When powering up, the amplifier should be the last to beswitched on, when powering down, please ensure the amplifier is switched off first.∙The Pulse PLA series features Signal Clip LED’s to indicate when the amplifier is within 3dB of “clipping”. This indicates the amplifier is receiving itsmaximum input signal and the gain at source should now be reduced.∙Clipped signals are harmful to speakers and amplifiers, they will also sound “distorted” to the ear. Care should be taken to avoid clipping the signal at any point during the signal flow.∙The amplifier features a PROTECT mode indicated by the LED on the front panel. Should the amplifier enter PROTECT mode at any point please switchoff the amplifier immediately. Once powered down the input signal should be turned down to the minimum and the load (speakers) disconnected. At thisstage the speakers and output cabling should be checked for faults/damageand if they are in good working order may be reconnected. The amplifier canthen be powered up again and the input signal increased. Should the amplifier remain in PROTECT mode permanently this indicates a fault and the amplifier will require servicing or repair by an engineer.∙The input connectors on the Pulse PLA series are standard 2-pole unbalanced6.35mm (1/4”) jack sockets.∙Choose speaker cables carefully – please use cables with cores of minimum1.5mm2 and under 10m in length to prevent power loss.∙Check all cables (speaker, signal and mains) for damage, loose terminals or potential short circuits on regular occasions.∙Speaker wires carry high voltages; care should be taken to ensure no bare wires can be touched as this may result in electric shock.∙The Pulse PLA Series features a dual use locking speaker connector on OutputA – this allows both amplifier channels to be accessed using one standardlocking speaker connector.

24V电源设计工具用户指南说明书
A great deal of detail work is demanded if you want to dimension your 24 V power supply to optimum effect: For all the automation components supplied, you must not only determine the rated current, for example, but also take the inrush current into account. This means, for example, time-consuming searches by hand through catalogs or data sheets. To meet precisely this demand, it has now been made possible to design a power supply unit in the Totally Integrated Automation (TIA) selection tool. This means that, in just a few steps and clicks, you quickly find your way to the suitable power supply for your needs.The profit is in the detailThe increasing level of industrial automation demands not only efficiency, but also a reliable 24 V supply to automation components during operation and in the event of a fault. The solution is the use of a reliable power supply. Meanwhile, there is also the painstaking manual task of collecting and logically processing figures. Here too, the level of complexity soon pushes users to their limits. This is because an optimally dimensioned power supply on the one hand offers you the security that itreliably delivers sufficient current under all operating conditions and, on the other hand, is not over-dimensioned, which would have a negative impact in terms of price and space requirements in the control cabinet. The TIA Selection Tool is designed to help you get things right when selecting a power supply, even at the planning stage. The TIA Selection Tool not only enables suitableThe right choice for a sustainable supplyPower Supplypage 1/4devices to be selected for Totally Integrated Automation, but also configures them so that they are ready to be ordered easily through the Siemens Industry Mall.In comparison with conventional tools, this tool not only manages to combine the configuration of different automation products, but can achieve far more benefits for the user.Convenient selection via the device family viewSelection of the "device family" in the TIA Selection Tool provides a choice of different automation components such as controllers, I/O systems, HMI devices, industrial PCs, drive systems, switchgear, software, communication components, power supply units, and industrial identification systems. In addition, a Profibus and Profinet network can be selected on the basis of associated cables and connectors. (Fig. 1). Under the "power supply" heading, all 24 V power supply units of the Sitop compact, LOGO!Power, Sitop lite, Sitop smart and Sitop modular product lines are listed. The UPS1600 uninterruptible power supply can also be selected by means of the TIA Selection Tool. When selecting this, additional parameters such as load current, buffer time or ambient temperature can be defined. The user has the further option of selecting the Siplus versions and the PSU8600 power supply system (Fig. 2). In addition, a matching power supply in the Simatic design can be implemented in the respective product catalog of the controller.Fig. 1: Simple selection of a power supply using thedevice family viewFig. 