## Customer Reviews

### ⭐⭐⭐⭐⭐ Great sound quality
*by D***3 on December 31, 2024*

I ordered 2 of these, 1 spare, to replace 2 Class-D digital amplifiers. The Class-D amps had very poor bass response and and sounded too bright on the mids and highs. It also required a 24 volt supply, which meat a separate 12V regulator for the VU meter circuit. This item took their places with no changes to the preamp at all (the preamp was tested separately for frequency response after I noticed the lack of bass). The change in the sound was night and day, with the full spectrum being reproduced. This is on good quality KLH speakers and connected to the line out on my computer. The bass is deep and tight. the bass drums have punch, yet the foot pedal notes from an organ are there also.I highly recommend this amp!

### ⭐⭐⭐⭐ Good Quality, TDA7850 chip, Exaggerated Specs
*by J***T on July 14, 2024*

Interesting little board for the DIY / hobbyist crowd. It uses a ST TDA7850 chip intended for 4 channel automotive applications. The subwoofer implementation is pretty straightforward, although it should be noted that the subwoofer uses only one of the chip's amplifier sections, it's not 2 sections bridged as you might assume from the advertised specs. Look up the ST TDA7850 datasheet for more realistic specs.Despite the specsmanship, I found this to be a nice alternative to all the Class-D boards out there. I measured about 60W into 4ohms at clip with a 15V supply, impressive for the price. Sound quality is about what you would expect. It's obviously not going in any audiophile systems but would be right at home in desktop A/V applications.

### ⭐⭐⭐⭐⭐ Amazing sound quality, and build quality. Highly recommended
*by R***R on July 23, 2022*

This is a really nice amplifier board, and I've tried a few. This review specifically pertains to the model being listed here, "Class AB Amplifier, DROK 2.1 Channel 80W+80W Stereo and120W Pure Bass 9-18V 4Ω Audio Amplifier Board". Some of the older reviews appear to be talking about a totally different product. This one does not have bluetooth.Honestly the sound quality from this thing is outstanding, it's clean and loud and music sounds fantastic. K have it hooked up to an ATX power supply that I use for my car audio equipment at home, pushing 12v through a fused distribution block. The input is a 3.5mm aux connection to my Galaxy S22 USB-C out, converted through an in-line DAC.Upon initial turn-on, a nice green LED lit up,and there is no noise whatsoever coming out of my 6.5 inch coax speakers. No buzz,no fuzz, no hiss, and no piss. A beautiful thing go experience if you've been let down by some of these mini amplifier boards previously like i have.I also hooked up the subwoofer output to my 10 inch sealed Infinity REF sub at 2 ohms. The balance is unbelievable! There's only one volume control know, so there is no way to modulate the sub or speakers independently, they're just mixed on the board, but the mix is super nice and balanced.Overall I'm super happy with this amp. It aounds better than other amps that cost multiples of what this one cost me ($23). I recommend it without reservation, just make sure you know what you're doing and have the 12v equipment needed for running this in your setup.Kinda wish it had bluetooth but I knew it wouldn't going into it so that's not an actual knock on the product. Just a wish.Good luck and enjoy. This thing puts out loud clean clear audio signals for your speakers!!
