AT500
Series Power Amplifiers
NC
Congratulations! Thank you for purchasing an ATI
AT500
Power Amplifier, one of the most advanced
NC
audio components available. Designed, engineered and
manufactured 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 AT500
Series is comprised of ten models; the

ual covers all ten 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 AT500
amplifier was designed to provide a
NC
state-of-the-art listening experience and is suitable for
use with associated components of the highest order.
The amplifier uses the N-Core® NC-500 class D am-
plifier modules with an ATI designed custom gain
stage and linear power supply to deliver superior per-
formance.
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.
ATI's proprietary voltage-sensing power supply
which automatically selects the proper voltage and
is suitable for use with AC supply of 100V to
260V.
Extruded aluminum heatsinks to aid in cooling the
N-Core® class D amplifier modules.
This AT500
amplifier has been put through a rigor-
NC
ous and unique testing procedure ensuring that each
amplifier will last for many years with minimal service

requirements. 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 AT500
tested 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 functional test.
Unpacking
six-
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 heat sinks will become 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.
Note: While the AT500
Class-D design and generates little heat, it is imperative
that the amplifier be operated in a well-ventilated envi-
ronment and that the immediate external temperature
be maintained as specified.
