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 PSR1212 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 PSR1212.

Auxiliary audio Audio that comes from line level audio sources such as video codecs, XAP 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.

Chairman Override Provides gating priority for chairman override enabled microphones within the same gating group. When a mic with chairman override gates on, all mics which don’t have chairman override enabled and are in the same gating group will gate off.