2: Possible configuration of the intelligent PSU8600 power supply systemAfter choosing the appropriate automation components, you are automatically guided to the selection wizard. It is also possible for a product to be selected on the basis of technical features via a hardware catalog. In addition, this view offers a comparison component, so that with a simple click several power supply product lines can be compared directly with one another. For expansion of the selected power supply, it is also possible to select a matching redundancy and/or selectivity module (Fig. 3). These can be added by simply clicking on the accessory for the selected power supply. From this product selection in the catalog, the TIA Selection Tool defines a complete list of orders. The list of orders can then be transferred directly to the shopping cart in the Siemens Industry Mall and the product list can be exported in various formats, for example Excel. In addition, you can also request relevant CAX data via the CAX Download Manager.page 2/4page 3/4Fig. 3: Selection of accessories such as a selectivity module for a power supply is possible at any timeNew intelligent 24 V load view in the TIA Selection ToolAlthough you can determine power supply units for automation applications with comparatively few parameters, users have sometimes asked: "What is the current demand during operation?" or "What is the inrush current?". Until now, it was only possible to determine a demand-compliant power supply for automation components with considerable effort. Users who wanted to determine this demand first required a variety of technical data of the individual components, which usually involved a great deal of effort. This should, however, actually be easier to select and determine; ideally, with a suggestion for an appropriate power supply for the specified or selected 24 V load. The TIA Selection Tool also promises assistance in this area.The easy way to find the right power supplyWith the 24 V load view, the appropriate Sitop power supply unit can already be determined for selected automation products. The power requirement of the 24 V loads is calculated automatically and is taken into consideration as soon as the power supply unit is selected. The overview page of the 24 V load view of the TIA Selection Tool displays the automation components previouslyselected by the user. With one click, any power supply unit that has not yet been specified can quickly be added (Figs. 4 and 5). To this end, an additional screen provides instructions on adding a power supply unit. By simply dragging and dropping, the loads can then be connected with one or more power supply units. In doing so, the tool automatically determines the total of the rated and peak currents. The user, however, is free to decide which loads are to be includedin this circuit.Fig.4: Configuration of automation components with a power supply in the 24 V load viewFig. 5: Configuration of two power supplies that supply different loadsUsing the "Edit" function, the selection wizard for the appropriate power supply unit can be started. Only power supply units that deliver the total power required by the loads to be supplied are available for selection. Further parameters can also be defined. Apart from the input voltage (phase selection) and a specific preferred series of products, it is alsopossible to specify a spare capacity forfurther loads or future expansions as apercentage. Furthermore, thespecification of a rated coincidencefactor takes into consideration the factthat the devices in a plant are never allactivated simultaneously at full power(Fig. 6).Fig. 6: Intuitive selection of technical data such aspower reserve, coincidence factor, input voltage,product line, etc.Lastly, there is the possibility of settingup the power supply on a redundantbasis. On confirmation of thisfunction, the appropriate redundancymodule is offered.Flexibility is an essential componentof planningFurthermore, the tool offers twoversions of the configuration atpresent. On the one hand, the TIASelection Tool can be downloaded andinstalled on Windows computers. Inaddition, there is the option of usingthe Cloud version of the tool. This canbe started directly in the browser ofmobile devices. The use of webbrowsers such as Safari, Chrome andFirefox is recommended for thispurpose. The advantage of projectsstored in the Cloud is that you canwork on them using a tablet when youare traveling or from your PC at home.In order to be able to exploit the fullfunctionality, it is recommended inboth cases that an account be set up inthe Siemens Industry Mall. In this way,after creating a bill of materials orordering list, the user can immediatelyorder the products through theSiemens Industry Mall.。

