300 milliseconds, so the P100 is clearly visible. Samplerate: use a samplerate of 512 or 1024 samples per second.Other evoked potentials: BAEP and SEPOther evoked potential applications like brainstem auditory evoked potentials and somatosensory evoked potentials are not supported by BioTrace+ at this time. Since they require either high samplerates above 10,000 samples/sec (BAEP) or electrical stimulators (SEP) no implementation is planned at this moment.NeXus: solving the problem of EEG & event synchronizationIn order to get high time-resolution on the averaged responses, the presented stimuli (events) must be synchronized very precisely with the EEG signals. Most ERP/EP equipment based on older technology suffers from unknown or varying latencies (delays) between the time that the stimulus is presented and the time it is recorded. This causes the following problems:a)Delay: the factual latencies of ERP/EP components are shifted in time and can be offby several milliseconds. (errors could be in the order of 5-10 ms or worse)b)Jitter: because of timing errors, the time between stimulus presentation and therecording of the event is unstable. This causes absolute shifts in ERP/EP components time as well as smoothing-out of the ERP/EP components.Solution: the NeXus series of equipment solves this problem by measuring the exact time the actual stimulus (event) was presented and feeds it back into the digital trigger input of the NeXus through a special interface. The NeXus trigger input is monitored with the same timing and time resolution as the actual EEG and therefore the EEG and the stimuli are recorded with the same precision and timing.This means that when the BioTrace+ Software generates (presents) a stimulus, there is no need to worry about any delays the Windows Operating System (© Microsoft) may introduce, as the hardware of the NeXus aqcuires and buffers the EEG signals and the TRIGGER input at the exact same time: in other words, within 1 data sample. This is so even if it takes some time for the data to travel from the NeXus to the PC by BlueTooth, USB or fiber optic.An example for the presentation of AUDIO stimuli is shown below:As you can see in this picture, the audio tone is generated by the BioTrace+ software, then measured by the NeXus Trigger Interface and immediately fed back into the trigger input, while NeXus and BioTrace+ acquire the EEG signals. The same principle applies to light signals (computer images), as these can be measured with a light-sensor. NeXus-16 and NeXus-32 also have a trigger input, which is located on the front.NeXus: the digital trigger inputThe NeXus-10 and other NeXus systems with trigger inputs are able to acquire physiological signals, like the EEG, at high speed (256 to 2048 samples/sec) while simulateously acquiring events or stimuli through the trigger input.On the NeXus-16A, NeXus-16B and the NeXus-32 series, the trigger input is located on the front (see the red arrows in the pictures below) whereas on the NeXus-10 the trigger input is found at the back and coincides with the digital SpO2 (Oximetry) input. The only limitation of this is that on the NeXus-10 SpO2 can not be used during ERP/EP data acquisition.Note: all NeXus systems with a trigger input support ERP/EP. The only difference is the number of channels and the connector used for the trigger input. The NeXus-4 does not have a trigger input and therefore does not support ERP or EP applications.BioTrace+ for NeXus: event presentation modesThere are basically two modes of presenting stimuli (events) and recording the ERP and EP with NeXus and the BioTrace+ software:A)using the BioTrace+ built-in presentation builder and generatorB)using a third party (external) event presentation software such as E-Prime (®Psychology Software Tools Inc. ) or Presention (®Neurobehavioral Systems. )Mode A: for quick and easy creation of ERP and EP experiments, we advise everyone to use the BioTrace+ built-in presentation builder and generator. For most ‘standard’ experiments involving sound or images this is the best option. BioTrace+ enables you to build your own list of stimuli (events) and use your own digital audio or images files, or the preset files of BioTrace+ to generate experiments with a few mouse clicks.Advantages:-Quick and easy building and editing of eventlists-Export and Import events lists created by others-Works for several ‘standard’ ERP and VEP applications-Randomization of events, timing and sequences-You can use your own sound and images files-Requires just one computer.