Product Description

ATI AT54x Nc Series Power Class D Amplifiers

AMPLIFIER TECHNOLOGIES, INC. INTRODUCES NEW CLASS “D” AMPLIFIERS USING HYPEX N-CORE OUTPUT MODULES AND IN-HOUSE LINEAR POWER SUPPLIES. 

ATI AT54x Nc : 500W RMS PER CHANNEL AT 8 OHMS WITH 2 TO 4 CHANNELS

Montebello, CA , September 1, 2016 – 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 AT54x Nc 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 ATI AT54x Nc 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 ATI AT54x Nc amplifiers are available with 2, 3 or 4 channels.

These ATI AT54x Nc 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 recognise 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.

All ATI AT54x Nc amplifiers are covered by ATI’s 7-year transferrable warranty and are available in standard (17”) chassis. A 19” rack-mount adapter is available
