This parameter block represents the LOPASS filter.
Setting different filter types (Bessel, Butterworth,
Linkwitz/Riley) with slopes between 6 dB/Oct and 24
dB/ Oct and cut-off frequencies between 20 Hz and 20
kHz is possible.
0 dB -30...+6 dB GAIN TRIM is for increasing the level of the
corresponding channel by up to 6 dB or attenuating it by
upto 30 dB, it is used to match the output levels for each
fre- quency band.
normal normal, inverted POLARITY allows inverting a channel, e.g. shifting its
phase by 180°. Some cros- sover settings need phase
inversion to prevent cancellations in the frequency
response at the crossover frequency.
0 cm 0...68643 cm DELAY is used to delay the signal of the corresponding
way. Typically, this delay is used as time alignment delay
to overcome the difference in distance between the
loudspeaker components within a cabinet.
BYPASS activates (not engaged) or deactivates
(engaged) the corresponding delay.
The arrow sign next to SPEAKER opens a dialog for
selecting speaker files.
The text field shows the name of the currently loaded
speaker file.
