Audiophonics MPA-S250NC XLR

Class D Stereo Amplifier Ncore 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.

So Far So Good!
I am from the US (east coast). Ordered on a Wednesday (before 11 am UTC) and got it Friday morning!!! Unbelievable delivery speed!!! Ordered some cables at the same time from Amazon (I have Prime) and got them Saturday...
Regarding the amplifier, too soon to tell, but so far it's working great. Amazing audio and excellent built quality! Congratulations AudioPhonics!

Cleanness and transparent sound with power
This is the first time I ordered this Hypex module based amplifier of Audiophonics and I don't regret it. It arrived into to a luxurious home's audiophile system and the owner (a friend of mine) was blown away by the quality and cleanness of sound. Excellent product, thank you Hypex, thank you Audiophonics.

Superb power amplifier
Small box but really big sound. It has plenty of power and great control. In my music system it works with Atoll CD100SE2, Audio GD NFB 1 AMP and Paradigm SE3. I am really satisfied with the sound.
AUDIOPHONICS MPA-S250NC XLR has my strong recommendation!

Great amplifier for the price
I was convinced of getting a Hypex nCore NC252Mp after reading the review of Archimago about it and the reviews on Audio Science Review of the hypex ncore amp. Audiophonics provided the a great build and less expensive in comparison with builds by other companies.

They power the Elac DBR-62 in my system. I cannot hear any noise coming from it, not even when I put my ear against it. It's also just slightly warm and doesn't seem to run hot.

The only things that is not clear from the pictures is how large this thing is. it's length is close to the height of the DBR-62. And from what I've seen of people who opened it, there's mostly open space in there.

Can something be done to make this more compact without sacrificing anything? I hope they consider this for future products.
