Default Suggest a DIY PA amplifier project

Please suggest a DIY PA amplifier project (around 50W) with built in mic amp?

If a PCB layout is available that would be very helpful.
regards

Well I don"t have any Specific schematics or PCB"s in Mind But I could tell you that probably the easiest way would probably be to make a Stereo Chipamp (LM3886??) and just put a couple mic Preamp channels at the input with a Pan Pot so you can adjust the Panning......

There are several Places that sell Chipamp PCB"s and there are alo several Good Mic preamp designs on the net of which most would be suitable ,You can even put a small Mixer curcuit between the Mic preamps and the Power amp stage which would take care of the Panning and summing of channels.....

I am thinking of doing a simular Project but I haven"t had the Time or the Real Need at this time to start designing and building it yet.....To many projects on the go right now.....

Good luck
