Enabling Echo Reduction - Shure MXA910 Manual

The echo reduction feature prevents the far-end signal from activating the microphone. Ideal for installations in
which per­channel DSP echo cancellation is not within a project budget, echo reduction is highly effective for con­
necting directly to a computer or video codec which hosts a single-channel echo canceller.
How It Works
An echo reference signal from the far end is routed through Dante Controller software to the microphone's pro­
cessing algorithm. The processor uses this signal to prevent the microphone from gating on and capturing audio
from the loudspeakers.

Enabling Echo Reduction

1. Use Dante Controller software to route the incoming far end audio signal to the Echo Suppression Reference
In channel on the MXA910.
2. In the MXA910 web application, enter Configuration> AUTOMIX
3. Enable echo reduction by selecting a strength setting in the pull-down menu. Soft, medium, and hard settings
provide far-end attenuation and apply gain to the reference channel to ensure proper gating.Note: the off­atten­
uation setting changes to -56 dB, and the Leave last microphone on setting is set to OFF when echo reduction
is enabled.
AES67
AES67 is a networked audio standard that enables communication between hardware components which use dif­
ferent IP audio technologies. This Shure device supports AES67 for increased compatibility within networked sys­
tems for live sound, integrated installations, and broadcast applications.
The following information is critical when transmitting or receiving AES67 signals:
• Update Dante Controller software to the newest available version to ensure the AES67 configuration tab ap­
pears.
