Control Surface2. DSP Core3. IO4. Monitoring & Signalling5. External Synchronisation2.1 System Block Diagram2.1.1 Block Diagram showing system utlising D21m IO SystemGlobal Wiring Overview Vista 8 (with D21m I/O)Vista 8 Desk (with built-in Control System)TB Int D21m StageboxStagebox IO(Option: Mastersync Unit)PLEASE NOTE: This is a general System Block Diagram. Actual number of D21 IO frames will depend on customer requirements.2.2 Control Surface (Vista 8)The Control Surface of the Vista 8 is shown below (only 1 fader bay shown):The control surface features the industry acclaimed Vistonics User Interface which offers a “where you look is where you control” philosophy. The Studer developed Vistonics technology mounts rotary controls and switches on TFT Screens. This then offers the user the benefits of screen technology (Touchscreen, colour, icons and text) without the limitations of having to access physical controls away from the where the control is displayed. A touch and access philosophy combined with Channel strip orientated operation offers a friendly and intuitive operating concept.This extremely intuitive and fast to learn operational concept is further enhanced by 4 other key operational features that frees the users mind from working on the console and allows more thought to be placed on the work at hand. These key features are:• Momentary/Latching Activation of all ButtonsThe console recognizes and senses the button-push duration and responds accordingly. The buttons therefore act momentarily or latchingly depending on how they were pressed (pressed-and-held or briefly tapped). In addition to Talkback, PFL, EQ on/off, etc., the functions affected include those accessed by the touch-screen - such as viewing of audio function - as well as the monitoring source selectors and the machine control.• GangingThe ganging function in the mixer allows the operator to quickly apply functions to multiple channel strips because channels within the gang act as one. This can be used, for example, for Mute, Automation mode changes, faders, Bus assign and much more to increase speed and comfort in operation. Creating a gang over the console makes the set-up quick and easy.• Fast Copy/Paste and Half-Lit KeysThe console incorporates dedicated copy/paste keys for each audio function including EQ, dynamics, panorama and delay. A simple button-press in the original channel and another in the target channel copies the settings across. Copy/Paste is guided up by the half-lit buttons: if one button has been pressed and the desk is awaiting a second button-press, all available target buttons illuminate at half brightness until one of them has been selected. Also, complete channels can be cloned to one or many target channels. Setting up the Studer Vista 7 for a production becomes a quick and easy task. Non-productive time is reduced considerably.• Banking with Scrolling NavigationDSP channels not visible on the physical desk are accessed by scrolling the channels available in the DSP core. The channel order is freely assignable: channels can be grouped or even shown repeatedly on the surface. This ensures physical orientation on the desk so that the operator is always clearly informed as to what is happening. Channel Bays with, for example, the master channels can also be locked in place.The Vista 8 also includes a completely redesigned Control Bay. While talkback and monitoring functionality, trackball and a motorized joystick have been maintained from the previous Vista consoles, dedicated control elements have been introduced for operation of outputs. 12 motorizedfaders and a Vistonics™ screen with 40 rotaries have been added. Multiple user definable assignments of these 12 faders and Vistonics™ controls are possible to be recalled by one button press, giving up to 52 directly accessible level controls for controlling all sorts of outputs such as master, groups or matrix outputs. Two of the faders will act as “grand masters” without alternate pages, allowing instant influence on all console outputs if needed. The other 10 fader strips as well as all 40 rotaries with their pushbuttons will allow also SOLO/PFL, MUTE as well as TALKING to each masters individually. Metering has also been extended: 40 meters are visible on the Vistonics and the corresponding level controls are immediately available on the rotary controls next to them. Looking at levels and correcting them therefore is just a fraction of a second away.Another major improvement is the “reverse operation” of masters and their busses. Vista 8 can show all channels contributing to a specific master bus on the Vistonics™ screen and allows level adjustment of all those channels instantly - without physically accessing the contributing channels themselves on the fader bay.Furthermore the control group functionality (VCA style) will be extended to form control groups with different levels of