Reactor600 + Phantom Golds

[eniriop]

I have a couple Phantom Golds and I'm looking to get a Reactor 600, more so to use it as a portable set-up but I'd also use it paired with the Golds. 
My question is: if I plug an optical cable from my TV to my Reactor will it feed the signal to the Golds as well? The 3 speakers would basically be in a multi-room setup and I haven't seen this use-case discussed before. 
Thanks!

I have an optical cable from my TV to one of my 2 Gold and I have a pair of reactor in another room. With airplay 2 you can have the sound of the TV in both rooms, if you want to, or just in one room if you choose that. It helps if you have a good wifi network such as a netgear orbi with 2 satellites.
