Anyone can help me to convert mono audio out to stereo audio out?

Question

if any one know ples tel me how to do it, with circuit digrams

Answer 1

Once the audio has been combined into mono there's no practical way to convert it back into stereo.  It's kind of like trying to unmix two paint colors after stiring them together.  You can provide the mono feed to both sides of a stereo amp so you get sound out of both speakers, but it's still mono audio.

Answer 2

use a mono to stereo cable.look around and see which one fits your needs ,theres different types.
