DROK 15W+15W Audio Amplifier Board

The input source has to be plugged in otherwise it is very difficult to attach it. For instance, I needed to connect an alarm speaker, which came with bare wires to an amplifier and there was no practical way of connecting this. On the other hand, if you need to connect something with 3.5mm jack it is perfect as in the video. Very good quality and does not need a heat sink because it does not get hot. Good sound quality for its size.

I purchased the 15+15W amp for my bartop arcade and it has been perfect. I also got the Pyle PL42BL 4-Inch 180-Watt Two-Way Speakers (Pair) here on Amazon for $13. Nice sound and great price for the setup. I am running a 12v 2a power supply to power the amp and it seem to be providing enough power. Been using it for a few weeks now and not one single issue. Super easy to install.

For the price, it’s pretty good. However, I found the RCA inputs to be noisy. That being said, it makes a great small amp for projects.

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

Works for my arcade 1 up mod

I gotta say im impressed with the visual quality of this and the audio quality. I used it to replace bad audio on an arcade and it it works and sounds great. But visually what a nice looking board. I wish i didnt have to cover it up. Gold trim everything.

I had the DROK 5W + 5W Mini Amplifier in the past, it works great, but I wanted to have a 12 VDC. This is the complete opposite, The Volume adjustment is scratchy with no ON/OFF function, the audio is terrible on the higher settings, I tried two different styles of speaker with the same results. Also any impedance change shuts the audio off, and you must cycle power to get the audio back.

Nicely built. Sound is very good running at about 7 watts of power, unable to push it harder than that with what I have on-hand. This is a good value for the money if you are looking for a small, easy to use audio amplifier.

Excellent tiny amp for my arcade projects. Love the design and size. Works really well. Will certainly be buying more for future projects.

This thing is a gem. Perfect for built-in sound needs in any project. Sounds great using 8ohm desktop/bookshelf speakers.

So far I've just been throwing salvaged laptop, TV, and all in one PC speakers at it. The amp drives clean and the RCA/3.5mm option is great. Only gripe is I cannot solve a noise issue. They blare some sort of hum when a device isn't playing music and then stops when the device plays. Very annoying. If I can solve that I'll use this board for a lot of builds, likely. I'm hoping it's my fault and not a fault of the amp. 4 stars until I solve it. Will change to 5 if I do.

We used this for a Li-Fi project. Works great. Pleased and the price was good.

The sound is very tinnie. Don’t like it.
