It may only beconnected to other equipment that is installed inside a building.Do not open the housing of the speaker; doing so may reduce thequality of the sound.2 Dolev 8 - Getting Started2.2 Recycling Kramer ProductsThe Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aimsto reduce the amount of WEEE sent for disposal to landfill or incineration byrequiring it to be collected and recycled. To comply with the WEEE Directive,Kramer Electronics has made arrangements with the European AdvancedRecycling Network (EARN) and will cover any costs of treatment, recycling andrecovery of waste Kramer Electronics branded equipment on arrival at the EARNfacility. For details of Kramer’s recycling arrangeme nts in your particular country goto our recycling pages at /support/recycling/. Dolev 8 - Getting Started 33 OverviewThe Dolev 8 is a high-quality, high-fidelity, studio grade speaker designed andcrafted for superior clarity and detail for high-end applications or any other task thatrequires precise, accurate and detailed sound, even at high volume levels.The Dolev 8 ensures that you hear exactly what is happening in the music andreveals all the original nuances of the sound, without adding to or subtracting fromthe signal. Premium components, an advanced cabinet design, and efficient bi-amplification come together to provide superior full-range sound—from crystal-clearhighs, to deep, rich bass tones. You can be confident that your music sounds itsbest in any listening environment.The Dolev 8 features:∙ A Two-way, bass-reflex, bi-amplified speaker∙ A 8” fiberglass woofer and a 1” neodymium dome tweeter∙ 1 unbalanced and 2 balanced audio inputs∙Four-position high-frequency gain control∙ A volume adjustment control knob∙Magnetic shielding4 Dolev 8 - Overview4 Defining the Dolev 8This section defines the powered Dolev 8:Figure 1: Dolev 8 Active 2-Way, Bi-Amplified Studio-Grade SpeakerDolev 8 - Defining the Dolev 8 55 Installing the SpeakerThis section explains how to:∙Choose the best location for your speakers (see Section 5.1)∙Setup mid/near-field (see Section 5.2) or far-field (see Section 5.3) Installation∙Install the speaker (see Section 5.4)5.1 Choosing the Best LocationFor optimum installation:∙Speakers should be positioned at least 50cm from the walls∙Install the Dolev 8 so that the center point between the tweeter and the woofer are at ear level. If required, use a speaker stand∙If required, use sound absorbing materials around the room∙Place the speaker facing towards the listener to minimize the distance and reflections from the walls and get the best stereo image5.2 Setting up Mid/Near-Field InstallationMid-field or near-field installation is usually directed towards a specific listener orlisteners in a specific location of the room. To maximize your listening experience:1. Make sure that the speakers are set at head height (whether you will be usingthe speakers sitting down or standing up).Figure 2: setting the Dolev 8 at head height6 Dolev 8 - Installing the Speaker2. Position the speaker at an angle so that together with the listener, anequilateral triangle is created.3. Try to keep the speakers at a distance of about 50cm from the walls4. Try to keep a distance of about 1.5 to 2 meters between the speakers.Figure 3: Dolev 8 Optimum positioningiNote that even though the illustration in Figure 3 shows twospeakers each Dolev 8 package includes one speaker.5.3 Setting up Far-Field InstallationFar-field positioning is suitable for a large amount of listeners (unlike the near-fieldpositioning where the speakers are directed at a specific listener). To maximize thelistening experience:1. Make sure that the speakers are facing the center of the room.2. Make sure that both speakers are placed along the same wall in the room(not facing each other).3. Aim to achieve the largest sweet spot.For optimum results we recommend that you either experiment and locate thesweet spot by trial-and-error or alternatively, consult an acoustic engineer.Dolev 8 - Installing the Speaker 75.4 Installing the SpeakerTo install the speaker, do the following:1. Connect one of the following inputs:▪An unbalanced input (for example, a computer sound card, portableplayer or DVD/CD player – C-A35M/2RAM) to the UNBALANCEDINPUT RCA connector▪ A balanced input (for example, a professional mixer or audio interfaces) to the BALANCED INPUT 6.35mm TRS connector▪ A balanced input (for example, a professional mixer or audio interfaces) to the BALANCED INPUT XLR connector2. Set the volume on the Dolev 8 to 12 o’clock (0dB)3. Connect the power.4. Set the volume on the input source to the minimum.5. Switch the Dolev 8 power on.6. On the input source, increase the volume control slowly until the desired levelis achieved.7. Adjust the high frequency response according to the room conditions:▪ A heavily dampened room requires raised high frequencies▪ A resonant room requires reduction of the high frequencies8 Dolev 8 - Installing the Speaker6 Technical SpecificationsDolev 8 - Technical Specifications 9For the latest information on our products and a list of Kramer distributors, visit our Web site where updates to this user manual may be found.

