DollaTek Audio Amplifier Board, PAM8406 Digital Power Amplifier Board 5W+5W Immersion Gold Stereo Amp 2.0 Dual Channel Mini Class D DC5V Amplify DIY Circuit Module

Brilliant little device and produces good load sound

It does all it needs to do but I have lots of interference and unwanted noise when it's plugged into the same power supply as my Bluetooth board although I don't think that it's the amplifiers fault

I bought this to install in an arcade cabinet I was building so I could control the volume with a physical dial rather than through the front end software. Simple to install and does the job perfectly.

The blindingly bright power LED was fixed with a couple of dabs of marker pen. The big reservoir capacitors are wired after the power switch so expect brownouts on your 5V psu rail if you accidentally turn the amp off and on with the volume control. The class D mode works well and there are RF filters on the output. There's a tiny zero-ohm link soldered on the board that you can move to make it class AB but it's hard to get to with an iron and it was sounding great anyway so I didn't try.

Using this in a miniature home made pinball machine, it really does the trick. Completely lacks bass, but I don't need that for the tiny machine I'm building.

Amplifier productes a nice clean sound. Worked straight away. However the bass is severly lacking. I thought AC/DC was missing their bass guitarist, (which is not good). No tone controls on the amp. So its still the car stereo for AC/DC .

Some reviews of similar boards mention problems with the terminal screws, on mine they are tight, and I would recommend unscrewing them before you start mounting it inside something. I wanted to use RCA sockets, so I soldered some wires to the connections on the volume pot, this seems to work well. There only seems to be film caps in the signal path, rather than SMD things. It seems a well made board and driving some two way speakers (apparently it would be better with a full range ) it fills the room with sound, I have pushed it to far, and the distortion was bad, but at normal (for me) listening levels they sound sublime. HIGHLY recommended (especially if you listen at low-ish levels.

Very good product. Well built and easy to use.

Funciona bien pero tiene poca potencia

Ottimo prodotto ! Ottima qualità dei materiali. Usato per un Bartop/Arcade con casse 5w+ 5w Benissimo!

Konnte es fast nicht glauben, aber was dieser kleine Verstärker Baustein Liefert ist ein kleines Wunder. Habe den Verstärker mit der 3,5mm Klinke über mein Handy verbunden sowie ein USB-Netzteil und kleine Grundig Boxen. Bei Zimmerlautstärke eine sehr geringe Stromaufnahme von 100mA und ein sehr guter Klang. Auch bei längerer Nutzung mit nahezu maximal Leistung, praktisch keine wärme Entwicklung. Sehr Empfehlenswert !

tout correspond à l'annonce. le produit est de bonne qualité je recommande pour des petits projets son.

Parfait petit ce ampli pour tester le son de petits haut-parleurs avant de les installer. Maintenant je vais l'essayer sur du plus gros, genre satellite, et entendre ce que ça donne ? D'abord je le mets en boite proprement il en vaut la peine. Encore une réalisation de maison DollaTek que l'on trouve sous différentes signature. Merci à ce fabricant.
