I implemented the following audio mixer circuit with just 2 input audio sources:
Both sounds got mixed properly.
Then, at the end of that audio mixer I connected an audio splitter like the one below:
which provides me two female connectors.
- on one female I connected an amplifier with a speaker
- on the other female I connected a headphones (without microphone)
(for more details, please, check the image below)
My problem is: If I speak through the earphones of the headphones, then I can hear that on the speaker and I don't want that to happens. I just want to listen what's comes up from the mixer but nothing else.
Any idea on how to avoid this to happen? (which is actually weird, I could not expect that to happen).
Thanks in advance!
