Class D Stereo Amplifier Ncore NC252MP 2x250W 4 Ohm

Audiophonics MPA-S252NC XLR Amplificateur Stéréo Class D Ncore 2x150W 8 Ohm

The Audiophonics MPA-S250NC XLR is a stereo amplifier based on an amplification module Hypex Ncore NC252MP. This solution is ideal for anyone who wants to have a large power reserve (2x150W) without sacrificing sound reproduction quality. This amplifier block will be suitable for example to accompany demanding speakers, to sound large listening rooms or for studio applications requiring a large headroom without compromising the accuracy and richness of the audio message.

All components are integrated in a simple and robust 100% Aluminium housing with openings to facilitate heat dissipation. Its design also allows it to limit the impact of interference on the signal.

Hypex Ncore NC252MP Amplification Board

The amplification circuit uses a module Hypex Ncore NC252MP. It is a versatile, high-performance Class D amplifier. It offers a very comfortable power of 2x150W at 8Ω while taking advantage of the high efficiency of Class D amplifiers.

Its main characteristics are its flat frequency response regardless of load impedance, its almost frequency-independent level of distortion and its ability to reject EMI interference. Its operation is based on a self-oscillating loop controlled by phase shift and taking into account feedback only at the speaker output.

SMPS Power Supply

The NC252MP module also integrates the amplification stage. This consists of a regulated half-bridge switching power supply (SMPS) with synchronous rectification on the main output rails. Compact, powerful and efficient, this power supply is particularly suitable for supplying a Class D amplifier cleanly.

In addition, to offer complete compatibility with the voltages delivered by the various electrical networks, the power supply is equipped with an automatic input voltage doubler. The NC252MP module also has an overload protection system.

Connectivity

The MPA-S250NC amplifier has a 3-pole stereo XLR input on Neutrik NC3FAV2 sockets. The amplifier output is made on Elecaudio BP-209 24k gold-plated speaker terminals. They also accept banana plugs or forks for quick and easy connections. 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 allows the device to be switched on.

This amplifier's trigger needs to be used with a mono trigger cable (sold separately).

Audiophonics MPA-S250NC XLR
Sur les conseils d'audiophonics, et ce pour remplacer un ampli à tubes, cet amplificateur est très bon avec mon preampli Atoll pr5.1, et mes enceintes Warfedale e50.
Le son est très dynamique, équilibré et détaillé.
J'ai fait aussi un essai avec des enceintes BW 702.S3 et preampli Audio GD master 1. L'ampli arrivait à driver les enceintes, ce qui est étonnant pour un ampli de si petit gabarit, mais par contre, la restitution n'était vraiment pas top.
Tout ceci pour dire que cet ampli est vraiment une aubaine au prix proposé, et en association avec un équipement hifi standard.
Il satisfera facilement les oreilles exigeantes.

Hervorragend
Habe seit ein paar Tagen diese Endstufe, was soll ich sagen,
diese Endstufe ist der Hammer. Alles funktioniert tadellos
kein Rauschen in den Boxen. Versorge damit meine
Klipsch 8000 Standboxen und die hören sich tatsächlich noch besser an.
Die Bestellung ohne Probleme und die Kommunikation mit dem Verkäufer 1a.
Kann diese Endstufe und den Verkäufer bestens empfehlen!
Hoffe ich konnte euch bei der Entscheidung etwas helfen.

Works beautifully
...the Amp is absolutely stunning. I use it for mastering in my home studio. Never had such transparent Stereo separation and controlled Bass before. I Use it with a pair of ATC SCM12 Pro. 250W are enough to play music very loudly with my ATC's

Thank you!
