My MCL2AV is the version with the TV socket, not the Aux socket, but maybe it would still work?

That works the same yes

I had never considered using a Beomaster though, so am interested in that suggestion.  How would that work?  Would  Beomaster 5000 be suitable?  Beomaster 5000 seems a good option as I believe that one has a built-in phono stage?  Beomaster 5000 will often come up for under £100 on eBay too.

Beomaster 5000 wil not work as it is not datalink86 compatible for connection to the 1611 converter. Beomaster 5500 should work, but I remember reading that some of the early versions did not have a software to be compatible.

Beogram 3000 connects to phono input of a Beomaster (5000, ideally) Beocenter 5000 set up as a link room Beocenter 5000 connects to 1611 via Aux Link (would the 1614 not work instead, since the BS4 can work as the audio master?) 1611 connected to BS4 via Masterlink Would that allow me to operate the Beogram via Link>Phono (or Link>N.Radio)?

It has to be the Beomaster that is set up as a Master as a link room can not serve its sources to other rooms. Also the older Beomasters/Beocenters can not be setup as link rooms.

I do currently have link room speakers connected to my BS4 though – a BL3500, and the Beolink Passive, with a pair of CX50s.  Both of these are set to opt4.  Would the above mean that my link room speakers could no longer work that way?

They would work, but only for the sources from the Beomaster that would be the new Master in the system.

 

Hope this makes sense

Just to start somewhere:

The control of datalink compatible Beogram, Beogram CD and Becord is done via the datalink80 protokol. This is in most cases only available vis the dedicated Phono, CD, tape and Tape2 sockets on various Beocenters, Beomasters and the MCL2AV. One outlier is the BS Ouverture where the AUX socket can function both as a Tape2 and Phono socket.

Control vise a CD socket can control both a Brogram CD and a Beogram Record player. The same goes for a phono socket, but this will not work sound wise with a CD player if a RIAA is installed in the Beocenter/Beomaster.

The datalink sockets on the 1611/1614 converters and the Aux sockets on various Beocenter/Beomasters and the MCL2AV use the datalink86 protokol which is also used for MCL and Powerlink, but isnit compatible with the datalink80 devices.

 

My best suggestion would therefore be to connect the Beogram to the CD socket of the MCL2AV, connect a datalink cable from the Aux socket of the MCL2AV to the 1611 converter and let that work as a main room. Then set the BS4 up as a link room (option 5 or 6) and control the Beogram with Link + CD commands.

This of course has the downside that the sources of the BS4 can not be shared to link rooms.

The MCL2AV in this setup can be substituted with a Beomaster 3500/4500/5500/6500/7000 wich probably should give you control with PHONO commands (I will have to double check that works)

Hope this is of some help for further progress

Working on a 1994 Trek road bike restomod project – but not without some music playing on the BeoLabs! I had two of these for less than 100 euro’s, stripped them and had the cabinets powdercoated. As they are centerchannel speakers I feed them 2xL and 2xR (tweak in the RJ45 wall outlet). They are connected to a BLC that gets the NL from an Airport Express. Happy with my (once) 6000 euro garage soundsystem 🙂

Very nice, and probably much better sound stage than the Beolab 2000 you were planning with at some point.

I notice that you have integrated the IR eye into the electrical fixtures. I am not sure it would fit into the types we primarely use here in Denmark

Btw if you setup the NL/ML converter as A.master you can also use the 1611 converter as an extra analog input for the ML system with the use of video commands (for example TV, V.MEM etc.) to activate the input.

Sidenote: the LCS9000 is used with option 2, only other option settable was 4 but no sound, no reaction on opt 5 and 6

Ok there might be limitations on this since it’s SW 1.0. In an older post on the old forums it was mentioned that Masterlink was not even compatible in the first version, so the option settings might relate more to what it was in the older MCL products

and yes, absolutely positive it is a Beolab LCS 9000 (SW 1.0) as per the label close to the power connector

Thanks. Interesting to know that it was actually labelled as such.

Klaus Stoetzel wrote:

And sure, you are right, the AUX is not regulated .. so in any case I need to fix the IR first I fear 🙁

Yes I am afraid so. Right now I realize that the volume regulation issue you have experienced is because you can not volume control the LCS9000 itself. The LCS9000 has a circuitry to compensate for volume differences from the amplifier in the BM5500, so if you raise the volume on the BM5500 the LCS9000 will try to compensate and lower down the volume (i think in 4 steps).  This is so it is possible to do individual volume control on the LCS9000. So you might only have issues with the IR eye.

Welcome to Beoworld, and glad you appreciate this thread 🙂

For starters, you call the link speaker LCS9000, and the SW 1.0 tell me that it is an early version you have. Out of curiosity is it actually labeled LCS9000 on the speaker? Just asking as I have not yet seen it printed on one.

Klaus Stoetzel wrote:

Would the special DIN cable mentioned upthread probably allow the LCS9000 to perform better, taking the amplifyer out?

If it is the cable pinout mentioned in this post https://forum.beoworld.org/forums/topic/bl3500-and-the-mcl-pl-connector/#post-44540 then yes that will bypass the need for the amplifier in the BM5500 and work just as a not volume regulated line out signal for the LCS9000, so the volume control is only on the LCS9000

Klaus Stoetzel wrote:

The lack of IR on the LCS9000 should require the two caps to be replaced, right?