control (hierarchical control groups). Each channel strip allows the possibility to flip a single fader to a second layer without flipping the whole console. Dynamic Automation is also a feature of the desk. You can boot the desk in one of two modes; Snapshot automation for live on-air or dynamic automation for production use. New dual colour metering is provided on each channel to give better headroom indication which is definable.2.3 DSP CoreThe DSP core of the Studer Vista 8 builds on Studer‘s well-proven digital technology. It incorporates an excellent reliability record and inspires a high degree of confidence enjoyed by the numerous users operating systems in mission-critical applications. The DSP core uses parallel processing architecture with integrated floating point circuitry and an internal word length of 40 bits. No overloads will ever occur within the console, since floating point architecture is even used in the summing busses. The system can be used in 48 kHz or 96 kHz mode.The DSP Core is based on modular cards and the more DSP cards that have been fitted in the core, the more DSP power is available. DSP Boards can have 8 AES IO incorporated per board.An offline Configuration Editor tool is also available which allows the available DSP Power to be reconfigured by the customer. This includes changing the number of channels, audio processing and bussing structure of the console for a particular project. Extensive import functions allows the user to adapt existing configurations to meet changing needs. In addition, the combination of modular DSP cards and the configuration editor means that future console expansion is as simple as adding more DSP cards and making new larger configurations with the configuration editor.2.4 Input/Output SystemThe D21m high-density audio interface system is like a hub to the Vista 8 DSP Core. The 19” Frame can hold up to 12 interface cards where audio is collected from or distributed to all standard professional industry audio formats.Up to 384 inputs and outputs from 12 audio card slots are collected in the center of the 3U D21m Frame where one or two High Density Cards can be placed. These cards provide the link to the DSP Core of the console using standard CAT 5 cable connections. Each connection carries up to 96 channels into the Performa DSP Core and 48 channels out in 24 bit 96Khz quality. The system automatically detects newly inserted cards and assigns the appropriate number of Input/Output channels to it. A status display on the front panel informs the user if a card is present or if the card has failed or been removed. The Frame may also be ordered with redundant power supplies. In addition, all D21m audio cards are hot-pluggable.2.4.1 Available D21m Audio IO Cards• Microphone Card: 4 x microphone Preamp with 24 bit Converter (split output available as standard)• AES/EBU Card: 8 x AES/EBU in and 8 x AES/EBU Out• AES/EBU Card with Input and Output SFC: Same as above but with asynchronous sampling Frequency converters on both inputs and outputs.• Line In Card: 8 channel D/A Converter Board (Specs?)• Line Out Card: 8 channel A/D Converter Board (Specs?)• ADAT Card: 2 optical input and 2 optical output interfaces• TDIF Board: 2 TDIF Interfaces• MADI IO Board: 1 x 56 or 64 channel MADI Input and Output. A Second input and output is available and can be used as a redundant MADI or to provide a split MADI signal of Output 1.2.4.2 D21m Stagebox SystemThe D21m Stagebox system utilises a D21m Hub which sits local (10m) to the DSP Core and stageboxes which collect all the remote IO signals and convert them to a single 56 or 64 channel MADI signal. The Hub then receives the MADI signals from the stageboxes and sends them to the DSP core via a single CAT 5 cable. The hub can handle up to a maximum of 6 stageboxes. A D21m Hub can also handle any of the local IO. Any stageboxes with Microphone Preamp cards will require some control data from the Vista Control Surface. This control data is first sent to the D21m Hub where the control data is merged with the MADI stream. The system can automatically detect stageboxes with microphones and send the correct Control Data from the desk making operational handling incredibly simple. This auto detection mechanism means that sharing stageboxes between different Consoles is extremely easy requiring no user administration.2.5 Monitoring, Talkback and SignallingA single 3U rack unit is utilised for housing all of the Monitoring and Signaling cards of the system.2.5.1 MonitoringThe monitoring is controlled in the analogue domain. Some fixed AES/EBU outputs are utilized from the Vista 8 DSP Core and are fed to converters built into the monitoring frame. 