With 8 channels of signal input, automatic turning on channels with signal input, automatic or manual adjustment of channel gate action level.
Each channel can be set as a priority.
Different input level could be chosen for each input channel based on different input device. Gain of channels could also be adjusted independently.
With independent volume adjustment for each channel, high-performance 75Hz low frequency attenuation circuit.
With selection switch of 48V phantom power, two groups–CH1-4 and CH5-8.
NOMA (Number of open Microphone Attenuated) function: Line could automatically adjust output level according to the increase of channel usage.
With Aux & Control interface to control external signal light or camera controller. Audio signal of channel 1-8 could be output individually to record.
With RS-232C interface to connect with central control or external controller to control on/off of channels, powerful extension capability.
With MIC output and earphone monitoring interface. Users could turn on or turn off MIC by external controller to cut off unnecessary MIC input.
2U audio processor digital machine, easy to be installed in racks.
