microphone power amplifier?

Postby smh69 » Sun Aug 13, 2017 3:01 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 https://www.icrfq.com/products/ more suitable device?

It would help if your question was clearer. What is the input to the mixer from the microphone? Is the mixer input specified to suit the microphone levels or from an amplified signal?

An amplifier will not cause distortion due to excess heat. The excess heat may cause some components to malfunction and these may introduce distortion.
