Loudspeaker Frequency Allocator
Product Support

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:

  1. fully integrated Phase Arbitrator section for transient-perfect reproduction.
  2. each DSP crossover leg adjustable from 6dB/oct to 42dB/oct on Low Pass and High Pass side.
  3. 4- band fully parametric equalizer in each leg.
  4. low and high shelving filters in each leg- both switchable between 6dB/oct and 12dB/oct (with q adjustment).
  5. up to 50msec delay in each leg- adjustable in 0.01msec steps (3.4mm resolution).
  6. output polarity switch in each leg.
  7. filter response display.
  8. frequency response data (.frd text file) for each loudspeaker driver can be imported and merged with filter's response.
  9. three zoom levels for viewing of the graphs.
  10. fully skinnable- GUI clearly laid out in an xml-like file.
  11. comes with two premade skins.
  12. 64bit processing throughout. SSE2 instructions utilized.
