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.

Typical DC Voltage

5.5 V

4.8 V

5.2 V

12 V

Left/right simultaneous volume or channel 1 volume is

controlled by this value in the range of 0 to 5.2 V DC.

Transit noise to the ear is softened by slowly switching

between pass through and VCA with time constant when

the pass through switch is turned on/off. The time

constant is determined by externally connected

capacitor. T(sec) = 1.2 × C × 20k

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.

Maximum input 3.4 Vrms (Typ.)

5.2 V for pass through

and 0 V for VCA
