Filters – Panel

Technically, in the serial FILTER 
ROUTING operating modes SER 4 
and SER 6, the left half and the 
right half of the control range 
address different parameters: 
When the knob is set to the far left 
position, you will hear Filter-1/Sat-
uration exclusively, whereas Filter-
2 is blended into the mix as you 
rotate the knob towards the center 
position. When the knob is set to 
the far right position, you will hear 
Filter-2 exclusively, whereas Filter-
1/Saturation is blended into the 
mix as you rotate the knob 
towards the center position. 

Consequently, you must set FILTER 
BALANCE

 to the center position if 

you want both filters in series (in 
equal amounts) in the signal path.

CUTOFF 2  (OFFSET) Controls the 
cutoff frequency of Filter-2. Nor-
mally, CUTOFF 2 does not operate 
absolutely, but relatively to CUT-
OFF

: The cutoff frequency of the 

second filter is subordinate to the 
CUTOFF

 value you determined for 

the first filter. However you can 
use the CUTOFF 2 knob to dial in a 
relative +/- deviation in frequen-
cies, i.e. a higher or lower fre-
quency (OFFSET). When you set 
CUTOFF

 2 to the center position, 

both filters have the same CUTOFF 
frequency. In FILTER EDIT Menu, 
you can access CUTOFF LINK ON/
OFF to sever the link between CUT-
OFF

 and CUTOFF 2. In this case the 

two knobs CUTOFF and CUTOFF 2 
are independent cutoff controls for 
Filters 1 and 2, respectively.

FILT 1 MODE & FILT 2 MODE Selects 
the operating mode of the indi-
cated filter:

 LP    The low pass filter sup-

presses frequencies higher than 
the CUTOFF frequency (see appro-
priate section) and allows the 
lower frequencies through.
