O UTPUT
Sets output level of the plugin. An output limiter is set to -0.9 dB, so the signal will not clip at the DAW, but heavy
limiting will affect the sound. The LED next to the knob is a limiter activity indicator.
Range: -24 dB to +24 dB
Meters
Input or output gain is displayed on a single VU meter. Use the switch on the left to select a source. In
the stereo component, the meter displays the louder of the left and right channels.
H EADROOM A DJUST
Click on the headroom adjustment screw at the bottom of the meter to calibrate the VU meter to the DAW’s reference level.
When, for example, headroom is set to “18,” then a -18 dBFS reference tone will equal 0 dB VU on the meter.
Range: 8 dB to 24 dB
Excluding Selected Frequencies from Distortion Processing
You can use the Pre EQ and Post EQ controls together to remove certain frequencies from distortion processing.
This is most commonly used to leave low frequencies largely untouched, usually to maintain the color and
robustness of the bass or to prevent the bottom end of the distortion from becoming muddy. The idea is to use the
Pre EQ to strip away the frequencies you want to remove from the signal so that they don’t pass through the
compander and saturator, and then use the Post EQ to recover the same frequencies after processing.
1. Raise the Pre EQ low shelf value until you remove most of the low frequency sound you want to protect.
2. Set the Post EQ to approximately the same value, but opposite, of
as the Pre EQ. The selected frequencies will remain unaffected
while the rest of the signal will be distorted.
3. Adjust both controls to get the color of the output to closely match that of the input.
