AT3300 Series Power Amplifiers
Congratulations! Thank you for purchasing an ATI
AT3300 Power Amplifier, one of the most advanced
audio components available. Designed, engineered and
assembled in the United States, it has been carefully
designed and tested to deliver the best possible audio-
phile-grade performance as well as the most reliable
operation.
The AT3300 Series is comprised of seven models; the
last digit in the model number is the number of chan-
nels in the amplifier. This manual covers all seven
models.
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 instal-
lation or operation, please contact us via e-mail at sup-
[email protected] or via telephone at 323-278-0001.
Features and Testing
Your AT3300 amplifier was designed to provide a state
-of-the-art listening experience and is suitable for use
with associated components of the highest order. Each
module includes an ATI designed custom gain stage
and linear power supply to deliver superior perfor-
mance.
Additional features include:
Custom soft-start circuitry to minimize any turn-on
power surge;
Complete protection from overload, DC faults,
over-voltage or over-temperature conditions.
Extruded aluminum heatsinks to cool the amplifier
channels.
Two computer grade 2000 RPM 140mm PWM
fans, 1 per 4 channel module.
This AT3300 amplifier has been put through a rigorous
and unique testing procedure ensuring that each ampli-
fier will last for many years with minimal service re-
quirements. This procedure includes the following:
All assembled circuit boards are given a thorough
visual inspection and are then performance tested.
The tested, assembled circuit boards are then in-
stalled in a new AT3300 and the whole unit is test-
ed for every function and parameter.
AT3300 Manual
The unit is put on a burn-in torture rack to test for
any possible component failures.
The amplifier then undergoes a critical listening
and final functional test.
Unpacking
Your amplifier is a precision electronic instrument and
should be properly packaged any time shipment is
made. The carton and packing materials used in ship-
ping 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 dis-
cover that your amplifier has been damaged during
shipping, please contact your dealer or ATI immediate-
ly 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 MA-
TERIALS ARE NOT AVAILABLE FOR INSPEC-
TION 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 in-
stances during high level playback into low impedance
speakers when the heatsinks will become warmer than
usual. To ensure the amplifier's trouble-free operation,
it is necessary to provide adequate ventilation for the
heatsinks and fans. 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 enclo-
sure lacking free airflow. Do not stack other compo-
nents directly on top of your amplifier.
NOTE: It is imperative that the amplifier be operated
in a well-ventilated environment and that the immedi-
ate external temperature be maintained as specified.
NOTE: Since the AT3300 amplifiers use fans to aid in
cooling, the height of the foot allows for sufficient
space below the amplifier but additional space above
the amplifier must be provided to allow for the fans to
operate properly and quietly. A minimum of 1RU (1.75
inches) is recommended. When rack mounting the am-
plifier, additional space above and below the amplifier
must be maintained. 1RU is recommended here as well
and can be provided by blank or ventilated rack panels
depending on the cooling design of the installation.
