Automix Settings
Leave Last Mic On
Keeps the most recently used microphone channel active. The purpose of this feature 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 the gate
threshold
Maximum Open Channels Sets the maximum number of simultaneously active channels
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. Channels that
gate open will display more gain than channels that are closed (attenuated) in the mix.
Automix Modes
Classic
Classic mode emulates the Shure SCM820 automixer (in its default settings). It is renowned for fast-acting, seamless 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 channels. The scaled
gain structure helps to reduce noise when there is a high channel count. When fewer channels are used, the lower off-attenua-
tion provides transparent gating.
