More than 1Kw...
 
Have you a scheme of a amplifiers (better if in class d) of about 1 1,5kW rms?

I must make of the amplifiers for small concerts...

1 KW Class D
 
The ICE Power 1000ASP amplifier from B&O is a complete power amp with a power supply. Works great. Sounds Great. Have a look at their home page. I'm not sure where you'd buy it but I tested one last week and was quite impressed.

ICE Power amplifiers
 
For those of you unable to do a search at google, here is the URL

http://www.powerhouse.bang-olufsen.com/sw1022.asp

I must admit I have an advantage. I had dinner with the chief designer at the Audio Engineering Society convention last fall in New York City and he paid. Actually, I have been getting sampled on all their new products for some time and have been dealing with the whole ICE Power group for several years.

See my products using their products at www.rh.com. The PM series amplifiers in our ST series speakers are 100% class-d amplification using these modules.

I just tested the 1000ASP last week. Its bloody awesome. Burst power to 1244W RMS with no additional heatsinking needed. It can pump out 1 solid 1020W of music all day long. THD+N in the .02% region. The S/N was -95db unweighted to 30KHz and when I turned on the A weighting filter like I should have, the noise level was unreadable. And my APb can read to better than -140db.

The only thing I can't do is tell you where to buy them. That you'll have to find yourself.

With a toroidal trasformer of about 1,5kva (1 for channel) the version with 20 mos can draw 1,5kw rms?
