Ati (Audio Technologies Inc.)

Ati (Audio Technologies Inc.) is a second catalog record for Amplifier Technologies Inc., the Los Angeles amplifier company set up in June 1994 by Morris Kessler and Mike Pontelle after Kessler's earlier company SAE was sold in 1988. The two listed models here, the AT2007 and AT6012, come from an earlier generation of ATI products aimed at home-theatre and multi-room installers. The main ATI brand page in this catalog covers the current range.

Range & what it's known for

The AT2007 is a seven-channel amplifier rated at 200 watts RMS per channel into 8 ohms from 20 Hz to 20 kHz with under 0.03 percent distortion, built as a true differential design from input to output under ATI's Pure Balance name, with soft-start circuitry, a detachable IEC cord and convection cooling. The AT6012 is a twelve-channel amplifier of 60 watts per channel for multi-room installations, assembled from six two-channel modules with a motorised gain control per zone, so volume can be set remotely from each room instead of through wall-mounted attenuators. Both use the optically coupled protection circuits ATI has kept in its later designs.

Who owns it and where it's made

The company behind both records is the same privately held Amplifier Technologies Inc. headed by Morris Kessler, who remains its president and chief engineer. The amplifiers were designed and assembled in ATI's own Southern California plant, and the company has since added Theta Digital, BGW and Datasat to its group.

Who it's for

This entry is for owners of an older ATI installation looking up an AT2007 or AT6012 they already have, or for buyers considering one on the second-hand market. The AT2007 suits a seven-channel surround system that needs a single high-power chassis, while the AT6012 is a distribution amplifier for six stereo zones with central remote control. Anyone buying new should look at the current ATI brand page instead, where the AT4000 and AT6000 Signature Series and the AT7012 distribution amplifier are the direct successors.