马尔杰尔30周年纪念电子管音箱手册说明书

1use. It allows you to control your amp’s channel switching (1,2 or 3) via MIDI program change messages. The Anniversary amp has an internal memory and can store Channel 1,2 or 3 selection in 128 MIDI addressable patches. These correspond to the 0 - 127 MIDI PROGRAM CHANGE message.Rear Panel FeaturesThe rear panel of the Anniversary amplifier is the most comprehensive that we have ever produced. Inaddition to the connection and control facilities there are a number of major innovations that directly affect the sound and performance of the amplifier. As your sound is personal to you, it is important to try thedifferent options for the most suitable settings for your style.34. Footswitch Socket Accepts the connecting lead from the three way channelswitching footswitch (which is included with your unit).35. MIDI-In Socket For connection from an external MIDI device.36. Balanced Compensated XLR OutputBalanced output featuring Marshall line level SpeakerEmulation for accurate sound reproduction directly throughrecording equipment or PA (see operational note C).37. Compensated Output Level ControlProvides volume level control of the signal from item (36).Operational Note C: Speaker EmulationThe Marshall speaker emulation circuit provides a signal for direct connection to PA or recording mixers, that retains the true character of the amp driving a cabinet. The quality of this emulation is so high that ‘miking up’ cabinets should no longer be necessary, saving you both time and money, and guaranteeing you a great direct guitar tone.This output is active even when the power amp mute switch (item 39) is activated. Although this power amp mutingallows the amp to be used without speaker cabinets as with all valve amplifiers, it is wise to keep the cabinet connected.38. Uncompensated Line Output Line Out suitable for linking to further amplifiers to extendthe system.39. Uncompensated Link Selection SwitchWhen pushed in, this switch mutes the internal poweramp allowing operation as a pre-amp, switching in alsoactivates the line input to the power amp.40. Line Input Line level input jack to take an external pre-amp thususing just the power stage of your amplifier.Operational Note D: Series effects optionItems 38 & 40 can also be used as a 2nd series effects loop (See operational note F). The selection switch (Item 39) will switch the loop in or out of the circuit, but will not mute the power amp.41. Effects Send Trim Channel 1 Provides -10 to +4db level control of the effects sendfrom Channel 1 only.42. Effects Send Trim Channel 2Provides -10 to +4db level control of the effects sendfrom Channel 2.Operational Note E: Effects level balancingOn 41 & 42 - When setting up the effects loop, the effects processor’s level controls should be set up against the lead channel -3 and matched using switch (44), then channels 1 & 2 set up via the trim controls for an effects send balance.If desired, more or less sound level can be set for differing amounts of effected signal.543. Series/Parallel Selection Switch Selects series or parallel effects loop operation. Seriesconnection is most suitable for Graphic Equalizers,compressor limiters etc. Parallel connection suits delay,reverb and chorus effects. It is generally not advisableto link distortion effects through the loop. Operational Note F: Effects LoopThe main effects loop on this amplifier can be configured either as a series or a parallel loop by using theseries/parallel selection switch (item 43). The parallel loop (switch out) splits the pre-amp signal into two, retaining the direct signal within the amplifier itself, whilst sending a parallel signal out to the effects processor. By turning the direct signal within the processor to zero only an effects signal is returned to the amplifier where it will be mixed back in with the direct signal. This leaves the original direct signal uncoloured by any circuitry within the processor. By using the effects level control (item 28) your ideal mix of dry and effects signal can be easily set up.The series loop (switch in) diverts the whole pre-amp signal through the effects loop and switches off the internal direct signal. The effects level control (28) now acts as an overall master level control.In terms of application, units that are time based (eg Chorus, Delay, Reverb etc) are best suited to the parallel loop. Real time effects (eg. Graphic or Parametric EQ, Compressors etc.) suit