No problem – happy to help and good luck with the fix. I hope it resolves the problem! ?

Which one to choose?
Service manual states BC547B
And for the diode it states: 1N4148

My B&O Icons:
Not sure if I should look into that at some point.
That would make sense – those components connect to the TV/AUX AAL data (pin 6) which would explain why the rest of your datalink (between BS7000 products) is working fine.

My B&O Icons:
I checked for continity on all pins.
Maybe check for continuity between pin 1 and 6 – these are next to each other. These carry the left channel and AAL data respectively, hence if they are touching (inside the solder side of the din plug) it would possibly give some of the symptoms that you have described earlier (eg lack of data and left channel).

I know that the 7-pin datalink cable is new but perhaps it is faulty – not unheard of! Does the behaviour change if you reverse the cable?
Alternatively you could try connecting a 5 pin din between the BM7000 and BL1611, and then see if you can simply listen to the (already playing) BM7000 by selecting any audio source on the BL3500.

Sorry I meant to re-do the option settings with the whole system connected to the mains. I think sometimes messages have to be passed between products as you do the Option settings.

Sorry to ask, but was the aux cable in the BL1611’s AAL socket, not Powerlink?
Location: Warwickshire, UK
My B&O Icons:
I guess this points to a problem with my BM7000 then?
Possibly.
Have you tried powering down everything (disconnecting power), then re-connecting and re-doing the Option settings on both BM7000 and BL3500? Try BM7000 in A.OPT 1 and BL3500 in L.OPT 6.

My B&O Icons:
I tried option 6. It turns on for a second and then turns off. I wonder if there could be a fault on the BL3500.
From my testing with a BL3500, it will turn on and then off if it cannot find the source that you have selected, or if that source is simply not available on the ML network. Having said that, if you disconnect the BM7000 aux cable, the BL1611 should act as an audio or videomaster like in the diagram above, and the BL3500 should turn on with any Video or Audio selection.
Can you try a different ML cable, or test that one elsewhere?

My B&O Icons:
Hmmm I am running out of ideas!
Is the Converter definately the BL1611 version? – the BL1614 will not work.
Have you tried the BL3500 in L.OPT 6 – that’s the default and works in most setups. I am not sure if you can put the BM7000 in A.OPT 0 while you try this, unless you can temporarily move the BL3500 to another room.
If you have tested the Aux and ML cable elsewhere, you could do a test of the ML/BL3500 part of the system by setting it up as explored in this thread (page 4 onwards): https://forum.beoworld.org/forums/topic/beolab-3500-and-1611-converter-settings/page/4/
If you have the right cables, you could test in accordance with matador’s excellent diagram:

My B&O Icons:
Okay, have you checked if ML is switched on in the BL3500?
Press MENU MENU 0 9 GO then use the up/down arrows to make sure ML-ON is selected. Once selected, power down the BL3500 and remove the mains for a few seconds then re-connect.
(If your BL3500 is an early SW version, you may only need to press MENU once).
If that doesn’t work, check the serial number of your BL3500? If it’s lower than 10552474 then pins 4 and 12 must be short circuited in the ML socket of the BL3500.)

ok so the conclusion on the 1615 based on your tests must be that it will only work with a Beovision with datalink I guess.
Yes I suppose that both the BL1615’s AAL socket and the MCL2AV’s AUX/TV socket are expecting to communicate directly with a TV, hence cannot pass commands to each other.
It’s a shame that the stand-alone BL1615 can’t be used to extract the audio from masterlink. Looking at the circuit diagram, there seems to be a couple of points where the ML ON/OFF could be by-passed, but I think that the TV would still need some sort of data command to turn its ML output on (even when the TV is already turned on).

My B&O Icons:
which commands did you use? With the 1611+MCL2AV combination it was the AV+Video source command or shift+radio+1 that made the sound from the tv come to the MCL2AV
I was mostly trying AV-TV*, but have just tried shift-radio-1 and that doesn’t work either, even if the TV is already on. AV-TV does turn the MCL2AV on (the sensor LED goes out) but the TV does not react either from standby or when already on.
*EDIT: I tried all other audio/video commands also!

My B&O Icons:
So I just tried adding the MCL2AV (and IR sensor) and it didn’t work – I tried several option settings on both TV and MCL2AV. But looking at the MCL2AV circuit diagram, pins 1 and 4 are only an output hence effectively I have two audio outputs connected, which cannot work.
TV source for this and earlier test was the TV’s internal tuner (which worked over ML before with the BL3500).
Regardless of the lack of audio, the BL1615/MCL2AV setup will not even pass control commands to the TV to turn it on etc. So this looks like a non-option!

I just tested a BL1615 connected to BV10-32 with ML – unfortunately there is no line output from the AAL. I checked AAL pins 1 & 4, and then 3 & 5 (the latter just in case the service manual was wrong).
So it looks like some form of AAL trigger is required. When I get a chance I will see if the MCL2AV (with IR sensor) can provide this.
EDIT: I suppose that the TV needs to receive some form of trigger in order to activate audio over the ML, but it needs to receive this via AAL -> 1615 converter -> ML data.

@Guy: did you have a 1615? then maybe it can be tested with your Beovision or your beoport if you are up for it?
Yes I will give this a try with my TV later today, basically just to test if the active ML source is passed through to the BL1615’s AAL socket.
(I suppose we could also investigate connecting the BL1615 to the MCL2AV’s TV/AUX socket to see if control is possible, but this may have to wait a few days and my MCL2AVs are packed away again at the moment!)

It would be great to see the setup that madskp has explained up and running, so hopefully you can get hold of a BL1611 and MCL2AV and give it a try!
Here’s a thread that confirms that the MCL2AV will control a Beogram using CD source-selection: https://archivedforum2.beoworld.org/forums/p/44963/325703.aspx
Unfortunately Gregg never answered whether PHONO would work but I doubt it. Also, in that linked thread the Beogram was a ‘local source’ but I would hope that the BL1611 would make if available across the whole system.

Ok, new belts fitted, and, it works, well, there’s a minor victory!!!
Great news – I think I know the YouTube video that you followed and agree about the longwinded-ness! ?

Try clicking the link, then go to the browser’s address bar and manually add ‘archived’ before the word ‘forum’, and ‘2’ after.
Not ideal but it works!
