Pairing,, that is what you did to the 300s. As they are now Paired they are not available to be added to the ARC Ultra Room.

If you want to do that unPair them and then you can add them as the Arc's surrounds.

I cannot get the studio pair of era 300’s to work in conjunction of the existing theater system

You are not able to add a stereo pair as surrounds. You must separate the pairing first:

The 300s will show up as separate room initially, but when they join the Arc Ultra, they will become a single room.

Can the studio pair work in conjunction at all with the existing arc ultra??

Yes... but.

You can Group the two Rooms and stream music perfectly.

If you Group the two Rooms and play a TV source there will be an echo/delay of 75 ms on the 300s.
