This parameter block represents the LO-PASS filter.
Different types of filters (Bessel, Butterworth,
Linkwitz/Riley) with slopes between 6 dB/Oct. and 24
dB/Oct. can be set as filter response. Selecting filter
frequencies between 20 Hz and 20 kHz is possible as
well.
A click with the right mouse button onto the LOPASS
field opens the Copy & Paste menu, which allows
copying all parameters of the corresponding LO- PASS
filter to any LO-PASS filters within the same project.
GAIN TRIM allows increasing the level of the
corresponding channel by up to 6 dB or lowering it by
up to 30 dB to allow level adjustment among
individual frequency bands.
The POLARITY parameter offers the possibility to
invert a channels audio signal, i.e. to rotate its phase
by 180°. Inverting the signal may become necessary
for some specific crossover settings to eliminate the
risk of sound cancellation at the crossover frequency.
The effect of the polarity parameter becomes obvious
when displaying the summed signal of the two
amplifier channels (switch set to Sum).