5.1 monitoring is standard on the Vista 8 with Dolby EX Monitoring as an option. The Control Room monitoring section on the control surface provides control of up to three different speaker systems (Two multi-channel and one stereo) and 76 source selectors. All internal digital sources can be assigned to any of the source selector keys as mono, stereo or multichannel sources. The 2 Studio Monitors are configurable in the same way as the CR Monitor section, although as standard only stereo studio loudspeaker feeds are supported. Surround studio feeds are available with a custom monitoring frame.A headphone socket is also available on the control surface for use in the control room.2.5.2 Talkback and SignallingAn extensive talkback system is implemented within the Vista. The talkback source can either be the built in desk operator microphone or an external producer microphone. Several destinations, such as buses, direct outs, auxillaries, groups and master outputs are available on block. The block diagram below shows the talkback and signaling possibilities of the Vista 8.Talkback and signaling blockdiagram2.6 External SynchronisationExternal digital synchronization of the console is provided by a Studer Mastersync Unit. This single 19 inch 1U unit will allow the console to be synchronized to an external video black burst, wordclock or AES signal.A second mastersync unit may be used as a redundant unit with an automatic switchover should a problem occur with the first unit.3 Troubleshooting3.1 System SurveyorThe software graphical controller has a built in real/time system surveyor. This surveyor monitors the status of all of the communication between the various parts of the system and provides a visual indication to the user of the status. This is extremely re-assuring for the user who not only has a continuous visual performance indication, but if there is a problem, clicking on the icon will show the user where problems have occurred. See the screenshot of the surveyor window below. It also surveys all of the IO racks and displays the status of each individual IO Card and Power supply in the D21m Frames.This is also extremely useful for service issues. A log file is also kept which logs any system errors. In some instances, this can then be sent to the factory (via e-mail) for fault finding assistance.3.2 Service IssuesAs far as the control surface is concerned, each bay is a single module which opens up like a car bonnet to access inside the console (See picture). All cable connections to the control surface are on the front of the console for easy access.The DSP, IO and monitoring are all made up of have modular cards.4 RedundancyThere are 5 areas where redundancy is available:Power suppliesDSP CoreMADI LinksComplete Control SystemControl SurfaceMastersync Unit4.1.1 Power SuppliesWithout exception, throughout all parts of the system redundant power supplies that automatically switch in case of failure of the primary supply are provided. This includes: Control SurfaceDSP CoreMonitoringAll I/O FramesControl System (Installed as standard)4.1.2 DSP CoreThe DSP Core is the audio heart of any Digital Mixing Console and therefore if a problem is to occur in this part of the system, it will usually result in some audible problems. It is therefore essential that some redundancy is available to ensure continuous and seemless audio even in the event of failure of part of the DSP Core.The Studer Vista 8 DSP core is based on mature technology with over 250 broadcast consoles worldwide utilising the DSP core in round the clock use. The design of the Vista 8 DSP Core provides seemless audio flow with no disruption to the operator in the case of a DSP Card failure. Both the physical design and DSP architecture mean that, assuming a redundant card is available in the DSP Core, the redundant card will instantly take the role of a failed card with a worse case scenario of a small mute in audio. A failed card may then be physically replaced with a new card in a hot pluggable manner, again once installed assuming the role of a redundant card. The replaced DSP card is auto detected in the system with no need for reboot of any part of the system. If a DSP card is to fail, the worst case scenario in terms of audio is a small mute (less than 1 sec) and the operator is simply informed of the failure by a pop up window in the Graphic Controller. In terms of operation, the user is not affected and can continue undisturbed.The amount of redundancy is dependent on the number of ‘idle’ cards that are available in the DSP core and this in turn is dependent on the configuration1 that is currently loaded. If two DSP cards lay idle, then this gives the possibility for two cards to fail without interruption.It should be mentioned that if a DSP Card with AES inputs and outputs fails, the processing will automatically switch but the 8 AES IO for that card, however will still be hardwired to the failed card. This would mean the loss of the IO signals which were connected to the failed card although the DSP processing will still swap to the redundant card.It should also be noted, the