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