series loop operation.It is worth noting that the line in (40) and line out (38) circuit could be used as a series effects loop at 0 dBm, giving you the ability to use both types of loop simultaneously.44. Loop Level Selector Switch Selects the general level of the effects loop (-10 or+4dB) to match processor linked to (45 & 46)45. Effects Send Jack Output for connection to the input of an externaleffects processor.46. Effects Return Jack Input for connection from the output of externalprocessor.47. Damping Select Switch Three position switch to select high, low or autodamping positions. (See operational note G). Operational Note G: Damping ControlThis unique feature controls the power amp damping. Effectively this is the way that the amplifier drives the speaker. High damping gives tight speaker movement and is ideal for clean sounds, where a precise and defined response gives sweet clear picked notes and chords.Low damping, with greater speaker movement, suits breathing heavy overdrive and full distortion. In the auto position the amp automatically selects high damping for clean selections and low damping for crunch and lead. It is probably best to leave the amplifier in auto mode for normal use.48. Power Selection Switch Two position switch to select high power (all 4 valvesworking) or low power (2 valves working). The amplifiermust be switched to standby before selection.(Seeoperational note H).Operational Note H: Power selectionThis useful feature gives excellent flexibility for all playing situations. When switched to half power, with only 2 valves working, these two valves will be driven harder than normal and will therefore have a shorter working life. If a low power selection is required for long periods then it would be better to use the pentode/triode switch (Item 52). ‘Triode’operation will give a slightly different tone to half power. 4 valves give 100 Watts in pentode - 50 Watts in triode. 2 valves give 50 Watts in pentode - 25 Watts in triode.649. Output Fuses With LED Fail IndicatorsIn the event of valve failure the HT fuse will blow toprotect the amplifier from damage. The LED will indicatewhich valve pair is faulty. The Marshall “Failsafe” circuitallows the amplifier to continue running on two valves(providing it is not switched to half power), to get you tothe end of the gig.50. Loudspeaker Outputs Twin loudspeaker output jacks. It is important that thespeakers used are correctly wired and that the impedanceis correctly selected. Also ensure that the speakers arecapable of handling the full power of the amplifier. Thecabinet must be connected before switching on the standbyswitch.51. Impedance Selector Switch Selector to ensure correct match of cabinet impedanceto the amplifier (see impedance chart on page.9).52. Pentode/Triode Selection Switch“Triode” operation gives half the rated power output(Triode operation also gives a smoother tone) and“Pentode” operation provides full rated output. (Seeoperational note I).Operational Note I: Pentode/triodeThis feature is particularly useful when tailoring your system to suit different sized venues and recording applications. When switching this function the standby switch should always be switched off. The same also applies to items 39, 44, 47, 48 & 51.53) Mains Input & Fuse Socket for connection from the mains. Always ensurethat the fuse matches the labelling on the amplifier’srear panel. If you have any doubts contact your dealeror a qualified technician.7Footswitch OperationThe three way footswitch provided with your Anniversary amplifier is for channel switching between the three channels. Connection should be made to the DIN connector on the rear panel of the amp. An LED above the switch corresponds to the channel which has been selected. Switching can also be achieved via MIDI. (See operational note B).Speaker ConnectionThe type of cabinet and speakers has a fundamental effect on the quality of your sound. Also vitallyimportant is the matching of speaker impedance to the amplifier. Incorrect matching will impair theperformance and eventually damage the amplifier.Impedance is usually marked on the cabinet input socket. If you have any doubts, have the speakerschecked by a qualified technician. When using a single cabinet the amp and cabinet should be identical(e.g. 16 Ohm 4x12 cab = 16 Ohm amp selection). If two 16 Ohm cabinets are used, then the amplifiershould be switched to 8 Ohms. Where two 8 ohm cabinets are