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?
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!

Aloha!




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!

I don't know if this solutions will translate to everyone's setup, but you can connect the speakers in "series" to a single channel; left or right, on the connect:amp. Then, go into room setting and push the balance to the side you are using.



Just be mindful that the overall volume will be lower as the impedance will be higher on the single "circuit".



I hope this helps!
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.)


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.




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.
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.
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.
Op you forgot to ask sonos to let you label the right speaker bathroom and the left speaker kitchen. Lol
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.
Anyone have experience with Audioplex Monomixers used with Sonos Amp?
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!
We had a customer, just this week, looking for a product to make his speakers 'wireless'. A stereo-pair of Connect;Amps would have been perfect.
Problem is that no one from Sonos is apparently reading this, or they just don't care.



I was fairly invested in Sonos equipment at one time (in spite of their relatively huge price premium), and the lack of action on this issue made me change directions.  I ended up getting an AV receiver with multiple zones and Apple AirPlay support.  The receiver also has a mono option for zone 2 because someone there evidently realized this need.



So instead of spending a bunch of money for a dedicated Sonos amp for my back yard on top of a Sonos Connect for my main receiver and separate Sonos speakers for every room that I wanted music, I bought a new receiver that handles my living room AND my back yard, and used the Apple TVs I already had in the rooms as AirPlay devices with relatively inexpensive amplified speakers. 



Don't get me wrong - there are plenty of annoying issues with Apple AirPlay, and I would still pay a premium for Sonos, but I won't even look at them again until they address or at least respond to this issue.  If this requires hardware changes to implement, at least let us know.  If it can be done in software, then there really is no excuse for no action or response from Sonos or over 2 years.
Agreed here as well.  Mono for me would be useful so that in a kitchen/diner or a bathroom/ensuite I could have a single speaker in each and provide a 'full' sound feed rather than just a left or right.  I don't need separate volume control.
Agreed Adam. Wish someone was listening.
The more you ask for, the more the engineers have to do. You are asking for the functionality of two units in one with a separate volume control. That's not cheap to do. Requires a completely new design. Mono is already available in the portables. Just needs to be added to connects. Your issue can be resolved by setting the gains differently on the power amp powering each zone. If you are using a powered connect or a standard receiver, then you have to just buy two connects. This lack of mono is killing custom installation companies like mine .

Balance is not the same as separate volume controls. As you raise one side with balance, you decrease the other. It's just not the same thing. This requires rework. Furthermore it canobalizes the companie's sales even if they were to do it. The solution to two zones is two units. You are trying to save money. The lack of mono has no real solution.. I'm not trying to knock your idea, but it's diluting the original request which is quite important and desperately needed. If someone from Sonos reads this I want them to see a simple and necessary request. Nor a bunch of different ideas thrown at them on a single post by people who really aren't product engineers. We need mono capability on Connects. Please.:. Someone from Sonos let us know you are at least reading this. This thread was started a long time ago.
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.

It doesn't take anything more... Its actually just connecting the two Volume controls to the balance... If you want the Mono left channel up, turn the volume up and the balance slides to favor left. If you want right mono as well turn its volume up, if left is already up it just slowly banaces adding right... Its a simple algorithm they could add with mono to allow for two volume controls instead of one. Most people who use MONO use it as they are using speakers in separate locations... Why not allow for separate volume control. Keep it as one box just separate volume control... For example mine are labeled Side/Front Yard... Obviously the same thing would have to play on both speakers, just the volume control would be huge!

Yes on Mono Control! - Plus it would be awesome to allow individual volume control for each Left and Right as most likely, like in my case the speakers are technically completely separate locations!

Well, Adam Brown below is asking for the exact same thing, yet uses an additional device (Non Sonos) to control the volume. Im just simply asking for your request, plus asking in addition for simple volume control, goes hand in hand with the Mono. Sonos my guess would want to keep Sonos with in Sonos. Why add more devices to something that doesnt need it. Its not even close to "Canobalizing" their sales. If so, then your simple request for Mono is what Canobalizes the sales. Mono allows for separate locations for the L/R outputs. Volume control is just a simple conjuntion with the Mono feature. Sorry you feel your idea Canobalizes their sales.



Balance. Balance is actually Volume control between the two Left and Right. Its the EXACT same idea. To make separate volume controls involves NO hardware additions. Its the simple ability of combining the Connect Amps Main Volume Control with the Balance Volume nob. I do it all the time with mine now, just have to jump into the settings to adjust it correctly. My volume/balance request in addition to Mono is a basic and simpe IFTTT procedure.



My guess is, Sonos wants to keep things with in their own devices. Plus as a consumer, we would rather purchase one device, instead of having to purchase more than one to do a simple task. Why add more devices to the mix, which cost more money... 



My request is a VERY SIMPLE, well paired request with your Mono Request. Your clients would appreciate this feature! 🙂
I would use a Connect without Amp and connect it to an OSD AMP-120. This Amp will run 2 pairs of speakers, can run mono/stereo/Bridge, has an override second input and is auto-power on/off via signal detect. $99 US + Delivery. Sweet device..



Must agree though that it would be nice to have even a simple switch on the back to select mono/stereo output. I don't think you can do it as a solely software fix due to the local analogue input??


Someone installed 6 basic(assuming 8 ohm-nothing in specifications) 6.5" ceiling speakers in 6 different rooms of an office building that I am using.  1 speaker in each room with each wire run separately into the server closet.  Could I possibly use the OSD AMP-120 in mono mode with a SONOS hooked up to it and then run to a speaker selector(w/ volume control) for each rooms single speaker.

I'm installing a big Sonos system in a friend's house. Without a mono option the wiring is far more complicated: stereo input ceiling speakers, local impedance matching volume switches, what a nightmare. Thanks for skipping the obvious Sonos. Same camp as Mr. Olson, took it for granted that ceiling speakers and whole house audio would be familiar territory for these guys. With odd rooms and hallways and bathrooms, etc. why would they assume stereo is appropriate everywhere all the time? Odd...

fully agree - SONOS PLEASE READ THIS THREAD AND TAKE ACTION !!!

That would work safely but unfortunately it's an $80 discontinued item. Sonos just needs to do this. This feature can be added for almost zero extra cost. It already exists in the play units. It's just getting someone to actually listen.
