My right M30***4U10; Unplugged - plug ; 0 w; wake-up (sound) rise from 0-5.8 w to 24w and after seconds (no source selected goes back to 5.8W !
Is that normal for both Gold Phantom speakers (16.4w vs 5.8w) this kind of discrepancy between the two speakers? my last Beolab 9 (B&O) active speakers (700W) had only 0.5 W of standby electric power consumption !
It mean to me that Devialet do not force them to a real standby mode when no music connected to them because 5.8w and 16.4w is very too high to be a energy standby figure number !
Thanks
Hi @
rogmay
Glad to hear things are moving in the right direction for you. I'm afraid I can't comment on the "double resets" as I no longer have a Toslink source I can test my Phantoms with.
Regarding your observations on power consumption I can unfortunately confirm that they are quite normal. The Phantoms are "wake on network", "always on" devices. In order to be remote-wakeable over ethernet, wifi and PLC they need to be in a "higher state of consciousness" than real power save hibernation will allow. I completely agree that Devialet must try to do more here. Having "standby" devices consuming >15W constantly is not acceptable in this day and age. Greta would not approve and nor should we.
The asymmetry is also quite normal. The L speaker is the "master" and the R the "slave". So all stereo audio is sent to the L, which processes, splits the stereo signal and sends the R channel on to its partner. If you check the traffic on your router (Wifi or tEhernet) you will see that the volume of data downloaded on the L is roughly twice that of the R, and that the L uploads a similar amount of data to that downloaded by the R, while the R uploads nothing. Processing and the associated power consumption roughly follow this pattern, the L is simply doing the "heavy lifting". When you're actually playing music it is of course the power consumed driving the speakers (which is volume-dependent) which dominates.
Nevertheless, delighted things are looking up. Keep the faith!

Just a minor comment: I have the ether-net cable connect to the right speaker. In the router (Synology 2600) I can see that the audio is sent to the right speaker - in my situation the right is the master and the left is the slave. My conclusion is that the master speaker is the one you have connected to the ether-net cable. Running DOS2 and very, very happy with audio performance, still on firmware 2.8.1 though...

Thanks @
Anders, you're quite right. What I meant to say is that in a Dialog-less DOS 2 scenario one Phantom is always the master. Where there is a wired input (ethernet or optical) the wired Phantom acts at the master. When the input is wireless (Bluetooth or WifiI) the Left Phantom is chosen by the system to act as the master. Thanks for pointing this out!
On my case both of my Gold Phantom are connected or wired to my router and my Left seem to be the master (always running warmer on standby than the right one).
Before is was running them through wifi/cpl (not connected Ethernet) and the left was always running warmer, and I was
not using any optical input.
So, it is not the input choice that choose the master speaker; in my case the Left was chosen when I chose the second Phantom to paired it in stereo.
My question are: When both Phantom are used in stereo and are wired through Ethernet does they communicate between Left and right solely on Ethernet or use CPL or WIFI too?
If my left is the master and I am using optical input to send musical information (as i do now) ; Could I use the Right
optical input of my Right Phantom to send another optical source (from Devialet App) ? For this Right optical input, does
my Right speaker will be use as a Right master and the left will be a slave? does it work that way ? could I use both optical Input (left-phantom/right-phantom)?
@
rogmay if you are running DOS2 the Ethernet will always be used if there is a path between the speakers. With DOS1 it's a bit random based on what path was discovered first by the devices. Whenever you use a physical input, the device that has that physical input is going to be the "master" for all audio flowing through that input.

Hi @
raph972,
Makes sense but is this something Devialet has documented or is this something you have determined from your own tests? I have seen this behaviour documented by Devialet for the Expert series but not for Phantom. Did I miss it?
@
struts No Devialet is not keen on documenting that type of things. Let's just say I have some insider knowledge of it.
It's right there in the Devialet app: go in the settings, pick a speaker, open "network interfaces". You can read "Note: when your product is connected via Ethernet, Ethernet becomes the preferred network interface."
I'm also sure it's described somewhere in the Devialet help website
Good information, but nobody told me if we connect both optical input one at the left and one at the right Phantom; in that case
when I use the Left optical input the my Left Phantom become master and send the stereo portion to the Right but when I am using the Right one , the Right Phantom gold become master and send stereo infos to the left.
And both input work well no problem at all ? Sharing and becoming master/ slave ? so we could use both optical input?
Thanks

Thanks @

Presumably so, although I wonder what happens when both optical inputs are active?
Unfortunately I don't have even one optical source to test, let alone two.
