Description
It is a control terminal that determines
the C-channel microphone amplifier
system is in a state of operation or
standby.
At Pin 33 high, the C-channel
microphone amplifier turns on, and turns
off at low.
Please refer to the control terminal mode
table of Page No.11 for the mode setting.
It is a control terminal that determines
the R-channel microphone amplifier
system is in a state of operation or
standby.
At Pin 34 high, the C-channel
microphone amplifier turns on, and turns
off at low.
Please refer to the control terminal mode
table of Page No.11 for the mode setting.
Terminal for testing.
Please connect to ground.
The output terminal of the microphone
amplifier L-channel.