-Very high precision (time resolution) through the NeXus trigger interface.Cons:-Complicated experiments may not be possible-Limited event editing options.Mode B: when the BioTrace+ presentation builder does not suffice, or you already have created standard experiments with external stimulus presentation software, the other available option is to use that software and send the events through a serial communication cable (RS232) to the computer that is running BioTrace+.Advantages:-Virtual unlimited freedom in creating event scripts-The ability to use ‘standard’ scripts created by others-Use your own sound and images filesCons:-Potentially time intensive programming and script creation-Requires 2 computers and serial cable link-Potential delays and unknown latencies by serial communication of events between the 2 computers. (the delays are unknown, but could be as large as 5-10 ms)Note: please note that both modes (A and B) require additional external hardware. Mode A requires the NeXus Trigger Interface and Mode B requires a special RS232 connector cable that also outputs a signal to the trigger input of the NeXus.The NeXus Trigger InterfaceIn order to get the high precision on the EEG and stimulus synchronization you will always need the NeXus Trigger Interface. Currently this is available in the Mark I version, which has the following inputs and outputs:a)Audio input: for a standard audio (mono) jackplugs based cable that connects to theaudio output of your soundcardb)Microphone input: this connects to a mono microphone (included) which can recordsounds from the environment for event synchronizationc)Light-sensor input: this sensor measures the transition of dark to light on a computerscreen which can be used to synchronize the presentation of images on a LCDcomputer screen.d)Trigger Output: this cable connects to the trigger input of your NeXus-10 or NeXus-16/32.How does this interface work?When the BioTrace+ software is running and acquiring EEG (and other) signals, it is also continuously scanning the trigger input. When the software is simultaneously running a presentation (list of stimuli/events) and generates an audio event or presents an image, the Trigger Interface will measure when the audio tone is played and create an event marker in the EEG that marks this very event.After the session is over and all events (stimuli) have been presented, you will run an offline analysis in the BioTrace+ software which knows exactly WHICH events it has presented, and WHEN, because it fed them back in the trigger input.Does the Trigger Interface introduce any delay?The answer is simple: in principle it does not introduce any delays. This interface is entirely based on a hardware solution which will send a trigger to the NeXus once the AUDIO tone or LIGHT stimulus has been detected.AUDIO:For AUDIO it does depend on the audio wave files you use though. Please always use wave files that have a very short ‘attack’ so the sound is at full volume almost immediately. (within 2 ms) You also want to put the speakers close to the subject. Sound travels at about 343 meters per second and a distance of 1 meter would therefore already introduce a 3 ms delay! We do not advise to use headphones, as these may induce 50/60Hz interference onto the EEG. Putting the speakers within 30 cm of the subject’s ears (or closer) would be optimum. IMAGES:For the LIGHT stimulus, we may assume that for a LCD monitor all pixels are lit up at the same time and the eye and light sensor detect the IMAGE changes at the same time.In both cases it should be possible to reach up to 1 ms precision in event synchronization. Please note: the NeXus Trigger Interface has been developed for research applications only and is not a medical device.BioTrace+: the event presentation builderThe BioTrace+ event presentation builder works in several steps:1)Step 1: choose the type of presentation and it’s type of paradigm, type of stimulus anddata folder where the event files are located2)Step 2: choose the parameters of the event timing, the randomization, type of requiredkey presses etc…3)Step 3: generate the list of events and edit the list of events manually if required.4)Step 4: save the presentation file you just created.Example1: an example for a P300 experimentIn the example below, the STEP1 parameters for an ERP Oddball Paradigm are shown:In the type of