Dante Channels
The automatic coverage setting changes the number of Dante outputs on the MXA920.
Automatic Coverage On
1 automix output with IntelliMix DSP for all coverage areas
1 AEC reference input
Note:
When automatic coverage is on, Dante Controller shows 8 transmit channels and the automix output. The automix output is the only channel that sends
audio with automatic coverage on.
Automatic Coverage Off
Up to 8 separate Dante outputs (1 for each lobe)
1 automix output with IntelliMix DSP
1 AEC reference input
IntelliMix DSP
This device contains IntelliMix digital signal processing blocks that can be applied to the microphone's output. The DSP blocks
include:
Acoustic echo cancellation (AEC)
Automatic gain control (AGC)
Noise reduction
Compressor
Delay
To access, go to the IntelliMix tab.
DSP Best Practices
Apply DSP blocks as needed. Run a test of your system without DSP, and then add processing as needed to fix any is
sues that you hear in the audio signal.
Unless you encounter video that lags behind audio, set delay to off.
Acoustic Echo Cancellation
In audio conferencing, a far-end talker may hear their voice echo as a result of a near-end microphone capturing audio from
loudspeakers. Acoustic echo cancellation (AEC) is a DSP algorithm which identifies the far-end signal and stops it from being
captured by the microphone to deliver clear, uninterrupted speech. During a conference call, the AEC works constantly to opti
mize processing as long as far-end audio is present.
When possible, optimize the acoustic environment using the following tips:
Reduce speaker volume
Position speakers farther from microphones
Avoid pointing speakers directly at microphone coverage areas
