H-CAT™ Facts from Roger Paul

  • H-CAT™ does not involve the use of opposite channel information or phase inversion or crosstalk.
  • H-CAT™ does not use negative feed back (NFB) to remove distortion.
  • H-CAT™ is 100% pure analog and has no sampling or digitizing or processing of any kind.
  • The Wavefront Timing Control really does adjust the timing of the wavefront.
  • The WTC allows the output of the H-CAT™ preamplifier to successfully interface with the rest of your system.

     The bottom line is simply to be in the same room with this technology and to listen for yourself. When properly set up - the playback electronics including your speakers will "disappear" and your listening room will be magically "spliced" to the original venue - ranging from an intimate booth to a full size concert hall with an unlimited number of instruments, each occupying their own space.

Unlike conventional systems - no matter how complex the score, the natural display of this acoustic image will remain true.


Home Theater Bypass + Wavefront Timing Control

     Yes it has home theater bypass (HTB) and yes you can still use the Wavefront Timing Control in this mode. This allows you to trim the velocity of the soundtracks of your favorite movies. When switching to this mode - the letters “VOL” on the display will switch to “HTB” to remind you that the volume setting is independent for this input and is stored in memory.

Making the most of H-CAT™

     The manual recommends a "star" ground where the preamplifier alone is grounded to a wall outlet and everthing else is ungrounded. This is the only way to assure you have no ground loops. Please try this - the results are worth it. This is true even if you don't own H-CAT™