presentation, you may choose from:A)ERP presentationB)VEP presentationIn the type of paradigm you may choose from:A)ERP: Single stimulus (1 GO event only)B)ERP: Oddball paradigm (GO and NOGO events)C)ERP: CNV Oddball with fixed warntoneD)ERP: CNV Oddball with variable warntoneA)VEP: checkerboard pattern reversalB)VEP: monitor flash stimulusC) VEP: plug-in DLL photic stimulation (Optional: only available as add-on!)In the type of Stimulus you may choose from:A) Visual stimulusB)Audio stimulusC)Plug-in DLL for external stimulation (Optional: only available as add-on!)In the example below, an example is shown for STEP2. In this dialog box the parameters of the event timing and sequence can be set:a)In the time between events you enter how time there is between each next event. (here shownas minimally1000 ms and maximally 2000 ms)b)When the checkbox (Randomize time between events) is set, the computer will choose anytime between MIN and MAX that you previously entered.c)Below the list of GO and NOGO event you can enter the required KEY presses for each GOor NOGO event.d)In the Amount fields, you enter how many GO and NOGO events should be generated. Hereshown in the ratio 4:1 of NOGO to GO.e)The GO-NOGO randomization selects how much the computer will randomize the sequenceof the events. You can manually edit this sequence in the list editor that opens after you click the “Next >>” button, which will build the list of events.When you press “Next >>” the following box will appear. Press OK to continue:After that the Event Presentation Editor will be displayed on the computer monitor.Example2: an example for a VEP experimentIn the example below, the STEP1 parameters for a VEP experiment are shown:In the example below, the STEP2 parameters for a VEP experiment are shown:In this dialog box you can set the pattern reversal stimulus frequency, amount of stimuli, the duration and the image file you want to use. When you press “Next >>” a dialog box will appear for confirmation.Then press OK to continue and open the Event Presentation Editor which will display the generated list of stimuli.BioTrace+: the event presentation editorThe BioTrace+ event presentation editor is where you view the entire list of events (stimuli) that BioTrace+ generated for you, using the parameters you entered.You can click on events and preview them. With the buttons “Move Up”, “Move Down” and “Remove Event” you can move single events up, down or remove them from the list.With the check box stating “Remove but keep time” you can select whether you want to create a “Gap” when you remove an event, or keep the time sequence in place. (this option is shown selected in the example below)When you press the “Start Test” button, the event list will start to play and present you the entire list of events in preview mode.The LOAD and SAVE buttons can be used to load or save event presentation files. These are by default stored in the \BioTrace\Presentations folder.If you want to ENABLE the list of events currently in memory (loaded) and RUN the presentation at the next time you record a session, please set a check, in the checkbox shown at the left button side.If you do not set this check, you may have a presentation loaded into memory, but when you record a new EEG session, it will not be presented.Press the “OK” button to close this dialog box.BioTrace+: running an ERP/EP presentationRunning an ERP or EP presentation, is as simple as building or loading a presentation file……then enable the “Run this presentation…” option in the Event Presentation Editor:After this you load a feedback screen as usual. (for instance an EEG Master screen) and start a recording as usual. Just before starting the actual recording, the BioTrace+ software will ask you to confirm if you really want to run this presentation. Press OK to run the presentation or press CANCEL to start the session without running the presentation.Please note: when you run a presentation that includes IMAGES, BioTrace+ will try to display these images on the secondary monitor, so you can use the primary monitor for the signal validation. If no secondary monitor and display screen is present, the primary monitor will be used instead! In that case, please load an empty screen, without virtual instruments.BioTrace+: ERP/EP Averaged Response AnalysisWhen the ERP or EP presentation has finished (and the session has been stopped) you can choose the “Averaged Response Analysis” option from the main