I just got a complete system arc ultra sub 4 and era 300.  Was playing around with it and I got the same sound from my sound bar   As my rear era 300. And it sounded fantastic  then I must of hit a wrong button in the app and everything went dead no sound.  Got it back working but on my era 300 alls I get is the surround sound now question is how do I get back the same sound out of my arc ultra as my era 300s at the same time
