Mixer can do the general installation and debugging after it connect the exterior device and microphone.
1、cascade mixers by “S label，open the mixer, if the link light below the noise gate encode switch is on, it
indicate the cascade is succeed, then we can set the host and slave。
2、The 8 channels of the mixer are all select the microphone input mode, it is that the 8 channels all have 48v
voltage output, if the microphone use external power ,please change the channel to the microphone input
mode.
3、Please turn the 8 channels’s volume to “12 clock”position，if the 8 channels use the microphones with
different sensitivity, pls turn the 8 channels’s volume to the same.
