11.FADER：衰减器(音量推子)
决定该通道信号发送给总线输出的音量大小。
音量推子实际上是一个衰减器，用于对该通道的输出信号进行衰减。
当推子位
于最下端（或音量旋钮位于最左端）时，信号被无穷衰减。
这时，该通道没有信号输出。
调节范围－∞ ～＋6 分贝，一般
以推到0 处适宜，超过0 则会使声音产生一定程度的失真。
如果一定要提高电平讯号，一般采用适当提高Gain的办法，而
不会将衰减器提升超过0 。
由于音乐输入为连续，而人声输入为间断，故在操作上有一定区别。
在对音乐的输入轨道操作时，一般使用“淡入”、“淡出”效
果。
即操作时先缓缓推拉衰减器，再慢慢加快操作速度，切忌匀速推拉或者瞬间大幅度的操作，这样会使听众感觉很不舒服。
而在对人声输入通道进行操作时，一般采用“一步到位”操作。
即在需要人声的时候，将推子一下推到大概合适的位置，再根
据监听和电平表显示进行细微调节。
而不需要人声时，要马上把推子拉到最底部，以避免不必要的声音被输入进去。
接下来，我们再看看调音台右面的控制面板。
之前左面的面板是用来调节输入信号的，而右面的则主要负责调节输出信号。
ART MX821八路混音器音频路由器操作手册说明书
ART – MX821Eight Channel Mic/Line Mixer with Tone ControlOPERATION MANUALINTRODUCTIONThe MX821 is a versatile rack mount mixer combining eight independent input channels into a single mono line level mixed output.Essential features include: XLR microphone and 1/4 inch line level inputs, Level and Tone controls, and switch-selectable +48 Volt phantom power on each channel. Main output is balanced low impedance. Additional Pre-Fade output and Aux Buss input jacks allow patching of multiple MX821’s when more channels are needed.Built in power supply and single high 19-inch rack mount format allows for easy installation and reliable long-term operation.FEATURES:•Eight Independent Input Channels•Level and Tone Controls on each Channel•Balanced XLR Microphone and 1/4-inch Unbalanced Line Inputs on each Channel•Full +48 Volt Phantom Power on XLR inputs with DIP Switch for each Channel•Balanced TRS 1/4-inch Main Output Jack with Master Level Control•RCA-type Pre-Fade Output Jack (Not Affected by the Master Level Control)•RCA-type Aux Buss Input Jack for Channel Expansion•Solid Single High Rack Mount Chassis w/ Built In Power SupplySPECIFICATIONS:•Input Connections: XLR-F balanced (8), 1/4-inch unbalanced (8), RCA (1)•Output Connections: 1/4-inch balanced TRS (1), RCA (1)•Input Impedance: 2K Ohms Mic, 20K Ohms Line, 10K Ohms Aux.

(2.9kg)OPERATIONa) Verify proper voltage selection on the IEC style power connector for your location. Connect the AC cord to a grounded AC outlet.b) Connect low-impedance microphones to the XLR sockets.c) Connect shielded unbalanced line inputs to the ¼” inch jacks.d) For microphone channels requiring phantom power (for condenser microphones) set the appropriate PHANTOM POWER DIP switches in the down position. Do not engage phantom power on a channel unless it is for a condenser microphone.e) Switch on the power and set the MASTER LEVEL to the ½ way setting, then adjust the channel LEVEL controls as required for the best mix and level. Adjust the channel TONE controls for the desired balance of lows and highs. Center setting is neutral.f) Re-adjust the MASTER LEVEL as required for best overall signal level.g) To patch two MX821’s for 16 channel input operation, run a shielded, unbalanced RCA type patch cable from the PREFADE OUT jack on mixer A to the AUX BUS INPUT jack on mixer B. Note that only the MASTER LEVEL on mixer B will now function.h) To convert the ¼” line input on any channel to a direct line output for that channel, unplug the MX821’s AC cord from the wall and remove the top cover. Inside you will see a row of jumpers. Move the jumper for the desired channel to the left, when viewed from the front. Now that channel’s line input is converted to a direct line output and may be connected to the input of another mixer. Any converted channel is still included in the main output mix as well. Do not connect the output of a mixer or any other signal source to the ¼” jack on this channel now or the channel may sustain damage. Be sure to replace the lid before plugging the unit back into the AC socket.WARNINGSAll operating instructions should be read before using this equipment.To prevent the risk of electrical shock, do not remove the cover.There are no user-serviceable parts inside.