menu, or from the overview screen. (right click, under Analysis Options)In the next Dialog Box you should select which EEG channels you want to use for the averaged response. The example below illustrates the two default channels, used on the NeXus-10.Following this selection, you enter the ERP Analysis Dialog box.In the ERP Analysis dialog box you select the following options:1)The single data channel you want to display. (say EEG1)2)The two ERP conditions you want to compare. (say NOGO and GO)3)The ERP conditions you want to overlap for all selected channels.4)The markers you want to add and display in the ERP graphsThe example below display the averaged response for the EEG1 raw data channel for 100 GO events (green graph) and 250 NOGO events. (red graph) recorded on a NeXus-10When you press the “Compute/Refresh ERP Graphs” button, the software will recomputed the ERP graphs using the conditions you selected.When you press “Save ERP: ASCII file” the BioTrace+ software will save the ERP graphs in an ASCII format that can be imported into third party software.An example of a 21 channel ERP with NeXus-32:The example below display the averaged response for the EEG1 raw data channel for 100 GO events (green graph) and 400 NOGO events. (red graph) recorded on a NeXus-32.The graphs on the right displays the all overlapped graphs (data channels) for condition 1, which are the NOGO events. Recording ERP or EP on the NeXus-32 is very similar to the NeXus-10. However the NeXus-32 will use 19 EEG channels (plus 2 for the linked ear reference) for the digital EEG, and therefore you will need to select these 19 channels before you do the ERP Analysis. An example is shown below (selection of channels 34 to 52)。
Rane MH 4 手机头戴式控制台操作指南说明书
Manual-1OPERA TORS MANUALMH 4HEADPHONE CONSOLEQUICK STARTConect the output from any stereo source such as a mixer or tape deck, and plug the left and right inputs into therespective INPUT jacks. The Inputs accept balanced or unbalanced sources. Just plug them in. This source is now routed to each of the four Outputs.For a single mono source feeding all headphones, connect it to either one of the INPUT jacks and engage the STEREO/MONO switch. Set the CHANNEL LEVEL controls for individual headphone levels.Never connect anything except a Rane power supply to the thing that looks like a telephone jack on the rear of the unit. This is an AC input and requires special attention if you do not have a power supply exactly like the one originally packed with your unit. See the full explanation of the power supply requirements elsewhere in this manual.WEAR PARTS:This product contains no wear parts.Converts the INPUTS from stereo to mono so that a single input cable drives both sides of the headphones. In some instances a STEREO program may be confusing for live monitoring purposes, and switching to MONO improves intelligibility by summing the Left and Right signals.The red LEDs light when the input signal exceeds the MH 4’s output capability (3 dB below maximum). Occasional flickering is acceptable.The overload point automatically varies with the headphones used.Chassis ground pointA screw is supplied for chassis grounding purposes. This unit comes with an outboard power supply which does not ground the chassis through the line cord. The MH 4 can be grounded either to another chassis which is earth grounded, or directly to the grounding screw on an AC outlet cover by means of a wire connected to this chassis grounding screw.Remote POWER supply inputThe unit is supplied from the factory with a Model RS 1 remote power supply suitable for connection to this input jack. The power requirements of the unit call for an 18 volt AC center-tapped transformer only. This is not a telephone jack. Never use a power supply with your unit other than the one supplied or a replacement approved by Rane Corporation. Using any other type of supply may damage the unit and void the warranty.PHONE Output jacksThese stereo ¼" TRS jacks accept standard¼" TRS stereo headphone plugs.POWER switch and LEDYour basic, straightforward power switch.When the yellow LED is lit, the MH 4 isready to go.Individual LEVEL controlsThese control the volume for each set ofheadphones as they are driven from theINPUTS. It’s always a good idea to keep thiscontrol turned down before plugging in apair of phones, then turn it up slowly.INPUT jacksThese are automatic balanced/unbalancedManual-4UNDERSTANDING HEADPHONE POWER REQUIREMENTSHEADPHONE