I have an audio source input, that I am putting through the circuit below to create a balanced audio signal.
There will be one of these for each channel, left and right.
I have been asked to provide a "balanced or unbalanced switch", so that a user can flip the switch and have either balanced or unbalanced audio out.
But, as far as I can tell, if you want unbalanced audio from this set up, you would just take the audio from pins 1 and 2, and dont connect pin 3. This gives you an unbalanced audio output.
If I added an extra stage to combine the balanced audio to unbalanced, then I would just be converting back to the original input signal.
Or am I missing something here?
Is there some way to add an "balanced or unbalanced switch"?
