Power Amplifier

Postby smonirh1 » Mon Aug 14, 2017 1:21 pm

would like to feed a non powered microphone (like pc headset type) into a mixer over a cd playing.

do i need a pre amp and low power amplifier?

I have built a pre amp and a TDA amplifier but the heatsink i put on the amplifier gets so hot and after a while distorts because its too hot.

Anyone see on a cheap build website like this a more suitable device?
