Glossary
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.
