What happens if you have 3 optical inputs all connected?

[Jamington2004]

I can't test that I have 4 sources into an optical switch into the dialogue - so only one will ever be sent depending on the source I select on the switch

But yes if you had dialogue, and both phantoms set to optical with autoswitch it would be an interesting experiment to see what happened!!

Maybe a new way of Djing / mixing songs together without a mixer