employed the amp should be switched to4 Ohms. A speaker load below 4 Ohms cannot be used. Following these simple rules should maintainlong life and minimise amplifier servicing requirements. Unlike solid state amps, valve amplifiers don'tincrease in power as speaker impedance is lowered.Operational Note J: Impedance switchingIt should be noted that although the output transformer has 3 impedance connections, only two are switchable from outside the amplifier. These are 16 ohm and 8 Ohm on heads and 8 Ohm and 4 Ohm on combo’s. If your particular application requires this to be different, the transformer connections can easily be altered by a qualified technician.Marshall Cabinet ChartIn some cabinets the speaker type may vary (refer to rating plate for correct impedance).8 Except in US8Trouble Shooting GuideIf you have a problem with your amplifier, it is always best to let a fully qualified approved techniciancheck it over. Regular servicing should prevent any major breakdowns and is an extremely beneficial long term precaution.Often it is the simplest thing that needs attention and it may not be possible to get technical assistance. In this case you may be able to keep the amp running at least until the end of the show. The greatest care should be taken, before removing the back panel, that all mains power is disconnected. Also remember that even after short periods valves will become very hot.Phase splitter9The following list outlines some of the most obvious problems and causes.PROBLEM/SYMPTOM/CUREValves And Pilot Light On, But No Sound.1.Check valve fuse fail lights to see if HT fuses are blown. If they are, replace them with the same valuefuse. If they blow again replace all the power valves if possible.2.Check standby switch.3.Check that the series/parallel switch and power amp mute switch are both out, unless their operation isintended.Constantly Blows HT Fuses.Check the output valves; If they need replacement use matched sets and replace all power valves if possible.Have a service centre check the bias on the output valves. If it’s too low the amp will not clean up. If it’s too high it will stay too clean no matter how loudly you play.High Pitched Whistle At Hi Gain SettingsMost likely this is a microphonic pre-amp valve. Replace if necessary.Rattling Noise From Head Or Chassis99% of the time this is caused by the spring output valve retainers jangling against the valve. Gently bend the spring holders out a fraction.No Sound, Lights, Hum, Etc.1. Check mains fuse, but never with the amp plugged in.2. Make sure the amp is plugged in.Quick HintSomeday, probably at a most inconvenient time, you will blow a fuse or your valves will go. This is noreflection on any amp, valves have a definite lifespan. Always make sure you have replacements, just like you carry spare strings, or you could be left stranded. Always thoroughly check speaker leads to ensure that (A) they are properly connected and (B) they are fully working. Also, use good quality guitar leads and check them regularly.Spares And AccessoriesSuperb engineering is a part of Marshall tradition and your amplifier is built to withstand the abuse of a working musicians heaviest demands. However it is worth remembering that at it’s heart, your amplifier is full of electrical components and glass bottles. If you think of it as an extension to your guitar and treat it accordingly, then long life and small service bills should be the norm. Using only Marshall valves asreplacements will give you optimum performance from your amplifier and will remove the need for any re-biasing by a technician.In the event of component damage Marshall agents worldwide maintain a stock of spares and accessories capable of refurbishing your road-worn beast!10。

The information in this manual hasbeen carefully checked and is believed to be accurate at the time of publication. However, no responsibility is taken MCM-8 IIPRELIMINARY USER GUIDE v1.0*Modules 73 JR II not includedMCM8 II VS MCM8In 2015, Heritage Audio set a new standard in 500 Series enclosures with the addition of the OST technology. Further, we introduced the MCM8, a true transformer-based voltage summing mixer for 500 Series modules.Hundreds of units later, we have taken all our customer´s feedback and included it in the new version, the MCM8 II.The main differences in between this version and its predecessor are:-Extra 500 series button per channel, allowing to bypass the 500 series module when mixing if desired. It also allows for quick comparisons in between processed/unprocessed signals. It also makes using the mixer with empty slots quite easier. Justun pressing the 500 button allows for this type of operation.