25K Linear Potentiometer
All PLC4.1 Controllers will accept this option for remote control of over all (master) volume control. The potentiometer is
typically installed in a single-gang electrical box with a blank cover panel drilled to accept the control. Simple 3-wire
22ga, or equivalent, interconnection. Wiring is as follows:

25K Linear Potentiometer (For PLC4.1 w/factory-installed VCA card option)
Individual channel (1, 2, 3, 4 and/or SUB) remote volume control is possible with the factory-option VCA card. (See your
Tannoy dealer). One or more potentiometers may control any PLC4.1 output(s) in any combination. This is achieved by
wiring the Master Return connection from the potentiometer(s) to the VCA RETURNS connector (one or more pins) for
the channel(s) you wish to control.
EXAMPLE: Channels 1 and 2 are feeding a stereo signal to zone #1 you wish to control. Channel 3 is feeding a mono
signal to zone #2 you wish to control separately. Wire the Master Return connection from zone #1's potentiometer to
VCA RETURN 1 and 2 connector pins. Wire the Master Return connection from zone #2's potentiometer to the
VCA RETURN 3 connector pin. The + 10V and GROUND connections are common to all used potentiometers.
