Audiophonics LPA-S600NCX

Power amplifier NCore NCx500 2x600W 4 Ohm

Audiophonics LPA-S400ET Amplificateur de puissance PURIFI 2x400W 4 Ohm

We are proud to present the Audiophonics LPA-S600NCX, a Class D stereo power amplifier based on two NCore NCx500 modules. Electronically similar to the HPA-S600NCX, this version is housed in a more compact enclosure, making it easier to use in environments where space is at a premium. Its architecture also limits the length of the internal connections.

This ready-to-use, pre-assembled model is aimed at audiophiles looking for a foolproof amplification solution with a considerable power reserve and impeccable definition. NCore modules are among the most rigorous Class D amplification solutions on the market, with simply exceptional measured performance.

The whole package delivers a high level of sound reproduction, ideal for use with demanding loudspeakers, in large listening rooms or in studio applications requiring considerable headroom without compromising on the precision and richness of the audio message.

All the components are housed in a sober, robust, stylish and compact 100% aluminium enclosure. The enclosure has apertures to promote heat dissipation. Its design also limits the impact of interference on the signal.

Two NCx500 OEM mono modules


Each channel of the Audiophonics LPA-S600NCX features its own Hypex NCore NCx500 amplification circuit with high efficiency and low output impedance, distortion and noise. This new module has greatly improved performance in terms of distortion and output impedance. Each amplifier module is capable of delivering 700W of power at 1% THD. The integrated 1200W HYPEX power supply enables them to simultaneously deliver 600W at 0.01% THD into 4Ω.

Particular care has been taken with the internal wiring and assembly of the amplifier, using large-section power supply wires, Canare input signal cables and PTFE-insulated speaker cables.

Hypex SMPS1200A700 Power supply module

The SMPS1200 switching power supply is a very high efficiency model capable of developing a rated power of 1200 Watts in an extremely small footprint. It has been specifically designed and developed by Hypex to supply the 2x85V voltage required to operate the most demanding amplifier modules.

This high-quality, low-noise power supply meets the power requirements of the amplifier modules in every respect. What's more, the modules themselves have an excellent ability to reject power supply noise. As a result, the LPA-S600NCX is extremely insensitive to imperfections in the electrical network and to voltage/current variations that can cause parasitic noise.

Audiophonics interface board

The 2 modules are controlled in phase opposition, to cancel the "Power-Supply Pumping" effect. This makes the power supply more stable, distributing the current draw alternately on each rail, thereby increasing its capacity.

We opted for 2-level voltage regulation, to optimise the power supply to the AOPs and the auxiliary voltage supplied to the modules.

One Texas Instrument LM4562 PDU is used per channel. These are very low distortion PDUs offering the greatest transparency with very low THD. They are mounted on a DIP8 socket, allowing them to be replaced if necessary.

To suit all applications, we have opted for 5 gain settings, switchable via jumper on the underside of the unit :

  • Gain of a total of 19dB - Maximum power reached with a 5.33V RMS signal.
  • Gain of a total of 25dB (default) - Maximum power reached with a signal of 2.67V RMS.
  • Total gain of 31dB - Maximum power reached with a signal of 1.5Vrms
  • Total gain of 33dB - Maximum power reached with a signal of 1.2Vrms
  • Bypass (buffer deactivated): In this case, the signal passes directly from the inputs to the modules, allowing the lowest possible gain of 12.5dB. This mode can be interesting when using a powerful preamplifier, capable of driving a load of 2 to 4K Ohm and reaching a voltage of 10V RMS.

Connectivity

Designed for easy integration, the LPA-S600NCX has both balanced (XLR) and unbalanced (RCA) stereo inputs. Bipolar selectors make it easy to change input sources and even allow independent control of channels.

On the output side, BP-207 carbon / 24k gold insulated terminals (Ø5.5mm) provide an excellent connection to loudspeakers.

Outstanding!
One piece of advice: give this little guy some time to break in, at least 20-30 h, after that you will enjoy exactly what is recorded in your cd, lp, file or whatever, no more no less. This amp is the most neutral and transparent I have ever heard so far; it does not sound at all, it just amplifies what musical signal it is fed, adding nothing, taking nothing. This can be a little baffling and take your ears a bit of adjusting, because other amps in comparison (way more expensive I have to say) "sound" thick, fat or shrill or harsh, in a word coloured, which many easily mistake for "good sound". And the power! Effortless power! I had no idea that my speakers had such a powerful, deep and controlled bass before. In my humble opinion, this little beast is simply the best amp I have ever heard and a real steal for the money. Thank you Audiophonics for the excellent service!

Hands down the best amp there is.

The price.
The NCX-Performance
Clean 600 Watt RMS
Adjustable gain to fit any preamp
RCA and XLR switch without any ground loops.

This amp from Audiphonics is objectively the best there is where the stars align in terms of part, design and quality.

The ultimate bonus: About any parts can be replaced by yourself. It's a no brainer.

Just buy it already and don't look back :).

Dynamics and Control !
A power amplifier with fantastic dynamics and control. My previous power amp was 1st generation class D (ICE Power) and development has really progressed since then with these Hypex NCx500 modules.
Can really recommend this power amplifier which, in Audiophonic's design, is of top quality at a reasonable cost.
The purchase process was without problems with fast delivery.
