Automix Settings
Leave Last Mic On Keeps the most recently used microphone channel active. The purpose of this fea
ture is to keep natural room sound in the signal so that meeting participants on the
far end know the audio signal has not been interrupted.
Gating Sensitivity Changes the threshold of the level at which the gate is opened
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

Priority When selected, this channel gate activates regardless of the number of maximum
open channels.
Automix Gain Meter When enabled, changes gain meters to display automix gating in real time. Chan
nels that gate open will display more gain than channels that are closed (attenuat
ed) in the mix.
Automix Modes
Classic
Classic mode emulates the Shure SCM820 automixer (in its default settings). It is renowned for fastacting, seam
less channel gating and consistent perceived ambient sound levels. Off-attenuation in this mode is fixed at -12 dB
per channel, regardless of the number of open channels.
Smooth
In Smooth mode, Offattenuation settings for each channel are scaled, depending on the number of open chan
nels. The scaled gain structure helps to reduce noise when there is a high channel count. When fewer channels
are used, the lower off-attenuation provides transparent gating.
