4 In / 4 Out Digital Audio Processor
The Filter Setup tab for the left channel high
frequency output (output 2) is shown to the right.
Note that the first two user adjustable filters are
both set to 12db/octave (i.e. 2nd order) high pass
filters with a cut off frequency of 500Hz. These
two Butterworth filters in series produce the high
pass section of the 4th order Linkwitz-Riley
crossover filter.
For a mono three-way or four-way crossover, the
input/output matrix would be set to send one
input to three or four outputs, respectively. The
band pass sections of these crossovers would be
implemented using two LP12 user adjustable
filters for the high frequency corner and two
HP12 user adjustable filters for the low frequency
corner. An example filter setup is shown to the
right for a band pass section with a low frequency
corner of 150Hz and a high frequency corner of
2kHz.
These steps are all that is necessary to imple-
ment the basic crossover. 10 user adjustable
filters (or 8 for the band pass sections of multi-
way crossovers) are still left for further driver
equalization and ADFE. Compression, limiting,
delay, and gain may also be applied to each
driver as necessary.
