PowerAmp

jps000jps · 14th January 2010, 10:47 PM

I just decided I am going to put my ADC 303AX loudspeakers to use. I want to make some kind of power amp with a 1/4" input cable, and I want it to be stereo. This way I can play music off my iPod (I have an adapter) or plug my guitar amplifier into it. I have no Idea how many watts I need to use or how to make it. If anyone can supply me a little schematic, shoot me some info/ideas etc. I'd greatly appreciate it. Thank You!

To keep it simple I would just make some sort of chip amp. The LM3886 is a popular choice. Here is the DIY thread talking about it.

That could be easily done in stereo, and should have enough power to run the ADC 303AX loudspeakers fairly well. Your ipod would connect straight into the amp, no need for any pre-amps.

Thanks. I was thinking a chip amp would be the way to go. I was not going to make a pre-amp anyway ha ha.. Ill look in that thread to see what i can find.