SENSITIVITYHeadphone manufacturers specify a “sensitivity” rating for their products that is very similar to loudspeaker sensitiv-ity ratings. For loudspeakers, the standard is to apply 1 watt and then measure the sound pressure level (SPL) at a distance of 1 meter. For headphones, the standard is to apply 1milliwatt (1 mW = 1/1000 of a watt) and then measure the sound pressure level at the earpiece (using a dummy head with built-in microphones). Sensitivity is then stated as the number of dB of actual sound level (SPL) produced by the headphones with 1 mW of input; headphone specifications commonly refer to this by the misleading term “dB/mW.”What they really mean is dB SPL for 1 mW input.Think about these sensitivity definitions a moment:headphone sensitivity is rated using 1/1000 of a watt; loud-speaker sensitivity is rated using 1 watt. So a quick rule-of-thumb is that you are going to need about 1/1000 as much power to drive your headphones as to drive your loudspeakers since both of their sensitivity ratings are similar (around 90-110 dB-SPL). For example, if your hi-fi amp is rated at 65watts, then you would need only 65 mW to drive comparable headphones. (Actually you need less than 65 mW since most people don’t listen to their loudspeakers at 1 meter.) And this is exactly what you find in hi-fi receivers—their headphone jacks typically provide only 10-20 mW of output Power.Take another moment and think about all those portable tape players. Ever hear one? They sound great, and loud. Why you can even hear the headphones ten feet away as the teenage skateboarder that ran over your foot escapes.Power output? About 12 mW.As you can see from the chart below, headphones near 75ohms impedance produce the highest power levels from the MH 4. However, heaphone sensitivities vary widely, and are not merely a function of power.MH 4 power with all Channels driven simultaneously or with any combinationTHE LISTAs an aid in finding out how much power is available from the MH 4 Headphone Console we have compiled alisting of popular headphones. To the right is a column giving the maximum SPL obtainable using the MH 4 and any particular headphone—ultimately, it all gets down to actual SPL. The power rating really doesn’t matter at all—either it’s loud enough or it isn’t (of course it has to be clean power, not clipped and distorted). The SPL numbers shown are for maximum continuous SPL; for momentary peak SPL add 3dB.Note that the maximum achievable SPL varies widely for different models and manufacturers, ranging from a low of 107 dB to a harmful 133 dB! The table also shows there is very little relationship between headphone impedance and sensitivity, and that power output alone means nothing, since in one case 89 mW produces a maximum SPL of 107 dB, yet in another case the same 89 mW yields an SPL of 117 dB!Sensitivity dB is measured sound pressure level with1 mW of power. The MH 4 Max Power mW column is typical continuous average power, 20 Hz-20 kHz, with THD less than 0.1%.If headphones are not yet owned, or replacements are desired, use this listing as a guide for selecting head-phones with sufficient sensitivity for the maximum desired SPL.Note: headphones with an impedance of less than 32 ohms are not recommended for use with the MH 4.Manufacturer Model Impedance(ohms)Sensitivity(dB)MH 4 MaxPower (mW)MH 4 MaxSPL (dB)AKG K141M6009889117K240M, K240DF6008889107K270S7592239115K30110094225118K401, K50112094220117Audio-Technica ATH-COM1, ATH-COM2, ATH-9084090220113ATH-9104092220115ATH-P540100220123ATH-M4060100238123ATH-D4066102235126ATH-M2X, ATH-M3X45100230123 Beyerdynamic DT15025097160119DT211, DT3114098220121DT2508098240121DT411250102160124DT 53125095160116DT431, DT3314086220109DT770PRO, DT990PRO6009689115DT801, DT811, DT51125094160116DT901, DT91125098160120 Fostex T-54496225119T-77098240121T-205096233120T-405098233122 Grado SR 3254096220119Hosa HDS-7014091220114Koss A/250, A/200, A/130, TD/806098238123R/2006084238108R/100, R/456085238109R/90, HD/2, SB/1560100238123R/80, R/35S, R/20, Porta Pros60101238124R/70B, R/55B, SB/50, SB/3560101238124R/406090238114R/30S60106238130R/1060103238127TD/756095238119TD/6590101235124TD/613893212116 MB Quart QP 80530098145120Sennheiser HD 400, 433, 435, 4703294200117HD2570120240144HD4455297235121HD25SP85100235123HD265, 525, 535, 545, 56515094207117HD455, 4756094238118HD46510094225118HD 57012095220110HD580, 60030097145118 Sony