功放的用法与使用注意事项
功放的用法与使用注意事项功放是音响系统中最基本的设备，它的任务是把来自信号源的微弱电信号进行放大以驱动扬声器发出声音。
功放的使用也需要注意一些事项。
以下是由店铺整理的功放的用法的内容，希望大家喜欢!功放的用法AUdio INPUT是音频信号输入端口，3个都是。
旁边的3个是5、1声道的音源输入端口，平时听、唱歌接AUdio INput这3组中的一组就可以了，5、1声道立体声效果好，看电影合适，但要分几组信号输入。
输出是右边的5组接线端柱(SPEAKERS SYSTEM)，从左到右分别是右声道、左声道(左右为主声道)、中置、环绕右、环绕左。
可以接5个音箱，红色为正极，接音箱正极，黑色为负极，接音箱负极。
电脑声卡的输出信号线连接功放的AUdio INput，功放的输出端连接音箱。
无线话筒接入无线咪接收器，输出信号接入功放就行了。
如果有个前级效果器就更方便了，可以把声卡信号和无线咪接收器的信号都输入到前级效果器里，效果器输出再接入功放，这样更好，通过效果器调节音质声音会更好。
功放的作用功放的作用就是把来自音源或前级放大器的弱信号放大，推动音箱放声。
一套良好的音响系统功放的作用功不可没。
功放，是各类音响器材中最大的一个家族，其作用主要是将音源器材输入的较微弱信号进行放大后，产生足够大的电流去推动扬声器进行声音的重放。
由于考虑功率、阻抗、失真、动态以及不同的使用范围和控制调节功能，不同的功放在内部的信号处理、线路设计和生产工艺上也各不相同。
功放的保养方法1、用户应将功放放置在干燥、通风的地方，避免在潮湿、高温、油烟化学制剂有腐蚀性的环境中工作。
2、用户应将功放放置在安全、平稳、不易掉落的台面或机柜中使用，以免碰损或跌落在地上，将机器损坏或引起更大的人为灾害，如火灾、触电等。
3、用户应将功放避开电磁干扰严重的环境，如日光灯镇流器老化等放射的电磁干扰将会引起机器CPU程序错乱，导致机器不能正常工作。
4、PCB布线时注意，电源脚与水溏不能太远,太远可加1000--470U放在它脚边。

功放机按键说明书
功放机按键说明书篇一：音响操作说明音响操作说明针对于本系统，具体操作如下： 1. 话筒及音乐输入连接：调音台可以接入有线话筒、无线话筒、DVD、电脑音频等；有可种可以接入的插口，方便进行连接（如下图所示）。
第1路到第8路一般接入话筒，第13到16路为DVD等音乐信号输入；第9路到第12路比较特殊，即可以接入话筒，也可以接入DVD等音乐信号（已经标明L、R声道），只是接口不一样而已。
注：1、如果上面的卡侬口已经接入设备，就不要再用下面的单插插口，也就是说，这一路里面只可以接入一路音源；下面的INSERT插口，本系统用不到。
2、如果要接入普通的会议话筒，可能需要48V供电，那么本调音台具备此功能，只需要把调音台的48V供电开关打开即可，如下图所示；2. 开启系统：先打开第一台电源时序器，电源时序器会依次给所接设备供电；等第一台电源时序器的8路电源依次打开完毕，再打开第二台电源时序器，同样，等8路电源全部打开方可进行其他操作。
注：专业音响设备具有开关顺序，开启时顺序为：音源设备（如DVD、话筒接收机等）、周边设备（如调音台、均衡器、效果器等）、功放。
否则的话，可能会产生“嘭”的声响，以至于损坏设备。
3. 播放音频、视频：首先把调音台右下角总音量的推子调整到合适的位置（如图一所示），高度最好不要超过0刻度；然后打开DVD 机，把光盘放入，让DVD处于读碟播放状态；找到调音台对应DVD接入的那一路，把方块透明的开关按钮按下，使其处于点亮状态，再按下下方的红色ST按钮；然后轻轻从下方往上推长方形的音量推子，直到音量足够为止（如图二所示）。
高中低音调整：正常情况下，无需调整音乐音频，因为DVD或电脑放出来的都是原始音频，如果想调整音乐的高中低音，可以通过调音台自带的简单均衡器进行调整（如图三所示），上面的为高音旋钮，中间的为中高频旋钮，下面的为低音旋钮。
音视频矩阵切换：如把第1路音频、视频切换到第2路输出，那么操作方法是：按AV键然后从右侧上边的一排（输入键）按下1键，然后再从下面一排（输出键）按下2键，最后再按下ENTER 键即可。

This amplifier is designed to offer high quality, dependable service for mobile and installed systems. Please read this manual fully and follow the instructions to achieve the best results with your new purchase and to avoid damage through misuse.To prevent the risk of fire or electric shock, do not expose any components to rain or moisture.If liquids are spilled on the casing, stop using immediately, allow unit to dry out and have checked by qualified personnel before further use. Avoid impact, extreme pressure or heavy vibration to the case No user serviceable parts inside – Do not open the case – refer all servicing to qualified service personnel.Safety• Check for correct mains voltage and condition of IEC lead before connecting to power outlet • Use double insulated speaker wire with adequate current rating for 100V speaker connections • Do not use 8Ω and 100V terminals at the same time•Do not allow any foreign objects to enter the case or through the ventilation grillesPlacement• Keep out of direct sunlight and away from heat sources • Keep away from damp or dusty environments• For rack-mounting, ensure adequate support for the weight of the amplifier• Ensure adequate air-flow and do not cover cooling vents at the front and rear of the amplifier • Ensure adequate access to controls and connectionsCleaning• Use a soft cloth with a neutral detergent to clean the casing as required•Use a vacuum cleaner to clear ventilation grilles of any dust or debris build-ups • Do not use strong solvents for cleaning the unitFront panel1. MASTER volume control2. POWER, SIGNAL, PEAK LED indicators3.Power switchConnection and setupConnect the rear IEC inlet (6) to the mains using the supplied mains lead (or an equivalent approved type). Ensure that the voltage is correct as indicated on the voltage selector (5) and that the mains outlet is switched on.Alternatively, the VS120 and VS240 can be powered by a 24V battery, such as a lorry or boat battery, by connecting the “+” and “-” of the battery to the 24Vdc INPUT (7) on the rear panel. Ensure that DC cables are capable of handling the current (10A min. recommended)The VS series amplifiers are intended to be fed from a mixer or mixer-amplifier signal output, providing additional power amplification for 100V speaker systems. The signal input should be connected to the SLAVE IN dual RCA connectors (12) on the rear panel. The VS series slave amplifiers are mono, so any stereo input signals will be summed together to provide a monaural output. Further slave amplifiers can be connected from the rear SLAVE OUT RCA sockets (11), allowing banks of amplifiers to operate together in large public address systems.Speaker outputsThe VS series slave amplifiers can be used either as 100V line amplifiers or standard low impedance power amplifiers. These 2 configurations cannot be used together, so it is important to decide which method will be used at the start.4. Ventilation grille - do not cover5. Mains voltage selector switch6.

