Man muss den Vertärker ggf. mit Ferritperlen oder einem RC-Glied bedämpfen. Leider ist kein Schaltplan dabei. Die Endstufe ist in Gegentakt-Brückenschaltung (H-Brücke) ausgeführt, deswegen dürfen die Lautsprecher/Kopfhörer NICHT einseitig an Masse liegen oder eine gemeinsame Rückleitung haben! ### ⭐⭐ Leider defekt, sonst scheinbar guter Verstärker *by J***L on Reviewed in Germany on 28 April 2016* Ich habe mir den Verstärker gekauft um ihn als Vorverstärkung für meine E-Gitarre zu nutzen. Da das Breakoutboard durch Einfachheit besticht hab ich mich für dieses Bauteil entschieden.Lieferung, Verpackung war alles in Ordnung. Leider musste ich feststellen, dass das Breakoutboard leider defekt ist (oder ich bin tatsächlich zu blöd es anzuschließen). Wenn ich Versorgungsspannung (von verschiedenen Netzteilen) anlege bekomme ich immer nur ganz komisches Rauschen. Das Signal rauscht in 500mv-1V-Bereich mit regelmäßigen Peaks die bis an die 5V Versorgungsspannung hochgehen. Wenn ich am Eingang audio anlege (egal ob Gitarre oder MP3player) ändert sich am Ausgang garnichts.Wenn ich den Sw-Kontakt mit dem zugehörigen Ground kurzschließe ist das Ausgangssignal nahezu null, dieser Teil funktioniert also. Jedoch kann ich den Chip nicht wirklich verwenden.Nachdem ich jedoch einige Youtubevideos gesehen hab scheint der Verstärker (wenn er funktioniert) doch einen recht guten Sound zu liefern, daher 2 Sterne. Man sollte vielleicht gleich 2 Bestellen, bei dem Preis ja auch kein Problem. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/129934593-foxnovo-high-power-super-mini-digital-audio-amplifier-board-board](https://www.desertcart.tn/products/129934593-foxnovo-high-power-super-mini-digital-audio-amplifier-board-board) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
