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

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.

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.

I disagree. Having mono output makes it a more versatile amp. Connect amp is a great product. It's bridgeable to 4 speakers. Reading other posts, mono is highly desired by many. I'm not looking to debate others, just hoping to have this feature added.

Having mono output allows you to do one thing and one thing only; to use a single Connect unit where you would otherwise use two. That is not the type of "versatility" Sonos profits from. It's not rocket science to understand the economics behind this issue, nor the reason why it isn't going to be "fixed" (not that it is broken in the first place). If you want two channel output through a single speaker from a Sonos Connect/Connect:Amp, buy single stereo speakers that are fit for that purpose.

It's pretty obvious that SONOS doesn't care about its customer one little bit. 3 years, and this glaring issue has still not been fixed. What's the point of this forum if the developers don't care?

They work as designed, so there is nothing to "fix". If you want a single speaker in a room, buy a single speaker with stereo input. That is what they are made for.

I may need to start a new thread but thought this thread was relevant to what I am currently challenged with. In my old house I had a 6 zone Sonos system with Sonos Connect Amps powering a pair of speakers in each room. Worked great no issues and everyone in the family loved it...fast forward we just moved....in this new house we just purchased most every room has a single mono speaker wired with 2 wire from the ceiling to a wall volume control and then 4 wire (but only using one pair) going back to a central location. I was hoping to reuse my connect amps but very much NOT waning to cut drywall and run new 4 wire from each wall control to every mono speaker) do I have any options? I was also willing to replace the mono speaker with dual input stereo speaker (that would accept 4 wire, 2 pairs). The house was build in 2005 but I still can't believe they saved much money on cheaping out on the lack of 4 wire to every speaker.

After doing some research, I think the fact I dont have that 4 wire from wall switch to each speaker really limits me with at least my current equipment. If I sell all my connect Amps and buy just Connects and a multi zone amp, do I have options then? I am struggling on the stereo to mono aspect and the lack of wiring. All of these rooms would be non critical listening but would like to have different zones for my office, bedroom, kitchen, etc.

Any recommendations on what I may be able to do?

Nvm no real mono coming out, ignore my comment.

In the industry, many times one comes up against a wiring mistake i.e. 2 conductor in wall wire and a 0ne point stereo speaker is needed. We have to be problem solvers for these clients who tried to be wired up by the alarm guy or electrician to save a few bucks! Too late to pass additional wires. Sonos Stereo to MONO is the solution.

Please add mono!

After 3 years the answers is still No. Why ? Some may ask , well it's very simple actually. Design you audio system correctly and do not ask Sonos to change their product due to your poor choices of equipment and lack of knowlegde. Anyone here who is complaining about Mono for outdoors. The correct solution is to use a connect preamp and a amplifier which can supports mono output if that's what you desire. Furthermore Sonos amps arent very powerful and suck at driving outdoor speakers in the first place. With regard to using the left output in an amplifier for one room and the right for another room. Are you people reading what you write? Your asking Sonos to basically make a 1 zone device 2 zones. It's so convoluted on many different levels. Basically because you guys are all cheap you want Sonos to reinvent the wheel for you. I'm no Sonos advocate but, they have a product for whatever you want to do. It's all there already. It's no wonder they wouldn't do this. Aside from possible limitations of design. Quit crying about this moronic feature and do it the correct way. If you want a robust outdoor speaker system your going to need amplification anyway. Get over it.
Also I know how to wire resistors inline but this is a time muncher we don't need. I'm running a company where we need to finish an install and go to the next, I don't need to be sending my guy down to the truck to grab resisters and soldering irons only to have some hack looking thing hanging off the back of my box in an organized rack. It needs to be an embedded option.

I still believe that the summed-momo option should be available in software/firmware for ALL Sonos players.

However, if you are using an amp and speakers off a Sonos line output, summing the outputs to mono is simple.  Get two 1K resistors (this value is NOT critical - anything +/- 20%, or even more than that).  Put each one in series with a line output signal lead (L and R) from the Sonos, connecting the resistor leads together at the other end, and then splitting the summed output into an amp (or sending the summed output into one input of a mono amp); this should do the job nicely.  My suggestion is to have the amp nearby to the Sonos unit, but if they are separated, the resistor "network" should be closest to the amp and not the Sonos device. The output level into the amp will drop slightly but quite likely not enough to be any kind of problem.  And depending upon location, you might need/want to shield the resistor assembly somehow, using either a mini-box, some aluminum foil (either of these connected to signal-ground), or the like - this is up to you.

Tech notes:  The reason for keeping the resistors near to the amp is that the Sonos has a low-impedance output (as most devices do); you want to keep the signal cabling at its lowest-impedance for as long a distance as possible. Having the resistors nearest the Sonos device raises the impedance in the connecting cable. For a few feet this probably makes little difference. 

Almost all amps/receivers these days have high-impedance inputs.  If your amp has a low-impedance input (VERY rare), there will be some impedance mismatch and a greater volume-drop, but if it seriously affects the audio, you'll probably hear it right away.

100% Agreed. This could likely be easily accomplished in firmware/software. Why no mono option? Who knows? Sonos? Please?

My original question was actually a bit simpler than that, though. I don't need separate volume control over the two outputs, as I can set that manually (or via RS232) on the d-class power amp. All I'd like is both the left and right phonos to output identical, mono-summed outputs so I can send them to different zones and (post the amp) volumes. Should be easy, but would need a software implementation. Would've thought this would be easy enough tho. Hey ho.
I suppose if the impedance of the Connect outputs is low enough then each side could struggle trying to drive the other so I see where you might want to use a mixer or at least a few isolation resistors. I guess a software change would in fact be the cleanest way to accomplish this.
