Sound quality isn't great, the board is noisy
It has high noise, bluetooth stopped working quite soon after the purchase (2018), loud crosstalk from line input while bluetooth and so on. Cannot use with all the attachments, like Jab3 and batter pack because they utilize same connector. It is feature packed product with great expectations, but a disappointment and would not recommend purchasing this product. While it works, it is cumbersome and just poor quality.

That said, purchased it 2018 and now 5 years later it still works apart from the bluetooth so in this sense it's fine. Just do not expect anything from such cheaply made product.

Très correct pour le prix
Bien fini, plug and play, rien a faire a part brancher et écouter. Pas de bruit parasite pour la part mais le son n'est pas non plus exceptionnel. Je l'ai installé dans une radio année 50 en remplacement du système d'origine. Cela suffit amplement pour l'usage dédié (écoute en volume modéré dans un bureau). Couplé a une alim 19v et des HP alpine 4ohm.

Boombox qui renaît de ces cendres
Idéal pour moderniser une Boombox des années 90 sortie du grenier avec remplacement des Hp par des Focal ISS. C'est pas compliqué, tu branches, ça marche. Aucun problème pour ma part.

Très bon produit
Pas de souffle de mon côté (utilisation bluetooth avec iphone SE et ipad air), son très correct et suffisamment puissant, en tout cas suffisant pour moi (transformation TSF en HP bluetooth). Livré avec cable mono HP mais sortie dispo pour stereo.
A associer avec panneau de contrôle Dayton.
Bravo pour la disponibilité et la reactivité de l’equipe Audiophonics.

Parasites
Exactement le meme parcours que Stephane, des gros parasites, souffles et meme un beat étrange. Testé avec plusieurs alim, impossible de trouver la cause.

Super SAV, très cordial et réactif. J'ai renvoyé le produit.
