Can a generic Class D power amp works?

[richfirstbass]

OTOH, I have used home audio units that required adapters but sounded great! Especially the second one. They weighed quite a bit more than a Class D amp module, though.

Wow, that Macintosh 2300 power amp brings back memories. I wanted one when I was in my 20's and a touring musician. But the price, but more specifically, the weight of 128 lbs. changed my mind. I don't think my girlfriend (now my wife) would have helped me carry that around. Couldn't argue with the quality of that build.

In Canada, you need either CSA, cUL, or other NRTL approval to cUL 62368 safety standards. This is overseen by each provence’s hydro department. The product also requires compliance to FCC part 15B standards (Canada and the US are aligned on this) This is also a legal requirement. If you choose to ignore this, it’s on you.


A pro audio PA amp is designed and built many times more reliably, for example you won’t find a single pro audio power amp powered by a wall watt.

absolutely, listen to this man!

It’s not legal for sale, but clearly it is being sold. Whats the potential outcome of that illegality? Home insurance is void, federal crime with jail time…?

The home insurance aspect, if things actually go awry, is extremely serious if you are out hundreds of thousands or a million or more. But yea, I think those are the main points.

My girlfriend, now my wife, never carried anything, but my gear has almost always weighed more than her!

The 2300 isn't mine. I've also lusted after one since my teens, but they are so freaking heavy. I can't even lift my MC2255 which is 40 lbs less. I have no idea what I'm going to do when it finally needs servicing.

Apart from the external power supply (as I already known), from your comments here's the differences:
- cooling
- physical connectors
- reliability (possible)
- filtering (possible)
- missing electrical certifications
- peak advertised wattage instead of RMS
- coming from unknown source in China

Thanks all of you for your comments.

. . . . power amp with a WALL WART . . . .

Never said I would buy it, I just wanted to know what are the differences between this class D power amp and the class D power section in a bass head.

Well, let us know how it turns out if you decide to get it.

Not to get overly technical, but from what I’ve read, the class D power section is merely only a PART of these modern bass amps. Yes, obvious issues like input level and physical connectors and power supplies come to mind, but there’s actually some very complex filtering going on as well. The way class D works Introduces all sorts of noise that you wouldn’t have gotten when you tried a generic standard type of power amp for a PA in the past. The bass amps use filtering to remove that sound from the class D. It’s required and different based on the use. Perhaps someone that knows more about this can shed some more light? Hope this helps.

The low pass reconstruction filter on a class D amp’s output is integral to the design, and it’s required for proper operation.

Fosi V3 Mono Block
370w @ 2ohms 1% THD for $125



The power supply is bigger than the amp itself.

This first run will sell out quick, but Fosi is good about scheduling batches.

So I bought a 100w class D power amp on Amazon (Moukey I think?) with the idea that I would use it as a practice/home amp that I could connect my pedal board and small cabinet I have to.
Found out that was a major pain in the butt that I never could be motivated to do and wound up buying a Rumble 25 off of FB Marketplace for $40. I can still plug my pedal board into it if I want to. I never do. The Moukey just sits there, not sure what practical purpose I can use it for.
