First Mic Priority
Increases the audio level required to gate on additional
microphones after the first mic is on. This helps ensure that only one mic gates on
when a person speaks.
Flow control
The regulation of the transmission and reception of data.
Flow Screen
The Flow Screen is the main access window for G-Ware features and
unit configuration. It also shows a detailed block diagram of the audio signal—
presenting a graphical explanation of each stage in the signal path.
Gain
The amount a signal is increased over a given reference, typically 0. Normally
specified in dB (decibels). On the XAP 400, 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.
Gate
The activation and deactivation of microphones.
• Auto The microphone will gate on according to the input level, assigned
gating parmeters, and gating group.
•
Manual On
The microphone will gate on unless it exceeds the NOM
requirements of the gating group.
•
Manual Off
The microphone is deactivated.
Gate Ratio
Specifies how much louder the microphone audio level must be above
the ambient sound level before a microphone gates on.
Gating controls
The gating parameters that are assigned to a gating group:
Maximum Number of Mics, First Mic Priority, and Last Mic Mode.
Gating groups
A set of gating parameters which can be applied to local
microphones (Internal 1–4) or to microphones connected to other units on the
network (Global A–D). Gating groups provide greater flexibility and control of mics.
Gentner Distributed Echo Cancellation
ClearOne’s proprietary system for
applying echo cancellation individually to each mic input.
Global gating bus
Part of the expansion bus, these four mix-minus buses pass mic
status and gate parameter information such as First Mic Priority and Max NOM.
GPIO (general purpose input/output)
The Control/Status A and B ports on the
XAP 400 unit. The GPIO Builder is used to program Control/Status A pins.
G-Ware Software
The XAP 400’s setup and configuration software.
