microphone power amplifier?

[smh69]

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?

any help

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.

cheap build website may not high quality.

if you want to build, you can go to [url]elcircuit.com[/url] his website almost about power amplifier.

I was under the assumption that electret microphone capsules do not require any phantom power an can be connected in the same way dynamic microphone capsules can be, due to the fact that they contain a small permanent static charge built in. I am trying to build a really simple mic to hook up to my computer via the 3.5mm mic jack, and after wiring everything up, it doesn't seem to be working. Is this because there is in fact supposed to be some sort of phantom power circuit, or should I just double and triple check my wiring again?