MDR-V100MK23298200121MDR-8540102220125MDR-V600, MDR-D7745106230129MDR-CD103296200119MDR-CD550, CD75045100230123MDR-CD645110230133MDR-CD850, CD95032102200125MDR-CD1000, CD300032104200127MDR-D33, MDR-D55, MDR-750445104230127MDR-750663106240129MDR-750245102230125 Stanton ST PRO, DJ PRO 100032100200123Technics RP-DJ120032200Telex PH-660010589124Yamaha RH5MA3298200121RH132********RH23295200118RH36095238119RH10M40102220125RH40M32103200126Manual-5MOJO GLOSSARYbalanced line The recommended method of interconnecting audio equipment. A balanced line requires three conductors: a twisted-pair for the signal (positive and negative) and an overall shield. The shield must be tied to the chassis at both ends for hum-free intercon-nect.bandwidth Abbr. BW The numerical difference between the upper and lower -3 dB points of an audio band.clipping What occurs when a unit tries to produce a signal larger than its power supply. The signal takes on a flat-topped, or clipped shape. When an amplifier tries to go above its max power, it clips. compressor A signal processing device used to reduce the dynamic range of the signal passing through it. For instance, an input dynamic range of 110 dB might pass through a compressor and exit with a new dynamic range of 70 dB. The modern usage for compressors is to turn down (or reduce the dynamic range of) just the loudest signals. Other applications use compressors to control the creation of sound. When used in conjunction with microphones and musical instrument pick-ups, compressors help determine the final timbre by selectively compressing specific frequencies and wave-forms.connectors Audio equipment uses different styles:RCA An unbalanced pin connector commonly used on consumer and some pro equipment; aka phono plugXLR A 3-pin connector common on pro audio equipment. Preferred for balanced line interconnect; aka Cannon plug ¼" TRS 1. Stereo ¼" connector consisting of tip (T), ring (R), and sleeve (S) sections, with T = left, R = right, and S = ground/shield. 2. Balanced interconnect with the pos & neg signal lines tied to T and R respectively and S acting only as an overall shield. 3. Insert loop interconnect with T = send, R = return, and S = ground/shield. [Think: ring, right, return]¼" TS Mono ¼" connector consisting of tip (T) [signal] and sleeve (S) [ground & shield] for unbalanced wiring.constant-Q equalizer (also constant-bandwidth) The bandwidth remains constant for all boost/cut levels. Since Q and bandwidth are interrelated, the terms are fully interchangeable. decibel Abbr. dB (named after Alexander Graham Bell). The preferred method and term for representing the ratio of different audio levels. Being a ratio, decibels have no units. Everything is relative. So it must be relative to some 0 dB reference point. A suffix letter is added to distinguish between reference points:0 dBu A reference point equal to 0.775 V+4 dBu Standard pro reference level equal to 1.23 V0 dBV A reference point equal to 1.0 V-10 dBV Standard reference level for consumer and some pro audio use, equal to 0.316 V. RCA (phono) connectors are a good indicator of units operating at -10 dBVdynamic range The ratio of the loudest signal to the quietest signal in a unit or system as expressed in decibels (dB). expander A signal processing device used to increase the dynamic range of the signal passing through it. Expanders complement compressors. For example, a compressed input dynamic range of 70 dB might pass through a expander and exit with a new expanded dynamic range of 110 dB. Modern expanders usually operate only below a set threshold point, i.e., they operate only on low-level audio. The term downward expander describes this type of applica-tion.ground Any electrical reference point for measuring voltage levels. Usually a large conducting body, such as the earth or an electric circuit connected to the earth. Chassis should always be at earth potential.WARNING: SHOCK HAZARDNever use an AC line cord ground-lift adapter or cutoff the 3rd pin. It is illegal and dangerous.headroom The level in dB between the typical operating level and clipping. For example, a nominal +4 dBu system that clips at +20 dBu has 16 dB of headroom.hum Unwanted sound contaminating audio paths due to EMI (electro-magnetic interference) caused by AC power-lines & transformers getting into unbalanced, poorly shielded, or improperly grounded connecting cables. Hum has a definite smooth (sine wave) repetitive sound based on the harmonics of 50/60 Hz such as 100/ 