DC Volume/Mute Control
h
DC Volume control port (Vol/Mute) — This port is used to connect an Extron
external volume control module, such as a VCM 100 to the PVS 305SA. 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.
N
Do not control the PVS volume via RS-232 if this port is connected to
a VCM 100. If a VCM 100 is controlling the volume, an MediaLink Controller
(MLC) should not be connected to the MLC/IR/RS-232 port.
Connect the supplied blue, male, 3-pole captive screw connector to this port,
wiring the connector as shown in figure 2-9.
