Glossary
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.
Clipping
A condition in which a signal level exceeds the maximum level a circuit can
handle.This is usually caused by improper gating parameters and gain settings. It
causes distortion and typically leads to listener fatigue and accelerated failure of
loudspeaker drivers.
Compression
An induced reduction in the dynamic range of part or all of an audio
signal. Compression is usually used to protect individual loudspeaker components
from the damaging effects of transients.
Compressor
The compressor is part of the processing settings and allows you to
change the gain transfer characteristics of the signal path and to control the
dynamics of the signal.
Configuration mode
Configuration mode is the default mode in G-Ware and is
used for system setup. It provides access to the Matrix and Flow Screens. See also
Preset mode and Macro mode.
Control bus
Part of the expansion bus, the control bus passes control information
to the units. Control is not affected by master/slave settings and will continue to
function even if the units are not using the audio channels.
Constant Directivity Horn Equalizer (CD Horn EQ)
Horn drivers commonly
used in arrays in arenas and auditoriums have an inherent 6dB/octave high frequency
rolloff.The XAP 800’s CD Horn EQ compensates for this characteristic.
Crossover
A device that passes designated frequency segments of an audio signal to
various loudspeaker elements in a sound system.
• Bessel A crossover using a low-pass filter design characterized by a linear
phase response.This results in a constant time delay throughout the passband.
• Butterworth A crossover using a low-pass filter design characterized by a
maximally flat magnitude response.This results in no amplitude ripple in the
passband.
• Linkwitz-Riley A fourth-order crossover consisting of a cascaded second-
order Butterworth low-pass filter. Offers a vast improvement over the
Butterworth crossover and is the de facto standard for professional audio
active crossovers.
