Maximum Number of Mics

This parameter sets the maximum number of microphones that can be gated on at any one time. This range can be set from one to eight microphones or off. The default setting is four. To set the maximum number of microphones, scroll through the number ranges (one through eight), select the desired number, and press Enter.

First Mic Priority

This feature helps maintain maximum audio intelligibility by allowing only one microphone to gate on when a person is speaking. ClearOne recommends leaving this setting on. When turned off, usually two or more microphones gate on when only one person speaks. However, when this parameter is turned on, one person will usually be able to gate on only one microphone. First Mic Priority works by determining the audio level received by all microphones when the first microphone is gated on. This audio level is then used as the ambient level for all other microphones. This mode can be turned on (default) or off by selecting the option and pressing Enter.

Last Mic Mode

There are three modes of last-mic operation: last on, mic 1 and off. Last On leaves the microphone that was activated last full on until another microphone input is gated on. Mic 1 allows the AP800 to revert back to a mic 1 input when all microphones gate off. The default setting for last mic mode is off. Select the setting you want to use and press Enter.

Gate Ratio

The gate ratio specifies how much louder the microphone audio level must be above the ambient level before a microphone gates on. Remember, this value is relative to the ambient level. If adaptive ambient mode is on, the actual On threshold changes as the ambient level changes. The adjustment range is from 0–50dB, in 1dB increments. Default setting is 15. If microphones frequently gate on when no one is speaking, increase the gate ratio.

Off Attenuation

This sets the amount of level reduction applied to a microphone when it is off (see Figure 2.9). Low values increase the amount of echo and reverberation allowed into the system. If the value is set high, you might be able to hear the microphones gate on and off as the background noise is reduced. The adjustment range is from

0–50dB, in 1dB increments. Default setting is 12. As more microphones are added to the system, the off attenuation should be adjusted toward 50 (high).
