Acoustic Echo Cancellation (AEC)
A process in which acoustical echo is removed from a signal. AEC can be used to remove unwanted
signals from mic audio if the unwanted acoustic signal is available separately as an electronic signal.
Adaptive Ambient
This portion of the mixer monitors the varying ambient noise level in the room and changes the threshold
level at which a microphone gates on.
AEC Reference
AEC References allow you to combine multiple audio sources for applications where there are two
speakers (left and right), combined audio/video conferencing, and audio/video teleconferencing. In these
and other multiple output applications, using AEC references improves AEC performance.
Ambient Level
A user-defined background noise level used to control microphone gating (used only if Adaptive Ambient is
disabled).
Ambient Noise
The existing room-level noise, such as that caused by ventilation systems, paper shuffling, and background
chatter.
Attack Time
Determines how quickly compression is enabled (calibrated in milliseconds). See also Compression,
Compressor, and Threshold.
Attenuation
A reduction of signal amplitude.
Audible Hook Indication
A series of beeps that indicates when the telephone line goes on or off hook. This feature can be turned on
or off, and the level can be adjusted in the Telco Receive Channel Properties.
Audible Ringer Indication
When a call comes in, you can hear it ring if Audible Ringer Indication is turned on in the Telco Receive
Channel Properties. The ringer level can also be adjusted.
Audio Routing
The process of routing input signals to output channels in the Matrix based on default or user-defined cross
points. See also Matrix.