120 Hz and 150/180 Hz.interpolating Term meaning to insert between two points. If a graphic equalizer’s adjacent bands, when moved together, produce a smooth response without a dip in the center, they are interpolat-ing between the fixed center frequencies.levels Terms used to describe relative audio signal levels:mic-level Nominal signal coming directly from a microphone. Very low, in the microvolts, and requires a preamp with at least 60 dB gain before using with any line-level equipment.line-level Standard +4 dBu or -10 dBV audio levels. instrument-level Nominal signal from musical instruments using electrical pick-ups. Varies widely, from very low mic-levels to quite large line-levels.limiter A compressor with a fixed ratio of 10:1 or greater. The dynamic action prevents the audio signal from becoming larger than the threshold setting.Linkwitz-Riley crossover The most preferred active crossover design. It features steep 24 dB/octave slopes, in-phase outputs, and flat amplitude response. Due to the in-phase outputs the acoustic lobe resulting when both loudspeakers reproduce the crossover frequency is always on-axis (not tilted up or down) and has no peaking.noise 1. Interconnect. Unwanted sounds contaminating audio paths. RFI (radio frequency interference) caused by broadcast signals leaking into unbalanced, poorly shielded, or improperly grounded connecting cables. Also by light dimmers, motor controls and computers. 2. Music. A random mix of audio frequencies not harmonically related, sounding like radio static.polarity A signal s electromechanical potential with respect to a reference. For example, a microphone has positive polarity if a positive pressure on its diaphragm results in a positive output voltage.polarity vs. phase shift:polarity refers to a signal s reference NOT to its phase shift. Being 180 degrees out-of-phase and having inverse polarity are DIFFERENT things. We wrongly say something is out-of-phase when we mean it is inverted. One occurs over a period of time; the other occurs instantaneously.Q(upper-case) Quality factor. Defined to be the ratio of the center frequency f divided by the bandwidth BW for a bandpass filter. signal-to-noise ratio The ratio in dB between a reference level and the noise floor. For example, a signal-to-noise ratio of 90 dB re +4 dBu, means the noise floor is 90 dB below a +4 dBu ref. unbalanced line An audio interconnect scheme using one wire with an overall shield. The shield must perform two functions: act as the return signal path (ground) and to protect the conductor from noise (shield). Consequently this method is vulnerable to hum & noise problems.unity gain A gain setting of one. The level out equals the level in.Manual-6SOUND SYSTEM INTERCONNECTIONRane’s policy is to accommodate rather than dictate. However, this document contains suggestions for external wiring changes that should ideally only be implemented by trained technical personnel. Safety regulations require that all original grounding means provided from the factory be left intact for safe operation. No guarantee of responsibility for incidental or consequential damages can be provided. (In other words, don’t modify cables, or try your own version of grounding unless you really understand exactly what type of output and input you have to connect.)THE ABSOLUTE BEST RIGHT WAY TO DO IT Use balanced lines and tie the cable shield to the metal chassis (right where it enters the chassis) at both ends of the cable.A balanced line requires three separate conductors, two of which are signal (+ and –) and one shield. The shield serves to guard the sensitive audio lines from interference. Only by using balanced line interconnects can you guarantee (yes, guarantee) hum-free results. Always use twisted pair cable. Chassis tying the shield at each end also guarantees the best possible protection from RFI [radio frequency interference] and other noises [neon signs, lighting dimmers].THE NEXT BEST RIGHT WAY TO DO ITThe quickest, quietest and most foolproof method to connect balanced and unbalanced is to transformer isolate all unbalanced connections. Your audio dealer can recom-mend such a transformer.The goal of transformer adaptors is to allow the use of standard cables. With these transformer isolation boxes, modification of cable assemblies is unnecessary. Virtually any two pieces of audio equipment can be successfully interfaced without risk of unwanted hum and noise.Another way to create