Hello all. Great that its all comming back togheter. But getting some 404 errors arround and some links like latest post by does not seem to have the right functionallity in all cases.

Would be great with a status from Multicare of what we can expect of things that might not work correctly yet

Great to hear that you got it working to some extent by changing the NL/ML converter ti V.MASTER.

Is there any way to stream to Ouverture? I tried to turn on TV/PC source on ouverture, but it’s not switching to such sources…

LINE-IN is mapped as PC

I am not sure that the Ouverture will react to the PC command. My Ouverture does not at least. Try to map it to video source like V.MEM or DVD

bkslash wrote:

you said that N.MUSIC conflicts with PHONO source of Ouverture – what is transmitted from Ouverture as PHONO? I have a TV connected to AUX and it’s seen as A. AUX on the ML, CD is CD, TAPE i A. TAPE, RADIO is RADIO. so what is PHONO???

The Ouverture has the possibility to control a second tape player and a record player connected to the AUX connector if they have datalink. For that reason the commands PHONO (record player) and Tape2 is both redirected to the AUX connector on the Ouverture and it will show the right name in the display. However if something without datalink is connected to the  AUX connector AUX is shown in the display and therefor the Ouverture will also accept the AUX command.

Because of this the sources PHONO (which is the same as N.RADIO) and Tape2 (which is the same as N.MUSIC) can not be used by any other sources in the ML network, and the Beolink PC2 can therefor not be used as a source in this setup.

For the Beolink PC2 to work in this setup it can only function as a link room (option 6) or else you have to replace the Ouverture to a more moderns system that will work with the N.RADIO and N.MUSIC sources from an other device. This could for example be the BS3000 with the right software version.

I was going to connect my Beogram 3000 also to AUX of Ouverture (with Y DIN-7 connector, port will be shared with TV

Be aware that nor the Ouverture or the BG3000 has built in RIAA amplifier. If you use an external RIAA amplifier and wan’t the Ouverture to control the BG3000 you will need a RIAA amplifier that also can take the datalink signals between the BG3000 and the Ouverture.

I am not sure if it can be a problem to have the TV and the record player on the Y connector. The sound from the TV will be transmitted into the record player and that may be an issue. Other members might be able to elaborate on that.

 

I hope this answers your questions and makes sense?

@Madskp, what is the IPA you mention to remove the sticky coating? I

isopropyl alcohol. I use toilet paper as wipes, and on the systems I have done this on it required quite a lot.

Do you know if Bang Olufsen can still repair these devices ? (BC2, BS5, BL3?) or are they deprecated?

Some dealers with own repair shop might still be able to do so, but spare parts can be an issue. There might also be other repair places that can do this depending on where you are located.

A few inputs:

– BS5 Encore and BC2 probably have sticky coating on the bottom parts by know. This can be removed with IPA (not the beer), but is quite time consuming.

BC2: will probably need new belts for both the wings and the CD clamper. The CD clamper belt I have no seen any source for, so i tried with some different belts from Ebay. Don’t know about the long term relaiability of this though.

BC2: Some members have mentioned that the display can miss pixels if it has been used much

I guess theBeolink PC2 is setup as a link room since you dont have ML conflicts with that?

Other than that, N.Radio from the NL/ML converter conflicts with the source PHONO (which is the same as N.RADIO) on the Ouverture.

My best advice would be to make the line in from the NL/ML converter a Video source to avoid conflicts

Looking at the diagram for the MCL2A the data line has no connection to anything in the relay box which might suggest that the option settings are stored in the IR eye.

I might try with another IR eye to see if it act any different. I belive the one I am using here is one I have not used before, so it could have issues

I have tried Link option 1-6 and do not see any change in behaviour no matter which one I choose, so I am not sure if the options settings does anything for this particular setup.

For the BL1615 it may also be worth trying V.OPT settings, as that is what you would do if there was a connected TV.

I have now tried L.OPT 0, A.OPT 0 and V.OPT 0, and in all cases it still reacts to the remote commands, so guess the option settings does not work in this setup

For some reason the linkroom setup responds to both normal audio commands and LINK audio commands today. Very weird. I can’t tell why it differs today, but might have to do some more long term testing.

Does the IR eye/BL1615 combination accept Option programming? This could explain the change of response. Also, I am not sure whether the Option setting is stored in the IR eye or the BL1615 – you’d have to swap between components to test.

Thanks for the input. I have tried Link option 1-6 and do not see any change in behaviour no matter which one I choose, so I am not sure if the options settings does anything for this particular setup.

