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

By all means I am not trying to debate you or anyone else who may try to justify lack of mono function. I understand your point about "corporate greed" and selling more units. In your example, 2 Connect:Amps are NOT a solution. Even buying a dedicated amp for each speaker is not a solution, so more Connect:Amps do not help me get full sound for each zone.

Again, I'm not sure what you want me to say. Your particular circumstances are unfortunate.

By the way, one person's "corporate greed" is another person's "corporate survival". Sonos employs people too. I hear they even pay them a salary.

I currently live in a condo rental with in ceiling speakers. One in bathroom, one in bedroom. I also have two small outdoor speakers not facing in the same direction on my patio. I have four reasons why a 4-Ohm stable amp can drive 4 speakers (8-Ohm each) with mono sound. So now I should replace 4 speakers in my rental due to a signal output setting?

I'm not sure what you want me to say. Anecdotal stories about your personal circumstances are not applicable to corporate decisions on how to maximize profits. Fact is, if Sonos allowed mono output, every installer in the world would cut costs by using a single Connect:Amp to drive 4 mono speakers in separate rooms instead of 2 Connect:Amps. Your situation doesn't change that fact.

Sorry jgatie, but you are incorrect. Those of us who are installers would never use "a single Connect:Amp to drive 4 mono speakers in separate rooms instead of 2 Connect:Amps". Why, because separate rooms each need their volume controlled separately. It's old school to use a physical volume control and all my customers want to control the volume of each room through the Sonos App. So, like others that have posted here, having a Mono option would be extremely useful.
Regarding corporate decisions based off money: NOT adding the Mono feature is driving customers and installers to buy other solutions that are NOT Sonos products, so...
Aloha

The big picture: The need for Mono isn't about the number of Sonos Connect:Amps, but rather the number of speakers in a room and their configuration.

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.

I found this. Seems like it will work.

I am not an installer. One's ability as an audiophile has nothing to do with this simple age old functionality. I have two outdoor speakers, 2 in the den, 2 in living room, one in bathroom, and one in bedroom. I use monoprice speaker selector switch. No, I do not want to change all speakers over a switchable output feature.

We "installers" all know (for the most part) exactly what a SST or "single point stereo" speaker is. We also know that it typically cost twice what a standard speaker costs. There are many spaces where only 1 speaker can fit (bath) and the customer is budget-conscience (thus using Sonos).

Additionally we also know that unless a space is a "critical listening space" (i.e. the listener will be equidistant from each speaker, stereo is not a good fit for a distributed audio system. Background music should be the same experience for each person in the room if that's the intended application. Unless you don't mind the vocals coming out over your guest's head while the rhythm guitar (for example) is coming from the speaker over your's.

This is precisely why MOST manufacturers of audio distribution amplifiers offer an option to either set mono or bridge mono.

School's out.

You resurrected a 10 month long dead thread for that? Business must be bad. :?

Not at all. I resurrected it because I just ran across a situation where I have a budget-minded client where this situation applies and had to reach out to Sonos to find out this is the case. AND it's been out there this long ..still unresolved.
Just trying to call Sonos' attention back to it. So thanks for noticing!

People have been asking for this since the very first ZP100 and there has never been a hint that mono output is coming. Given this, my advice about reading up on a little thing called a single point stereo speaker still applies.