the necessary isolation is to use a direct box. Originally named for its use to convert the high impedance, high level output of an electric guitar to the low impedance, low level input of a recording console, it allowed the player to plug “directly” into the console. Now this term is commonly used to describe any box used to convert unbal-anced lines to balanced lines.THE LAST BEST RIGHT WAY TO DO ITIf transformer isolation is not an option, special cable assemblies are a last resort. The key here is to prevent the shield currents from flowing into a unit whose grounding scheme creates ground loops (hum) in the audio path (i.e., most audio equipment). Do not be tempted to use 3-prong to 2-prong “cheater” adapters to lift grounds. This is a danger-ous and illegal practice.It is true that connecting both ends of the shield is theo-retically the best way to interconnect equipment – though this assumes the interconnected equipment is internally grounded properly. Since most equipment is not internally grounded properly, connecting both ends of the shield is not often practiced, since doing so can create noisy interconnections.A common solution to these noisy hum and buzz problems involves disconnecting one end of the shield, even though one can not buy off-the-shelf cables with the shield disconnected at one end. The best end to disconnect is a matter of personal preference and should be religiously obeyed; choose inputs or outputs and always lift the side you choose (our drawings happen to disconnect the outputs). If one end of the shield is disconnected, the noisy hum current stops flowing and away goes the hum — but only at low frequencies. A one-end-only shield connection increases the possibility of high frequency (radio) interference since the shield may act as an antenna. Many reduce this potential RF interference by providing an RF path through a small capacitor (0.1 or 0.01 microfarad ceramic disc) connected from the lifted end of the shield to the chassis. The fact that many modern day installers still follow this one-end-only rule with consistent success indi-cates this and other acceptable solutions to RF issues exist, though the increasing use of digital and wireless technology greatly increases the possibility of future RF problems.See the following page for suggested cable assemblies for your particular interconnection needs. Find the appropriate output configuration from your mixer output(down the left side), and then match this with the correct balanced or unbalanced input to the MH 4 (down the right side.) An “off-the-shelf” cable may be available or modifiable. Soldering should only be attempted by those trained in the art. SUMMARYIf you are unable to do things correctly (i.e. use fully balanced wiring with shields tied to the chassis at the point of entry, or transformer isolate all unbalanced signals from balanced signals) then there is no guarantee that a hum free interconnect can be achieved, nor is there a definite scheme that will assure noise free operation in all configurations. WINNING THE WIRING WARS• Use balanced connections whenever possible.• Transformer isolate all unbalanced connections from balanced connections.• Use special cable assemblies when unbalanced lines cannot be transformer isolated.• Any unbalanced cable must be kept under ten feet (three meters) in length. Lengths longer than this will amplifythe nasty side effects of unbalanced circuitry's groundloops.This information was condensed from Rane Note 110,“Sound System Interconnection”.

iZotopeOzone4说明书
iZotope Ozone 4母带处理巨头-----臭氧操作说明书界面小介绍：首先展现在我们面前的是这个界面，也就是软件第一次启动时候，给我们的一些预置的效果，通过单击其中一个，然后点击OK即可使用之········其实预置是个好东西呀·········我倒不是推荐大家去用预置，不过研究下官方的预置参数，确实能学会不少东西。
然后双击预置的参数，可以给他改个名字。
通过sort by 里面的选项调节排列方式。
Name 按照名字也就是按照字母顺序，Last modified最近修改，Last used就是最近使用。
然后就是这一块，对预置进行编辑的地方。
具体我就不多赘述了。
Add 添加预置Remove 移除预置Update 升级\更新Compare 这个是对比，用过waves的朋友们可能了解这个东西，类似waves里的A-BNew Foder 看到New 这个大家应该明白了吧？就是新建文件夹的意思新建个预置文件夹Show at start up 就是传说中的启动时显示，当然，这个你可以把X点掉。
点掉后启动后就不会出现预置文件了，如果需要加载预置的话，你可以点击右下方的presets按钮，来弹出预置文件。
接下来我们来介绍这一块的功能Change folder改变预置的文件夹位置More presets 更多预置Undock 非窗口停靠，可以使预置的文件目录脱离开臭氧，单独出现一个窗口，如图所示：Dock 就是窗口停靠的意思，可以使预置文件夹目录恢复到原来在臭氧中的位置。
OK Cancel 就是确定和取消的意思了。
然后我们可以看到随着你选择的预置文件的转换。
预置文件下方的选择也有相应的变化。
接下来我们介绍一下这些参数的含义。
Global 全局Crossover 交叉，其实就是类似W A VES C4中的分段分区域的功能Reverb 混响，这个没什么疑问了Exciter 这个是激励的意思，类似BBEImager 图像机Meters 电平表EQ 均衡Maximizer 达到最佳化Dynamics 动态Dither 抖动然后旁边的Advanced是高级选项，只有在非窗口停靠的模式下才可以点击。