SLAVE OUT connectors (RCA) 12.SLAVE IN connectors (RCA)100V line systemsFor 100V line systems, connect the amplifier to the first speaker in the system using double-insulated speaker wire, which has adequate current rating to handle the total output of the amplifier.Connect the “100V” (10) output terminal to the positive (+) connection of the speaker and “COM” output (8) to the negative (-) connection of the speaker. Connect further speakers in parallel to the first speaker with all positive terminals and connected together and all negative terminals connected together as shown below.A 100V line speaker system can comprise of many speakers connected together. The determining factor for how many speakers can be used on a single amplifier is the power rating. For most purposes, it is advised to connect as many speakers as needed with a combined wattage of no more than 90% of the amplifier’s output power rating.The terminals of a 100V speaker are connected to a transformer and in some cases, this transformer may be “tapped” for different power ratings. These tappings can be used to adjust the wattage (and output volume) of each speaker in the system to help achieve the ideal total power of the system for the amplifier.Low impedance systemsThe VS series slave amplifiers can provide an output for a single 8Ω speaker by connecting the “8Ω” output (9) to the positive (+) speaker connection and “COM” output (8) to the negative (-) speaker connection. It is important to ensure that the speaker load is no less than 8Ω and that the power handling of the speaker is equal to or greater than the output power of the amplifier.OperationWhen all connections to the amplifier are made, turn the MASTER volume control (1) fully down and switch on the power (3) and the power LED will illuminate. Ensuring that the signal is active on the SLAVE IN inputs, turn up the MASTER gradually to the maximum required volume level.The output of the amplifier is represented on the SIGNAL LED and when the amplifier is running at its peak output, a PEAK LED will illuminate. Care should be taken that the Red PEAK LED is only lit momentarily during use. Anything longer than a short flash of this LED may be indicating distortion or clipping of the output signal and the MASTER volume should be turned down.SpecificationsVS120 VS240 VS360 Power supply 110/230Vac, 50/60Hz (IEC) DC power24Vdc screw terminals 24Vdc screw terminals N/AOutput power: RMS 120Wrms 240Wrms 360WrmsOutput: Line RCA slave out Input RCA slave in Controls Master volume THD<1.0%Dimensions 433 x 363 x 89mm 433 x 363 x 89mm 433 x 403 x 89mm Weight8.88kg 10.06kg11.60kgTroubleshootingEnsure IEC lead is in good condition and connected properlyIf 24Vdc power input is being used, check battery is chargedNo power LED on control panel Ensure POWER switch is on and check mains inlet fuseCheck input signals and condition of input connection leads Power LED is on but no other LEDs and no output Check MASTER volume control is turned upCheck speaker output terminals are connected correctly POWER and SIGNAL LEDs lighting but no output Check speakers are working (test on another amp if available)Check level of input signal is not too highOutput is very loud or distortedReduce MASTER volume levelCheck SLAVE IN signal level is not too lowIncrease MASTER volume level Check for quiet recording of media files on USBOutput is working but at very low level Check VOX override is not unintentionally suppressing audio playback Ensure cooling vents are clear from debris and dustCheck that 4Ω or 8Ω speakers are not connected to 100V terminalsEnsure total 100V speaker wattage is lower than amplifier ratingEnsure that 100V and 8Ω speakers are not both connectedAmplifier overheating Ensure that total load connected to 8Ω output is not less than 8ΩDisposal: The “Crossed Wheelie Bin” symbol on the product means that the product is classed as Electrical orElectronic equipment and should not be disposed with other household or commercial waste at the end of its useful life.The goods must be disposed of according to your local council guidelines.Errors and omissions excepted.Copyright© 2014.