That might be the case yes. This thread has a great guide on replacing them https://forum.beoworld.org/forums/topic/beolab-3500-sometimes-responds-to-remote-control-sometimes-it-doesnt/#post-29738

Before you do that however you might try if it has been set to option 0  at some point (no IR). With a Beolink 1000 you can press Link + 6 + Store and see if it responds with Option 6 in the display (option 6 is link room with both Audio and Video commands).

Klaus Stoetzel wrote:

The DIN to Jack cable (as from SoundsHeavenly) would be my best/easiest bet on hookup to i.e. S10 srtreamer (after the IR fix obviously)

That is an easy connection yes. However you have to use the Menu + 0 + 4 +Go combination to activate it and have no volume control with the remote + any remote press will put the speaker to standby.

I would like to recommend some of the other options mentioned in this thread where Masterlink is used, however with the SW 1.0 I am not sure how much will work and how much will not.

Please let me know if you need other input

Stefan Leuenberger wrote:

But how to connect the NL/ML converter to the rest of my Masterlink setup (3 Beolab 3500)? There is only one Masterlink socket on the NL/ML converter.

Actually there is 2 where one of them is a RJ45 connector. So you can use a RJ45 to ML cable. Another option is to use a ML junction box and split some ML cables and make a Y connection between them

I’d presume most of the audio/video are just pass-thru, and the boards mainly relate to the datapins on the different buses.

Just for fun I have tried to look at the traces on some of the ports, and indeed the audio and Video parts are just passthrough between the two corresponding connectors in each column.

Datapins from AUX and PL ports seems to be connected as well as the ground connections on them indication that the AUX ports are for datalink86/MCL data signals

The apl1 and apl2 connectors seems to have pin 6 and 7 connected indicating that it is datalink 80 for connection of a Beocord/Beogram/Beogram CD as they can use both pins for data.

The Svarct connections (AVL) also have all it’s datapins connected although as far as I can tell from the photos pin 8 might not be passed through between the two scart connectors

Hope this can be useful for further investigation on what this thing was used for

Thank you very much. I have ordered one of them. Most probably I will come back with more questions. I have an old fashion Master Link only system with Beolab 8000, some Beolab 3500 steered by Beosound 5/Beomaster 5. Recently the Beomaster 5 became unreliable and I had to reboot it very often. Because of that I would like to replace it with the Beolink ML/NL. I hope I can connect my Apple Airport Express and use it as the Music Source (from iPhone or iPad) and also my Synology NAS.

One thing you will need if you replace the  BS5/BM5 with the NL/ML converter is a way to supply the correct voltages to the ML system as the NL/ML converter cannot do that.

You can either use a ML powerbox (if you are able to find one) or a Beolink Converter type 1611 where you only connect the ML side

Looking at the Beosystem 10 product page there seems to be some kind of error where the documents should be. Multicare is in the proces of updating the product pages and adding manuals, so it might show up at some point. You can also try to contact Multicare through the contact page and I am sure the will be happy to help you find the manual if available ( I think it was available before the update)

For arround 7 years ago I purchased a complete Beosystem 6500 in white. The MCP 6500 main PCB was in bad shape due to leaking batteries and had been stored away until now. Thanks to fellow Beoworld member Madskp who has supplied me with a doner MCP, I now have a fully functional mint white MCP complementing my Beosystem 🙂

Great to see that my donor parts could help make one working and by the looks great looking MCP 😀

Hopefully you can avoid future battery leakage

You should use the 2 pin connector for connecting passive speakers.

The third pin carries data and power for use in a multiroom system (MCL)

Regarding removal of SMD caps see my two last posts here https://forum.beoworld.org/forums/topic/beosound-9000-ir-repair-pcb-14/#post-55674

Especially the youtube video is very usefull.

 

regarding the flat cable rip an alternative could be to solder two thin wires directly to the solder blobs on the motor and find the corrosponding signals on the PCB and solder the other ends of the wires there. I did that with a harddrive once to get it working again. Not sure if there might be any downsides to this method other than routing of and space for the wires

This unit is very intriguing.

I have been looking at the picture of the front several times since you posted, and I am wondering about the 3 columns of connectors named 1, 2 and 3 for both AUX, PL and AVL, and also the labeling master and slave in the bottom of the scart connectors.

Can you see if the connctors in the single columns (for example 1) are directly connected internally so they work as a passthrough or if they go through some circytry on the board? This could indicate wheether alle types of connectors in one column. are both master and slave

I wonder if the IR sockets might be for direct use with the 7 pin DIN IR connectors on the round IR eyes for Beolink active and Passive.

Nice writeup. There is something about those blue B&O instruments. You can almost feel the quality of them.

I had a student job in the drawing archive in the R&D department of B&O for a year back in 1996/1997. Those blue instruments were all over the place in the R&D department back then.

I have a SN14 power supply myself that I have had for almost 30 years now and had much use of. It might need some servicing by now though as the voltage regulation is a little unstable now.

I also have this box with a disassembled  TG7  and an extra main PCB that I got from my father. He has no idea what might be wrong with it, and its not high on my priority list. But maybe someday 😀

For that use case the 1611 is the correct option.

it is possible to use the Beosystem 2500 with MCL by use of a Beolink Passive or ML-MCL converter.

It connects to the Beosystem with powerlink and converts to MCL

And yes a 1614 can not be used in this scenario
