AT602 & AT1202 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.

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 amptech@ix.netcom.com 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 channel 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.

Rack Mounting

Your amplifier may be mounted in a standard 19-inch rack by using the optional 19-inch rack mount adapter. A rack mount kit is available for your amplifier that allows it to be mounted face forward or back forward. Be careful to follow the instructions that come with the rack mount kit to ensure correct and safe mounting.
