Inputs
The total gain is set by setting the
gain of the input amplifier.
Channel 1 output
Channel 2 to 4 outputs
corresponding channel output.
MUTE = high: Output on
MUTE = low: Output off
∗: When the MUTE pin is open, the
Channel 1 input operational amplifier
switching function. Either amplifier A
or amplifier B is selected according to
the voltage applied to the VIN1-SW
pin.
High: V
Low: V
Controls the on/off states of the
outputs will be off. (The same as
when the MUTE pin is low.)
