Hi there,
I have 7 pre existing ceiling speakers spread out through my upstairs floor. 2 in a screened room. 2 in kitchen. 2 in living room. 1 in master bathroom. Each are has wall mounted volume control with all 7 speakers feeding to a receiver in the living room. I’m interested in connecting through Sonos but unsure what unit or units I would need to do this. Any help would be greatly appreciated.
