7.3.3.2 Wiring an external combination mute switch and volume control

The following instructions show how to connect a linear 10k pot to a single channel for
remote muting and a remote mute switch. Repeat this process for each channel to be remotely
controlled.
1) Remove the channel's jumper from P12.
2) Connect a wire from one side of the switch to the
wiper pin of the channel to be muted.
3) Connect a wire from the other side of the switch to a
ground pin on the DB25 connector.
4) Connect a wire from one end of the pot to the
channel's high pin.
5) Connect a wire from the other end of the pot to a
ground on the DB25 connector.
6) Connect a wire from the wiper of the pot to the
channel's wiper pin on the DB25 connector.

7.4 Ducking

Ducking is the process of lowering the volume of selected channels when a trigger channel has
a signal present. The VCX mixer allows a wide range of control over this process (the VC
model does not support ducking.) Any channel can be defined as either ducked, duck trigger,
or no duck. The amount of ducking and the recovery time of the ducked signal are adjustable.
Once the ducking circuitry is configured, the ducking is automatic. Manual ducking can also
be performed.
All components which need to be adjusted for ducking are indicated in the drawing on the
following page. This drawing does not show the EXT25 (a standard part of the VCX mixer,
but an option on the VC mixer) board in place. All the components needed for ducking can be
reached with the EXT25 board in place. Note that for 4001 models, channels 1-4 correspond
to channels 2, 4, 6, and 8 on the PC board.
