ATi AT54Xnc Series

ATi AT54Xnc Series Amplifiers

AT54XNC CLASS D AMPLIFIER MODELS

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 recognised 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.

The amplifiers are protected from overload, DC faults and thermal conditions.

There is also a 1/8” mono mini jack for +12V trigger, a gold-plated chassis ground lug, a fuse holder and an IEC 20 Amp inlet for the provided detachable power cord.

The supplied power cord will be a BS 1363 (Type G) plug for use in the UK.

ATI AT54Xnc Specifications

• 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.
