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 400 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.

Audible Hook Indication The unit signals when it goes on or off hook with a series of beeps. This indication can be turned on or off in the Telco Configuration window and the level can be adjusted.

Audible Ringer Indication When a call comes in, you can hear it ring if Audible Ringer Indication is turned on in the Telco Configuration window. The ringer level can also be adjusted.

Audio Processor A device that modifies an audio signal in response to certain

requirements.

Audio routing The process of routing input signals (Mics 1–4, Inputs 5–8, From Telco, From E-bus, From Processing) to output destinations (Output 1–9, To Telco, 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 400.

Automatic Level Control (ALC) ALC can be selected for the telco input and is designed to keep soft and loud telephone participants at a consistent level. ALC can be turned on (default) or off.
