Sehr kleiner gut funktionierender Audio-Verstärker. Zweite Lieferung defekt, dritte Lieferung o.k.
Der erste gekaufte Verstärker hat super funktioniert. Deswegen habe ich noch einen Zweiten gekauft, eingebaut in eine Lautsprecherbox. Der kam gleich erst einmal zertrümmert bei mir an, siehe Bilder. Eine Ferritdrossel ist zersplittert, der neben der Drossel angeordnete Elko ist halb herausgerissen und steht schief. Hier muss es massive Gewaltanwendung beim Hersteller gegeben haben, weil die gesamte Verpackung völlig in Ordnung war. Es handelt sich nicht um einen Transportschaden, traurig. Diese Sendung geht umgehend zurück. Die Ersatzlieferung war nun wieder in Ordnung. Das ist ein sehr gut funktionierender Verstärker. Ohne Ansteuerung gibt es absolut keine Fremdgeräusche, Rauschen oder Brummen. Einziger Nachteil: Wenn ein Klinkenstecker eingesteckt wird muss Bluetooth über den kleinen Leiterplattentaster aktiviert werden. Wenn kein Stecker eingesteckt wird läuft über Bluetooth alles automatisch. Prima Teil um aus normalen Lautsprechern Aktivlautsprechrr zu machen.

Perfect for making your speaker active
Not sure why it is so cheap but does a great job on my little hifi speakers running at 12v with a spare power supply that I had. Stuck it on with double sided tape and have a decent pair of active speakers. Bluetooth connects really well with no problems. I recommend setting the volume on the device lower and then using the volume on the laptop but you can play around with both levels to see what works best.

Very Satisfied
Update 9/12/2022 The original unit purchased 8/5/2020 still works great. No problems at all. It works so well I bought a second unit this summer for our summer place. It also works great. Original review: It does everything it says. The sound is crystal clear and way loud enough to hear outside on our deck with two Yamaha 8 Ohm speakers on a busy street. I connect to the unit via blue tooth from my phone. So far, it's connected each time since the initial pairing without a problem. I do power the unit down when not in use. When powered up, it beeps first to says it's up, then a second time when it makes the blue tooth connection. I have not attempted to push the sound up as high as it can go as I'm sure my neighbors would not appreciate it. :) I have recommended this to others. I can't say anything about quality or longevity as I've only had it installed for a few weeks now.
