DollaTek 50wx2 mini bluetooth 5.0 wireless audio power digital amplifier board stereo amp 3.5mm aux usb

I had an old centre speaker that I wanted to make use of in my work shop ... took a gamble and WOW what a super little amp Needed a 12v supply but will up to 24v eventually sound is great no back ground noise and no hiss .. easy set up all instruction are on the seller page . Any one that moans about fitting the cover needs to have a rethink on value for money . 10 quid for an amp this good is worth every penny I added a small active sub using the headphone 3.5 jack for bit more bass Works without issue . Overall really happy with quality of Bluetooth and sound quality

I bought this so I could stream music from my phone to a pair of old speakers in my shed. Connected it up to a 12V power supply from an old laptop and it just worked straight away. How can something so small and inexpensive just work so well? I've now ordered another one to use in my home office. Highly recommended!

Used to convert an old Philips centre speaker into a portable bluetooth boombox. Took less than 5 minutes to put together and wire up. Works with anything from 12V up to 24V psu, and even powered it with a portable phone battery and a 5V to 12V boost cable (£7 on here). Excellent value for money.

For the money this is an incredibly feature-filled and well-made little device. I like the encoder-based digital volume control and the USB-C connector is welcome (rather than Mini/Micro USB). It doesn't appear to have any obnoxious spoken paring/playback status reports with the bluetooth mode either, which is common on the cheap bluetooth boards. However there is a very loud background hiss (with all of the inputs). I tired a number of suitable high-quality power supplies within the claimed voltage range with no impact on this noise. This isn't audible when nothing is playing, because the amplifier appears to be automatically deactivated when the device is idle. However there is a short lag when audio stops before the amplifier is turned off, making it briefly very obvious. This noise *is* audible during quieter sections of music. You could say this is forgivable for the price, but I have other cheap dac/amps in the same class with no audible background hiss.

This comes as a kit, which some might see as a negative but I enjoyed screwing it all together. Really impressed at how much functionality it has, and had no problem powering the speakers I plugged in. With a wide voltage range you can pretty much put any power supply on it. Tempted to buy a second one...

OK, firstly THESE AMPS WORK. I’m not interested in 1 star reviews that say otherwise. Pros: Runs off DC voltage from between 5v to 24v (not mains directly). The higher the voltage, the better the amp will work. 3.5mm jack socket for audio line in USB ‘C’ socket Left and right speaker output connections Headphone/ear buds output socket On/off switch via main control knob (Press down for 2 seconds to switch amp off) Power indicator light Good sound output for the price, neatly fits into a small space, worth the money. Cons: Some self construction required but no soldering. Small screwdriver supplied. Due to the small size of the amp I found some parts a bit fiddly when constructing. No instructions (refer to pictures in product description on Amazon website) Note: The connection polarity is important from your power supply. If the amp will not power up, try swapping the +/- polarity. I connected mine to the line out from my suitcase vinyl record player because the built in amp is crap. This little amp is now driving 2 x 75 watt Wharfedale Modus speakers and sounds great. I’m pleased with this purchase.

The amp is quiet, load of background noise, no bass and to top it up if you want to use the Bluetooth functionality you will need to download an app. Truly terrible, do not recommend

I got this to use with a Bluetooth turntable (audio-technica Sound Burger) that has no volume controls, to connect wirelessly to my active portable speaker (minirig) which also has no volume controls. I'm powering it with the usb charging cable (they both use same round pin connector) that came with the minirig speaker plugged into an old 5v Amazon usb plug that came with a firestick. Does the job perfectly. Bluetooth connects easily and it sounds fantastic! 5v is enough when using active speakers. The online manual does state that the audio out jack is for active speakers with built in amp. So although there is a headphone symbol next to the audio out jack, don't bother using this output with regular wired headphones as my senheizer ones sounded quiet with no base or middle. There are connections to wire two passive speakers up to 50w each as shown in the picture I've attached but you will have to increase the voltage of your power supply depending on the wattage of your speakers. Overall I'm impressed with the performance.

Estaba desesperado con el pésimo sonido de mi televisor de pantalla plana. Los altavoces eran de bajísima potencia, se escuchaban fatal e incluso estaban ya cascados. Ver películas o escuchar música a través de mi viejo lector de DVD conectado a la TV era una tortura para mis oídos. Estuve a punto de comprar una barra de sonido, pero las opciones que realmente valían la pena se escapaban de mi presupuesto, y las más baratas no terminaban de convencerme. Recordé que tenía guardados unos altavoces pasivos de un equipo de música antiguo que se había estropeado. También, como buen "acumulador" de gadgets, tenía por ahí en una caja varios cables y adaptadores que había rescatado de otros aparatos, incluyendo un adaptador de corriente de 12V (¡importante, porque este amplificador no lo incluye!). Entonces, ya lo tenía claro: ¡solo necesitaba un amplificador! Y ahí es donde entra este pequeño(cabe en el bolsillo, lo cual para mí es un plus) pero poderoso amplificador DollaTek 50W x 2 Mini Bluetooth 5.0. Por el increíble precio de 11,99€, decidí darle una oportunidad, ¡y ha sido la mejor inversión en mucho tiempo! Ahora, tengo un verdadero "cine en casa" y un equipo de música funcional. La diferencia en la calidad del sonido es abismal, ¡un 200% mejor de lo que tenía antes! Estoy realmente encantado con el resultado. Es cierto que no viene con instrucciones impresas y tendrás que montarlo tú mismo (conectar los cables de los altavoces y la fuente de audio). Pero hoy en día, con la cantidad de vídeos y tutoriales que hay en YouTube o plataformas similares, esto no es ningún problema. Encontrarás fácilmente guías para conectar un amplificador de este tipo. En resumen, si tienes unos altavoces pasivos por casa y estás harto del sonido deficiente de tu TV, no dudes en probar este amplificador DollaTek. Por un precio irrisorio, transformarás tu experiencia audiovisual. ¡Altamente recomendado!

Eines meiner Hobbys ist HiFi. Ab und an muss ich neue Geräte ausprobieren. Jetzt hab ich mich mal umgeschaut, was es im absoluten low budget Bereich gibt. Dieser Verstärker ist unfassbar gut. Mit einem kräftigen Netzteil betrieben, hängt er von der Leistung und Dynamik her jedes Mittelklasse-Gerät mit derselben Leistung spielend ab. Selbst Partylautstärke, kein Problem. Für Selbstbauprojekte der optimale Spielpartner. Ich bin überrascht, was es schon für 10 € zu kaufen gibt. Von mir ganz klar, 5 von 5 Punkten!

For anyone saying there is no indicator light, yeah.. there is... it's blue, it lights up as soon as it has power... if you connect it to a stereo jack, the bluetooth turns off, if you unplug stereo jack, bluetooth is back on... does not need the app... If there isn't a power light, hold down the volume knob, it should start blinking, then pair it as headphones. I use this in my rv project for my computer and some bookshelf speakers, works amazing. I also use it if someone wants to test some speakers before i sell them. Using an old 19v ryobi power supply (charger free with battery, got like 10 of them) to power it, works great. Works fine at 12v, blew some 10w speakers when i powered it with 24v... For the money, it delivers better than most.

Surprisingly good sound quality with Bluetooth! Just make sure to use a 24-volt adapter that can handle at least 4 amps to get the most out of it. But it’s okay to use any adapter since the amp automatically adjusts to what effect the adapter can provide. Overall, really impressed!
