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.

Ambient Level The manually-set background noise level upon which the

XAP 800 bases gating protocols. Used only if the Adaptive Ambient feature

isn’t used.

Ambient Noise The existing room-level noise, such as that caused by

ventilation systems, paper shuffling, and background chatter.

Amplitude Plot A plot of amplitude (-18 to 18dB) vs. frequency (20Hz to

20kHz) on a logarithmic scale.

ASCII The American Standard Code (for) Information Interchange.

Standard code for transmitting alphanumeric characters electronically.

Attack This signal parameter determines how quickly compression is

enabled. It is calibrated in milliseconds.

Attenuation A reduction of signal amplitude.
