MP8V2 8通道话筒放大器
8-channel Mic Amplifier

MP8V2 an 8-channel mic amplifier allows you connecting 8 mics at the same time. It has 8 totally independent high
quality preamps in one unit. Mic amplifier amplifies each channel signal carefully and natural. Combines with unique
circuit to amplifier ensures output signal more purity and clear. It features 48V phantom power, low cut, pad and
phase button in each channel. The combo MIC/INST input connector allows you choosing the proper devices in
studio or stage performance.
1、POWER: to turn on or off the device. When turn on MP8V2 lit blue LED indicator.
2、GAIN: adjust the gain of the input stage. Turn this knob clockwise raises the amount of gain applied to the input
signal.
3、PHASE: with this button the input signal is reversed in phase by 180°. When press the button, lits white LED
indicator.
4、PAD: press the button signal will be reduce by -15dB. When press the button, lits blue LED indicator.
5、LOW CUT: when the input signal is 50hz, this switch will cut 6dB signal. This normally used to eliminate rumble
and other unwanted low frequencies from an incoming signal. When press the button, lits green LED indicator.
6、48V: When press the button, 48V phantom power delivered power to the related devices. When press the button,
lits red LED indicator.
7、PEAK: peak signal LED indicator, when the signal is overload, LED lits red indicator, you should turn down the
signal level to avoid sound distortion.
8、MIC/INST: 3-pin XLR and 6.35mm combo input connector. Connects to mic or hi-Z impedance instruments.
9、OUTPUTS: 6.35mm output connectors, connects to console, active speaker such similar devices.
10、AC115V-230V: two level voltage button, choose the proper voltage according to your local voltage.
11、AC power connector, connect a standard, detachable IEC power cable (supplied) there.

MP8V2是一款八通道麦克风放大器，能同时连接八个麦克风。每个通道都带有一个完全独立状态的高质量
放大器。每路放大器都精细自然的放大输入的信号。结合独特的电子线路设计，对声音放大优化处理，让
输出音质更加清晰自然。每个通道都带有48V幻想电源，低切，衰减和相位转换按钮。其XLR/6.35mm二合
一的接口，无论您在录音室还是舞台表演都能选择适合的运行设备。
1、POWER：打开或者关闭设备。当您打开设备的时候亮起蓝色指示灯。
2、GAIN：调节输入的增益大小。顺时针旋转增大输入信号的增益。
3、PHASE：按下此开关，相位反转180°。当按下此开关的时候亮起白色的指示灯。
4、PAD：按下此开关，输入信号衰减15dB。当按下此开关的时候亮起蓝色的指示灯。
5、LOW CUT：低切按钮能够在信号为50hz进行6dB 的低频滚降，以避免不必要的低频噪音。当按下此开关
的时候亮起绿色的指示灯。
6、48V：48V幻象电源开关。按下此按钮给设备提供48V幻象电源。当按下此开关的时候亮起红色的指示灯。
7、PEAK：峰值信号指示灯，当信号过载的时候亮起红色的指示灯，此时您应该把音量调小避免信号失真。
8、MIC/INST：6.35mm,XLR二合一接口，连接话筒或者高阻抗乐器。
9、OUTPUTS：6.35mm输入接口，连接调音台，有源音箱类似设备。
10、AC115V-230V：两档电压选择开关，根据当地的电压选择合适的电压档位。
11、标准的IEC电源接口。
