One extra thought. I have not come across any any info on how the code switches in the MCL82 should be set if it is used with a Beomaster 8000, but it might be in a manual for the MCL-Beolab kit if that is to be found anywhere.

I would expect that certain IR wavelengths would make it easier for the receiver to pick up the signal. At point blank range, there is likely enough “bleed through” or overlap for not perfectly matched parts to still work. I recall reading the B&O had issues with sunlight falsely triggering some systems and having to all physical light filters. I don’t remember what systems were affected, but removing any filters for testing might help. The blue LED comment doesn’t make sense to me since this is at the wrong end of the light spectrum. Unless blue was used as a indicator for a human to see the activity without interfering with the IR.

Thinking of it I think I saw a picture of the IR emitter at one point and it was encapsuled in a little black box. Maybe it has a window with blue glass on one side.

Maybe I need to expand my eBay searches to include “unmarked B&O black box”. 😉

Oh yeas that could be a lottery ticket. However without markings most Ebay sellers might not even know its B&O.

Interesting test. Have you considered hooking up a oscilloscope and comparing any of the signals to the code tables in the service manuals?

I do not have an oscilloscope, so no go there.

Glitch wrote:

I’m in a similar situation with having some, but not all that is needed to run a good test.

I might be willing to sell the MCL Beolab kit to you if you can find use of it, and judging by some of your threads, you have some BM6000 and BM8000 so a lot better basis for use of it than me. PM me and I am sure we can find out something.

I think that I’m getting motivated enough to buy a Beomaster 5000 and MCP5000 for test purposes. It wouldn’t be the first time I’ve done something like this where the tail is wagging the dog.

I am also considering getting a Beosystem 5000 (I already have a Beocord 5000 and a CD50) and try to use a MCL82 link room with that.

Just did a wire up of a MCL82 box with IR tranceiver and the MCL-Beolab kit.

I set the jumper in the MCL-Beolab kit to 8V as the other option of 5V did not give enough power to the MCL82, so also the role of the MCL-Beolab kit is to power the MCL network. As I only have a Terminal 5000 remote i set the switches in the MCL82 to Beomaster 5000

So what I can do is to activate the speaker relay in the MCL82 box with the speaker button on the tranceiver so the relay part is working. With the remote all buttons except mut seems to active the relay to active, and the mute button will turn the relay to inactive.

On the MCL-Beolab Kit I can measure that the data signal from the MCL82 is dropping in voltage when a button is pressed, and also on the pins for the IR diode I can see a little drop in voltage when a button is pressed, so it is probably working.

I wonder why all button presses except mute makes the speaker realy go active but of course the terminal 5000 remote was not intended for use with the Beolab MCL kit, so with the right data connection to a Beomaster 5000 it might react different.

I do not have anymore ideas for testing it right now as I do not have any of the other remote types and/or music systems for this to work with. I still have it wired up so can try to test something if you have any ideas

I hope that I’m not hijacking your thread. If so, I’ll “cease and desist” and maybe start a new thread.

Very ok, and also very relevant to the subject 🙂

Glitch wrote:

My (likely incomplete) understanding is that it just supports a subset of the remote commands that are relayed via a IR->wired->IR chain

Yes something like that as the BM 6000 and 8000 does not have any data communication for link rooms, so the MCL-Beolab Kit with an IR sender is needed to activate and make control commands to the Beomaster.

The documentation that I’ve found isn’t exactly clear and concise. I’ve found this old thread, https://archivedforum2.beoworld.org/forums/p/14327/126573.aspx which answers some questions.

I have also looked into that thread and there seems to be some confusion which I can understand as the document about the code converter not is 100% clear in relation to product names and numbers.

Glitch wrote:

It looks like the port for the “IR eye” is a simple 3.5mm jack. If so, do you think that a generic IR emitter would work? It seems possible if all it needs to do is pass IR commands into the BM8000.