-Significant lower noise: A highly innovative, new quasi-balanced voltage summing topology sets the noise floor of the new MCM8 II touching the theoretical minimum.No more hiss into your mixes!INTRODUCTIONThe MCM-8 II is an OST TM 8 channel 500 Series Enclosure WITH mixer functions.OST is a Heritage Audio proprietary technology which eliminates module’s interaction through the power supply feeding each slot with independent supply stages.The mixer follows a passive voltage summing topology, having the gain loss restored by a classic ´73 type class A output stage.*Modules 73 JR II not includedUpper row on the front panel is dedicated to the 8 mixer’s main inputs.Controls per channel are as follows:-ON: When pressed, the output of the slot is added to the mix bus. When depressed, it’s muted.-“500”: When pressed, the signal going to the mixer section is taken from the output of the 500 series module, while when not pressed, it is taken from the input of theenclosure. This allows bypassing the module when summing, or using the mixer withan empty slot.-FADER: Attenuates the signal sent to the mix bus from unity to minus infinity. Fader all clockwise means unity gain, whilst 12 o’clock means an approximate 20 dB ofattenuation. (or -20dB of gain).-PAN: Places the signal within the stereo spectrum, left, center, right or any intermediate setting. The panoramic law follows a standard in which if a 0dB signal ishard panned, it is -3dB when center panned.Lower zone is dedicated to the 500 series modules. Any module following the API protocol (both mechanically and electrically) will be compatible with the unit.Right part of the unit is dedicated to the mixer’s center section, as follows:-VU Meters: Measuring the average level at the master outputs.-Master Fader: Attenuates the Mix’s output from unity to minus infinity. The control has a stepped feel for easy recall of settings. Fader all clockwise means unity gain,whilst 12 o’clock means an approximate 20dB of attenuation.At the bottom right there are LEDs showing the correct status of the external power source.Upper row on the back panel corresponds to the individual XLR and combined DSUB channel outputs.Lower row corresponds to the individual XLR and combined DSUB channel inputs.Both DSUB connectors are wired following the TASCAM protocol.Stereo Mix output is located far left, on a pair of male XLR connectors.Aux Inputs are located above the 8 inputs, on a pair of female XLR connectors. They´re hardwired Left and Right and are unity gain.External Power Supply connector is located on the bottom left corner.SIGNAL FLOW AND BLOCK DIAGRAM (Dsubs omitted for clarity)ON SLOT TECHNOLOGY ( OST TM )The MCM-8 II is also a 500 Series enclosure in a 4U Rack format, able to accommodate up to 8 modules. As the rest of the Heritage Audio line of 500 Series enclosures, it features “ON SLOT” Technology (OST).“ON SLOT TECHNOLOGY” takes advantage of last generation power electronics to handle power supply on a “per slot” basis. Each slot has its own power supply linear regulation stages, therefore modules are isolated from the rest. They just share the metal enclosure.With literally hundreds of brands making 500 series modules, we at Heritage Audio think this is the professional way of handling this reliably, eliminating issues often associated with sharing power between different modules of different brands and natures.Each slot features test LEDs for checking correct power operation (red for +16v, green for -16v), located aside of the slot connector.Thanks to the use of OST, the power capability of the OST-10 is 400mA per rail per slot maximum, with an overall of 1.4A (1.6A non continuous) per rail, whichever is reached first.SUMMING MIXER DESCRIPTIONThe MCM-8 features a passive voltage summing topology, similar to that found in the vintage Rupert Neve era discrete consoles.Passive voltage mixing requires its gain loss to be restored back to line level. Again, following the vintage topology, a stereo transformer coupled class A output amplifier is employed for this task. This amplifier is the same one used in the 73 module.The stereo Master Fader is placed PRE output stage, so driving it to saturation is possible.

