normally specified in dB (decibels). On the XAP 800, gain is adjustable from -65 to
20dB (85dB range) in .5dB increments.
Gain Structure The configuration of parameters which define gain adjustment of a
signal. The optimal input gain setting is one which provides both an adequate signal-
to-noise ratio and reasonable headroom.
GPIO (general purpose input/output) The Remote port on the rear of the XAP
TH2 unit.
G-Ware Software The XAP TH2’s setup and configuration software.
Macro A series of user-created instructions, stored within the unit, which can be
executed from an RS-232 command or contact closure.
Matrix Mixer A mixer that allows routing of any input or combination of inputs to
an output or any combination of outputs. In the case of the XAP 800, the matrix
mixer permits level control at each cross point in the matrix.
Mute A condition in which an audio signal is attenuated below the audible
threshold.
Reverberation A diffuse acoustic energy field fed and maintained by sound
reflections from the room surfaces.
Serial Command A bit description designed to execute an instruction or command.
