Function
DC 8 to 15 V is applied (rated voltage 12 V)
Maximum input 3.4 Vrms (Typ.)
Maximum output current 10 mA (Typ.) built-in short
circuit protection circuit
Can be used for wire repeater to GND, etc.
Left/right simultaneous volume or channel 1 volume is
controlled by this value in the range of 0 to 5.2 V DC.
5.2 V for pass through
Transit noise to the ear is softened by slowly switching
between pass through and VCA with time constant when and 0 V for VCA
the pass through switch is turned on/off. The time
constant is determined by externally connected
capacitor. T(sec) = 1.2

Balance or channel 2 volume is controlled with 0 to 5.2 V
Operates as VCA with 0 V, and passes through the input
to output with 5.2 V
Operates as channel 1 volume at pin 8 and as channel 2
volume at pin 10 with 0 V.
Operates as channel 1 and channel 2 simultaneous
volume at pin 8 and as balance at pin 10 with 5.2 V.
