Until I have a chance to experiment with more systems, I’d venture to say that MCL82 itself is primarily a kind of “communication  facilitator”, or “glorified IR extender” with an attached speaker switch, which is hard set in advance to the capabilities and IR protocols of whatever master system is specified

I kinda had a feeling about this since the IR transceivers for both MCL82 and MCL30 are very simple inside compared to the MCL2 trancievers

MCL30 transceiver on top and MCL82 below. I guess the MCL82 one has a little extra components to facilitate the IR transmitter for 2 way communication.

Very interested to see what you have come up with 🙂

There are other B&O products where IR issues are related to bad electrolytic capacitors. In most cases it is capacitors near the IR receiver, so they might be within the metal shield.

Other than that have you tried to reapply options settings to ensure that it somehow hasn’t gone to option 0(no ir)

You might wan’t to consider how you are going to control this setup.

If you wan’t to control both the Beovision 11 and the BS3000 with a remote there a few things to consider:

• The AV input on the BV11 can only be assigned to one source name. So if you make that CD, you will be able to press CD and start both the BV11 and the CD player on the BS3000. However you will have trouble selecting another source from the BS3000 (you can do it on the BS3000 button though). Further more you will have a double volume control issue.
• If you instead assign the AV input to a video based source name like DVD or V.MEM you can active the BV11 with that and then select the desired audio source on the BS3000 with it’s source button. This way you will avoid the double volume control issue.
• Instead of using Powerlink out of the BS3000 you can get a fixed volume by using the aux out pins in the AUX connector. This way you only do volume control on the BV11. If this is smart depend on which of the above solutions you take.
• I will also mention the larger alternative which is the Beolink Converter NL/ML which can give you full integration between the BV11 and BS3000. This will of course be a more costly solution and might be hard find in Australia since they can only be found used now.

Hope this input is helpfull, and feel free to ask for more clarification

Very interesting stuff.

It could be that MCL82  protocol is not the same for all the products that can use the MCL82 link room boxes though.

If you look at the picture of the insight of a MCL82 link room box there are code switches to select which Beomaster/Beocenter it should communicate with.

https://forum.beoworld.org/wp-content/uploads/sites/3/beoworld_images/62582/dvnukzpxwaedjk8crbkmw3y8j2esalbl.jpg

This might be an indication that the something in the MCL82 protocol differs depending on which product it is used with. Or maybe it has to do with which type of remote is used in the link rom. I can’t tell for sure, but just something to be aware of

Hello

I would not recommend doing that.

Another possibility could be to get a Beolink Active connected to the IR eye, and the use the two passives as amplifiers connected to powerlink on the Beolink Active.

For this to work you will have to use fully wired mk2 Powerlink cables. This also includes the Y cable adapter you may need if you get the Beolink active with only one Powerlink connector.

Hope this can be used as a solution

Ok good to know. So I will have to look for at least an original SP1/SP2 cartridge I guess

thanks for the info. Very apriciated

My recommendation would be to also replace the clamper belt while you have it open since it is relatively easy to do.

I have never worked on one of these before,

I had one for a very short while which had an issue with opening the glass door. I newer figured out what was the problem before I passed it on to another owner. But my short experience with it is that it is not as easy to work on as the BC2300/BC 2500/BS Ouverture/BS 3000, and the plastic parts just feel more fragile in my opinion.

One thing I did while I had it was trying to remove some of the sticky coating on the surface of it. On other products my experience is that you can rub with IPA until you have removed it and get to a ok looking plastic surface. On the BS4 front panel it was like I could rub down to an ok looking surface, but if I was rubbing to much I came down to a very blank looking plastic surface that was not as nice to look at. So be careful if you try to remove the coating on the front panel

Thank you very much Mark

A follow up question:

I guess this stylus somehow mounts into an existing cartridge, but does that cartridge have to be a SP1/SP2 cartridge or can the one from a SP14 also be used?

Thanks in advance

You are velcome. Great that it worked out

regarding TAPE2: If the other audio sources work it is not related to the option settings. Not sure what It could be though.

Regarding Apple TV and PC it could be something in the connections setup on the TV. I am not 100% sure, but I belivecyou can assign a speaker group to each source, and these two might not have the right speaker group assigned.

Maybe another user can give a better explanation of this than I can

Yes my 6500 is also a recent acquisition, picked ot up yesterday in fact! It was a good price because the Beomaster is not working. I think the MCP is working but I can’t check it with the Beomaster not working at all. I will try it with my Beomaster 4500 and Beocenter 9500 when I get home later, see if anything works.