DSP Core configuration is stored within the DSP Core itself. This means that in the rare event of a problem with the Control System, audio will pass through the DSP Core. In fact, the control system need not be running at all for audio to pass through the DSP Core. The other advantage of this is that audio passes through the DSP Core in a matter of seconds from DSP Core Power up.4.1.3 MADI LinksEvery IO frame with a MADI Link can have a second redundant MADI link which would switch automatically if an invalid MADI signal is received.4.1.4 Control SystemThe Control System is central to the communication and control of the different parts of the system. For this reason, redundant Power Supplies and Raid 0 removable hard drives are fitted as standard.A second, fully equipped Control System housed underneath the console is available as an option offering full 100 % redundancy and peace of mind. The user has the ability to switch to the redundant Control System for emergency reasons. The data is backed up with an adjustable time interval and automatically accessed by the redundant System when the emergency switch is activated. Both Systems can be accessed from the same keyboard. It is possible to switch GC screen and keyboard/trackball easily back and forth between both Control Systems. If the emergency switch is activated, the keyboard/trackball/GC is automatically switched to redundant Control Systems as well. The emergency switch is located in the meterbridge and must be pressed several seconds in order to activate the emergency switch. After switching, the user must boot the application from the redundant PC before he has control. This takes approx 20 seconds. Both Control Systems may be switched on and off separately, but are normally linked together by a jumper, located within the meterbridge.4.1.5 Control SurfaceThe Control Surface is made up of a number of modular Fader bays. Should one of these bays fail, all other bays will continue as normal. The concept of navigation allows totally free allocation of DSP Channels to physical channel strips. In this instance, the user can quickly and easily re-arrange the strip layout in the Graphical Controller of the control system to re-assign the channels that were represented on the failed bay. In addition, the navigation philosophy allows scrolling of the virtual desk in front of the user. This also provides very fast navigation in such events.4.1.6 Mastersync UnitThe Mastersync unit provides the clock reference for all parts of the system. The unit can either synchronise to an external clock or generate it’s own clock. The unit can have two separate and different clock sources connected to it and will automatically switch to the redundant input should there be a problem with the primary clock source.A complete standby mastersync unit is available as an option that will instantly take over should the main unit have a failure.4.2 N-1 DescriptionThe N-1 System for the Vista 8 is based on a bussing system. Any number of N-1 busses can be configured which means that each outside source or telephone hybrid can be assigned to be the owner of one bus. Any channel on the console can be routed to these n-1 busses (except the owner to the relevant bus) and assignment is typically pre setup. By using the quick bus assign functionality, a channel can be quickly de-assigned from a particular bus. All control of overall level, N-1 On/Off and talkback are provided on the channel itself. In addition it is possible to adjust the send level of a particular source to all of the n-1 busses. This is particularly useful for 2 track sources which the outside source wants to hear but at a lower level. In addition, a bus owner splits its’ input meter for the left hand side of the meter to show the return level and the right hand side of the meter the N-1 Send.One further feature of the N-1 system is the ability to send the outside source an off-air signal whilst waiting to go live. This is achieved by the simple activation of the ‘Alt N-1’ button on the relevant N-1 owner channel. When the operator opens the fader of the outside source, the appropriate N-1 bus output is then automatically sent to the outside source without the user having to manually de-select the off-air signal.An off-air conferencing (MPX) function is also available allowing any number of outside sources to talk together whilst off air. When one of the outside sources is put on-air, they are automatically removed from the conference and fed their correct N-1 bus without operator intervention.5 Technical Specs5.1 Vista 8 Control Surface Dimensions5.2 Power ConsumptionApproximate figuresControl Surface:150W for Control System and Control Bay. 60 Watts in addition per fader bay. Example: 40 faders (3 fader bays and 1 Control Bay) = 150 + (3x60) = 330W DSP Core:20 Processing cards = 800 WattsMonitoring Frame = 100 WattsD21m IO Frames = 150W per frame。

