ATI Amplifier Technologies AT52XNC
The AT52XNC series amplifiers break new ground in several ways.
Package Pricing with Selected Options:
Number of Channels:
4 Channels [$815.00]
Remote Trigger – Activated from 3.3VDC to 24 VDC via heavy duty relay
Protection Circuits – Optically-coupled with full automatic reset.
Toroid Transformers – 40% more efficient than EL type. Separate bi-filar windings for each channel guaranty lower noise and crosstalk.
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 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 – Detachable 3-wire cord.
7-Year Warranty – Parts and labor against defects in parts or workmanship.
Dimensions – Two-four channel models: 17”W X 5 3/4”H X 10 5/8”
Five to eight channel models: 17”W X 5 3/4”H X 15 ½”
Weight- 39 to 62 1/2 lbs. (model dependent ).
The AT52XNC Series amplifiers use Hypex N-Core Class D output modules with ATI designed input buffers and linear power supplies. 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.
These 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. (Note: This feature is intentionally bypassed when used with the PhantomFocus System to avoid speaker/subwoofer time staggering).
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 AT500NC Series amplifiers are covered by ATI’s 7-year transferrable warranty and are available in standard (17”) chassis. A 19” rack-mount adapter kit with handles is available for $95.00.
Amplifier Technologies, Inc., is the prolific behind the scenes manufacturer of many high end and professional audio’s best amplifiers today. Amplifier Technologies owns the ATI, Audioaccess, BGW and Theta Digital brands and designs and manufactures state-of-the-art audio components for its own and other brands in its facility in Montebello, CA. Guided by legendary amplifier designer Morris Kessler, ATI offers both performance and value in audio and are a perfect compliment to the PFM line of monitors.