I think it is actually a 2.5mm jack and probably only with two pins (I will look further into that). I do no have that much knowledge about IR emitters, if they have to be for a certain frequency. The Code converter manual mentions a cable with mini plug and a blue LED.

Glitch wrote:

Could the box be the “code converter” mentioned in the old thread?

Pretty sure it is not. The code converter do have more connectors. Having looked deeply into the code converter manual I am almost sure the box I have is the MCL-Beolab kit.

To my best of understanding this is how it works:

The Code converter can make it possible to use a Beolink 1000 to control the mentioned systems. If used with a BM6000/8000 a IR emitter has to be connected to the code converter to get the control signals to them. This can be done with or without a MCL30/82 link system

The MCL Beolab Kit is used to get data control signals from MCL82 or MCL30 link rooms into a BM8000 or BM6000 as none of them have the MCL data connection.

The Code converter ad the MCL Beolab kit can be used in parralel as I read, and that is what is shown on a drawing in the code converter manual. This way the main room can be controlled with a Beolink 1000 and the link rooms will still use the relevant remote intended for the Beomaster.

I have tried to isolate the code converter part and the MCL Beolab kit part here with the code converter in the red box. The green line indicates a connection to MCL rooms when the code converter is not used.

Hope this makes sense.

I might try to hook up a MCL82 link room unit and the MCL-Beolab kit with a LED connected to see if remote commands are passed through to the LED.

Anyway, here is a picture of the circuit board in the off chance that it is useful to you.

Thanks for sharing and intersting to see at least three variations of components for what i eessntialy the same product. But they might have been produced over a certain period to be able to let the customers expand their link system.

Is this useful for hooking up to anything other than the equipment listed on the diagram?

Acording to this page https://beoworld.org/master-control-link-mcl30-mcl82/ it can also be used with a Beomaster 8000, but aperently some modification of the link boxes are needed and also the MCL-Beolab kit type 1006. So not that versatile as the newer Beolink 1000 compatible MCL and ML link systems.

The 6-pin DIN matches the connection for the Beomaster 7000 external IR sensor

That was also my thought, and apperently it was also used for the external IR sensor for the code converter for MCL82 and MCL30.

but I can’t recall any B&O applications for the 5-pin 270 degree DIN (wikipedia shows DIN 45327, or domino/dice arrangement)

Me neither. Some searching on the DIN 45327 it seems like it has been used for stereo headphones on some audio equipment.

There is a little info in this older thread, but it does not seems to be conclusive https://archivedforum2.beoworld.org/forums/t/8365.aspx . There is mentioning of the A.aux command, but since you can not activate your BS4 with it it must have some difference in the remote codes

2 more boxes without markings that are probably also MCL82 units although on the inside the components are different than on the unit above:

Just to clarify this I have taken a photo of the inside of the box that are marked MCL82 (left) and one with no markings on it (right)

There are many similarities, but the PCB has some changes to the layout and some component are newer. I seems like the one on the left also has a footprint for the large relay that is on the other one though.

 

And just while I was at it I also took a photo of the inside of one of the MCL30 boxes. Looks even newer component wise than the 2 MCL82 boxes:

Are you sure that the BS2000/Century does not provide an AUX output in the same way as the BS4000? The service manual is a bit confusing, because the connections summary (page 1-2) shows NC (no connection) for aux output pins 1 and 4, whereas if you look at the circuit diagram (page 2-19) it shows pins 1 and 4 connected as an AUX output. Worth testing.

I think it was established in this thread that the AUX output text is a mistake in the diagram https://forum.beoworld.org/forums/topic/beosound-1-cd-version-data-link/#post-51699 so can probably not be used.

I do not want to work with a separate app just to control this product. Does it have any advantages to just connecting an essence or a core to your product? thats what I did with my 9000 and it works great.

Hard to tell if has advantages before the product is fully developed and being used.

I think the idea from the developers is to keep ML products alive with streaming possibilities more than being used together with NL products

It has been a little quiet since the Kickstarter for the ML streamer did complete.

