selectable functions. As mentioned above two resonance peaks will be formed
in phaser operation, meaning there are two frequencies where the phaser with
increase of resonance tend to oscillate, shown further below.
Filter function
The double assigned
12-pos.-rotary switch (12) allows the selection of 12
different functions.

B6/12: 6 db / 12 db band-pass
B12/6: 12 db / 6 db band-pass
H6: 6 db high-pass
H12: 12 db high-pass
H18: 18 db high-pass
The decibel values mean the slope of the roll-off range, commonly denoted in
db per octave. For simplifying "octave" is omitted, because for typical filters
the values implies that db/octave is meant. Fig. 7 shows this exemplarily for a
low-pass. For band-passes two roll-off ranges exists, one with high-pass
character before and one with low-pass character behind the center
frequency.
