Power supply and sound

So the amplifier board needs a powerful power supply. At the moment I have a 24v 90w 5 amp power supply and it does the job perfectly! The sound quality is partly excellent. Don't expect too much for €20.

Pros
  • GOLS certified
Cons
  • Will be added later

Impressive surprise

This little thing is cool. I never expected to hear what the result was at such a high price. I have some crappy Samsung surround speakers and they sound amazing. I can only imagine how it would sound if I had better speakers.

Pros
  • Good thing
Cons
  • Vulgarity

Little beast with good sound.

I actually bought this to use as a demo for an audio repair and design tutorial and all I can say is wow. For the price and size, the sound quality is excellent and the build quality is very good too. .I will buy more. We'll probably modify it to death, but I see so many uses for it in our projects.

Pros
  • Nice to use
Cons
  • Not bad

Far From Perfect - Home Audio

This is a decent amp. Pretty loud, but I have 3 questions.1. The crossover frequency of the low pass is too high. The subchannel can even be full scale. I plan to add a crossover. 2. Loud. Hums/hums when master volume is set too high. It needs some adjustments to get it right. 3. No power switch. As far as I can tell it only turns off when unplugged.

Pros
  • Best in Niche
Cons
  • No

great amp but poor durability

I ran it with a 12V 3A power supply, the amp had a thud when plugged into the Mi Box S when it was off and the bass channel suddenly stopped working. There is no cutoff frequency setting, but the power rating (in combination with the correct power supply) is as advertised. I would recommend using it with a passive crossover and matching the switch to the power supply.

Pros
  • regular price
Cons
  • factor set

Just what I needed for home audio

This little amp performs well. I only needed it to drive the subwoofer hard enough. Well, for an experiment for the grandson of elementary school grades. It worked very well, withstood the bad relationships between the little guy and his father, and moved on. The hollow power connector is the same size as the 120w power adapter I already had for my old laptop, so it worked great for my purposes. For what it's worth, my output scope showed a nice clean sine wave across the range, but I've never…

Pros
  • Good workmanship
Cons
  • Functionality
