required to allow remote modem access.
• Preset
The preset pasword is created in the Unit Properties window and makes
it possible to lock certain presets. A locked preset can be executed without the
password. However, a password must be entered to edit the preset.
• Site file (File Access)
The site file password is set in the Site Properties
window and will lock the site file. Users must enter the password in order to
open the site file.
Phantom Power
Power supplied by the XAP 400 to power most condenser
microphones. The XAP 400 provides 24 volts of phantom power. This feature can be
switched off for devices not requiring phantom power.
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 400. 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–D) in the XAP
400 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 400.
Ratio
The amount of compression applied to the output signal compared with the
input signal as the signal exceeds the threshold level.
Receive audio
Audio being received from the telephone line (From Telco).
Release time
Release is a parameter which determines how quickly compression is
released after the input signal drops below the threshold.
