I	DC Volume control port (Vol/Mute) — This port connects an Extron
	external volume control module, such as a VCM, or the MLC 52 VC
	to the PVS 204SA. The range is 0 to 10 V, where 0 V is mute and 10 V
	is maximum volume. When connected, the external volume control
	module is the sole volume controller.

VOL/MUTE

NDo not control the PVS volume via RS-232 if this port is connected to

a VCM 100, a VC 50, or an MLC 52 VC. If a VCM is controlling the volume, an MLC should not be connected to the MLC/IR/RS-232 port.

Connect the supplied, male, 3‑pole captive screw connector to this port, wiring the connector as shown in figures 2-13 and 2-14.
