Audiophonics LPA-S500NC

Class D Stereo Amplifier Ncore NC502MP 2x500W 4 Ohm

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

The Audiophonics LPA-S500NC is a stereo amplifier based on an amplification module Hypex Ncore NC502MP. This solution is ideal for anyone who wants to have a large power reserve (2x500W) without sacrificing sound reproduction quality. This amplifier block is suitable for demanding speakers, it can be used to sonorize large listening rooms as well as studio applications requiring 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 limits signal interferences for cleaner audio output.

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.

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.

Connectivity


LPA-S500NC Amplifier has a 3-pole stereo XLR input on Neutrik NC3FAV2 sockets as well as a stereo RCA input on Elecaudio ER-106 sockets.

Bipolar selectors allow source selection and even allow independent control of the channels.

The amplifier output is made on Elecaudio BP-209 24k gold-plated speaker terminals. They can accept bare wires, banana plugs or even spades for quick and easy connections. 

A 5-12V trigger connector in 3.5mm Jack format allows to control the automatic powering of the amplifier when integrated in a compatible system. Finally, a bistable button allows the device to be switched on and off.

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

Phantastisch
Bestellvorgang und Lieferung ohne Probleme.Lediglich der Umkarton und die Freundlichkeit des DPD Mitarbeiters sind zu bemängeln,was aber nichts mit Audiophonics zu tun hat!Erster Eindruck ist großartig...solide Verarbeitung,problemlose Integration in mein Heimkino und eine Dynamik meiner Frontlautsprecher,die ich so noch nie gehört habe.Wie gesagt...erster Eindruck,aber voll umfänglich zufrieden!!!!

Excellent Amplificateur
Reçu en deux jours et super bien emballé. Merci Audiophonics.
Concernant l'ampli, il tourne depuis quelques heures et le son est déjà excellent. (Câblé en XLR)
Très beau boitier sobre comme j'aime.
Pas besoin de fioritures pour un ampli de puissance, car le son prime.
Je conseille vivement cet appareil.

An amazing piece of engineering
The built quality of this amplifier is top notch. I use it to power NS-10M‘s and it is exactly what I was looking for. Undetectable noise level, pristine audio quality and ample amounts of power.
What I love most about it is that there is absolutely zero mechanical (meaning: transmitted through the air) hum or buzz, what a revelation after years of having amps with humming transformers.
bon travail les gars, merci!
