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.

Attack Time

This signal parameter determines how quickly compression is enabled.

It is calibrated in milliseconds.

Attenuation

A reduction of signal amplitude.

Audio Processor

A device that modifies an audio signal in response to certain

requirements.

Audio routing

The process of routing input signals (Mics 1–8, Inputs 9-12, From

E-bus, From Processing) to output destinations (Output 1–12, To E-bus, To

Processing) in the Matrix screen.

Automatic Gain Control (AGC)

Automatically increases or decreases audio gain

to maintain a consistent audio level.

Automatic Gating

Automatically gates microphones on or off based on input levels

and other parameters programmed into the XAP 800.

Auxiliary audio

Audio that comes from line level audio sources such as video

codecs, TH2s, and CD players.

Bandwidth

The difference between the lower and upper 3dB end points of an audio

band. Also, the range or differences between the limiting frequencies of a continuous

frequency band.

Baud Rate

The number of signal transitions per second, or the clock rate of the

serial bit stream in hertz. Given 7 or 8 bits for data plus start and stop, the

approximate ASCII character transmission rate is one-tenth the baud rate.
