Control Elements
Stepper Pot
HPF/LPF maximum Flat-Filter 4th Order with 24 dB/Oct
Range LPF > 25 kHz to 2 kHz, switchable 'x0.1'
Range HPF < 15 Hz to 300 Hz, switchable 'x10'

Notchfilter State variable notch filter circuitry
Frequency
Control range 20 Hz to 20 kHz in 3 Ranges selected by stepper switch(1, 10, 100)
Variation with pot > 1 to 10
Q-Factor
between 1 Octave and a Halftone
at Halftone-Setting:
- 3 dB-Points: ± fo x 1.03
Attenuation
with Pot, between 0 dB and max
max. Attenuation at Notch Frequency > 40 dB

Bypass

einzelne Bypass-Schalter


1) Depending on the settings of the control elements, attenuation is possible. The value refers to the highest level on input or output

2) Refers to linear adjustment of all parameters
