Audiophonics HPA-S500NC

Class D Amplifier 2x NCORE NC500MP 500W RCA balanced XLR

PA-S500NC Audiophonics

The HPA-S500NC is a :massive stereo amplifier. It was designed to meet power and precision requirements.

Based on a duo of Hypex NCORE NC500MP OEM modules, this class D amplifier has tremendous efficiency thanks to two switching power supply units with synchronous control.

As most of the amplifiers based on NCore, the frequency response is independent of the load and EMI are well cancelled, which significantly limits the overall distortion.

 The HPA-S500NC will be particularly appreciated in all situations requiring high power amplification while maintaining a high signal neutrality. It will fit in both a professional studio or a private home.

Two modules NC500MP

assembled NC500MP power amplifier

Each channel has its own 500W high efficiency amplifier circuit; low output impedance, low distortion and low noise.

Each circuit has an independent power supply, which refines the sound stage and to preserve the dynamic without causing additional distortion.

All internal connections uses OCC 2.5mm² wiring to enjoy excellent conductivity and preserve all of the subtleties of the signal.

RCA jack and XLR power amplifier

RCA and XLR switchable inputs

The power amplifier has two RCA (stereo) input ports and two XLR ports (balanced stereo).

The RCA sockets are gold plated 24k with plastic heat-resistant capsule.

XLR connectors are high quality Neutrik connectors with metal latch and gold-plated drivers .

A two position switch allows the user to toggle between the XLR and RCA input with ease. It it thus possible to connect two different preamps and alternate input sources.

High quality terminals compliant with banana plugs

On its rear side, the PA S500NC has two pairs of 24k gold-plated speaker terminals.

These terminals are designed to accept banana plugs up to ⌀4mm.

They can also host ⌀5.3mm bare wires with a screw lock.

Power amplifier 2x500W 12V Trigger

5-12V trigger

A trigger socket brings the comfort of an ignition sequence and allows a complete integration into a well-developped audio system.

The power input is a IEC14 socket with gold-plated copper conductors. The latter works with a 5x20mm fuse 3.150A (supplied and already mounted).

Heat dissipation

Because it is able to output considerable power, the HPA-S500NC will be subject to thermal stress during use. The heat management is a key issue to achieve a high level of sonic accuracy and keep distortion under a determined threshold.

For this reason, each amplification module is mounted on a large heat radiator which is capable of effectively dissipating the heat. Similarly, ventilation holes distributed carefully will promote air circulation and heat dissipation.

C est une bombe !!!
J'avais commandé son petit frère un peu juste pour les FOCAL ARIA 948.
Celui ci est juste magnifique
Mais alors MA- GNI- FIQUE
Des potes a moi travaillent chez Focal a st etienne m ont recommandé Audiophonics. J avoue qu au debut je n y croyais pas et voulait me tourner vers Rotel ou chose comme ça mais alors je conseil à mon tour.
Merci Audiophonics

l'ampli est couplé avec un DAC TOPPING DX7s 2xES9038Q2M que j'utilise aussi comme préampli. , relier a des cabasses Iroise MC de la grande époque de George Cabasse, et ma source un raspberry et aussi un Récepteur audio Bluetooth 5.0 AptX HD CSR8675 vers SPDIF.

Le son est très bon, vraiment naturel, avec de l'énergie, aucune agressivité. les basses sont très musical, le médium est ouvert et chaleureux, les voix sont belle (Diana Krall, Dire Straits, Anne Bisson..) et les instruments à corde et les instruments à vent sont bluffants, organiques, bien timbrés, expressifs.

je suis monté en gamme au niveau du câblage entre les maillons et à chaque fois c'est un apport qualitatif (parfois surprenant) sur le rendu global de l'écoute.

merci Audiophonics pour leur contribution à proposer des produits excellents à petit prix !!!

Ncore à bon prix
Parfait, que demander de plus?
Très content de cette amplis, le boîtier à une bonne gueule, solide, diffuse bien la chaleur. logo Ncore à droite, Audiophonics à gauche, pas de souffle.

la mejor etapa de mi vida
He tenido hibridas clase A, valvulas, Emotiva, pero esta Audiophonics Hypex Ncore basada en NC500MP doble monofonica se las come a todas con un previo pasivo a transformadores, cajas Focal o Dynaudio, fuente Arcam y cableado todo en cobre chapado en plata. Lo que decian en los foros de la ncore era como lo que decian de los previos TVC, todo verdad!
Limpieza, potencia, detalle... estoy asimilandolo aun no me lo creo
