AT1800 Series Power Amplifiers
Congratulations! Thank you for purchasing an ATI Power
Amplifier. Designed, engineered and manufactured in the
United States, it has been carefully designed to deliver the
best possible audiophile-grade performance as well as the
most reliable operation.
The AT1800 Series is comprised of six models; the AT1802
two-channel amplifier, the AT1803 three-channel amplifier,
the AT1804 four-channel amplifier, the AT1805 five-channel
amplifier, the AT1806 six-channel amplifier and the AT1807
seven-channel amplifier. This manual covers all six models
with the only difference being the number of channels you
are using in your audio/video system.
In order to receive the maximum performance from your
new amplifier, please take a few minutes to read this manual.
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 888-777-8507.
Features
Your new ATI amplifier is a state of the art, high performance,
audio component. It is built utilizing totally complementary
circuitry. A custom-designed, toroidal transformer drives the
high current power supply with multiple windings for each
channel. Each output module employs an advanced optically
coupled protection circuit that replaces the need for
bothersome fuse changes. The amplifier is cooled by convection
through the use of custom designed, efficient heat sinks.
Unpacking
The carton and packing materials used in shipping your new
amplifier were specially designed to protect it from the shock
and vibration of shipping. We strongly suggest that you save
the carton and packing materials to use if you move, or if the
unit ever needs to be shipped back to us for any reason. Should
you discover that your amplifier has been damaged during
shipping, please contact your dealer or ATI immediately and
request the name of the carrier so a written claim may be made.
THE RIGHT TO A CLAIM AGAINST A PUBLIC CARRIER CAN BE
FORFEITED IF THE CARRIER IS NOT NOTIFIED PROMPTLY IN
WRITING AND IF THE SHIPPING CARTON AND PACKING
MATERIALS ARE NOT AVAILABLE FOR INSPECTION BY THE
CARRIER. SAVE ALL PACKING MATERIALS UNTIL THE CLAIM
IS SETTLED.
Placement
During normal home operation the heat sinks on the amplifier
will become warm. However, there are instances during high
level playback into low impedance speakers when the heat
sinks will become much warmer than usual. To ensure the
amplifier's trouble-free operation, it is necessary to provide
adequate ventilation for the heat sinks. Your amplifier should
be kept away from external sources of heat such as radiators
and hot-air ducts. The amplifier should never be placed with
other heat-producing components in a cabinet or enclosure
lacking free airflow. Do not stack other components on top of
your amplifier.
Handles and Rack Mounting
A front panel handle set for the AT1800 is available from your
dealer or ATI for an additional charge. Carefully remove the
four socket-head cap screws using an Allen wrench while
being careful to avoid scratching the front panel. Follow the
instructions that come with the handles for proper installation.
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 SUPPORT THE
WEIGHT OF YOUR AMPLIFIER. BE SURE TO MOUNT THE UNIT
ON A STRONG, WELL-SUPPORTED SHELF.
