Module unbalanced to balanced symetrizer JRC 4580DD BTL stereo
This audio module balances any HIFI-RCA-CINCH line-level asymmetric signal into a balanced-XLR signal independently and qualitatively. Equipped with quality passive components, the asymmetric input signal is processed by an JRC 4580DD per side on DIP 8 support. It is possible to replace the original PDOs with other models DIP 8 with pinout JRC 4580DD (eg OP2134 or NE5532).

This card is easily "tweakable" especially to replace the original capacitors by higher quality models. (Blue filter capacitors from 2200μF to 35V and yellow capacitors from 2.0μF)
It is suitable for the following assemblies and figures:
- Audio sources on CINCH-RCA analog output (CD players, BluRay, DAC) to studio and sound devices, eg mixing tables with balanced inputs.
- Home theater or HIFI preamplifier with RCA outputs to professional amplifiers with balanced XLR inputs.
- HIFI preamplifier with RCA outputs to HIFI High-End Audio amplifier high-end XLR balanced.
To operate, this module requires an AC 230 V to 15 V transformer. We recommend:

Super produit
Super rapport qualité prix.
Circuit imprimé et composant de qualité, bien monté. Audiophonics fourni trois connecteurs à visser pour les entrées sorties, on a donc le choix pour le câblage, super bonne idée, par contre pas d'entretoise ni visserie (un détail).
Les 5532 sont sur support j'ai fait des essais avec ces AOP et comparé avec des AOP 2134 il y a une légère amélioration mais rien d’impressionnant.
La carte est assez encombrante pas forcément facile à caser dans un boitier existant pour une réparation / mise à niveau.
