Class-d for a 1kw PA amp

[MikeHunt79]

41hz AMP8 and SMPS?

Just a quick question, anyone using the AMP8 with an SMPS?

How well does it work? What power rating is the SMPS? Would an 800W SMPS be enough to drive speakers at 600W rms?

I think 800w smps is enough for 600w amp.

I've been looking into some sort of class-d amp for PA use. Something that will do around 500W into 4 ohms per channel and 2 channels. Basically something like a QSC RMX but doesn't weigh 20kg. 🙂

So far I've looked into building the 41Hz AMP8 kit with a 800W SMPS which gives +-60v. It wasn't until I came on here I realised that there are other things around.... Hypex, Coldamp, etc.

Is there a site which has a list of all the higher power class-d amps? I've seen a few more class-d amps from lesser known people (class-d.net for example), and I was wondering if these are also worth considering?

In practice, with full-range music signals, a SMPS capable of 800W continuous with current limiting and enough storage capacitance, you could power four or more 500W channels. Class D is efficient, speakers are reactive and music uses little power.
