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/Saturation
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. Normally,
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 frequencies,
i.e. a higher or lower frequency
(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 indicated
filter:
LP The low pass filter suppresses
frequencies higher than
the CUTOFF frequency (see appropriate
section) and allows the
lower frequencies through.
