How to avoid sync problems on a ML/NL setup.

17 replies

Hi everyone, I wonder if anyone can tell me if it is possible to do this…

I have a Beovision 11-46 which is connected to a Beosound Overture (in a different room) through a Beolink NL/ML converter. 

Playing audio from the TV on the Overture works perfectly and there are no sync problems when playing on the TV at the same time.

Playing a CD from the Overture on the TV also works perfectly but there are sync problems when playing on both. As I understand it, this sync problem won’t be solved by the introduction of a delay box on the ML side of the converter because the speakers are directly attached to the Overture. 

So my question is if I were to attach the Beolab 6000’s currently directly attached to the Overture to a Beolab Receiver 1 instead, would I then be able to have them in separate groups on the BV11-46. Thus, when listening to CDs in both rooms I could select the speaker group that has both the TV and BL6000’s and when only wanting the BL6000’s I could select a speaker group with only those. Or have I got completely the wrong end of the stick!

Thanks very much to anyone who can throw some light.

You could do as you have proposed, but I can see two potential issues with this:

1. The Wireless powerlink is designed for same room use, and tends to struggle through walls

2. You lose the ability to Play music in the room with the Ouverture, whilst someone else is watching television in the other room.

 

You can however resolve the issue another way.

Are the two products you've mentioned the only products in the setup? and is the NL/ML converter is in the same room as the Ouverture?

If so you can add an IR eye to the Converter (configured with ML Video Master role, IR option 2), set the Ouverture to A.Opt 0, and connect the speakers to the converter rather than directly to the Ouverture. This should result in synchronised sound in both directions as all the speakers are connected to NL based devices.

Hi Martin, thanks very much for your reply... much appreciated.

The house is wired with ethernet which all goes to a patch panel in a cupboard in the hall. That is where I have installed the converter because as well as making it easy to attach the BV11 via ethernet I am also using some of the ethernet outlets to link up the ML network (all kept separate from the ethernet data network). At the moment the only other ML product I have is a Beolab 2000 in the kitchen also attached to ML using some of the ethernet wiring in the walls.

I could possibly move the converter to the same room as the Overture but would then have to run an ML cable directly to the BL2000 due to insufficient in wall ethernet cables in that room. This is also possible.

However, I am unclear how to attach the speakers to the converter? All it has is an ML connection using either a conventional ML plug or RJ45 on one side, to which I have attached the ML network in the house. An RJ45 network cable on the other side, to which I have attached the BV11 and a couple of USB ports. Is it done through the IR eye in which case how does that attach to the converter? Also is the IR eye you mention a BeoLink Active?

Beginning to think that I have an odd NL/ML Converter.

Thanks again for your help... any further light would be most welcome.

Murray.

On the early samples these ports were not labelled - should be active now, if the sw is uptodate.

Please notice that you need RJ45/PL cables or an adater to connect the speakers there.

Not only not labelled but also covered up with a plastic blanking plate! As you say they are indeed there. Thanks very much indeed. I think the software is up to date - according to the device it is.

I can get RJ45/PL cables from Sounds Heavenly but what IR device do I need?

Thanks again... Murray.

The eye (and the cable) are available through a B&O dealer.

I am not sure, if Steve can provide the eye as well - just adk him!

They are still available (same as used for the Core). Also on eBay (e.g. 

Note that you'll specifically need the IR eye with 'JOIN' button as shown in the posts above, not the older type with a TIMER button or no buttons at all, as these are not compatible with the NL/NL Converter.

Also be aware that this configuration will put the TV and Ouverture rooms in sync, but your BL2000 will be out of sync with the other two rooms when listening to CD / TAPE / RADIO from the Ouverture (but in sync when listening to TV sources). There isn't really a cost effective way to resolve that issue - you could add a NL Delay box to put the BL2000 in sync for the Ouverture's sources, but it would then be out of sync with the TV, or you could add a second Nl/ML converted just for the BL2000 to resolve the issue completely, but that would be more costly than simply replacing the BL2000 with a multiroom capable Beoplay product such as the M3, M5 etc...

 

Kind regards,

Martin.

Thanks to everyone who has responded to this. I think I now have a good understanding of how this all works and you have helped me come to a much better solution. Great forum!

Thanks also to Martin for pointing out the idea of replacing my BL2000 with a Beoplay M3 or M5 - what a good idea. Also. turns out we are practically neighbours - I live in Torbay.

All the best to everyone,

Murray.

Sorry to add a rather late addendum to this thread but I am still having some problems...

I have taken everyone's excellent advice and added an IR Eye (with Join) to the BeoLink Converter NL/ML and attached the BL6000's to the NL/ML powerlink socket. I have also bought a BeoPlay M3 for the kitchen.

When playing a source from the Overture the BV11, the speakers attached to the NL/ML and the M3 are all in sync. Brilliant.

However, when I play the sound from a video source on the BV11 the speakers attached to the NL/ML and the M3 are in sync with each other but not in sync with the BV11. Not brilliant.

The NL/ML is set as V Master, IR 2 and has 'Connect to Primary' as the NL/ML and 'Connect to Secondary' as the BV11. I have tried other combinations but they don't seem to correct this problem.

One other strange thing is that on the 'Sources visible on ML' menu the 'Disabled due to ML role' has 'Beoplay M3' in the greyed out boxes in the 'NL Product name' column for the RADIO, A.MEM, A.AUX and N.MUSIC entries. I would have expected to see the NL/ML in there or have I got that completely wrong?

I am sure I have done something stupid and I hope you can point me in the right direction.

 

Thanks again,

 

Murray.
