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.

Custom
Custom mode provides control over all automixing parameters. This mode is useful when adjustments must be made to one of
the preset modes to fit a particular application. If parameters are changed in smooth or classic mode, custom mode automati
cally activates.
Manual
Manual mode sums all active tracks and sends the summed signal over a single Dante output. This provides the option to route
the signal for reinforcement or recording, without enabling automixing. The settings from the faders in the standard monitoring
view apply to the summed output.
Mute Sync
It’s important to be able to see if a room is muted or unmuted during a call. You want devices to show the same mute status as
the videoconferencing software. Shure devices use logic and mute sync to make this happen.
Logic: Aligns mute status across Shure devices in the room. The processor (such as a P300, IntelliMix Room software, or
an ANIUSB-MATRIX) is the controller.
Mute sync: Aligns mute between the processor and the videoconferencing software, which is on a computer connected to
the processor by USB. The processor’s automix output is muted or unmuted to change the mute status of the system.