Kii Audio The Egg 高端音响系统说明书

The Egg“The traditional wooden box has been replaced by a scientifically proven, curved enclosure that virtually eliminatesdiffraction and resonant effects”The Egg is a fully ‘Active Integrated Monitoring System’ that incorporates a fundamental rethink of the loudspeaker engineering process. The traditional wooden box has been replaced by a scientifically proven, curved enclosure that virtually eliminates diffraction and resonant effects that distort and smear the original sound. The result is a stunning clarity that brings the smallest details into focus and yet delivers the entire mix as a coherent whole.The system is complete, with a free standing control unit that delivers a perfect power match to the egg drive units, source select inputs, active analogue crossovers, LF and HF trim pot equalisation for room and location set-up compensation and a mid-band control to emulate the mid-range response of both Hi-Fi and NS10 type speakers. Above all, the Egg is designed to deliver the highest quality sound with the absolute minimum of coloration. In one word - Truth.“The ‘gimmick’ was mercilessly andprecisely engineered out of thisproduct quite a long time ago”Paul Mac – Audio Media December 2011• Unique monocoque shell construction rigid and resonant neutral•Near zero diffraction interference - smooth frequency response•No internal standing waves - greatly reduced smearing• Perfect bass port integration - superb transient response•Free standing control unit and integrated amplification with 3m matched speaker cables•Dual input switching and level control•Ultra fast and low distortion - 4*50W with 100W/Channel headroom indicator•Precise ‘sweet spot’ – unique LED locator guide beams• Integrated base with adjustable vertical alignment - allows for perfect sweet spot in both vertical and horizontal planes •Precision trim pots for bass (LF) and High Frequency (HF) calibration• Critical Mid Frequency equalisation for ‘Hard’, ‘Soft’ or ‘Reference’ (0) listeningKey Features“A truly unique product in a “me-too” marketplace”Frank Wells – PSN December 2011“Above all the Egg is designed to deliver the highest quality sound with the absolute minimum of coloration. In a word- Truth.”“Bi-amplification further enhances thepower headroom and results in thelowest possible distortion values”“They defy their size, and their price, andthey definitely defied my expectations.Neutral, clear, accurate – pretty much sums it up.”Frequency Response is the most common way to show the performance of a loudspeaker. This plot shows the on axis 1/3 Octave response of the Egg150 at a distance of 500mm with no modification or manipulation. The -6dB points are at 40Hz and 22kHz and each can be adjusted to suit individual rooms and taste. This plot is a high resolution (1dB/div) measurement of the bass port and driver at a point equidistant between the two from 50Hz to 500Hz. It shows perfect summing between the two with absolutely no phase or amplitudedistortion. This accounts for the absolutely stunning transient response of the Egg.