Remote Connector Pin Conﬁguration

As shown at right,

Pin 1 is reference voltage.

Pin 2 is volume control with DC voltage.

Pin 3 is ground.

N All nominal levels are at ±10%.

For proper volume control, use all three pins when

connecting the device (see diagram).

The Extron VC 50 is a remote volume controller designed to work with the Extron PoleVault

™

switcher (PVS 204SA with amp), the MLP (Mic to Line Pre-ampliﬁer), and the MPA series

audio ampliﬁers (e.g. MPA 122).

Mounted into standard one-gang wall box or mud ring, the VC 50 has a rotary volume control

knob, which provides easy adjustment and ensures precise volume levels.

Captive screw connectors on the back panel provide quick and easy connectivity.

Audio Level Setting Procedure

To set the system level not to exceed the maximum volume when

using the VC 50, do the following:

1. Reduce the power ampliﬁer volume to minimum.

2. Turn the Volume knob on the VC 50 to the maximum position.

3. Slowly turn up the power ampliﬁer volume to the maximum

undistorted sound level allowed for the application.
