Trueplay for Connect:AMP

I have 5 Connect:Amp's in my home. They are excellent, but the tuning of the sound can be even better. I've been waiting patiently for Trueplay to be added as a feature since it was first announced. When will Sonos add it for the Connect:AMP?

    I own teo connect amps two connect Bridges (4 rooms total). I was sold on the ability to have party mode synchronized throughout the house. There is definitely a latency from room to room that is extremely annoying, even when grouped.
    Unless there's a (relatively rare) hardware fault any loss of sync would either be due to delays in downstream equipment, e.g. because of processing in a receiver, or the simple perception of desync between adjoining rooms caused by the fact that sound takes about 1 millisecond to travel 1 foot in air.

    Fair enough. Yes - I have a kitchen on a Connect Amp and a family room on a Connect Bridge. By the way, I went this (much more expensive) route to get high quality in-ceiling speakers and avoid having speaker boxes (Sonos Play) sitting all over the place. The rooms are within ear-shot of one another. The bridge goes through a home theater receiver, so admittedly, the receiver COULD be causing some latency. So what? I'd still like a way to tune it.

    Its not a bridge you have hooked ot the receiver it is a Sonos:Connect - bridge is a different device so want to avoid confusion there.

    The Connect attached to the receiver could be getting delayed by the receivers processing. I don't know what receiver your using but make sure all DSP modes are turned off and if it has something called "Direct Mode" or similar which removes as much processing as possible.

    What receiver do you have hooked to the Connect. Is it hooked analog or digital to the receiver.

    Sorry about that. Yes, it's a Sonos Connect going to the receiver. And, thanks for the response.
    The receiver is a Denon AVR-X1400H through optical cable. Although the receiver is capable of plenty, its only playing music from through TuneIn Radio station. I was using multi-channel Stereo and there was a delay. With your suggestion I tried direct stereo. Delay was virtually eliminated. So, I tried some other settings and Dolby PL Music seems OK, too. This setting takes advantage of the the 5 ceiling speakers, so, I'm much happier now.
    Thank you, Chris.

    How about licensing ARC (Anthem Room Correction) for the sonos devices? I am currently using multiple Paradigm PW amps with sonos connect and amp units for the sole purpose of ARC - this way I have the best of both worlds - sonos interface with top notch room correction software.

    There are many solutions that do not require controlling the speakers. Representative solutions include D.C.A.C. EX, D.C.A.C. and Advanced D.C.A.C., Audyssey MultEQ, etc. Every retail AV receiver uses one of these solutions to optimize for each of the speakers and the room. They take into account the varying capabilities of each individual speaker, the placement of the speaker and it's relative position to the listener, the acoustics of room, the size of the room (including ceiling height for reflections), and how the speakers interact with each other. At least one solution, D.C.A.C. EX, matches the phase across all the speakers despite any poor wiring by the user. These solutions have been available for many years.

    These AV receivers use wired microphones, which is less elegant than using an iPhone. So Sonos should be able to make it work with an even better user experience, which is the hallmark of the Sonos brand.

    With Trueplay available for multiple devices, it seems like most of the code is already written. How hard can it be to extend Trueplay to the most expensive audio solution Sonos offers?

    There are many solutions to the trueplay issue as it stands.The current standard reply by Sonos is that they can only tune speakers that they have the known profiles of. IE, their own speakers. This would point to a lack of processing capacity, so they work with a very narrow sample. High end amp processors that have built in room calibration have that feature baked into the their architecture, often with a calibrated mic. At the end of the day, Sonos want to sell its products, not support other speaker manufacturers, hence there is no motivation to move ahead and develop trueplay for the connect line. What there is though for the hifi enthusiast, is the option of adding a processor between your Sonos & self powered studio monitors or into your amp. Something like the Drive rack by DBX which is what I use on my system, it works a treat. https://dbxpro.com/en/products/driverack-pa2