★平衡八通道麦克风或线路输入，每路声道优先权可分别设置在优先设定声道发言时（供会议主持者），其它声道输入电平信号将自动关闭，多个通道同时设定优先时则按顺序发言，即“一个接一个”。
另设一路辅助线路输入，可以会议间隙插放背景音乐。
间隔时间可通过电脑设定。
★一路麦克风平衡输出，可连入调音台、功放等系统设备，一路辅助线路输出，可连入录音设备，进行会议记录。
★为配合宽频段电容麦克风使用，提供48V幻像供电。
★具备Control Voltage输出端子，可控摄像机、指示灯等应用器材的开关。
★自动混音功能切换手动模式，可令其作一般混音器使用。
★TS-8M可通过RS485端口转由电脑来进行控制和设定，附有简洁方便的操作界面，可实现主持话筒优先后，列席话筒亦可设置为顺序发言模式，即由一般混音器的二级模式升级为三级模式。
四种应用模式：一、 主持发言模式〈1〉单台使用其中任一路话筒选定在“DOWN（下）”位置，其余话筒设置在“UP（上）”位置时，设置在“DOWN（下）”位置话筒将有优先权的主席功能，其讲话同时，其余声道被切断，其它声道发言时，主持位话筒可予以打断。
〈2〉多台串接使用其中任一路话筒选定在“DOWN（下）”位置，其余话筒设置在“UP（上）”位置时，设置在“DOWN（下）”位置话筒将有优先权的主席功能，其讲话同时，其余声道被切断，其它声道发言时，主持位话筒可予以打断。
一般在第一台混音器作此设置。
二、顺序发言模式所有声道拔至“DOWN（下）”位置，同一时间内，只能允许一路处于发言状态，智能混音器的锁闭线路“Lockout”功能启动，直到当前发言人出现停顿后，锁闭功能自动解除，其它某个发言通道则可进入发言状态。
即一个接一个的发言。
Priority Pre-select1 2 3 4 5 6 7 8(图1-1)Priority Pre-select(图2)Priority Pre-select1 2 3 4 5 6 7 8(图1-2)三、自由发言模式所有声道拔至“UP（上）”位，锁闭功能失效，所有声道可同时发言。
四、电脑控制模式（TS-8M）此种模式下，手动设置将失效，混音器模式设定功能由电脑完成，可设定主持话筒后，列席话筒可设置为顺序发言模式。
安装及调试步骤：1、按安装要求连接线路。
2、把“Master Threshold”顺时针旋转到底，预选开关“Priority Pre-select” 全部拔至下方，所有声道增益旋钮逆时针调至最小。
3、开启智能混音器电源开关，此时会看到各话筒通道的LED 灯顺序开启及关闭，自动进行检测。
4、任选一路，调整增益旋钮，使其刻度在九点钟位置，依正常讲话距离对话筒讲话，同时配合LED 指示，调试增益至合适的电平输出。
5、逆时针调校阀锁“Master Threshold”旋钮，逐渐减弱电平直至在正常讲话音量时，闭锁“Lockout”的LED 指示灯闪亮。
6、相继接上其他话筒，并如步骤4调整话筒电平增益至适当的电平输出，但不用再调整阀锁电平控制。
7、依据会议所需模式，拔动预选开关“Priority Pre-select”的左下方的隐蔽主电平控制“Master Level”为混音器的最后级电平调节，根据需要用螺丝批调节。
Priority Pre-select1 2 3 4 5 6 7 8(图3)8、关闭阀锁“Master Threshold”旋钮，阀锁功能关闭，此时智能混音器可作一般混音器使用。
9、多台联机时，Link连接以如下方式：以连接至调音台的这台混音器（A）为基准。

The orderly and high-class process control of conference could be easily achieved after the simple installation and setup. Furthermore, the large capacity built-in microprocessor the device adopts will ensure the process control proceed much more smoothly. Any number of mixers can be linked to create a system for large multi-mic installations due to its excellent extensibility.★ There are eight-channel Mic/Line balanced inputs with a pre-selected priority option for each channel in two versions: ‘the chairperson mode’ with one pre-selected channel prior to all others and ‘the one after another mode’ with a few priority channels working in a row.The Aux input is an RCA jack accepting auxiliary-level input used for broadcasting background music during the conference break set by computer.★ Mic/Line balanced output: connects with sound mixer and amplifier; Aux output: connects with recording equipment for conference tracking record.★ Powered by 48V Phantom Power Supply for adopting condenser microphone with wide frequency range★ Control Voltage Output: provides 0-+4VDC(active high) to trigger external devices such as camera switch and light indicator.★ Switchable manual mode overrides automatic functions turning the device to working like a conventional mixer.