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.
