Phase Plot
A plot of phase angle (-180 to 180 degrees) vs. frequency (20Hz to
20kHz) on a logarithmic scale.
Pink Noise
An audio test signal containing all the frequencies in a given audio
spectrum, with equal energy in each octave.
Preset
One of 32 configurable memories in the XAP 800. A preset can be
programmed with a variety of routing, level, gating, delay, filter, and equalizer settings
to meet specific application requirements.
Preset Mask
Defines whether a contact closure activates on a low or high signal on
the rear panel of the unit.
Preset Mode
Preset mode is used to create presets and is accessed from the G-
Ware toolbar.
Processing blocks
There are four processing blocks or channels (A–H) in the XAP
800 each with 15 filters, delay, and a compressor for pinpoint audio configuration. A
single input or group of inputs can be routed through a processing block and then
routed to an output or multiple outputs.
Q
Quality factor. It is the ratio of the center frequency divided by the bandwidth. Q
reflects an inverse relationship to the bandwidth, and adjusts from .02:1 to 40:1 on
the XAP 800.
Ratio
The amount of compression applied to the output signal compared with the
input signal as the signal exceeds the threshold level.
Release time
Release is a parameter which determines how quickly compression is
released after the input signal drops below the threshold.
Reverberation
A diffused acoustic energy field fed and maintained by sound
reflections from the room surfaces.
S–Z buses
These eight buses are defaulted as auxiliary mix buses. They are used to
route auxiliary audio to and from other units on the network. These buses are also
used as mic mix buses when NOM count is not required.
Serial Command
A bit description designed to execute an instruction or command.
Serial mode
The serial mode determines the format in which serial commands
return—text or binary. The mode defaults to Binary when G-Ware is connected
and to Text when disconnected. Contact technical support for instructions on using
Binary mode.