“A monitor that flatters to deceive has no place in a professional recording studio and there is no argument for using poor quality speakers to match inferior playback media”“A beautifully simple and attractive idea”“The bass response is extraordinary”Hugh Robjohns – SOS January 2012“Brilliant.”Paul Mac – Audio Media December 2011• System Stereo Two way active control unit with four 50WRMS power amplifiers with dual linear power supplies•High Headroom capacitors and voltage rails • Bass reflex speakers with 50Hz QB4 front port alignment• Speaker effective internal volume 14 Litres• 2 way asymmetrical electronic crossover with nominal 2kHz alignment• 25mm HF unit sensitivity 95dB SPL for 1W at 1m•165mm LF sensitivity 89dB for 1W at 1m • 118dB Peak SPL at 1KHz both channels driven• Thermal tweeter protection with automatic cut out and reset•Input sensitivity Main +4/-10 dBu, Aux -10dBu • Continuously variable dual monitor level controls with switchable inputs• Frequency Response 45Hz to 20KHz (-3dB points)• Low Frequency Room Calibration +0/-10dB at 63 Hz continuously variable• High Frequency Calibration +1/-5dB at 10kHz continuously variable• Mid Frequency Adjustment +/- 1.5dB at 2kHz Centre Frequency 6 Internal Fuses:•35v power rails T5A (4 required)• 15v power rails we change to T1A (2 required) External Fuse:•Fuse for EU is 250v T2A • Fuse for USA is 250v T4A Technical Specification“There is absolutely no doubt that these are very good monitor speakers indeed… the Egg 150 monitoring system stands direct comparison with its peers extremely well and might even embarrass some!”Hugh Robjohns – SOS January 2012“The stereo imaging (is) very precise and completely stable, with a strong centre image and a superb impression of depth as well as spaciousness”“The Eggs might even cause other manufacturers to rethink their pricing. I’m certain you’d have to go a way up the cost scale to find comparable quality.”“We can run through all the typical adjectives—smooth, flat, dynamic, even, with superlatives given on all counts including imaging and depth—but in the final analysis, the music played through the Eggs just sounds as it should”“An emotional experience.”Hugh Robjohns – SOS Jan 2012Frank Wells – PSN Dec 2011Paul Mac – Audio Media Dec 2011Music。

AR824数字式噪音计

AR824数字式噪音计
一、产品介绍:
声级计又叫(噪音计)是噪声测量中最基本的仪器。

声级计一般由电容式传声器、前置放大器、衰减器、放大器、频率计权网络以及有效值指示表头等组成。

声级计的工作原理是:由传声器将声音转换成电信号,再由前置放大器变换阻抗,使传声器与衰减器匹配。

放大器将输出信号加到计权网络,对信号进行频率计权(或外接滤波器),然后再经衰减器及放大器将信号放大到一定的幅值,最后经过数字电路处理器处理后,在LCD上显示相应的数值。

概述
对于创造性产品决不能妥协,相信HR824是世界 上最精确的近场监听箱之一。 若你不使用精准的有源监听箱,你就会浪费掉 花费在其它设备上的费用。试想一下,监听音箱是 录音及混音链中唯一可听到的:所有贵重的话筒, 优秀的信号处理器,(以及调音台),只有通过你 的监听音箱才能到达你的耳朵,如果监听箱出了问 题,你就会遇到很大的麻烦。 当他们听了HR824后彻底改变了看法:宽广的立 体声声场,深度感,不可思议的细节,干净、清晰 的高中音再现;如此小尺寸的音箱却有着令人惊异 的低频扩展,既不过度夸张也不会遗漏任何细节, 你能分辨到的是每一件低音乐器而不仅仅是普通低 音的加重。最重要的是:"SWEET-SPOT"--声场内的 最佳听音区--不只是一点,而是更宽的三维空间, 不论站立或坐下时都会听到相同的效果,你与其他 人同时精准地听到调音效果。 三年后的今天,HR824已成为监听领域内的参考 标准。世界上一些顶级工程师及音乐制作人都在使 用它们,事实上它们已经遍布几千个主要的录音室。 拉斯维加斯顶级主流录音室靠它们来控制最终录音 品质:"HR824是唯一表现出细微细节的监听箱",MIX 杂志把HR824送到独立实验室,他们认为是所有检测 过的"最精确的近场监听箱"很多工程师事实上随身 携带他们的HR824,以保证他们在不同录音室的听感 精准度。为此,我们还专门设计了便携包。 HR824如此精确的原因是有源设计,严谨的、正 确的有源设计。下面是它的一些背景资料。
