Audiophonics MPA-S125NC RCA

Power amplifier NCORE NC122MP 2x75W 8Ω Black

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

An amplifier with solid performance

The Audiophonics MPA-S125NC incorporates a Hypex Ncore NC122MP power amplifier module.

This is a solid base to build a powerful stereo HiFi system, capable of delivering 2x75W under 8Ω.
On a single double-sided PCB it is composed of a low power supply for standby, a high-performance switching power supply but above all an extremely efficient Class D amplifier circuit.

The amplifier used on this NC122MP module offers a high efficiency of 92% and allows it to be used for very different uses, whether for studio use or to be integrated into a high fidelity audio system.

The distinctive characteristics of this amplifier are its linear frequency response whatever the load impedance and consequently its accurate restitution, its very low distortion but also its very low EMI radiation rate
The control of the amplifier is based on a self-oscillating loop with phase shift, taking into account the feedback only at the output of the loudspeaker, always with sound transparency in mind.

The main SMPS power supply to the amplifier is a regulated, high power, high efficiency half bridge converter with synchronous rectification on the main output rails. An ideal power supply to provide this Class D amplifier with the power it needs.
In order to be compatible with supply voltages of 100-120V and 200-240V, it is equipped with an automatic input voltage doubler.

POINTS CLÉS :

  • High efficiency
  • Load-independent flat frequency response
  • Low output impedance
  • Frequency-independant ultra low distorsion
  • Very low noise
Hypex NC122MP

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 reproduction quality. 
Thus, they are able to deliver a clear, rich and musical sound while remaining compact.

This NCore technology combines the stability of Hypex UcD series amplifiers with lower distortion and output impedance.

100% Aluminium Housing

We integrate this Hypex NCore NC122MP amplifier in a 100% black brushed aluminum housing.

This case offers an elegant finish, the thick walls give it a great resistance, allowing it to protect components properly.
The natural conduction of aluminium, together with a studied air flow, allows the heat produced by the module to be dissipated.
In addition, the case is screen printed on the front with the NCore logo and on the back with the nomenclature of each input/output.

Its very compact format with a small width reduces space to a minimum, thus offering high performance in a small space.

This amplifier is DC pass-through , there are no decoupling capacitors at the input.
Be sure that your source is DC free before use.
The DC protection triggers at 12V DC, which is a quite high value.

In addition to the usual connection system, there is a trigger input on the rear panel. 
This 3.5mm jack input allows the module to be switched on with a DC voltage signal from 5 to 12V to synchronize it with a preamp having this type of output.
It is also possible to chain 2 amplifiers, and to switch on both simultaneously by controlling only one, the input being transformed into an output if the power button of one of the amplifiers is pressed.

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



Also present on the front is a diode relaying the status of the module, lighting up if a DC voltage is detected at the output.

Commandé le dimanche et livré le mardi soir, parfait.
Ampli acheté pour driver des 'monitors' des 70's.....quelle claque !
J'ai eu une bi-amplification NAD qui ne lui arrivait pas à la cheville, que ce soit dans la faculté de gérer le HP de grave que dans la tenue des notes des medium/aigües.
Je suis maintenant dans la réécoute de mes meilleurs morceaux. De l'orgue au rock en passant par youn sun nah, rien que de l'exceptionnel.
Mes enceintes ont une impédance de 4 ohms, les 21 cms sont tenus, fermes, expressifs ( le bonheur ), alors que le reste du spectre est sensuel, précis, ciselé.
Je n'ai jamais entendu une différence telle sur un ampli.
Simple, de prix raisonnable, facilement logeable....Merci Audiophonics, vous m'avez redonné le sourire.

Parfait même pour enceintes paresseuses (84db) !
J'ai choisi ce 2x75W/8Ohm pour alimenter, en configuration bi-câblage, des Bowers & Wilkins 707 S3 à faible sensibilité (84db). La préamplification est confié à un FX-AUDIO Tube01. J'en ai également profité pour remplacer mes très vieux câbles d'enceintes et passer de 2x2mm2 à 2x2x4mm2 en ELBAC. J'ai souhaité optimiser et écouter différentes sources plusieurs semaines durant avant de poster mes avis sur ces matériels. La différence de rendu est toute à l'honneur de cette nouvelle configuration : l'ensemble du spectre sonore est devenu très intelligible, la dynamique est formidable et mon nouveau système se joue des fortissimo et grosses masses orchestrales ! Cet ampli de puissance joue parfaitement son rôle en restant très transparent et ne faiblissant en aucun cas. Je n'ai détecté pour ma part ni sifflante dans les aigues, ni "ploc" à la mise sous tension, ni quelque autre défaut que ce soit. C'est du tout bon, je recommande !

Good transparent and vivid amplifier
I bought the amplifier to replace my beloved Marantz PM-8005. Nowadays, I do not need most of the features that the integrated amplifier offers and I just wanted to have a simple amplifing block to link a Wiim Pro streamer (Tidal and Quobuz as sources), a Topping E30II DAC used as preamp and a pair of Dali Oberon 5. I had tried several cheap class D amplifiers in my secondary system and, although all of them performed well, I wanted to check whether Hypex Ncore modules made justice to their fame and measurements.
The amplifier arrived perfectly packed within a few days. 10/10 for Audiophonics! It is well built, robust and the connectors are also of really good quality. As expected, it is smaller and much lighter than my Marantz PM-8005 so it is a good alternative when espace is limited.
It has enough power to drive the Oberon 5 without problems and I have still quite a lot of margin using the volume control of the DAC to play to absurdly loud levels (definitely not healthy listening volumes). Regarding the sound (knowing is subjective and considering that I am by no means an audiofool), I have to admit that it is taking me a while to get used to it when compared to that of the PM-8005. I percieve a better detail, instrument separation and dynamics than in the Marantz, as well as better and cleaner bass control. However, I am missing certain soundstage and musicality or mellowness (some may call it distortion), which makes the PM-8005 a real pleasute to listen to in my system. I have the feelings that the Marantz is more forgiving with the quality of the source while, with the Ncore-based amp, poorly mastered records are almost inaudible.
All in all, really good option for reduce espaces or simple setups in which the conectivity of an standard integrated amplifier is not needed. Totally transparent, dynamic and with amazing bass resolution.

This amplifier sounds fantastic !
Having heard many different highend amplifiers the last 20 years, Im very impressed by the sound quality from this amplifier. It is very clean, neutral and powerful, and the spatial qualities and resolution are stellar.

The sound from this amplifier is an upgrade from the otherwise very good sounding Fosi V3 and Aiyima a07.
