Carver C-4000 Sonic Holography - Autocorrelation Preamplifer in very good condition. It has been serviced and fully tested. Includes the original owner's manual and our original Performance Verification Report.

From Carver:

At its heart the C-4000 is a high performance console preamplifier with precise RIAA phono equalization, low distortion, high slew rate, wide dynamic range, and a high degree of control flexibility.

But its similarity to other fine preamps ends there. The C-4000 goes far beyond mere accuracy and fidelity: it's goal is a dramatically higher degree of realism than has ever been achieved before in audio reproduction.

Thus its Peak Unlimiter undoes the dynamic compression which makes many recordings and broadcasts sound canned.

It's Auto Correlator noise reduction system strips away the veil of low level rumble and hiss which form a perpetual psycho acoustic barrier to realism in the reproduction of musical timbres.

And its Time Delay and revolutionary Sonic Hologram Generator break through the limits of listening-room acoustics and the two channel stereo medium itself to provide a remarkably three dimensional you are there realism, with a sonic image which subjectively extends far beyond the loudspeakers in both breadth and depth.

From the manual section on Sonic Holography:

"Sound images will exist to the left and to the right, well beyond the limits of the loudspeakers. A very occasional sound image may exist all the way to your right or to your left. The 'front-to-back' or 'stage' depth will be from 10 to 20 feet in front of you, with sound images clearly floating in space behind, and from time to time, in front of the loudspeakers. You can turn your head to 'look' at the sound images and they will stay 'put' in space. Sound images will clearly emerge from beyond the limits of the room boundaries. At your listening position, and from all around you, including over your shoulders, you will sense (and this is very hard to describe) an almost palpable 'feel' of the space or 'sonic signature' that belongs to the concert hall or recording studio. The sense of the hall is related to very low frequency standing-wave energy, and the complete illusion will be convincing, believable and well defined".
