Gain Limiting and the Speech System

The Speech System always maintains NOM = 1, which prevents Gain Limiting from
sensing excess gain. Typically, the

NOM

controls have no effect when using the

Speech System. However, the

NOM

function can help avoid feedback when

•

mics are switched to manual;

•

the Master

OVERRIDE

button is pressed with multiple mics selected.

If either case applies,

Turn on

NOM

for all channels.

Set the

NOM gain limit

field to

If channels are set to both Speech and Music Systems, you can choose whether they
should interact. If you do not want the master gain reduction of the Music System
mics to affect those in the Speech System, turn the

NOM

buttons off for the Speech

System channels.
