Control Elements
Gain
The maximum increase or attenuation of the amplitude is adjusted to the according fre-
quency range for each frequency band. The setting can be selected with detented poten-
tiometers in 41 steps.
Maximum change in amplitude:
• LF- (Low Frequencies Cut): 22 dB
• LF+ (Low Frequencies Boost): 17 dB
• MF- (Mid Frequencies Cut): 11,5 dB
• MF+ (Mid Frequencies Boost): 10 dB
• HF- (High Frequencies): 14,5 dB
• HF+ (High Frequencies): 12,5 dB
Output
Located at the center of both sides, you will find the Output controls. The Output controls
serve as an output level regulator for the respective side, to increase or attenuate the out-
put level up to 10dB. These controls are also 41 step detented potentiometers.
Channel Switch
The two, centrally located, orange-lit switches activate or deactivate the corresponding
left and right channels.
Auto Bypass
To be able to make an objective judgment of the processed material, it is best not to have
to be toggling between the original and processed signals by yourself, but rather have it
done automatically. Plus, the fact that you do not have to move from the sweet spot and
can concentrate better on the music to optimally assess the processing is a huge advan-
tage. The Interval control determines the time that needs to elapse before the compressor
toggles between the processed and unprocessed signals. Hard left is the shortest set-
ting. To increase the interval, turn the knob clockwise.