I have yet to try option 0 though. That would at least give a hint to wheeter or not the options settings has any effect at all. That will be for my next testing run.

I did a little more testing today.

This does make scenario 2 and 3 in the first post less interesting as there is now risk of conflicting commands.

 

I have also added my BC6 to the ML part of the system, and the TV can be activated from the 1615 link room with normal video source commands

 

I have also tried to replace the 1615 with both a 1611 and 1614 Beolink converter and it seems to work the same as the 1615 except they do not react to video commands.

To be continued…

Perhaps if the audio was fed into a Playmaker, auto-sense on its line-in could switch on connected PL speakers and you would have Beo4 volume control also?  You’d probably need the PM in A.OPT 4 so that it will respond to the ‘link mode’ volume commands that are used to activate the BL1615,

Oh yes, didn’t think of that as an option. That would be an even more seamlessly solution, especially if the BEO4 is programmed to send link commands.

Guy wrote:

and you’d have to avoid the A.MEM command as this would put the PM into Airplay mode.

Yes A.MEM can not be used from the main room in this scenario as the PM also seems to prioritize Airplay over Line in.

And to be complete, even the fully wired PowerLink cable might not be enough to get it working ? https://forum.beoworld.org/forums/topic/beoplay-connection-hub-beolink-passive/

Yes that’s right. This might also be an issue with the BLC

Tignum wrote:

My latest plan is to use a BLC (I do have a ‘JOIN’ IR eye already) and two BL7-4s (that I now have as well). I will see to feed the L/R speakers with Left and Right signals only. I took the BL2000 to the garage for a ‘fit’ and I fear it will be a bit small in the 3x6m space. And now I have a purpose for those 7-4s!

Talking about an upgrade 🙂 But this will avoid those extra boxes for sure (unless you count the 7-4s as boxes).

Tignum wrote:

The BL2000 will move to the garden I reckon (cabled).

Or you could get an extra BLC now that you have the powerbox 😉

One thing that just came to me if you have the Beolink passive in mind. If it makes sense could  you use the BLC with an IR eye as the linkroom and the the passive connected via powerlink to drive passive speakers?

The powerlink cable has to be fully wire for this to work

Also a picture of my messy test setup

I will also do some followup with video master sources and check if other Beolink converters like the 1611 and 1614 will do the same

I have tried now, and the Beolink passive provides 0V on both power and data lines when not connected to other ML equipment

Ok so if I understand correctly the ML power box only deliver the 0.25/-0.25V for the datalines and not the higher voltages on the pink and blue wires?

Yes, it provides the termination voltages for the datalines and 5V to the ML Power + pin. Probably ML Power – is also supplied with -5V but I don’t think any of the common ML devices uses that. As I said earlier everything will communicate just fine if you provide it with the data termination voltage and 5V on the pink + blue/white cable.

Madskp wrote:

What could be the reason for not having the supply of the data voltages in the BLC NL/ML?

I have never looked into a BLC and there is no public schematic available. I don’t know if it is using the old ML ASIC or a discrete solution. In any case I put my bets on a hardware design issue. They either may have just forget about that feature during development or initially it was never planned for the BLC to become a master. Who knows…

Madskp wrote:

Is it because there can only be one unit providing it in a ML network?

Technically you could get away with multiple “Power Master” if they have at least some reverse current protection. Maybe two or three would still work okay but the cleanest way is of course only having one.

Thanks for these answers. Helps a lot understanding how a ML system works.

Interesting. Roughly what I expected to be in there. The 5-pin chip is an unregulated charge pump used for inverting the + 5V from USB to -5V. The smaller ones on the other side of the board are indeed some diodes and two resistors. They are used for providing power to the data lines.

Madskp, B3OHACK3R, would you believe that a BeoLink Passive provides the required MasterLink voltage (as the 1611 does)? I do have one of those lying around. With two CXs and an IR eye (and a remote) I could maybe also keep the number of sound factory boxes limited to two. Regards, Johan

I would think so as it is a link room product like the BL2000, although it has some converter functions in it

[Madskp]

yes that is the same PCB I have in the Ouverture

No flux capacitor! It does have an LED thoughI really cannot tell what the (tiny!) electronics do. If I did not capture a detail that is of use, let me know, and I can try to make a close-up with a camera.

Thanks for the look inside. At least it’s not just an empty box with some wirering from USB to RJ45 😉 but I can be discussed if the components inside reflects the price these boxes are sold at used.

I tried to google the 5 pin IC and it looks like it’s some kind of power regulator

The small 3 legged transistor looking components seems to be some kind of diode
