Hi Kevin C, any speakers connected to the Sonos Amp can be configured for Mono in the Amp’s settings. For details on the Dual Mono mode, check out this article. The Sonos Architectural speakers by Sonance are compatible with this dual mono mode.
Can you use a Sonos amp with a single Sonos in ceiling speaker on mono mode?
i have existing single cable runs to 2 rooms that I would like controlled independent of one another through using two amps
Hello TheJoshHarding
Thank you for reaching out to the Sonos Community.
I believe the feature that you are referring to is Dual Mono. Dual Mono is more for the outdoor speakers so it is possible that if you use the in-ceiling speakers then you may experience a audio quality issue but it should work.
