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.



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.
