Noise Gate and Expander

Polarity Invert. Alters the polarity of the selected channel's signal
3.
by 180°. The Polarity Invert button can be used to correct out-of-
phase audio signals that are canceling/reinforcing each other.
4. 48V engages phantom power for the microphone input on the selected
channel. This feature can be individually enabled for each channel.
WARNING: Phantom power is required for condenser microphones but can
severely damage some dynamic mics, especially ribbon mics. Therefore,
switch phantom power off for all channels where it is not required.
1. Gate Threshold. Sets the gate threshold—the level at which the
gate opens—for the selected channel. If the threshold is set fully
counterclockwise, the gate is turned off (always open), allowing all signals
to pass through unaffected. You can set the threshold from 0 to -84 dB.
Power User Tip: The Gate meter in the Selected Channel area displays the amount
of gain reduction currently being applied by the noise gate/expander.
2. Gate Range. Sets the amount of gain reduction that the
gate produces. The range can be set from 0 to -84 dB. Range
control is not available when using the expander.
Gate Attack. Sets the rate at which the gate opens on the selected
3.
channel or output. You can set the attack time from 0.02 to 500 ms.
4. Gate Release. Sets the rate at which the gate for the selected channel
closes. The release time can be set from 0.05 to 2 seconds.
5. Gate On. Toggles the gate on and off for the selected channel. It
will illuminate to indicate that the gate has been enabled.