However for those who are not on the Beotalk Dsicord channel there was an update just before new year from Poly Vection (the company who produce the electronics and make the software).

I take the liberty to insert parts of it here for info:

You will not be able to turn on the 5’s this way! A quote from Steve in another related post (there are several, if you search here): “Unfortunately with Beolab 5 it is not possible to activate the speakers via a voltage trigger – a coded Datalink signal is needed (either via the Powerlink socket or IR remote control) in order to wake the speakers before use.” MM

Ok I did not know that. Then the Almando Multiplay is less interesting as the Beolab 5’s then has to  be activated with a remote for it to work

You could look into something like the Almando Multiplay Stereo that can automatically switch between sources and also has built in Bluetooth connection https://almando.com/Multiplay-Stereo-III-Type-1-DIN-DIN-DIN-black

It also has extra inputs so you could still connect your BS3200 if you want

I have not tried this product myself, but I have a ~10 year old Powerlink switch from them that works without issues in daily use

I have given my Beolabs 6000 serial number 140….. a Maintenance service, sound was ‘good’ . When removing the speaker cloth, nothing seemed to be wrong, but as soon as you touched the woofer rubber suspension, it completely crumbled. totally perished. Then I removed the woofers speakers to look at the condition of the internal damping material, but not only after that, also at the air density of the seal of the speakers between themselves and at the aluminum housing. ( Previously I renovated a Beolab 8000 whose damping and sealing material was completely decayed. what a sticky thing. PCB was affected there.) With the BeoLab 6000, the quality of the damping material was equivalent, so completely perished. Only with the Beolab 6000 is the damping material partially glued to the housing, so it cannot sink towards the PCB as with the Beolab 8000. But still, small pieces had ended up on the circuit board and connectors, which could have caused damage in the long run. Also, damping material completely removed, including the mutual sealing edges and completely renewed. Because the rubber suspension of the speakers was also completely broken, these speakers also replaced (you can only replace the defective rubber suspension instead of renewing, but I have opted for total replacement.) For the coming years, the quality feeling and the sound, especially the midrange and the bass are sublime again.

Thanks for the info. I might have a look inside one of mine to see how the damping materiel looks, and if the woofer rubber supension is bad

Another thought that came to mind.  You do mention that you have a NL/ML converter. If you get an extra one you can make 2 ML networks connected via. NL. that way you can decide which sources that should be available through the converters.

Yes that is correct it worked fine with the Beocenter 2 I could just pause the n musik and the pc Sound would go through to my ml system but with bm/bs5 it won’t work

Ok so If I understand correctly you did not have the BM5/BS5 previously?

I am also unsure what you mean by ML passive converter? I this the Beolink Passive? If so what is that used for in the current setup?

 

Problem is that the Beolab 2000 speakers rely on a Masterlink source. There can only be one of each Masterlink source in a Masterlink system, so you can not have N.music and N.Radio from both the BM5/BS5 and the Beolink PC2.

One thing you can do is to make a separate ML network with only the Beolink PC2 and the Beolab 2000 speakers. That way you can not get the sound from the main room.

Another option would be to replace the Beolab 2000 speakers with other active speakers connected directly to the Beolink PC2. The Beolink PC2 should be setup as a Link room (option 6). That way you can both get sources from the main room and play the PC sound in the Bedroom. This however also require that the PC has to be on to be able to play the music from the main room.

Is it possible to make a setting to get notifications when a post has been edited?

I have seen more than one case where I come back to a thread and see that new information is added in an existing post, but I only see it because a new post was made or because I went back to look for some info.

I know it’s not a thing for all, and could also be irritating if the edit is just spelling mistakes etc. But would be nice to know if it is possible?

I didn’t think the Penta displays would ever work through an MCL2AV. We’re having work done in the house so my Beocenter 8500 is in storage, but when I get it back, I’ll have to test that!

Thanks for the update. I will update the first post accordingly
