Separate Gain Structure for FOH and broadcast

New

Hello,


We are currently dealing with an issue of sharing the same gain structure for our FOH/monitor and online broadcast mix. We are using a Midas Pro2, DL251, and DL155. We are also mixing "in the box" for online broadcast in a studio not close to the location of the stageboxes. 


What recommendations would you give for separating the gains for each mix. I recently saw we could use a DL451 splitter and feel this may work. Is there any other AES50 device, besides a mixer, that can remotely control the DL451's separate preamps (a computer or software)? This would be useful to be able to control the gains, independently of the FOH gains, for the online broadcast mix from the studio instead of locally at the DL451.


Any help and insight would be much appreciated.
