Remote Control With The 25Ext; Connecting A Remote Volume Control - Intelix 4001 VC User Manual

Intelix VC Series Mic/Line Mixer User Manual

9.2 Remote Control with the 25EXT

The use of the 25EXT to remotely control the volume of
individual channels is identical to the process for the
standard VC mixer, except for the pinout of the connec-
tor. The standard VC mixer offers remote control of
channels 2, 4, 6, and 8. The 25EXT option enables the
remote control of channels 1, 3, 5, and 7. The pinout for
the 25EXT connector when configured for DC control is
shown at right.

9.2.1 Connecting a remote volume control

The following instruction show how to connect a 10K pot to a single channel as a remote
volume control. Repeat this process for each channel to be remotely controlled.
1) Remove the channel's jumper from header P1.
2) Connect a wire between one end of the potentiometer and the channel's high pin
on the DB25 connector.
3) Connect a wire between the other end of the potentiometer and a ground pin on
the DB25 connector.
4) Connect a wire from the wiper of the potentiometer and the channel's wiper pin on
the DB25 connector.
