Nice little amp

Bought this for my gp star proton pack project It has good sound and a nice compact shape which is nice to be able to squeeze in Overall no complaints Many people who were using this for the same project had a issue with noise Putting a diode in series with the negative or ground connection for this unit will eliminate that humming or noise if you are powering your sound supplying device from the same power source

Horrible junk

I bought a 2 pack of these and neither one produces any good sound. Both of them are very hard to get RCA into. Plastic isnt molded correct and have to push very hard to get them in. Soon as power is on they produce popping and whining noises that are very annoying. But no sound comes out from the input

Good but not perfect.

So I am basically using the 3.5mm audio jack for input but I wired directly to a PCM5102 also purchased from here. https://amzn.to/49uvKUO Now, I have to say it is working great as long as I do not touch the volume control. It is not totally bad but you can get quite a bit of hum at high volume by just touching the volume. It may get better once I put in a case it is open air right now so the 60 Hz is easy to pickup on low side audio. However, there is a thing that makes this worse. The RCA jacks, they appear to be wired backward. That is the gold outside part of the jack is actually connected to the Left and Right + inputs! OOPS, that is not good that is supposed to be the grounded part of the RCA with the tab on the inside of the hole the Pos Line in so this makes it like an antenna for 60 Hz and if I touch the RCA gold outside surface the 60 Hz is terrible! So, I am going to remove them from my board to help raise the noise resistance. I will not be using them anyway. They did something strange with the diff input on these RCA jacks. It probably works but with the outside flipped like it is I would not use the RCA use an adapter and use the 3.5mm jack. I have not found a schematic to prove this case however my multi-meter tells me the Left Positive Line on the 3.5 jack is connected to the Outside of the Left RCA plug and the same holds true on the Right side. Again, I am removing them so it is not a big deal to me. Just FYI in your use of this amplifier. Double check the RCA jacks before using them!!!

This thing works well

Nice Amp, Nice Upgrades!

I've been ordering these amps for years - have used them in a variety of DIY projects and commissions. What i LOVE about the most recent version (v5) versus the earlier version I was using, is the addition of solder pads for power input, speaker outputs, and audio inputs! Sometimes when I'm building a project for installation, I want to know that the wires will not wiggle loose, or perhaps I'm using wires thinner than ideal for the screw terminals. These solder pads are super handy! I would love if V6 made them through-hole instead of merely surface mount, but I won't complain. Love these little amps. The sound is the best I've heard from a small, low-cost amplifier module.
