.With 8 channels MIC inputs and 1 channel AUX input.
.Microphones can be activated by any signal input
.NOMA (Number of Open Microphone Attenuated): It can adjust the output level according to the activated channels, which avoid the feedback due to the increasing gain of the whole system.
.Remote controller can be connected to turn on/off the microphone..With one AUX in and one Line in
