The remote volume section on the rear panel of the RM424 allows the installer to place remote vol-

ume controls in any or all of the zones connected to the RM424. Wiring information is silk screened

above each remote volume connector.

Q: Does the remote volume wire carry audio signal?

A: No, the remote volume wire only carries a DC control voltage that varies according to the position

of the remote volume pot (10-100K Ohm linear potentiometer recommended) . Use of the remote

volume feature will not introduce any noise or cause any signal loss.

Q: What is the maximum length that I can run a remote volume wire?

A: Wire size can affect the maximum length. You can run up to 200 feet reliably, and with high quality

wire up to 1000 feet.

Below is a diagram of how to connect the pots to the remote volume Phoenix connectors.

REMOTE PAD: 5 pin Phoenix connector for connection to a remote potentiometer for remote volume

control. A 100K Ohm audio taper potentiometer is recommended (others will work).

+15: Connection to potentiometer.

WIPER: Connection to potentiometers wiper (middle pin).

COMM: Common Ground for connection to pots.

As a note: If the potentiometer pad is working opposite of what you intended just reverse the wires

going to that potentiometer.