If you still have a MCL2AV you might be able to test it with that. I briefly had a MCP6500 and as far as I recall I got contact with a MCL2AV

Something in this thread sounded familiar so I looked back into a thread from February where I tried to help solving this issue.

https://forum.beoworld.org/forums/topic/speakerroms-not-responding/page/2/#post-63617

If you still have the speakers connected to both the Beovision 7 and the Beomaster 7000 then please disconnect them from the Beomaster 7000, and make the connection in the main room as shown in the sketch below (shown with another TV model)

And as Guy suggest. Disconnect the Link rooms (with everything powered off) and try to concentrate on getting the main room to work before you look more into the behaviour of the link rooms as these can very well be inflicted by wrong setup/connections in the main room.

Nice that you found a solution for the vibration issue 🙂

Hope you can enjoy this beautiful tv now. I remember looking at the catalogs back in the day and using countless hours looking at the pages with the AV9000 setup with the Beolab 8000 and 6000.

I have a little more info regarding the SW 1.64 for BL Active.

I just aquired two BL Active’s as part of a LOT. Both have SW 1.6 written on the official label. Just to be sure that they were not downgraded I have opened both up, and on one of the chips in the microcomputer is a label with the text Ver 1.64

So my best guees is that B&O has made small software revisions along the way in SW1.6 without announcing it on the product label. SW1.64 is probably from a certain serial number and onwards

I am no electronics engineer either, but I was thinking what about the other caps that are in parallel with C110 like C105 on the same PCB and C101 on PCB 3. Have you checked them? If their properties are out of spec that might affect the total capacitance in the circuit.

Just if you haven’t noticed it in the earlier post in this thread https://forum.beoworld.org/forums/topic/controlling-a-beomaster-6500-via-the-tv-aux-datalink86-pin/#post-51970 there might be a method to intercept some commands in an unmuted state. However it might require you to have a Beovision TV.

@Madskp Thanks much for your offer! There may be a specific version of the MCL82 box that I could use for engineering purposes, and it would be most helpful to have one.  I will return with a model number in short order – perhaps you have one available.

Just let me know. I had another thread about some of them a little while ago if interesting https://forum.beoworld.org/forums/topic/pile-of-mcl-equipment/

With reference to controlling the BM8000 without IR- as it turns out, it may be as simple as attaching a 7-Din Y-splitter to the BM8000 Tape output, and intercepting/inserting all the Datalink traffic that way

OK that’s interesting, and probably also makes for a more stable connection

TK wrote:

I can also properly intercept all component status messages, and emulate a DL86 interface for the BM5000, allowing for advanced integration with other B&O components.  (for the 3 people globally who may care to do do, LOL!)

Great that you acknowledge that from the beginning, and as long as you have fun tinkering with it just keep up the good work 🙂

it would allow me to add an interface from DL80/DL86 with an 8000 series with minimal effort, without needing the special box that B&O sold for that purpose

You will however need a IR transmitter to interface with the BM8000 as it does not have the data connections in the speaker plugs like the BM5000 and the MCL2 compatible systems. B&O had a device called MCL Beolab kit type 1006/1007 to interface between MCL82 and BM6000 and BM8000 with an IR transmitter.

Still looking for info similar to this for MCL82, so if you find anything related to that, I’m happy to receive it.

I do not have any other information than what you can find in the user and installation manuals that are available in the products section of this site.

However I have a couple of MCL82 link room boxes and trancievers. If you could use one of them so you can analyze the signals from it to the BM5000 you can get it for the price of postage. send me a PM if you are interested.

One interesting application for  your findings could be a translator device for Beolink 1000 signals to control the BM5000. B&O made a code converter at one point that has been mentioned in a few older threads, but I guess it is very rare to find. It is mentioned in this old thread https://archivedforum2.beoworld.org/forums/t/714.aspx

If it is the service manual you are looking for it is the product section.

no user guide there, but. Try to ask Multicare if needed. They are normally pretty quick to upload manuals they have available

Sometimes it’s hard to resist when a B&O LOT with lot of black boxes show up 😀

I guess this was from a B&O repair shop as there is several microcomputerboards, presumably for Beolink Active, 7 new in Box IR eyes, 2 used IR eyes, 1 Beolink Converter 1611, 1 AV 9000 Audio kit 1610, 2 Beolink Active 1636 SW1.6, 5 Beolink Video MKII SW 1.5, an outdoor mounting box for IR eyes, 5 Masterlink Distributors and some Masterlink cable.

Next up testing if everything works
