PRE-AMPLIFIER VOLUME CONTROLLER SOURCE SELECTOR

Double class A linear power supply, 4x RCA inputs, volume control, 3x equalization bands, 4x AOP LME49710




This carefully designed preamplifier and source selector (4 inputs) has two separate circuits for each channel of the stereophonic signal. Each of these circuits operates in pure class A and is powered by its own regulated linear power supply to provide extremely clean channel separation and preserve the signal finesse. Each channel is controlled by two operational amplifiers LME49710.

Class A preamplifier


The PRE-BD1404CH has an elaborate preamplification circuit with separate preamplified channels and separate power supplies. It offers volume control via a rotary potentiometer located on its front panel.

It also offers a three-band equalizer (Bass / Medium / Treble) to enable minor tone adjustments to find a pleasant balance depending on the specifictions of your analog audio installation.

A selector located on the front panel allows to completely bypass the tonal adjustment function in order to keep only the unprocessed signal in the preamplification circuit. A diode indicates the bypass status.

Source selection

In addition to its preamplification / volume control / three-band equalizer function, the PRE-BD1404CH offers a source selection function on its 4 stereophonic inputs (RCA connectors). The output connectors are mounted on its rear panel.

The stereo output, also on an RCA connector, is located on the same panel to allow clean and ordered wiring.

Finally the rear panel has a power connector (IEC) made for 220V voltages.

The source selection is made using a rotary selector located on the front of the device.

AUDIOPHONICS PRE-BD1404CH
Acheté comme selecteur de sources , la fonction preampli est un plus avec les reglages basses /mediums/aigues et ou bypass .
Je trouve ce preampli très detaillé peut être un peu trop à mon goût avec mon ampli nc 250 ,enceintes magnat transpuls 1500 et ma source nvidia shield.

Je lui reproche un selecteur de sources et des potentiomètres sans graduations et 2 voyants rouge aveuglants.

Malgres cela , son prix vaut le détour et peu faire des heureux assurément!

Bon MAIS pas de cable d’alimentation!!
Bonne qualité de construction. Malheureusement, il était livré sans câble d'alimentation ! Je ne sais pas si c'est une erreur ou si c'est normal. Le préampli sonne bien. Il y a un peu de sifflement du préampli mais rien de plus. Il y a un clic d'interrupteur à l'allumage et beaucoup de bruit après l'extinction. Les contrôles de tonalité sont plus subtils que ce à quoi je m'attendais et j'aime ça. Dans l'ensemble, c'est un bon rapport qualité-prix et bien plus que ce que l'on peut espérer pour ce prix.

préampli Riaa
Bonjour, je voulais savoir si toutes les entrées sont identiques ou si l'une d'entre elles possède un préampli Riaa afin de brancher une patine vinyle...
Merci

Très bon préamplificateur, bien construit et de qualité.
La qualité sonore est au rendez vous. Son clair, précis et détaillé. La restitution du bas registre est excellente. La séparation des canneaux se fait bien sentir, tout est sa place lors de l'écoute.
Les moins sont comme dans un autre commentaire, les lampes rouges interne qui ne servent pas à grand chose.
Moins convaincu par la section de correction de tonalité. En mode réglage de tonalité, pour ma part, je perd en qualité sonnnore, dynamique, et gain. Le son est moins naturel.
Assemblé avec mon ampli à lampe TAC,34 et mes enceintes wharfedale e50 en mode bypass, c'est un véritable régal auditif.
Satisfaction garantie avec ce petit preamplificateur dont le rapport qualité prix est bien plus que correct.
A recommender.

Surprisingly-capable detailed, dynamic, spacious, full-range sound
Not a preamp for purists or price-deluded elitists. Their loss. Featuring full dual-mono design, shunt-regulated DC, dual-stage opamp gain, relayed input switching and tri-band equalizer (!), this Chinese product offers great value for money. A most pleasant surprise.
