System Configuration ~ Inputs and Outputs

Chairman Override

Chairman Override provides gating priority for this mic input over any other mic input within the same gating control (mixer) groups. When a mic with Chairman Override enabled gates on, all mics which don’t have Chairman Override enabled will gate off. Default is off.

Adaptive Ambient

Adaptive Ambient adjusts the ambient reference level as noise and room conditions change. When adaptive ambient is on, the mic channel monitors the ambient noise level on the input and adjusts the ambient level reference automatically. This means that the gate threshold level automatically increases or decreases based on back- ground noise. If Adaptive Ambient is turned off, the input will use the fixed ambient level specified in the Ambient Level box as its gating reference. Default is on.

PA Adaptive Mode

PA Adaptive Mode uses loudspeaker audio level on a specified output as the new ambient level when audio is present at the power amplifier. This prevents loudspeaker audio from gating on the mic, while still allowing people in the room to gate on microphones as they speak—provided that their voices are louder than the loudspeaker audio. For example, you might decide to play background music from a CD player during a presentation. PA Adapt Mode allows you to use the output routed from the CD player as the ambient reference to prevent the CD player’s audio from gating on microphones. An output must be specified as the PA Adaptive Reference for each mic in the system. Default is on.

Gate Ratio

Gate Ratio specifies how much louder the audio level must be above the ambient level before the channel gates on. The gate ratio range is from 0 to 50dB. Default is 15dB.

Hold Time

Hold Time determines how long the channel stays gated on after the audio is below the threshold. The hold time range is from .1 to 8.0 seconds. Default is .3 seconds.

Off Attenuation

Off Attenuation sets the amount of level reduction applied to a channel when it is gated off. The range is from 0 to 50dB. Default is 12dB.

Ambient Level

Ambient Level is available only if the Adaptive Ambient feature isn’t enabled. Use
