Preamplifier volume controller source Selector

Preamplifier Class A / Potentiometer ALPS / LM337 / 7812CT / CMC816

Amplificateur_class_a_audiophonics_4l.jp

Here a precise and compact preamplifier equipped with a source selection function (three inputs) and an analog volume control. It operates in class A for clear and transparent sound reproduction with minimal signal coloring. A linear regulated power supply with R-core transformer make a reliable device, responsive to the specifications to fit both in an advanced system that in a small and compact system.

Discrete output stage

Typical circuit HDMA Hyper Dynamic Amplifier Module


Amplification of the signal is designed in discrete component With its gain stage directly integrated to the PCB.

Thanks to a design based on a standard architecture HDAM this circuit enjoy superior insulation and very low latency in the voltage rise. It thus provides excellent dynamic reproduction while maintaining noise below a very low threshold.

Source selector

A rotary knob 4 position immediately toggles between three different sources. This preamplifier is able to combine several sources (PC-DAC, phono preamplifier, integrated network drive ...) and switch from one to the other without changing connections.
The fourth and final position of the rotary knob (counterclockwise) allows to transfer the input signal without disrupting the volume or turn off the device.

To avoid any confusion or accident in the connection of different input devices, marking each position is found at the back of the housing at the corresponding RCA inputs.

All RCA connectors are gold plated 24k CMC816 model for a very respectful maximum conductivity of the audio signal.

Volume Control

This preamplifier has an analog volume control based on a potentiometer ALPS.

The volume can thus be easily controlled via a knob on the front.

This stereo fader follows a logarithmic dimming curve that will work well with equipment sensitive to slight variations as with demanding installations requiring high volumes.

Rcore transformer linear power supply preamp class A

R-core transformer


This preamplifier operates a Class A power supply for rendering a transparent sound which remains rich in detail. This power supply is centered around an R-core transformer, a linear voltage regulator 7812CT as well as Nover capacitors.

This type of configuration positively affects the sound quality of an audio installation as a whole while emphasizing the technical qualities of the audio / DAC before it.

Each controller is respectively mounted on a radiator and is accompanied ELNA capacitors and WIMA film capacitors in order to maintain the balance and overall stability in the process of preamplification.

The diode bridge uses resistors 718 Beijing having excellent heat resistance and superior accuracy.

Excellent préampli
Sans parler du rapport qualité-prix tout simplement bluffant, c'est dans l'absolu un excellent préampli, sans coloration particulière, mais d'une grande musicalité, et d'un grand silence de fonctionnement.
On l'oublie au profit de la musique, et c'est une qualité.
Il lui faut toutefois une bonne douzaine d'heures de rodage, au début l'image sonore paraît assez plate.
Et je pense qu'il va encore s'améliorer avec le temps.
Belle qualité de fabrication, du sérieux.

Exceptionnel pour le prix
Une fois testé et choisi le bon cable de modulation surtout
en amont de ce préampli, ce préampli délivre un un rendu sonore exceptionnel pour son prix.
Ce rendu combine une certaine douceur, c'est vrai, un grand confort d'écoute mais aussi une transparence étonnante, une matière très agréable et des timbres d'une grande justesse. La dynamique n'est pas oubliée mais comme le reste, le naturel prime et la stricte analyse fait place bien heureusement au plaisir de l'écoute, qui est grand. Du délié, de la souplesse, j'aime beaucoup...
Par sa petite taille ce préampli est trés agréable dans la pratique, les prises sont d'une grande qualité, les commandes respirent le sérieux. Ce préampli présente une bonne marge de progression en jouant sur les cables, la nature des supports et éventuellement en mettant des pointes, mais les pieds d'origine sont excellents.

good for the price, not totally transparant
Good for the price, but if you want total transparency, go for a more expensive preamplifier (this one makes the sound softer and a bit less detailed)

Rapport qualité prix au RDV
Merci à AUDIOPHONICS pour la rapidité du suivi de la commande et de la livraison.
Audiophile non spécialiste, je suis très satisfait de ce préampli des plus simple à utiliser à un tarif attractif. Sa capacité à se faire oublier me semble être une de ses qualités. Douceur et clarté sonore sont bien présentes. Remplace avantageusement un ancien Advance acoustic MPP206 notamment pour le réglage du volume beaucoup linéaire et progressif. Les possibilités de connexion se limitent par contre à 3 sources d'où 4 étoiles.
