3.Leave 1st Mic Priority selected (default) to enable this feature; otherwise, clear the selection to disable it. ClearOne recommends leaving this setting on.

This setting helps maintain maximum audio intelligibility by allowing only one mic to gate on to a participant’s voice. 1st Mic Priority allows more than one microphone to be activated at the same time—it simply restricts mics 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. This audio level is then used as the ambient level for the gating group. If this feature is disabled, usually two or more microphones gate on when only one person speaks.

4.Select last-mic operation from the Last Mic Mode list. There are two options for Internal groups: Last On and Off. If you are configuring Global groups, you can select from the mic inputs assigned to the Global group in addition to Last On and Off.

Last On leaves the mic that was activated last full on until another mic input is gated on. The Input setting allows you to select which mic input the PSR1212 leaves on when all mics gate off. In a boardroom or meeting room application, this feature can be used to specify the chairperson’s mic as the last mic on. If Off is selected, all mics will gate off when no audio is present.

5.Click the Gating Group label to change the group names.

Gain

The Coarse and Fine sliders on the selected input on the Inputs 1–8 window are used to match the level settings for microphone inputs and to adjust input volume level.

Set the Coarse gain to 55dB for a mic input, 25dB for active equipment that requires an input between mic and line level, or 0dB for a line level input.

Use the Fine gain slider to adjust input volume level. You can also enter the level directly in the 0.0dB box.

Min/Max limits

Use the yellow and blue upper and lower limit arrows on the Fine gain scale to create minimum and maximum gain level limits. These limits apply only when using relative gain commands; absolute gain commands can exceed the min and max limits. Min/Max limits apply to all serially connected control devices and prevent users from adjusting levels beyond the min/max levels, provided relative gain
