Erica Synths LXR Eurorack Drum Module (28 HP) - Manual (Page 25)

Unit gain bandpass
The unit gain bandpass is a scaled version of the normal bandpass filter. The gain is always adjusted
to have its maximum around 0dB gain. Unlike the normal bandpass, where the resonance controls
the amplitude of the peak gain, it controls the width of the passband.
Notch
The notch filter removes frequencies around the set filter frequency. Again, the resonance controls
the width of the stopband.
