I have brought my Sonos system into a new home already fitted with a Legrand OnQ Cat5 LyriQ whole house sounds system. I have four areas served by this system including an outdoor, covered deck - the system seems to use a line in signal which is amplified at each location through an amp built into the wall control. Getting support from Legrand on this system has been an exercise in futility. What I'm wondering is if I need a Connect or a Connect:Amp for this system to stream music to these non-Sonos areas? My instinct tells me its a Connect only, but I'm wondering if anyone has had experience with a similar system - past whole house systems I had needed to be amplified at the source which was then connected to the whole house speaker selector, not this one.
