Walfront DC 1.8-12V TDA2822M 2 Channel Stereo 3.5mm AUX Audio Amp Board Module

Great little amp. Works well on a 5 volt USB supply. Probably about 750 mW across an 8 ohm speaker.

Brilliant little amp for the price, however the left and right channels are the wrong way round on the jack which can be very detrimental in some cases such as using it for video games with directional sound, but easily fixed by swapping speakers around or by soldering on a new aux connector the correct way round

It's hissy and that's quite annoying, but it does work.

The sound quality is good. I used it amplify a radio circuit I constructed with very good stereo results.

is this a preamp? i got no sound at all tried 2 volts 5volts 12 volts nothing

I wouldn't use it as a main audio amp for serious listening, but it makes a great little amp for projects, mine's inside my homebuilt arcade machine and it sounds good!

Works really well. I used this to re-purpose some old internal laptop speakers for use on my desktop and it works fine running off USB power.

Used this inside an arcade cabinet. It provides decent sound but I find it doesn't do a great job of keeping signal noise to a minimum. As a result I hear a fair amount of humming and buzzing when no sound is being output.

Ich benutze das „Verstärkerchen“ als Audio-Booster in einer Photobox. Funktioniert perfekt und macht auch an 12V gut Lärm. Leider ist es sehr empfindlich für Störungen auf der Versorgung so dass man unbedingt einen 2200 Mikrofarad Elko einlöten sollte. Rauschen oder Verzerrungen auch bei maximaler Lautstärke konnte ich keine feststellen. Klare Kaufempfehlung!

Eenvoudig ontwerp. Ruim ingangsspanningsbereik. Goede klank. Makkelijk met schroefklemmen en mini input jack. Past in klein doosje .

ras tout parfait

Buona amplificazione

Este es el segundo que pido, es tal y como se describe. El otro esta funcionando perfectamente, necesitaba un segundo mini amplificador y no dude en comprar otro de nuevo. Muy contento con su rendimiento. Gracias
