Sorry for my english i'm a young french.
I want to design an audio transmitter to connect my pc to my Hi-Fi without Jack cables.
For now i just want to send a mono signal because sending a stereo seems to be too complicated and i don't need it.
The problem is that my PC's output is a stereo jack. So is it correct to merge the two signals in once, using an operational amplifier in buffer or summing ? Will the sound be ok, just suming two signals ?
