Hey all, thanks in advance for any help/advice/pointing out errors in my thinking.
I have a Home Theatre (HT) setup in my 4m x 8m family room/kitchen space. It consists of an Onkyo 5100 wired to pre-existing built in front and surround speakers with a decent center channel and power sub, which I don’t want to replace. All those speakers are in the 4m x 4m family room side. I have a Sonos Move in the kitchen side of the space which is used for music and Alexa functionality - set timers, add things to grocery list, etc.
I’m about to upgrade the kitchen and want to tie the two sides of the room together, with a Sonos Amp replacing the Move, so that I can a) listen to the same music through the HT setup or b) get the HT audio playing on the kitchen side. Eventually I’d like to add speakers outside which can do a) and b) as well. I’ve read a lot on this forum, the Sonos product instruction and installation guides and other sites but I’m still not sure if I can get it to work as desired.
To start with I purchased a Port. The line out goes to the Onkyo’s aux input and that works great - playing anything on the Port wakes up the Onkyo, it can sync perfectly to the Move in the kitchen and the Sonos One pair in the living room and music sounds great.
The line in for the Port was trickier. The Onkyo has powered and unpowered zone 2 outputs, but using either of them causes the unit to set its sound output to stereo only. Obviously I want full surround sound when watching movies, so that wasn’t acceptable. To get around this, I did some research and ended up adding a Line Out Converter (LOC, commonly used in car audio) in parallel to the speakers attached to the Onkyo’s powered front speaker terminals. That worked as desired, and connecting the output of the LOC to the Port’s line in gave me the front channel audio that I wanted.
I set the Port to autoplay on the Move in the kitchen, and at first everything seemed great. Whenever any audio came out of the Onkyo to its front speakers, I heard it in the kitchen. I could use Alexa voice commands to pause or resume the sound from the HT. But I quickly realized that even with the audio delay set to 75 ms, I was aware of the kitchen speaker sounding like an echo while watching anything on the HT.
Here’s my question - can I put an Amp in next to the Onkyo, connect the LOC outputs to its line in, set it up as “front speakers” and then wire it to my planned new speakers in the kitchen to prevent the delay? Would I still be able to play music across all my Sonos devices including that Amp, so that the kitchen gets synced audio, or does setting up an Amp as front speakers affect that functionality?
(Sorry this got long but with the delay in getting an Amp these days I want to really validate my plan before locking it in to the kitchen redesign)