★ Possibility of being controlled and set up by computer through RS485 ports. Furthermore, the compact and convenient operating interface is available to help set a single mic to work on the prior channel as a chairperson, while setting the mode of speaking orderly for other mics left.Four Operating Mode ：二、 “The Chairperson”mode〈1〉Single MixerOnly one Priority Pre-select Switch is on “DOWN” position while theothers are all “UP”. The mic on “DOWN” position which is selected as priority can come on at any time and override any other mic that is “UP”. 〈2〉Multiple MixersOne of any Priority Pre-select Switch is on “DOWN” position while theothers are all “UP”. The mic on “DOWN” position which is selected as priority here can come on at any time and override any other mic that is “DOWN”. Usually this setting is operated on the first mixer.二、Orderly Speaking ModeAll Priority Pre-select switches are on “DOWN” position. In this mode only one mic at a time could be “on”. As soon as the first speaker pauses, the lockout bus goes inactive and any other mic can come on. This mode is known as “First-come-first-served”.Priority Pre-select(Figure1-1)Priority Pre-select(Figure2)Priority Pre-select1 2 3 4 5 6 7 8(Figure1-2)三、Free-Talk ModeAll Priority Pre-select switches are on “UP” position. The lockout will go in active in this mode and all mic could speak at the same time.四、Microprocessor Controlled Mode （TS-8M ）The manual setting will go inactive in this mode. All the operation modesare set by microprocessor: set a single mic to work on the prior channel as a chairperson, while setting the mode of speaking orderly for other mics left.Installation and Setup ：1. Connect as per setup instruction.2. Turn the“Master Threshold” clockwise to the minimum position; set all the “Priority Pre-select Switches” to “DOWN” position; turn all gain controls fully counterclockwise to the minimum position.3. Turn power switch “ON”. The mixer will perform a self-test and turn each microphone “ON” or “OFF” consecutively.4. Connect a microphone to a random Input and turn its Gain Control to the “nice o’clock” position. Adjust the Gain Control for proper output level according to the meter indication when speaks into microphone.5. Turn the “Master Threshold” counterclockwise to reduce the output level till it is on the position of speaking in a normal volume, then the “Lockout” LED will be lighting sustained.6. Plug in up to the rest microphones and adjust each respective Gain Control for proper output level as per the above mentioned Item 4. It should not be necessary to readjust the threshold level.Priority Pre-select1 2 3 4 5 6 7 8(Figure3)7. According to the requirement of the selected mode, the Master Levelrecessed control under the left side of “Priority Pre-selected Switches” maybe adjusted with a small screwdriver. This control is at the last stage in themixer.8. Turn off the“Master Threshold” switch which makes the “Lockout” goinactive, then the unit will behave like conventional mixer.9.