调音台说明书-------------------------------------------------------------------------------- 一个简单而又完整的音响系统，从开始到结束起码包括了话筒、调音台、功放、音箱四个单元。

当然，调音师实际使用的音响系统要比此复杂得多，在多路信号输入的时候，除了话筒，还会有DVD 影碟机（或者CD机）、录放音卡座、MD卡座等。

此外，还会用到专业声频处理设备如混响器、延时器、激励器、压限器、扩展器、均衡器、分频器等。

但是，从整个工作流程来看，调音台无疑位于关键和枢纽的位置，起着承上启下的作用，因而调音师的调节便起着至为重要的作用。

一调音台的功能在使用调音台之前，对于调音台的功能我们要有充分的了解。

调音台是专业音响系统中最重要的设备，一套专业音响系统往往是以调音台为核心的。

常用的调音台能同时接受8~24路不同的信号，并分别对这些信号在音色和幅度上进行调整加工处理。

一般来说，调音台有四个主要功能。

第一个功能是对节目信号进行放大。

当各种不同节目源的信号进入调音台后，其不同的信号所需的放大量也不尽相同，所以调音台必须能分别处理不同的信号。

如各种乐器的音乐信号与人声信号在幅度上就不相同，当然就需要分别进行处理。

第二个功能是分别对各种信号进行频率调整（即调音）。

我们知道，不同的信号，由于其频谱分布，谐波成分等方面的原因，形成不同的音色，而建筑物对声音的影响使音色产生很大的变化。

音响师要根据不同的扩音环境，对进入调音台的不同声音信号分别进行加工，使其声音尽可能接近原声。

调音台的每个声道都具有相同的处理手段，如：3段均衡、增益控制器、高通滤波器等。

第三个功能是信号的合并。

调音台将各路信号调整后，要将各种信号合并成标准的左右声道（立体声）形式输出，作为下一级设备的输入信号使用，这是最基本的功能。

第四个功能是分配功能。

调音台除了立体声的主输出外，还能提供两路以上的辅助输出信号，这类信号有两种用途，一是音响室监听或舞台返听；二是做效果器的激励信号用。

八路调音台使用图解八路调音台主要结构：当最初接触调音台的时候，很容易会被它面板上花花绿绿、数目众多的旋钮和推杆唬住。

首先我们来看一下左边的面板。

实际上，左边每一路的推杆和旋钮的意义都是一样的。

所以你只需要集中精力了解一个通道的操作方法就可以通盘掌握。

较少路数的调音台有4路和8路的输入控制，而路数最多的有96路甚至更多的。

这个调音台有8路输入控制，我们只取其中一个来讲解各部分的作用。

1.MIC：麦克风输入接口麦克风输入经由XLR 母座，可接受平衡式或非平衡式低电平讯号，使用专业动圈式、电容式或丝带式低阻抗麦克风，如果使用非平衡式麦克风需要尽量使用愈短愈好的麦克风线，以避免电波噪音的干扰。

2.LINE：高电平输入接口高电平输入通常经由 TRS 1/4" 立体 Phone Jack 或 TRS 1/4" Mono Phone Jack 送入，麦克风音源以外的讯号都可经由高电平输入至混音机，立体 Phone Jack 的输入是平衡式的，相同于 XLR 的方式，但是如果一定要用非平衡式器材时，可用 Mono Phone Jack ，其接线不能太长（4.5m 以内）。

