Crossover Filters, Band-Pass Filters and Polarity
Set: BP Filters Independently
When you enter the "XOVER" Sub Menu, you are given three
options for how the band-pass filters can be set. When Set "BP
Filters Independently" is selected, the Channel A and B high-
pass and low-pass filters are individually set.
Set: BP Filters Channel B=a
If you are using the amplifier in a stereo system where both
channels will be set the same, select "Channel B=A" and both
channels will be set at once. Setting the filters for Channel A
also sets Channel B.
Set: X-Over Freq a Lows B Highs
If you create a crossover between channels of the amplifier,
select "X-over Freq A Lows B Highs" and crossover frequency
and filter type can be set with one set of controls. Set by
crossover screen, High-pass and Low-pass screens.
The filter types available for the high-pass and low-pass filters are:
Off
No filter
BW-12 dB
Butterworth filter with 12 dB per octave slope. -3dB at corner frequency.
Butterworth filters have a flat frequency response in the pass-band.
BW-18 dB
Butterworth filter with 18 dB per octave slope. -3dB at corner frequency.
Butterworth filters have a flat frequency response in the pass-band.
BW-24 dB
Butterworth filter with 24 dB per octave slope. -3dB at corner frequency.
Butterworth filters have a flat frequency response in the pass-band.
LR-24 dB
Linkwitz-Riley Filter with 24 dB per octave slope. -6dB at corner frequency.
LR filters combine for a flat response at the corner frequency.
It is generally a good idea to use a high-pass filter for all loudspeakers.
Unlike the other function Sub Menus, the input mode does not
change until you select "Save and Apply" and return to the
Main Menu.
