There are two styles of automixer groups – gating and gain-sharing. The con-

Gating Automixer Parameters
NOM Limit
NOM Limit specifies the maximum number of microphones that can be gated
on for a particular gated automixer group. This does not affect a gain sharing
mixer.
Hold Time
Hold Time specifies the amount of time a channel will remain active after the
last detected significant signal level. This should be set long enough to remain
active during short pauses in speech.
