Channel Mix (Automix)
Go to the Automix page. Use the faders to adjust a channel’s gain before it reaches the auto-mixer and therefore affects the automixer’s gating decision. Boosting the gain here will make the lobe more sensitive to sound sources and more likely to gate on. Lowering gain makes the lobe less sensitive and less likely to gate on.

IntelliMix
· Disable “Always on” for all channels. · When no sound is detected in the room, CamConnect will return to its home
position (or a defined camera preset if required).

Keeps the most recently used microphone channel active. The purpose of this feature is to retain the natural room sound in the signal so that meeting participants on the far end know the audio signal has not been interrupted.
· Off Attenuation
Sets the level of signal reduction when a channel is not active.
· Hold Time
Sets the duration for which the channel remains open after the level drops below the gate threshold.

Gating Sensitivity
Gating Sensitivity
· Changes the threshold level at which the gate is opened · Generally, this should be set between 2 and 5. Begin at level 2 and
adjust it to find the most appropriate result for your meeting space. · The higher the level, the more sensitive the voice-trigger, and the
greater the frequency of camera switching. · The higher the level, the greater the chance of picking up non-vocal
sounds.
