    Hey,
    I'm a BIG processor fan and love to always add more to my system..
    So, would I benefit from purchasing this item?
    Thanks.

    I've heard of the sonic hologram, I believe it's a proprietary circuit in Carver amps that does... something [​IMG] I haven't yet been able to determine what exactly it does, but I've heard comments about improved imaging, if that makes any sense. I doon't think it's just a virtual surround processor.

    the PCA synths a new bass tone identical to the source waveform...1 octave lower.
    So if you feed it a 38hz signal...it adds a 19hz signal to the bass for your subwoofers to have fun with. You can control the apmtitude of the new signal too. It's a lot of fun to play with.
    there's other units that do the same thing(more or less) from Dbx and Behringer too.

    Sonic Hologram generation uses "interaural cross talk cancellation" to fool the brain into hearing a different sound stage.
    To try to put that into English--when you listen in stereo your left ear hears the sound from the left speaker and a millisecond and a half later (or so), the same sound arrives from the right speaker. (This is especially true for centrally placed images.) Interaural cross-talk cancellation generates a delayed signal that's opposite in phase and is calculated to cancel the unwanted signal arriving from the other speaker. So your left ear hears only the sound from the left speaker and your right ear hears only the sound from the right speaker. It's kind of like turning your speakers into headphones.
    When it is done perfectly, the listener hears sound which seems totally independent of the speaker locations and seems to come from anywhere within the front hemisphere.
    It is highly postion dependent.

    I use a pair of PCA III units in my system. 1 on a pair of HGS-18's and 1 in conjunction with a Behringer EX1200 on a pair of Buttkickers.
    The PCA is a discontinued piece. This is the only online review of the Phase Coupled Activator that I know of.

    Sorry. No offense was intended, and I hope none was taken.

    So, will a PCA improve my bass significantly?
    What's the cheapest brand/version of it?
    What would you suggest?

    Other than the Audio Control PCA here are some links to the Behringer EX1200 and DBX 120XP
    Between the EX1200 and PCA I would suggest the Audio Control unit if you can locate one. It seems to offer better performance generating 1 octave below subharmonics. It has 2 frequency sampling ranges to select from. 100-50 Hz for 50-25Hz SH and 70-30 Hz for 35-17½ SH.
    I have no experience with the DBX unit. But from the specs it does not seem as well suited for HT.
    If you do choose to use a subharmonic synthesizer be careful. They can overload a subwoofer very easily.
