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.

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 have either: a NEMA 5-15 plug (Type B) for use in the USA, a BS 1363 (Type G) plug for use in the UK, or a Schuko (Type F) plug for use in the EU and the rest of the world.
