Class D Stereo Amplifier Ncore 2x250W 4 Ohm

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

The Audiophonics MPA-S250NC RCA 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 stereo unbalanced RCA input with gold-plated connectors. 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.

Great Sound and Powerful AMP
The performance of this Hyper NCore AMP is great.
The 4ohm and 2ohm output is powerful to use on speaker with min ohm as low as 3ohm.
The sound is transparent and no extra added.
The build quality is good and they are kind enough to send me the UK plug power cable in the package, which is a nice touch!
Although the front panel is a little too Bright but it is ok to and not affecting you to enjoy your music.
I am already planning to add a mono for my center channel and maybe even more to power the surround speakers!
Highly suggest anyone who is finding a class d amp at a reasonable price, you won’t regret this purchase!

NCore bargain
Great amp, great price. Audiophonics have built a quality product, looks great, sounds better. I challenge you to find a better spec'd Ncore 250W/c class D for $600AUD. Be prepared to wait a little for delivery - good things come to those who wait.

Super amplifier.
I had been searching for a long time to find an amplifier with Hypex modules. The Audiophonics MPA-S250NC was my perfect fit for a very good price.
I wasn't satisfied with the sound of my system and I thought it was because of the quality of my speakers(Millon Phantom-S).
Now that I replaced my Yamaha amplifier with the MPA-S250NC the speakers sound so much better.
I didn't expect an amplifier to give such an improvement.
The trigger input to power on the amplifier from my pre-amplifier is also a very welcome option.
Delivery to The Netherlands within 3 days for a reasonable price is also perfect.
So, nothing to complain!!

superbe ampli de puissance !!!
J'ai fait l'achat de cet ampli après renseignements et avis divers..donc un peu à l'aveugle en fait...eh bien...franchement pas du tout déçu, je suis enchanté par le rendu de cet ampli. Tout est plus clair et détaillé.
le tout reste très dynamique sans tassement. il est en amont d'un NAD D3020 V2 et une paire de Davis Olympia one master...c'est vraiment beau et d'une douceur incroyable, les médums sont magnifiques , les graves fermes, et les aigus précis. cet ampli devrait couter plus cher...mais tant mieux pour nous....il reste très abordable et on rentre de pleins pieds dans la haute fidélité . Bravo Audiophonics !!!!!

Does exactly what you expect!
Using this to power my front Elac DBR-62 speakers (which are in a 5.1 setup) pre-out from Denon AVR-X3600h. Can I tell an immediate difference and upgrade from the Denon at the average listening levels I typically enjoy? No. Does it still sound great? Yes! So why bother? Well, I was mainly curious and wanted absolute assurance my speakers were being driven properly by an amp.

Chances are that unless you have a bad amplifier, or are asking a lot of your AVR (powering 7+ speakers at loud volumes) that can't really drive your speakers then you won't hear much of a difference, like in my scenario. It's a transparent power amplifier that will allow you to go to really high volume levels and supply the power you require for speakers that may demand more. It's a good product for doing this in a relatively small enclosure, it feels solid, and I expect to not need to upgrade again for a long long time.

It gets about as warm as my Denon so make sure you have some room for it to breath. Originally I put it in a drawer in my unit but after approximately 90mins of moderate usage I rechecked the heat and it was quite warm so I moved it outside of the drawer as a precaution.

I'm happy and received the product in 4 working days (ordered Thursday morning, here Tuesday morning) through TNT tracking which was great.
