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

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.
So you're saying we should buy additional devices to do something Sonos could do with literally a few minutes of work? Why? 
I agree with splitting left/right into different rooms being odd, but with most in-ceiling setups you want the option for summed mono. It's really not hard, and something any serious multi-room audio system should support.

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.

MB... Easy there buddy. I'm a professional of this industry for 30 years. I know about designing AV systems. It's not a "poor choice of equipment or lack of knowledge" although I did point out that some of these requests are not logical. Here is the bottom line: the lack of mono ability on connects is an oversight. And it isn't being addressed. I know one of the founders of Sonos and will get in touch with him directky and bring up the issue. Clearly it's going nowhere posted here. Not a single reply from anyone at Sonos.

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.

Oh yes indeed. Totally agree with you. And of course, my comment was directed at those who might not know. I hope my instructions were OK - those usually work for me. Time-muncher for sure.

And thanks, Sonovo.  Always helps to have um.. connections.

The last 10% of the job takes 90% of the time (and the rest of the job takes the other  90%!).

Please add mono!

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.

Hello, The SONOS Connect and Connect Amps are stereo units. There is no setting in SONOS to currently change that. I am going to move this Questions to the Share an Idea sections. It will get submitted as a feature request for SONOS to output in Mono. This will allow other users to vote on the idea and submit this to the SONOS Product Development Team. You can try to convert the stereo signal to mono if you like, but it would not be supported. You can also check the unsupported section I searched online quickly and found this: http://www.hometech.com/hts/products/audio/converters/at-mm300.html?key=A27&pk_kwd=AT-MM300&gclid=CMCCobTZ97MCFYZM4Aod4F4AWQ

Cant find the vote site?

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.
