The AT5XXNC amplifiers use Hypex N-Core Class D output modules with ATI designed input buffers and linear power supplies and are available with two power configurations. The AT52XNC amps are rated at 200W RMS per channel at 8 ohms with 300W RMS at 4 ohms and are available with 2 to 8 channels. The AT54XNC amplifiers use two N-Core modules per channel in a differential bridged output configuration delivering 500W RMS per channel at 8 ohms and 900W RMS at 4 ohms. The AT54XNC amplifiers are available with 2, 3 or 4 channels and are named as follows:
All power ratings are RMS @ 8-ohms, 20-20kHz
These AT5XXNC series amplifiers break new ground in other ways. They are the first ATI amplifiers to use micro-processor control for turn-on delay and feature automatic AC power recognition and configuration. The amplifiers not only recognize whether they are hooked up to 117V or 230V nominal power, 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.
