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 800 unit. The GPIO Builder is used to program Control/Status A pins.
G-Ware Software
The XAP 800’s setup and configuration software.
Hold Time
The length of time that a microphone remains on after the voice (input)
level drops below the gate ratio. This can be used to prevent the microphone from
gating off during brief pauses in speech.
Last Mic Mode
Sets the last-activated mic to Last On, Mic 1-8, or Off. The Last
On setting leaves the last-activated mic gated on until another mic input gates on.
Macro
A series of user-created instructions, stored within the unit, which can be
executed from an RS-232 command or contact closure.
Macro Mode
The G-Ware mode that allows you to customize and execute macro
commands for a XAP 800 unit or network.
Manual Gating
Provides the ability to gate a microphone on or off manually.
