Rated 2 out of 5 by from HissNot the best product -- creates a hissing sound that can be heard especially when sound is quiest.

Rated 5 out of 5 by from Nice little amp!I picked this up last week and it's impressive. I didn't expect it to be so tiny but it has a nice big sound. I tried it on several sets of speakers and it didn't blink - lots of volume and no heat. I'll be picking up a few more for some of my projects.

Rated 5 out of 5 by from Can't beat it for the price.Let's get one thing straight, this is not an expensive, hifi, amp module. It's a small, cheap, project board. And it works. Yes, it can be noisy, but there are a few work arounds. If you turn the source up and the amp down, it is totally negligible. Also read the sheet about noise reduction caps, that has worked for folks and is cheap.The only real noise issue I had with it was when I had it sitting about 1/8" behind two large speaker magnets - duh.I was tempted to rate it at 4 stars, but then I started thinking - taking into account that it has a TINY footprint, is true stereo, and a very solid 10 watts, I had to give it 5 stars.

Rated 4 out of 5 by from Such a tiny powerhouse!originally was going to power a couple 8 ohm bass shakers in a car seatworks great in house (9v switching) and when the cars not runningHowever quite a bit of noise and only with the car runningI came up with it needs a input or Ground Loop Isolatoralso 99% sure it is within the amp itself and not an external ground loopJust dont know right now how much more I will try with this project in this direction (have a real car amp I dont want to mess up)but I have other projects I can use this amp on!I did look at other cheaper versions of this same amp and noticed PE seems to have a thicker board +I had some 8X8 heatsinks and put one on it.I dont think it ever has even got really warm but it looks good.Anyways such a neat little amp with good sound and power .maybe should have bought two!

Rated 3 out of 5 by from Noise issue when powered with a switching supplyThe amplifier is small and very good when it works. We had an issue though in which the amplifier transmitted a hum into one of our speakers in our application.I looked at the amplifier and noticed that it was using the PAM8610 amplifier chip. I looked at the specification sheet for that device and found that it requires a couple of capacitors on the input power pins for this device; one for low frequency noise and one for high frequency noise.This device has the capacitor for the low frequency noises you might find in some low performance power switching type supplies. Ours was a higher performance power supply with ran at a higher frequency. This noise caused the circuit to oscillate a tone onto the connected speaker.To get rid of this issue, I connected a 1uf (50v) ceramic capacitor across the negative and positive leads of the power input connector. This fixed the issue. This capacitor is also discussed in the PAM8610 datasheet.

Rated 1 out of 5 by from Save your money.I knew this was a cheap little amp module, but decided to take a chance on it for a small powered speaker project, based on the other reviews here. I guess I got what I paid for, because this cheap little unit was full of problems from the minute I tried to use it, and in the end, it just didn't work for me at all. First off, the 1/8" input jack was loose, causing intermittent audio. I soldered on a more reliable jack, and solved that problem. Then, one of the leads of the on-board volume pot broke. It's leads are really thin and flimsy, and were just ready to fail. So I soldered on a new pot. Then, after hooking it all up, turns out that this unit can't even handle mildly hot inputs. The audio goes out (I'm assuming due to clipping or overloading of the chip) when input volume exceed a certain threshold. I'd be okay with this if that threshold were reasonable (e.g., a bit above line level), but, and here's the thing, the threshold is low enough that I can cross it with the signal from a Hi-Z mic. If I keep the input volume low enough to not cut out, then I get barely any volume at all. So, what's the point? Save your money and buy a better amp unit.

PAM8610 2x10W Class-D Audio Amplifier Board

Can a 9v battery power this? Or will the amp cut out at high volume?

Asked by: Amp Question
A 9v battery will run this amp, but it will have very limited battery life.

How much current does the 2x10 watt amp draw?

Asked by: Timrsimpson
We recommend a 2A power supply for this amplifier.

I don't see a link to a posted datasheet, so I'll just pose the question here: Anyone know what the input impedance is for the unit? Thanks.

Suppose I wanted to connect four PAM8610 amplifier boards to the same source unit, how would I do that? Would it require a preamp? Also, are the two channels bridgeable to a 20 watt mono? Thanks in advance

WHERE is the power supply [tip] polarity specified?

Asked by: LaraCroft111
It's not, but the center tip is positive on this amplifier.

Speaker connectors? What to use? Where to get?

Asked by: LaraCroft
The amplifier comes with two small wire leads with plugs for the amplifier. These are to be spliced into for longer cable lengths.
