LM3886 PA/Live Sound designs?

takodabut · 20th December 2006, 05:49 PM

Does anyone have a design for PA amplification using LM3886?
I'm thinking small venues, 100-300 watts.

Do you want it just for the Amplification or do you want it also to have the Mic preamps in it and Line inputs and Mixer capibilities and EQ ect??

If you do need all of these features I think it would be a Very difficult to build and be very costly, It would be easier to just run a Mixer into a Stereo Chip amp out to PA speakers....

If you allready have a Mixer and just need it for amplification then I"m sure any of the Bridged/Paralell Stereo/Dual Mono configurations from the LM3886 Datasheet would work to power speakers for small to mid sized venues......

Good luck

I'm looking for power amp only, to be fed by a mixer.
Thanks. I'll investigate the data sheet.
