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 AT544NC 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 1, 2, 3 and 4 channel configurations.
The ATI AT544NC amplifier breaks new ground in other ways. The ATI AT544NC 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.
