So now we know how to set up the 'Delay Box'.
Has anyone already used it?
Greetings Millemissen
There is a tv - and there is a BV
Currently using it in the shop and it works great!! Just as you would imagine.
Ah, you know... A little B&O here, a little there
This thread has been viewed 170 times - but noone (except BeoMegaMan) has tried this box.
Makes me wonder why people complained about the sounddalay!
The guys in Struer created a solution....that noone uses.
Grrr! Millemissen
StUrrock: Scarce R&D resources could have been better used elsewhere me thinks
A similar model of the Mastelink Delay box has been available for approx 2 years.
To coop with the longer delay caused by the BeoLink NL<>ML converter and the different amounts of delay time for different sources, it needed an update to become more "intelligent". No necessity to re-invent the "wheel ", just some very effective "wheel balancing" ...
StUrrock:There was no need to make one! Other manufacturers devices do the job just as well, ok they may not have ml socketry!

Hi StUrrock,
could you please be more precise, about "which other manufacturers devices do the job as well"?
And how would they work in a NL/ML-setup WITHOUT "ml socketry"?

Thanks for your clarification.
I am sure these solutions works, but they aren't user (or installer) friendly, you must admit.
So we should be happy that Bang & Olufsen has made some "wheel balancing" with the new box.

It is so - this box 'only' has an effect on rooms connected via ML. The audiosystem MUST be in Option 0 (with no speakers).
This was not described in the part of the info, that I published.
I just wanted to push the discussion on this subject

Absolutely right!And there is a real BIG difference compared to simple 3rd party delay-boxes.Since every ML component "knows" the source of the sound (either audio or video)the B&O ML- box can handle (= delay) signals differently corresponding to the source.This avoids "double delay" for the sound of video sources sent to the ML system ...That's what I ment, when I posted "the box had to become more intelligent" in my previous post.
!! It is mandatory, all 3 involved components (V1/BV11 + NL/ML Converter + ML-Delay-Box) havebeen updated to the current SW level - different SW levels won't coop.

Hiort:My delay problem is that the sound in linkroom is "after" the sound from mainroom when I play my BV11. So I get an echo effect in the house. I have an NL/ml converter between BV11 and the ML system. Will a delay box be able to cure that?

No, the delay box would even increase the delay in this situation. What you need is a delay on the NL side. The delay box is just for ML.
There are some settings in service menu of the TV regarding this. Something like delay cabled and wireless. But I can't remember well...

Yes, that is what I thought.
Since the ML sound is delayed compared to the TV sound, I figured I somehow need to reduce the delay imposed before the sound is put out on the ML.
I tried reducing the delay in the Service Menu, but could only bring it down from 60 to 30 ms (my TV is wired) and it was not enough. Think I have to look into the NL/ML Converter, that probably is adding delay when converting the signals into the ML.

The problem is that the conversion from the digital NL stream to analog ML output will always take some time. This cannot be decreased in settings of the NL/ML converter. Have you tried to increase the delay in the service menu of the TV to maybe 300 ms or more?

Yes, I tried to increase just to test, but it (of course) got worse.
Problem solved!
The delay has to be the same on the BV11 and the NL/ML converter. Of some reason they had different values. When I made sure I had the same values on both it worked fine. No delay.
Hiort has kindly referred me to this thread. I am considering to buy a delay box, but not sure whether it would fix my issue. My setup as below:
BV7 with ML/NL converterBV5 with ML/NL converterA9
When playing from the A9, everything is in sync (DLNA, Deezer, TuneIn).
I am trying to distribute the audio to other rooms when playing music videos on the BV7 from an ATV4. It works to distribute it to the A9, but it is not in sync. Would a delay box address this issue or would my video/audio on the BV7 get out of sync by doing so?
There is unfortunately nothing you can do about the delayed audio from your BV7 video sources, as this is a result of the time taken for the converter to encode the audio, send it over the network, and then for it to be decoded it at the other end by the A9.
You could in theory connect your speakers to the converter instead of the BV7 which would resolve the delay issue, but of course you would then have a delay between the video shown on screen and the audio which would be even more of an issue (and you would also lose the surround sound decoding abilities of the BV7).
The delay box is useful if you have an ML based audio master as well as the BV7, in addition to the converter - for example:
BS9000 ----- NL/ML Converter ------ Delay box ----- BV7 ===== speakers
(where ----- is a ML cable, and ===== is powerlink)
In this example, the delay box adds the same delay to the signal before it reaches the BV7 as the netlink transmission between the converter and for example your A9 creates, such that the audio from the BS9000 would be in sync when played on both the BV7 and the A9, and because there is no video involved there are no issues here with lip-sync.

steve1977:thanks, very helpful! if I were to use the line-in of the ML/NL to connect with the ATV (but BLs stay connected with BV), would audio be in-sync? from what I read in your message, this would probably work?

The simple answer is that there is no way to distribute the audio part of an ML video source, whilst simultaneously keeping the audio and video in sync with each other.
Got it, thanks. I had actually changed my question to an audio-only question. If I were to connect a second ATV or an Airport Express to the line-in of the ML/NL, would I be able to keep the audio in sync between the BV7/BL and other NL sources (A9 et al)? Idea is to make the BV7 airplay-capable and allow distribution of an airplay source (e.g., Spotify).
To add to this thread as a resource to help others:
I found that in order to get my ML/NL Delay Box working correctly, I used wired connections (not wireless) for all NL devices. Also, I had to set both the Wired and Wireless settings to 50 for the BeoLink Converter in the NL Management screen. My BeoLink Converter originally had the Wireless delay setting at 10,000 ms. I had to change that to 50 ms. Doing so automatically changed the ML delay setting (under the NL Management screen) to 143 ms -- which is close to the ML/NL Delay Box's default setting of 149 ms. It now works perfectly.
