The Loudspeaker Frequency Allocator
is a 4-way, stereo DSP loudspeaker crossover that works with
ASIO compatible multichannel sound cards on a Windows XP computer.
Macintosh version is coming as well. Layout of each crossover
leg is consistent with the way professional loudspeaker design
software packages work. User is not limited to pre-canned
filter algorithms such as B3 or LR4 that are so prevalent
in the available hardware and software crossovers on the market
today. Instead, we provide a series of flexible processing
blocks that can be individually optimized to deliver the best
match for the loudspeaker drivers used. Textbook filter settings
are of course possible (either through direct input or by
recalling factory patches), as are a vast range of other settings.
A brief list of features:
fully integrated Phase Arbitrator
section for transient-perfect reproduction.
- each DSP crossover leg adjustable from 6dB/oct to 42dB/oct
on Low Pass and High Pass side.

in each leg.
- low and high shelving filters in

- output polarity switch in each leg.
- filter response display.
response data (.frd text file) for each loudspeaker driver
can be imported and merged with filter's response.
