3.1 Gain Compensation

When FOH-MON linking, since both consoles will be using inputs from the same mic pre, it 

may be desirable to have gain changes made to the mic pre not affect the other console. This 

is done using the digital trim on one console to compensate for changes made to the gain from 

the other. For this to work, at least one console must be designated to actually control the mic 

pre by enabling Mic Pre Master on the Setup>Linking screen as described above. 

Note: In the details below, the term “slave” and “master” refer to if the consoles are set to be a 

mic-pre slave or mic-pre master, not a FOH or Mon slave or a FOH or Mon master.

Mic Pre Master

With a Mic Pre Master console and a Mic Pre Slave console connected to a DS3232, the mic-

pre-master console has control of the Mic Pre gain, 48V, and Pad.  The Trim V-Pot control 

shows Mic Pre gain on the channel V-Pots

Mic Pre Slave

The mic-pre-slave console can display all true values of Mic Pre Gain, 48v, and Pad, but the 

Digital Trim is the only control that is adjustable. The Trim V-Pot control shows digital trim on 

the channel V-Pots.
