High-Pass Filter Freq Adjust the High-pass Filter’s Cutoff Frequency.
The high-pass filter’s cutoff frequency can be set from 18 Hz to 1.3 kHz.
Remember that all frequencies below a high-pass filter’s cutoff
frequency are attenuated. See Section 5.3.1 for details.
The slope of the high-pass filter is -6 dB/octave.
The high-pass filter is accessible from either the Overview or Fat Channel
tabs and is available on all input channels and playback streams.
Power User Tip: A high-pass filter attenuates all frequencies below the set threshold. Use this
filter, instead of an equalizer, to remove unwanted low frequencies from your source signal.
Gate On/Off Button Turns the Gate On and Off for the Selected Channel or Bus.
This button engages and disengages the gate for the selected channel. It
will illuminate to indicate that the gate has been enabled.
The gate is available for all input and output buses.
Gate Threshold Sets the Threshold of the Gate for the Selected Channel or Bus.
The Gate Threshold determines the level at which the gate will open.
Essentially, all signals above the threshold setting are passed, unaffected.
You can set the threshold from 0 to -84 dB.
The gate can be controlled either via the
Threshold knob or from the Gate Graph.
Compressor On/Off Turns the Compressor On and Off for the Selected Channel or Bus.
This button engages or disengages the compressor for the selected
channel or output bus. It will illuminate to indicate that the compressor
has been enabled.
The compressor is available for all input and output buses.
Auto Mode Button Enables Automatic Response Mode.
When Auto mode is active, the Attack and Release controls become
inoperative, and a preprogrammed attack and release curve is used. In
this mode, the attack is set to 10 ms, and the release is set to 150 ms. All
other compressor parameters can still be adjusted manually.
Compressor Threshold Sets the Threshold of the Compressor for the Selected Channel or Bus.
When the signal’s amplitude (level) exceeds the threshold setting, the
compressor engages. Turning the knob counterclockwise lowers the
threshold so that compression begins at a lower amplitude. The threshold
can be set from -56 to 0 dB.
