The filters in BAND-MODE
With
MODE
being set to
BAND
, FILTER A‘s
CUTOFF
controls the highpass
filter. From here, the audio signal is routed into FILTER B that is configured as
lowpass (see figure “Serial combination of high- and lowpass filter” on page
27). To hear the full frequency spectrum
CUTOFF
A needs to be turned fully
left and
CUTOFF
B fully to the right. Moving the control towards each other
narrows the passing frequency range. Because the high- and lowpass filters
both cover almost the full spectrum, the audio signal may disappear at certain
overlapping
CUTOFF
settings.
Use the markers on the
CUTOFF
controls as aid to orientation. The
further the distance of the marks, the wider the passing frequency
range - very much like a fan being opened. Conversely, closing the
“fan” will narrow the passing band.
The frequency being passed through the filter, shown as “fan”.
To use
Action Filter 4
as a classic lowpass filter, select
BAND
-MODE
and keep FILTER A fully open (
CUTOFF
set fully left). Use FILTER B‘s
CUTOFF
to control the lowpass filter as desired.
Do the opposite for getting a pure highpass filter.
