Connection to output
The remote volume section on the rear panel of the RM316 allows the installer to place remote vol-
ume controls in any or all of the zones connected to the RM316. 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 posi-
tion 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 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.
