★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。

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。

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. The multiple mixers should be connected as indicated below: take Mixer Awhich is connected with the sound mixer for example.SpecificationMicLineLinkAuxUnbalanced Input Impedance 4000 ohms 30000 ohms 20000 ohms30000 ohmsOutput Impedance Balanced100 ohms 400 ohms 300 ohms 200 ohmsMaximum InputLevel-24dBV +30dBV +17 dBVMaximum Gain >73dB Frequency Response 30Hz - 28kHz Equivalent InputNoise-124dBV Mic/Line Input Pads 50dBPhantom Power +48VDC Control Voltage Out. +4VDCPower Supply 15V/500mA Computer Control Port RS485AccessoriesIncludedLink Cable, Rack Mount, Power Adaptor.System InstallationLink Out Link In ………Link In(A)。
