Echo Reduction (Firmware <4.x only)
In audio conferencing, a talker may hear their voice echo as a result of the microphone capturing far­end audio from loud­
speakers.
The echo reduction feature prevents the far­end signal from activating the microphone. Ideal for installations in which per­chan­
nel DSP echo cancellation is not within a project budget, echo reduction is highly effective for connecting 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 processing algo­
rithm. The processor uses this signal to prevent the microphone from gating on and capturing audio from the loudspeakers.
