I have 2 of these amazing ATI AT542NC 2 Channel 500 Watt Per channel amps available. They have been used for a few years in my friend's home and I am the original dealer so I know them very well. They are 100% in new working condition and they are ATI's amazing Ncore 500 Series High Power Amps with amazing reviews and incredible sound. 

The price listed is for one and of course I can work with you if you'd like both !

We carry the full line of ATI amps and we can help you with all your ATI needs !!

Feel free to call me anytime 11AM -8PM eastern time to discuss these items or any of the great items we represent.

AT542NC CLASS D AMPLIFIER MODEL

Designed and built on the musical and highly efficient Hypex N-Core® amplifier technology, the AT54XNC Series amplifiers deliver a substantial 500 watts per channel. By bridging each pair of amplifier output modules, output power is increased by 2.5x for greater headroom, loudspeaker drive and sonic impact. Available in 4 models from 1 to 4 channels, the AT54XNC Series offers efficient amplifier performance and value. High current toroidal transformers, a standard for all ATI power amplifiers, provide clean power and performance stability.

The AT54XNC Series amplifiers have been engineered for high power, compact and efficient amplifier choices for multi-channel listening systems. AT54XNC have been designed with balanced bridged output modules and paired with ATI-designed custom gain stages and a linear power supply. Each pair of balanced bridged Hypex N-Core® amplifier modules produce up to 500 watts with 4 ohm loudspeakers which are recognized by the amplifier as 2 ohm loads.

ATI’s proprietary voltage-sensing power supply automatically selects the correct voltage, therefore allowing the AT54XNC Series to perform properly from 100VAC to 260VAC. The amplifiers are protected from overload, DC faults and thermal conditions.


Remote Trigger
Activated from 3.3VDC to 24 VDC via a heavy-duty relay
Protection Circuits
Optically – coupled with full automatic reset.
Toroidal Transformers
40% more efficient than EI type. Each transformer has two bi-filar windings to assure low 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 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.
Power Supply Capacitance
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
