AT52XNC CLASS D AMPLIFIER MODELS
Designed and built around the musical and highly efficient Hypex N-Core® amplifier technology, the AT52XNC model amplifiers deliver a robust 200 watts of power per channel. Each amplifier channel employs one N-Core® module to drive the loudspeaker and deliver sonic impact to the presentation. Available in 7 models from 2 to 8 channels, the AT52XNC Series offers efficient amplifier performance and value. High current toroidal transformers, a standard for all ATI power amplifiers, provide clean power and stable performance.
The AT500NC Series amplifiers have been designed to be compact and efficient while still providing high power for more demanding multi-channel listening environments. The AT52XNC model amplifiers employ Hypex N-Core® amplifier modules combined with an ATI designed custom gain stage and linear power supply. Each amplifier channel produces 200 watts of output power into 8 ohm loudspeakers and 300 watts into 4 ohm loudspeakers.
Around the back of the amplifier, each channel has an RCA unbalanced input, an XLR Balanced input, input selection switch and a pair of gold-plated, 5-way binding posts for the outputs.
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.
SPEC
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.
Power Transistors:
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.
