John,
Yes, the PCA is being used in my HT, the way I currently have it hooked up is LFE>PCA>ART 351 EQ>AMP>SUB. The sub is a 15" Tempest DIY Sonosub, I am very pleased with the results especially for TV broadcasts.
I would also like to lower the subsonic filter but I don't think I can...
I recently purchased an AudioControl PCA (original not 3)without the users manual. Does anyone know how to adjust the crossover freq or where I can find the manual online?
Thanks
Frank
