Hard Ceiling Mounting

You can mount square ceiling array microphones in hard ceilings without a tile grid using the A910-HCM accessory.

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 while far-end audio is present.
