My current setup is 1080i SDI inputs and I use input 1 of the analog XLR inputs on my 4800. I currently Split Play by play and NAT sounds between the Left and Right Channels.

Ideally if possible I would like to record play-by-play on Left and Right (Audio 1,2) Then on Audio 3, 4 I would like to record NAT sounds and In-House PA. Is this something that is possible?
