We're hired for a tv production, where we do 1 out of 6 rooms and have to do the mixing.

The producer asked us if we could send out a program mix over sdi, and another aux mix over sdi simultaniously. Also a question was if we can deliver the audio over multiple sdi channels.

We have HD licenses now, but would upgrade one if this is possible with the 4K version.

So can the 4 K version do a seperate mix on the 2 external outputs? And how would this work? The aux mix doesn't need to be changed that often, it's mostly a backup in case our program mix is not what they need.

For audio: is it possible to send out audio over multiple sdi channels, and how would this be done?
