Remote Volume Control
Options for remote control of the XPA amplifiers include the Extron VCM 100 and
VC 50 volume controllers. Third party 10k potentiometer volume controllers can also be connected to this port.
As shown in the following illustration, pin V (1) on the XPA is a 10 VDC reference voltage. Pin C (2) is the volume control DC voltage input. The range is 0 to 10 V, where 0 V is mute and 10 V provides maximum volume. Pin G (3) is ground.
NOTE: All nominal levels are at ±10%.
