Shure MXA910 - Automix Modes; Echo Reduction

Shure Incorporated
47/87
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 -20 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.
Number of channels enabled Off-attenuation (dB)

4 -10
5 -12
6 -13

8 -15
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 automatically 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.
Echo Reduction
In audio conferencing, a talker may hear their voice echo as a result of the microphone capturing far-end audio
from loudspeakers.
