DollaTek ZK-502M Audio Mini 2.0 Stereo 50 W+50 W bluetooth Digitale Versterker Module 50 W* 2 AMP Amplificador Home Theater AUX USB

Superhandig klein dingetje, wel even zelf inelkaar zetten. Erg handig dat hij verschillende voltages als voeding kan hebben. Ik gebruik hem om mijn studio speakers aan te sluiten op mijn PC. Daarvoor werkt dit versterkertje perfect.

Nice while it lasted but stopped working all of a sudden.

Fonctionne bien, remplace un ampli pour un PC.

No instructions but didn't take long to work it all out. The heatsink doesn't stick very well. Powering it with a 24v 5a LED brick (photo attached, cabling is short as it was just a test). Neighbours probably not impressed after I gave it a good slog with some drum n bass... But hey, that's life!Noticeably louder than my other supposed 100w amp but also noticeably not as smooth sound-wise. A bit too much midrange but if you got an EQ you'll be tweaking it. My Akai speakers aren't exactly Bose.There's some stupid voice when you switch it on. The blue light on mine constantly flashes (I was running it through the audio socket to my smartphone, rather than the bluetooth) and I would recommend you turn the volume to minimum when you power it on or off. I had a rather loud click through the speakers.For this price, it's hard to complain about the negatives. I'm going to give it full marks despite all the quirks listed above. Dollatek, take note: Get rid of that stupid voice on startup and the flashing blue light and you've got a cheap and very cheerful amplifier.

Was not expecting that high quality and volume for that size and price. Playing it with bookshelve speakers and a 12v 2amp power cord I had lying around.If you are looking for a small and cheap amp, here you go!!!

No trae instrucciones de ninún tipo, aunque su montaje no tiene mucho misterio. Se monta en 5 minutos (te has de fijar en las fotos del producto para ver dónde va colocado el disipador de calor, una vez lo tienes claro, le retiras el film protector de la base y lo pegas al circuito integrado.Tiene una cubierta para la parte de abajo y otra serigrafiada para la parte de arriba, como digo, su montaje no tiene complicación.Lo más débil es el botoncito de encendido, veremos cuánto dura.Al encenderlo detecta si tienes algún cable de entrada enchufado (AUX-IN o USB), y se pone automáticamente en el modo de la entrada que detecta (lo dice por los altavoces en inglés)Si no le conectas cables de entrada de señal, se pone automáticamente en modo bluetooth y se enlaza sin problemas con cualquier cosa (lo encontrarás como "Wuzhi Audio")Suena increiblemente bien para el tamaño que tiene, con unos graves bastante contundentes. En modo bluetooth no he notado retardo entre el video de una película y el audio.
