Internal Gating Groups

Internal gating groups control mic inputs connected to a specific unit. Configure Internal Gating Group settings as follows:

•Enter a name in the Group Name field (optional).

•Select the First Mic Priority checkbox to enable this feature (default), or deselect it to turn First Mic Priority off.

NOTE: ClearOne recommends using First Mic Priority to maintain maximum audio intelligibility by allowing only one mic to gate on to a participant’s voice. First Mic Priority allows more than one microphone to gate on at same time, but it restricts more than one mic from gating on to the same audio source. It does this by determining the audio level received by all mics when the first mic is gated on, and then using this audio level as the ambient level for the gating group. If First Mic Priority is disabled, two or more microphones will usually gate on when only one person speaks.

•Select the Max # of Mics from the drop-down list (the default is 4). This sets the maximum number of microphones that can be gated on at any one time within a gating group. The maximum number of mics is limited to the number of mics included in the gating group. For internal gating groups, the maximum number of mics is 8 for Converge Pro 880, 880T, 880TA 8i, Converge SR 1212 and SR 1212A units, and 4 for Converge Pro 840T units.

•Select the Last Mic Mode from the drop-down list (the default is off). Last On leaves the last mic activated gated on until another mic gates on. The Input options allow you to select which mic remains on when all other mics gate off. Off gates all mics off when no audio is present. All allows all mics to gate on at the same time.

Global Gating Groups

Global gating groups control mic inputs connected to all units linked together through the Expansion Bus. Configure Global Gating Group settings as follows:

•Enter a name in the Group Name field (optional).

•Select the First Mic Priority checkbox to enable this feature (default), or deselect it to turn First Mic Priority off.

NOTE: ClearOne recommends using First Mic Priority to maintain maximum audio intelligibility by allowing only one mic to gate on to a participant’s voice. First Mic Priority allows more
