Can the Amp and Connect be told to output mono rather than stereo? Using with mono ceiling speakers in bathroom and kitchen.

Single ceiling speakers (already bought) being used in the bathroom and kitchen. I need to sum the stereo signal for those, as I listen to a lot of soul which is 'dual mono' i.e. drums on left, everything else on right. Can the output be set to mono?

Seems strange that Sonos can do mono for play 1, One and 3 speakers but can't push it to the Connect and Amp lines too.

If I was the Community manager I'd ask someone at the next staff meeting about that.

Of course after a few questions like that I'd probably be as unwelcome at Sonos meetings as I was at my old job.

I imagine they don't allow it because installers would be using a single Connect:Amp with mono speakers to cover four rooms, instead of using two Connect:Amps. Sonos has never made it easy to cut corners, for instance, there have never been headphone jacks on units lower in price than the Connect.

The one thing I don't like about my Gen 2 Play 5 is the missing headphone jack, I didn't do my homework and bought it instead of finding a Gen 1 that had the jack. I guess it is good business to remove rarely used features but it is frustrating.

If I was an installer I'd just specify a Connect and add an external amp that had a stereo to mono switch.

Sigh.

If driving a single speaker from a Connect:Amp is all you want, maybe you "installers" should read up on a little thing called a single point stereo speaker.



Single Point Stereo Speakers can be a solution, like in new construction (I'm doing a house now with SPSS in 2 different small rooms, each with their own Connect Amp.). But SPSS require 4-conductor wire (left and right channels). Very rarely (never) do you find 4-conductor wire ran to a "single point" in old construction (I've never seen it in any of the houses I've worked on.). Mono is the answer.
Stop repeating your same drivel, it doesn't apply here where people are looking for a solid solution.

Only if the home owner wanted the same volume in these 4 rooms or wanted to use antiquated in-wall volume controllers. 4 Connect Amps would be the solution in your scenario, so that the home owner could easily control the volume of each of the 4 rooms through the Sonos App.
It is not about cutting corners. It is about doing what the home owner wants or, in old construction, what we can with what we are given to work with.

Which brings us back to my earlier suggestion above, a Connect and external amp that can mix the Stereo input to mono for the speaker(s.)

Yes, that is one solution to make the existing Sonos mono. But the majority of us here are making our case to Sonos to put the Mono functionality in their Amps so that we don't have to buy 3rd-party equipment and can keep the configuration simple (less equipment).

SONOS SOLVED THE MONO ISSUE!!!

The new Sonos Amp says this in its Specs: "Speaker output connections: Banana plugs (2) capable of stereo or dual mono sound." https://www.sonos.com/en-us/shop/amp.html (click the link and then "Specs")

Yes! Finally a solution!

Mahalo to all who helped Sonos understand the need for mono!

Excuse my ignorance but does Dual Mono mean that you cannot drive just one mono speaker from the new Amp? I am one of the many many people who has single, mono speakers in a variety of bathrooms and I was just about to purchase a bunch of Sonos kit to drive them but if the new Amp can't drive a single monos speaker I'll have to use another manufacturer's solution. Thanks in advance!

No, it would be able to do that. Both the Left and Right speaker ports on the amp will produce the same mono channel. If you only want one mono speaker, than you only would connect a single side.

I would note though that you might want to consider using a single amp for two or more bathrooms, if you are ok with them having the source and adding external volume controls. Alternatively, sticking with the single speaker per amp plan, I'd consider getting stereo input ceiling speakers.
