At the moment I'm a student on a highschool in Belgium, I'm studying electronics, and I would like to build a "strong" amplifier for use in a discobar (our hobby).
Do you have a schematic of an amplifier which can drive two speakers of 350 Watt RMS (99dB/W/m) without any problem? The problem with our current amplifiers is, that we can't play loud enough without clipping of the amplifier or the mixer (what isn't very healthy for the tweeters).

I thank you for reading this message.

Best regards,
HugoBross

As a general guide:

The new amp should be at least 6dB(4x) and prefferably 10db(10x) more powerfull than yhe one you use today.
Otherwise, the incremental gain in volume will be too small to be worth the change.

Hugo,

Check out the N-channel power amplifier at 'http://www.ausiamplifiers.com'. I've never heard the amplifier, but I've heard good things about it. There is a schematic, PC board, and a construction manual for this. I don't think there's a full kit (components included) available.

If more power is needed, he also has a 1KW amp, but you'll need to get the details on this from Tony. There are lots of pictures, but no schematic.

thanks, but actually I prefer transistors above mosfets. They're cheaper and they sound often better than opamps. So, I'm looking for a schematic with transistors.

Hugobross.

Hi Hugobross

I think the trick here is to use a active crossover and two poweramplifiers. One for your lowfrequens speaker and another for the rest of the drivers. If your lowfrequens amplifier clips it does not affect the rest of the drivers. so instead of getting bigger amplifiers get more amplifiers.
