ATI AT542NC Amplifier - Class D Series

2 Channels - 500 Watts/Channel

Amplifier Technologies, Inc., the prolific manufacturer of many of the high end audio's best amplifiers today added a new series of amplifiers. The ATI AT542NC amp and the entire AT540NC amplifier series use Hypex N-Core Class D output modules with ATI designed input buffers and linear power supplies. These amplifiers use two N-Core modules per channel in a differential bridged output configuration delivering 500W RMS per channel into 8 ohms and 900W RMS into 4 ohms. The AT540NC amplifiers are available in 2, 3 and 4 channel configurations.

The ATI AT 542NC amplifier breaks new ground in other ways. The ATI AT 542NC amp is the first ATI amplifier to use a micro-processor control for turn-on delay and feature automatic AC power recognition and configuration. The amplifiers not only recognize whether they are connected up to 117V or 230V nominal power, but they automatically self-configure. The amplifiers also incorporate a new and novel "sleep" circuit. When the amplifier receives no input signal for a period of 10 minutes, power is removed from the output modules and a front-panel LED begins to flash. As soon as an input signal is detected on any channel, normal playback operation resumes instantaneously.

Per Morris Kessler, ATI's president and chief engineer, "We are excited to offer amplifiers with ATI's legendary high performance and reliability in designs that reduce amplifier weight by up to 50%."

With rated distortion below 0.05% and signal-to-noise ratio of 123 dB (minimum, referenced to rated output), each amplifier in the series is capable of playing back the full dynamic range available on today's lossless recordings.

Made In The U.S.A.

The U.S. has always led the world in power amplifier technology, and still does. All ATI products are manufactured in Southern California in a modern 50,000 square-foot facility to exacting design specifications and rigid quality control. ATI manufactures all toroid transformers and assembles all circuit boards in-house. We use computerized Audio Precision test equipment to test each stand-alone amplifier module (DMC2) as well as the completed unit. This control and scrutiny of every phase of manufacturing guarantees unit-to-unit repeatability and a lifetime of accurate sound reproduction.
