Control Elements
Gain
The amplitude setting ranges from -20 dB up to +20 dB. This means that you can increase
or attenuate the amplitude to a maximum of 20 dB. The maximum increase or attenuation
also depends on the selected Q-Characteristic.
1/4 Gain
Thanks to the 1/4 Gain-Switch, you can reduce a maximum increase or attenuation of
the amplitude by the factor 3/4, which regulates the potentiometer from max +/- 20 dB
to +/-5 dB cut. This gives you the possibility to perform small corrections, as common in
Mastering, in a very accurate manner. Thanks to the preciseness and sensitivity of the

10 Hz to 24 kHz.
Frequency Range:
• LF (Low Frequencies): 10 Hz bis 330 Hz
• LMF (Low Mid Frequencies): 33 Hz bis 1 kHz
• MF (Mid Frequencies): 128 Hz bis 4,1 kHz
• HMF (High Mid Frequencies): 310 Hz bis 10 kHz
• HF: (High Frequencies): 760 Hz bis 24 kHz
