2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board
2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board is rated 4.8571 out of 5 by 14.
Rated 5 out of 5 by from Superb Tripath SoundJust hooked this up to my home stereo. I have a number of Tripath based amps that use the TA2020, TA2021 and TA2024 chips. I've also got an amp that uses the newer TPA3116. To my ear this sounds as good as any of them. Since it (obviously) lacks a volume control, I hooked it up to an Bravo Audio Ocean Preamp and it is a match nearly made in heaven. Even though this is only an 8 watt amp, the Bravo Audio Ocean has so much gain that you'll be shocked how loud you can drive your speakers. My only complaint is that I can only use about the first 1/10th of the travel in the Bravo's volume knob before it gets too loud with my 92db Axiom M3 speakers.

Rated 5 out of 5 by from Wonderful little thingBought this little guy, because I wanted a TPA3116 but didnt want to wait for an order from China. And Im glad I did. I love this Amp. I currently have it installed with a rat shack pot in an old wooden .22lr ammo box. Using a pair of Boston HD5s, the sound is stellar.

Rated 5 out of 5 by from Very clean amplifierI bought this amplifier for a portable bluetooth music player. I bridged the amplifier to run 16 watts mono. I am powering a Tang Band W3-881SJF 3" Full Range Speaker and the outcome sounds fantastic. The battery life is also very impressive due to the efficiency of this amplifier.

Rated 4 out of 5 by from Nice Sound, Good PriceI bought this to give me a speaker output for my digital recorder that I use for music practice. It works just fine and has a clean sound through small bookshelf speakers. My only complaint is that it could have used two more screw terminals for the input connections.

Rated 4 out of 5 by from Pretty decent ampI've built a few versions of this, but I've managed to keep this one. It has Elna Silmic II caps, and an Alps blue velvet. I can't get enough of the smaller power chip amps. There a lot of fun.

Rated 5 out of 5 by from Great Amp!Audiophile quality sound for cheap. With a few mods this little amp is amazing! Don't let the low power fool you. It will drive fairly efficient speakers easily. Especially good for computer sound systems.

2x8W at 4 Ohm TPA3110 Class-D Audio Amplifier Board

I soldered my board up yesterday. Unfortunately, when I hooked it up to my Acoustat preamp and Tekton OB4.5 speakers, I get a constant "thump" from the speakers and the music that's there is very, very low. Any thoughts?

I'm confused by "board only" in the description. Is it just the circuit board and I have to purchase all the little bits that it shows in the picture separately or is it all there and working, I just need to add an on/off, power and volume?

Asked by: tlb18
"Board only" simply means this is not installed in a casing. You will receive what is pictured, which is a fully functional amplifier board, completely assembled with all required parts, just not in an aesthetic case.

Popping sound when powered on?

I built a little power amp with this board. I turn it on by plugging in the power supply (poor man's on/off switch). When it powers on, a "pop" comes out of the speakers. Does anyone experience this, and if so, what's the best way to remedy it?
Asked by: MattG
that "pop" sound is simply the caps filling up with power, no need to worry
