ATI Amplifier Technologies - AT52XNC Series - Class D Power Amplifier
Newest line of amplifier is unleashed! Amplifier Technologies, Inc., the prolific manufacturer of many of the high end audio’s best amplifiers has added a new series of amplifiers. 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.
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%.”. And, 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 NC Series Amplifiers are Class D using N-Core Technology and Linear Power Supplies with Automatic 117 / 230 Voltage selection in a 3 RU chassis.
Each ATI piece is custom built to order. Please allow approximately 2 weeks for manufacturing and shipping.
The NC500 silver faceplates is custom order and available upon request in limited quantities.

FEATURES :
- Remote Trigger - Activated from 3.3VDC to 24 VDC via a heavy-duty relay
- Bottom panel ventilation
- Protection Circuits - Optically - coupled with full automatic reset
- Toroid Transformers - 40% more efficient than EI type. Each transformer has two bi-filar windings to assure low noise and cross-talk
- Circuit Boards - Double-sided, FR-4 glass-epoxy, computer-grade boards are assembled in-house
- Soft Start Circuitry - New micro-processor controlled turn-on board first ascertains input voltage and configures transformers for 120V or 230V operation then ultra soft turn-on timers reduce in-rush current to a minimum. Multiple units can be turned on without tripping circuit breakers eliminating the need for sequencing
- Amplifier Output - Hypex N-Core NC-500 Class D amplifier modules with ATI's custom input buffer insures edge-of-the-art operation
- Power Cord - 20A IEC power inlet with detachable, 3-wire cord
- 7-Year Warranty - Parts and labor against defects in parts or workmanship
