So cable-wise there is some hope but remote-wise it’s a different story? The fact that there’s no online evidence of someone who’s been able to pull this off on an old unit like this, seems like a bad sign.

Right. Of course there might be somewhere inside the control center were it can be switched on, but that would require both the service manual an some understanding of the circuits to figure out I guess.

With a cable to the other Penta, and that one connected to the other one, they suddenly work

Do the displays also work or is it only sound from them? If no display then It could very well be a fault on the datalink circuit on the Beomaster 7000. There is a transistor and a diode that can fail.

I am beginning to suspect theat there is something wrong with the Masterlink; according to your drawing, the powerlink is not used at all here, so I pulled that out when I needed the second plug in the Penta to connect to the other Penta. Since then, no sound at all from the BV7. And I have nowhere to connect it.

Remember my drawing is just how I imanginge that your setup is/was connected based on what I can read in your post’s to better understand your problem. As I have not seen your connections I can have misinterpeted some information, so the drawing is best guess based on how things usually are connected  Therefor the best would be for you to try to verify if the drawing resemble how your system was connected before the problems arised.

About the BV7 that should be connected via Masterlink so conenction to the Black Beolink converter Box. You might have a junction somewhere on the Masterlink connection where it is split to the BL3500.

I have just been experimenting with a NL/ML Converter connected to BC2300 via BL1611.  I can start the CD and skip through tracks, but my BC2300 also starts in a muted state.

I think the reason for this behaviour is that the way the NL/ML converter connect to a B&O music system is in many ways how it would work with a connected Beovision or a Link room where it is the speakers on the controlling unit (in this case the NL/ML converter just controlled via App or another NL device instead of a remote) that is started and not the speakers connected to the the music system

Unlike you, I can then use the Beo4 remote to unmute and control the volume

Do you still use the Beolink Passive for local speaker? That may give an other result than “real” Powerlink speakers

Hi again. I just tested the setup with a Beolink converter type 1614 and that also works. A type 1612 is identical to 1611 but for the US market so that would also work.

Hope this help to narrow it down

I just tested this again with the BS5 setup as Audio master in option 2 connected to a Beolink Converter type 1611, and I can indeed get audio input from the 1611 AAL connection when I press TV or any other video command on a remote.

With these settings eventual link rooms should also work in this setup

Location: Denmark

It should be possible to get extra sources via Masterlink by the use of a Beolink Converter type 1611.

If you connect the converter via Masterlink the BS5 should be able to get the input from the AAL conector by using video commands like TV, V.MEM, DTV (it does not matter which video command is used) etc. This of course require that you do not have a B&O TV in the same room that also use these commands.

I did some testing of it int this thread https://forum.beoworld.org/forums/topic/beosound-5-a-mem/ where I also tested other possibilities.

If you need more info I can try to do a new test just to verifiy that I was not overlooking something when I did the testing in that thread.

Was a little curious about the BLC 1610 so I had to open one up to see what is ticking inside: All pins in use on the two ML connectors are wired in parallel, so just kind of an internal junction box. What is unusual with the ML connectors is that pin 3, 4, 5, 6 and 12 is all connected where pin 12 is supply voltage +, and most of the others are normally no used. This however explains where this box is getting power as the same pins are supplying +12V on the diagram for the AV9000 One other curiosity is that next to the external 1-2-3 switch is an internal switch with 2 positions: These are named:

• Central 1610
• Local 1611

Not really sure if that means it will function like a 1611 if it is in that position. Might do some more testing around that at a later point.

I found a MCL service manual on Archive.org that besides all the MCL2 stuff (also for the newer MCL2AV) also has the service documentation for the 1610 AV9000 Audio kit.

This reveals what both the internal and the external the switch do:

However a little disapointing for those settings where it is for future use.

With this knowlede I had to do a test to see if I could get it working. I have tried with my BC6-23 as Videomaster (V.opt 2) and my BC9300 as Audio system in A.Opt 0 and the 1610 with the external switch in position 3.

No result I could not get the TV to start the BC9300. Also tried to add more power from an external 12V power supply as the 1610 use som extra pins in the Masterlink connector for power, but still no result. I tried with 2 of the 1610 boxes I have with no luck.

And just to verifiy that the TV and the beocenter worked togheter I tested the connection between them with a Beolink Conveter 1614 in between and that worked flawlessly. I guess the 1610 boxes probably either only will work with the AV9000 ore are defective.

Just adding my 2 cents to this topic as I also think it would be cool to be able to repurpose this piece of art.

Looking at the service manual for the TV part of the AV9000 ( I have not seen on for the control center) I can see that the Masterlink connector for the control centre use a different pinout than the normal. For example the data +  and data – are on pin 8 and 9 instead of pin 1 and 2. They are interconnected in the TV though, so it is Masterlink data. Also the Audio part is on different pins and instead of being balanced audio in normal Masterlink it just looks like a left and right analog audio signal with a ground, so it it could be activated it should be fairly easy to supply an analog audio signal to it.

However the biggest issue is probably how to turn it on since the IR receiver is in the TV part of the AV9000, and is the probably transmitted as Masterlink data to active the control center. And since this principle has not be used for other products I have a hard time seeing what could substitute the TV part of the AV9000.