3.LINE -20DB：衰减 20 分贝按键按下此键可以对输入电平衰减 20 分贝。

一般在环境噪音较大，设备电平噪音较大或电平过高的时候使用该按键。

使用该键将对音频输入信号的所有频率进行衰减，以达到将音量较小的杂音或电噪音过滤掉的目的。

有时会出现输入电平信号过高的现象，如不进行衰减，则衰减器的控制范围就会大大降低，只能在一个很小的区域内滑动，造成对音量输出控制很难操作。

此时应按下此键，以增大衰减器的有效控制范围。

4.PEAK：峰值指示灯Peak 灯亮时，警告使用者输入信道内的讯号过强。

发现 Peak 灯亮时，并且任由这种情况持续的话，调音台会启动自我保护功能，切断音源输出。

所以，此时应调整输入音量大小，否则，调音台的音频输出将被自动切断。

调音台又称调音控制台，它将多路输入信号进行放大、混合、分配、音质修饰和音响效果加工，是现代电台广播、舞台扩音、音响节目制作等系统中进行播送和录制节目的重要设备。

调音台按信号出来方式可分为：模拟式调音台和数字式调音台。

调音台种类调音台在输入通道数方面、面版功能键的数量方面以及输出指示等方面都存在差异，其实，掌握使用调音台，要总体上去考察它，通过实际操作和连接，自然熟能生巧。

调音台分为三大部分：输入部分、母线部分、输出部分。

母线部分把输入部分和输出部分联系起来，构成了整个调音台。

根据使用目的和使用场合的不同，调音台分为以下几种：（1）立体声现场制作调音台（Stereo Field Production Console）（2）录音调音台（Recording Console）（3）音乐调音台（Music Console）（4）数字选通调音台(Digital Routing Mixing Console)（5）带功放的调音台(Powered Mixer)（6）无线广播调音台(On Air Console)（7）剧场调音台(Theatre Console)（8）扩声调音台(P.A. Console)（9）有线广播调音台(Wired Broadcast Mixer)（10）便携式调音台(Compact Mixer)调音台作用（一）调音台输入部分的插座、功能键①卡侬插座MIC：此即话筒插座，其上有三个插孔，分别标有1，2，3。

标号1为接地（GND），与机器机壳相连，把机壳作为0伏电平。

标号2为热端（Hot）或称高端（Hi），它是传送信号的其中一端。

标号3为冷端（Cold）或称低端（Low），它作为传输信号的另一端。

由于2和3相对1的阻抗相同，并且从输入端看去，阻抗低，所以，称为低阻抗平衡输入插孔。

它的抗干扰性强，噪声低，一般用于有线话筒的连接。

②线路输入端（Line）：它是一种1/4"大三芯插座，采用1/4"大三芯插头（TRS），尖端（Tip）、环（Ring）、套筒（Sleeve），作为平衡信号的输入。

调音台使用方法与接口认识提到音响系统，我们当然首先会想到调音台，调音台，会有很多种形容法，最贴切的莫过于把调音台比喻成一个音响系统的心脏了，这个心脏血液循环的如何，直接影响到整个系统的性能。

形象来说调音台就像一个大的水处理池，我们把多种音源信号像流水一样输入进这个大水池，然后在水池内对流入的各种水进行合理的处理，最后再从各种不同渠道流出去，整个过程就是这么简单。

因此对调音台的连接无非也是：输入和输出两大部分。

（一）、调音台输入部分的线路连接：调音台的输入信号大体上分为低阻话筒信号输入和高阻线路信号输入两种。

其实我们可以把低阻和高阻的区分看成是水压力或水流速度的不同。

比如：高阻输入的电平高，就好像水压很大，水流较急，直接输入到调音台这个水池里就合适了，不用在中间加什么环节来调整水压和水流速了；但低阻输入的电平低，就好像水压很低，水流很慢，直接输入到调音台这个水池里就不合适，我们就需要在大水池里加上一台抽水机，把低阻的低水压给它加大，让水流速度加快！所以调音台的低阻输入通道线路里都内置了专门的电路放大器，把低电平放大到合适的电平。

这样用水的特点来形容低阻信号和高阻信号大家应该很好理解了。

1、MIC NE（麦克风/线性输入）——可连接低噪音麦克风前置放大器或线路电平输入的组合式输入接口。

2、GAIN（增益控制）——用于控制麦克风或线性输入的电平。

3、CLIP（过载提示）——当输入增益调得过大时并过载时，红色LED 将亮起。

4、HIGH FREQUENCY（高频调整）——控制通道均衡器的高频波段。

（在12KHz上的+/-15dB范围内）5、MID FREQUENCY（中频调整）——控制通道均衡器的中频波段。

（在2.5KHz上的+/-15dB范围内）6、LOW FREQUENCY（低频调整）——控制通道均衡器的低频波段。

（在80Hz上的+/-15dB范围内）7、LOW CUT（低切）——80Hz低频衰减开关，用于消除低频段的噪声。

1. 打开调音台电源，插入耳机或音箱等设备。

2. 调整音量，使用主输出音量控制和输出选择按钮，选择要发送到哪个信号处理器或音箱。

3. 调整输入通道增益：选择一个输入通道，将增益旋钮旋转到适当的位置，以确保声音不失真。

4. 调整EQ：使用频率调节和切割控制来过滤音频信号，以调整音频质量。

5. 添加效果：使用内置效果器，如混响和压缩器等，增加音频效果和可听性。

6. 监听/录制：使用耳机或扬声器监视混音输出，并记录混音输出到录音设备上。

7. 调整平衡和pan：使用pan控件调整声音在左右扬声器之间的平衡。

8. 存储预设：调整混音后，可以将它们存储为预设，以便以后快速回调。
