Hi all,
I have a pair of Beolab 18 speakers paired with a Beosound Essence Mk1. I am considering upgrading my setup to a Beosound Core to take advantage of:
Questions:
Looking forward to your answers.
Best regards,Thomas.
ThomasBrorsen:Questions:1.Is the S/PDIF out on the Beosound Core and DAC in the Beolab 18 any good?2.At times I Airplay at the same time to both my Beolab 18 and Beosound A6 from my Mac. In the current setup the audio sync in this is near perfect. I am concerned if I move my Beolab 18's to S/PDIF that there may be sync issues (I have experienced this with other S/PDIF products). Do you know is B&O have adjusted for S/PDIF "lag" in the Beosound Core to ensure audio sync?

Hi Elephant,
Happy to hear that the audio quality is good.
The 18s and A6 are in adjacent rooms, so any audio sync issues would be an annoyance. Anyone else have a setup like this?
Best, Thomas.
Elephant,
See from other posts that you have a homepod. Could I convince you to set it up next to your BL 20s and airplay to the HomePod and BL 20s simultaniously? This should be able to test any potential lag stemming from the optical connection.

elephant: That is, the lag appeared to be in the HomePod’s processing ....

Now, that is interesting....on a sidenote!
Looking forward to see tests with AirPlay 2 multiroom to different AirPlay devices.
How will they handle this delay due to heavy processing in the HoneyPod?
elephant - could you try airplaying (from the Mac) to the HPod and to an ordinary AirPlay receiver/device?
I wonder if there is a time difference there too?

There is a tv - and there is a BV
P.S. I suppose your first test included the BL20 connected via optical out to the BL20, which was the reason for expecting the 20’s to play later.
’....the BL20’s connected to the Core....’.
it should have been ;-0

I’m sure everybody here is aware of what you bring to this forum !
Having someone being able to answer others questions (since such a long time) by doing tests on its own setup is just invaluable!
I think it’s worth the wait, 48h or whatever the time you give to us
Relax friend - I was not offended !
I had genuinely forgotten MM's request
Millemissen: elephant - could you try airplaying (from the Mac) to the HPod and to an ordinary AirPlay receiver/device? I wonder if there is a time difference there too?
So MM this is not quite the test you asked for ... I will do the that too with at least an A1 and maybe an A2.
However I was thinking back to the original test ... and thinking we should not be surprised; it is after all what NL was designed to do:
Deeper > Core - join - Essence
^BL20 ^BL11+BL6K
Yes, the audio paths were different, but none the less it was all B&O.
So my mind came up with another combination:
Mac Airplay > Core ^BL20
+
Mac Airplay > Essence ^BL11K+BL6K
The above test isolates the two B&O systems to their own worlds ... both (hopefully) simultaneously receiving an Airplay signal from the Macbook Pro, and both processing independently .... one a daisy chain path using optical; the other a daisy chain path using PowerLink, and through 3 speakers
Admittedly I only listened carefully to the Left side ... so therefore I was comparing Left BL20 with BL11+Left BL6K.
And the answer ... seemingly no delays ... on certain notes if felt the emphasis came from one speaker or the other, however in general I seemed to be hearing a common sound :)
Now later in the day we try some BlueTooth Airplay, since the above was WiFi Airplay !

elephant: Millemissen: elephant - could you try airplaying (from the Mac) to the HPod and to an ordinary AirPlay receiver/device? Do you mean an A1 or an A2 ? Sure - no problem ! Give me 48 hours :)

I should have known (remembered) that Airplay and Bluetooth don't mix.
So the A1 is certainly pure BlueTooth ... as is the A2.
So yes, I can pair them to my MacBook, but I can't simultaneously AirPlay to anything and send a BlueTooth signal.
I have to connect the BlueTooth as being the local speaker, and when I do that I can only have the local (blue toothed A1) or have Airplay BL11+BL6Ks & BL20s ... but not both.
So Dear MM, I don't see how I can meet your request, other than to AirPlay the HomePod with the Essence instead of with the Core.
I am not sure of the value of that, given that I did do the separate Airplay in parallel to those two speaker sees ....
So MM, given my setup, could you be a bit more specific about what (and how as I may be missing / assuming something) you want me to do the test ?
Thanks !
@elephanth
No hurry - I don’t mind the ‘lag’ - I’ll also be here in 48 hours ;-)))
Since it was ‘on a side note’ - ‘off topic’ so to speak, I am patient.
What I wanted to know is, if there is any lag between the sound coming from the HomePod and e.g. a M3/5 or a Playmaker (any device with AirPlay support), when fed simultaneously (via AirPlay) from the Mac.
That is, if the processing going on in the HPod introduces a lag to the AirPlay stream by itself?
Hope this is clear.
By the way I second the posts of other members - you certainly do a great job here with your testing - kudos!

Maybe the HomePod behavior will change once the AirPlay 2.0 sw is launched? Also, the rumor has it that 2.0 will buffer complete songs - should be possible to sync all devices in a multi room setup perfectly if they all used AirPlay 2.0?

elephant:However as an hypothesis from the two tests:1. Core and HomePod = lag2. Core and Essence* = no lagI would conclude3. Essence* (PlayMaker 2generations on) and HomePod = lagHowever I will verify that *my Essence is a mk ll

Yes, but it won’t change the delay in the HomePod, which comes from the processing of the sound there.
(Which. - by the way - could be variable, according to how it has to process.)
To have syncronized sound from all devices would mean to balance this delay in the other (2.0) devices to what is played.
It might be possible, but difficult, I guess. And the big question is: how noticable will that be in the end.
Note! The release of AirPlay 2.0 is heavily delayed, maybe they are struggling with problems like this?

Interesting to see that the most high tech company in the world has some problems to create a multiroom system... We wait for years to come from ML to NL, but all we can see is that the solution was functional from day 1 without sync issues.
