• Pin 1 is for 10 VDC reference voltage output.
•
Pin 2 (C) has two functions:
Volume control: it can be used as a variable voltage input between 0 and 10 VDC, with 0 V giving full
attenuation and 10 V giving maximum volume.
Mute: it can be used for remote control muting. Sound is muted while this pin is shorted to ground.
•
Pin 3 is for the ground connection.
NOTE: All nominal levels are at ±10%.
