Audiophonics AP-300S500NC Power Amplifier Ncore NC502MP

Audiophonics AP300-S500NC: Hypex Ncore NC502MP Amplification Board

The amplification circuit uses a Hypex Ncore NC502MP module. This is a versatile high-performance Class D amplifier which offers a tremendous power of 2x500W under a 4Ω load while taking advantage of Class D amplifiers high efficiency.

Its main characteristics are its flat frequency response regardless of load impedance, its almost frequency-independent distortion level and its ability to reject EMI interference. Its operation is based on a self-oscillating loop controlled by phase shift which does not take feedback into account except at the speaker output level.

Audiophonics AP300-S500NC: NCore Technology

NCore amplifiers are the first Class D amplifiers to approach the performance of operational amplifiers, but also to surpass them in terms of sound quality. As a result, they are able to deliver clear, rich, musical sound while remaining compact. This NCore technology combines the stability of the Hypex UcD series amplifiers with lower distortion and output impedance.

Audiophonics AP300-S500NC: SMPS Power Pupply

The NC502MP module also integrates its own power stage. It consists of a regulated half-bridge switching power supply (SMPS) with synchronous rectification on its main output rails. Compact, powerful and efficient, this power supply is particularly suitable to provide clean power to a Class D amplifier.

Its power supply can work with different voltages delivered by the various electrical networks, the power supply is indeed equipped with an automatic input voltage doubler. The NC502MP module also has an overload protection system.

Audiophonics AP300-S500NC: Connectivity

The AP300-S500NC amplifier features a 2-pole stereo RCA input on gold-plated sockets, plus a 3-pole stereo XLR input for balanced signal processing. The XLR or RCA input source is selected via two switch buttons (right and left channel). The amplifier output is made on Elecaudio BP-209 24k gold-plated speaker terminals. They also accept banana plugs or spades for quick and easy connection. A 5-12V trigger connector in 3.5mm Jack format allows to control the automatic ignition of the amplifier when integrated in a compatible system. Finally, a bistable button is used to switch the unit on and off.

Audiophonics AP300-S500NC: 100% Aluminum Case and clean lines>

The Hypex NCore NC502MP amplifier is housed in a 100% black brushed aluminum case. The thick walls of this elegantly-finished case are highly resistant, providing the components with the protection they need. The natural conduction of aluminum, together with a carefully designed air flow, helps dissipate the heat generated by the module. In addition, the acrylic front panel is screen-printed with the Audiophonics logo, and the rear with the nomenclature of each input/output. Its compact size makes it easy to integrate into any audiophile installation, offering high performance in a small space.
