Phantom's Toslink is not ready for live musical instruments

[ogs]

Delayed fingers... that's a thought!
Considering the fact that Devialet has a rather long list of unfixed issues related to both Phantom and Expert I doubt your idea of a "direct in" would have a chance. The only way to find out is to ask them directly...

EDIT sorry, I see from your first post you have already contacted Devialet about this..

Yes, a mind twisting thought indeed 

I've contacted Devialet support again with a feature request for a software-side "direct in" switch (pointing to this thread). She said she'd forward the feedback to the engineers in charge of development.

There seems to be a development here. Devialet may have given in to pressure and made  a 'amplitude only' firmware for Phantoms. Look in this thread: http://devialetchat.com/showthread.php?tid=3388
