AT4000 Signature Series
Pure Balance™ Power Amplifiers
Congratulations! Thank you for purchasing our Signature
Series Amplifier. Designed, engineered and manufac-
tured in the United States, it offers significant advances
in circuit topology and performance over virtually all
currently available amplifiers.
The AT4000 Signature Series is comprised of six models;
AT4002 two-channel amplifiers, AT4003 three-channel
amplifiers, AT4004 four-channel amplifiers, AT4005 five-
channel amplifiers, AT4006 six-channel amplifiers and the
AT4007 seven-channel amplifiers. This manual covers all
six models with the only difference being the number of
channels.
In order to receive the maximum performance from your
new amplifier, please take a few minutes to read this manu-
al. This important information will help you make certain
that the amplifier is properly configured for operation with
the rest of the equipment in your system. If you have any
questions about this product, its installation or operation,
please contact us via e-mail at [email protected] or via
telephone at (323) 278-0001.
Features
Your new ATI amplifier is a state of the art, high performance,
Page 2
audio component. It is built utilizing fully balanced circuitry.
Page 2
Dual custom-designed, toroidal transformers drive the high cur-
Page 3
rent power supply with independent secondary windings for each
Page 3
channel. Each output module employs an advanced optically
Page 3
coupled protection circuit that replaces the need for bothersome
Page 3
fuse changes. The amplifier is cooled by convection through the
Page 3
use of custom designed, efficient heat sinks.

Placement
During normal home operation the chassis and top-cover of the
amplifier will become warm. However, there are instances during
high level playback into low impedance speakers when the chas-
sis and top-cover may become much warmer than usual. To en-
sure the amplifier's trouble-free operation, it is necessary to pro-
vide adequate ventilation for the heat sinks. Your amplifier
should be kept away from external sources of heat such as radia-
tors and hot-air ducts. The amplifier should never be placed with
other heat-producing components in a cabinet or enclosure lack-
ing free airflow. Do not stack other components on top of your
amplifier.
Handles and Rack Mounting
The handles on the AT4000 Series may be removed by using an
Allen wrench. Carefully remove the four socket-head cap screws
and replace them with screws of the same diameter and pitch, but
only 1 inch long. Do not use longer bolts as they may penetrate
too deeply and damage internal parts. Your amplifier may be
mounted in a standard 19-inch rack by using the optional 19-inch
rack mount panel.
CAUTION: THE RACK MOUNT PANEL CANNOT SUP-
PORT THE WEIGHT OF YOUR AMPLIFIER. BE SURE TO
MOUNT THE UNIT ON A STRONG, WELL-SUPPORTED
SHELF.
