Hypex N-Core® Class D amplifier topology
Linear power supplies
Automatic AC power recognition
Microprocessor controlled soft-start turn-on
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.

Power Requirements
Universal Auto-Select AC Voltage Ranges: 90-132 VAC or 200-260VAC – 1x 20 Amp Circuit ≤1W (120 VAC)
Power Consumption (Standby)
≤1W (120 VAC), ≤0.5W (240 VAC)
Remote Trigger
Activated from 3.3VDC to 24 VDC via a heavy-duty relay
Protection Circuits
Optically – coupled with full automatic reset
Toroid Transformers
40% more efficient than EI 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 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.
Output Stage
Hypex N-Core NC-500 Class D amplifier modules with ATI’s custom input buffer insures edge-of-the-art operation.
Power Supply Capacitance

Power Cord
Dual detachable, 3-wire cord.