 

Speaking of AV9000 I have four AV9000 Audio kits in my collection. It is much like a Beolink Converter 1611 for connection to a audiosystem with datalink, but with two masterlink plugs and feed with power from the TV via some extra pins in the Masterlink cable. I have not been able to verify if they work since it’s a little special.

My bad with not knowing the function of them. Don’t worry I have used X2 classes of same type and brand as the ones that were in it already

A little thought from me: what role is the NL/ML converter setup to? I am not sure it can work if the converter is setup as Source center as this will make source collission on the ML part.

This will not be the case for the BC2 if it is N.music compatible.

BS Ouverture does have Datalink yes, but it is what is called Datalink 80 and is used for controlling Beogram record and CD players, and Boecord tapeplayers.

Without knowing much about theLintronic box I think that it use the Datalink 86 protocol for communication and that is not available in the Ouverture’s AUX connection as the Ouverture has Masterlink. It is however available on the Beocenter 9300 AUX socket.

One more thing that came to me

Every time after you power down the system and power thing up again start with the Beomaster, the the Beolink Converter and the the Beolab 3500. Sometimes communication between components go wrong when powerede on in other sequence

lenhi wrote:

Could it have something to do with the OPTIONS>A-OPT in Beo4?

I don’t belive that the kind of errors you are experiencing has to do with the option settings.

My money is more on a defect in one of the components in the system or in a cable.

As advised before I think you need to isolate the problem by trying piece by piece what is working and what is not

Location: Denmark

[Madskp]

This is getting complicated.

I think you might need to unplug everything from the Beomaster 7000 and then try to connect one thing for example the Pentas to confrim they work as they should. The disconnect the Penta’s and connect the Beolink converter with only the Beolab 3500 connected and so forth just to verify if each part of the system works on it’s own.

Problem is that the data signals for both Powerlink, MCL and the AUX socket on the Beomaster 7000 is connected internally, so a fail on something on one of these sockets can affect the functionality on all the other sockets.

Remember to unplug power to all components before unplugging and replugging things

lenhi wrote:

Should I get a speaker cable instead of the DIN to connect the pentas to each other?

No not sure that would work. The optimal connection for the Pentas are Powerlink.

lenhi wrote:

BTW: how does the Powerlink know which speaker is which in the main room?

There are selection switches on the speakers to choose if it is playing the left or the right channel. The Powerlink cable carries both channels

Just a few things I have noted in the last design change of the forum:

•  If you choose the view latest topics or latest posts you can only see 10 posts. Before you could go back longer. It would be great if that could be possible again as this is a good way to catch up on what has been posted since last visit on the forum.
• If you go directly into a subforum there is a colum named last post to the right where you can click and navigate to the last post in a therad which is great for long threads. This last post colum is not there if you enter via sticky post, latest posts or latest topics. It would be great if that functionality could be reestablished.

Thanks in advance

Just tried to see if setting the MCL2A to L.opt 6 did any difference, but is till responds to both normal and Link + commands. not sure if it is actuall going into option 6, but it responds with a blink like when option settings is done.

Also tried to see if V.OPT settings would do any difference, but still the same.

Ok many things going wrong it sound like, but it may be related to one single thing.

To get a better understanding of your system I have made this little sketch. SOme og the things I am unsure of is the role of the television you mention and if the Beolab Pentas are connected to that. or to the Beomaster 7000?

The black box you do mention is called a Beolink converter probably type 1611.

If my assumption of how your system is connected is somewhat correct I will suggest that you try to isolate the problem. I think we should not take the CD player and PC connection into account at first as these problems might be affected by link issues.

Before every step power off all components in the system to avoid anything breaking in the proces:

• Disconnect the the Powerlink wire between the BM7000 and the Beolink Converter. This is only nessecary for certain situation and testing what is wrong can be done without it, so better leave this disconnected. Verify if the problems persist?
• Disconenct the AAL wire between the BM7000 and the Beolink Converter do the Bedroom, Kitchen and Pentas work now?
• If not now disconnect the MCL wire and connect the AAL wire again and see if the BL3500 and the Pentas work now?

Some years ago, mice had gnawed the wires in the attic, and I had a technician from B&O over to solder that and check the system

This could of course also cause problems if there is a new problem with the wirering, but lets start with isolating the problem

Just had a thought that made me return to this thread.

What if the MCL IR eye is dependent of the MCL2A box to get an option setting. Although the data connection just passe through from the IR eye to the MCL cable, maybe there could be something with the yellow wire that goes to the speaker on/off circitry of the MCL2A box.

So I wired it up again with a 1615 where ground the data pin 6 form the AAL connector is connected to the MCL2A box data and ground screw terminal. Masterlink from the 1615 is connected to my Ouverture.

Again I can control the source on the Ouverture just fine, but wheether I set the MCL2A to option 2 or 4  i respond both to normal commands and Link + commands.

I wonder if the option settings of the MCL2A has some dependency on the connected Beomaster if used in the intended MCL configuration.

Looking at the intended purpose for the 1615 is with a Beovision TV, but option settings for that would probably be 5 or 6. Have to look more into that
