This does sound weird. according to the user manual this should only happen when you do a long press:  

Hi Madskp, Thanks for the input. Yes odd indeed. I have now tried (I think) all permutations of turning things on in different orders, and with and without the existing MCL (BL3500) connections to the BM6500 in place, and still no change. I do have another IR eye and have tried that too, no change. Oddly the standby light on one of the IR eyes does not light up, but it doesn't seem to make any difference. Learning from The Princess Bride, I thought it might be helpful to list my relevant assets: Beosystem 6500 Beomaster 3300, currently in the shed Beolab 3500, currently wired in via MCL to the BM6500 Beolab 2000, currently doing nothing Beolink Active 1636 + IR eye, currently doing nothing Beolink Passive (no idea which version) + IR eye, currently connected via ML+Beolink Converter to the BM6500 MCL2AV, currently not connected MCL2A, currently not connected Beolink Converter 1611 Various original and home-made ML cables including an RJ45 distribution panel Beolab 4000 Mk1s, currently Powerlinked to the BM6500 Beolab 3000s, currently acting as Beovox 3000s and connected to the Passive. Various passive speakers (inc C75, BV3800)   I've tried the current setup both with my home-made cables and some 'genuine' ML cables with and without junction boxes, and same behaviour. I've also tried with and without a fully-wired powerlink cable between the BM6500 and 1611, which doesn't seem to make any difference at all. Currently running it without. 1611 is connected to the Aux port on the BM6500, it doesn't seem to work at all in Tape which would have been my preference. Things I intend to try this weekend:

1. try the Active at the same time as the Passive, possibly with the BL2000 too, all connected through my RJ45 distributor. If I have sufficient bits of cable.
2. get the BM33oo out of the shed and try that connected to the 1611. Not sure if this will work but if it does with the same behaviour it would suggest it's my 1611 that's the problem
3. maybe try with the BL3500 via ML, though this might be more destruction than I have time and space for.
4. I might also try the MCL2A or 2AV with their own rectangular IR eye connected on the far side of the Passive, and see how that works. But that might be a step too far.

Any other great ideas? Writing this all down has been quite helpful in itself.

The BM3300 does not have datalink86, so is not able to work with the 1611. Also if the Beolab 2000 works fine in the setup the 1611 should be OK.

Maybe just try to disconnect the MCL part of the system (remember to turn it all of before you do so), just to rule out if that has any effect on it. MCL shares the same datalink bus as the datalink 86 in the AUX conecetor of the BM6500, so there is a possibility that something could disturb each other   Let us know how your testing goes. Maybe that can make for new inputs to the mystery

Well I'd already extracted the BM3300 from the shed by the time I read your sensible comments about Datalink 86 @Madskp, so thought I'd try it anyway. Of course it doesn't have an Aux port, just CD, Tape and Phono. I connected a 7-pin from the 1611 to the Tape socket and fired up the radio, then turned on the Passive, and there was sound! I could control the volume on the Passive with the IR eye or Beolink 1000, but could not control the BM3300 through the IR eye which confirms your Datalink thoughts. Interesting, but I'm not sure whether there's much practical application for this. You could establish a link room with 'join' and volume control only I guess. Perhaps running a pair of active powerlink speakers from the BM3300 rather than Beovoxes, but still a bit of a faff. Experiments currently underway with the Active/Passive/BL2000. Results so far are consistent, but confusing! Will report back later. Dave

To explain your observations about the 1611 it csn work as a stand alone audio and video masterthus allowing for two selectable sources on any ML link room product. This was tested very throughly in another thread which among other things resulted in this great sketch made by Matador https://beoworld.org/wp-content/uploads/beoworld_images/24903/fpsantcr1nreqhki1h7n4w2zt2x2471h.jpg" target="_blank">https://beoworld.org/wp-content/uploads/beoworld_images/24903/fpsantcr1nreqhki1h7n4w2zt2x2471h.jpg">https://beoworld.org/wp-content/uploads/beoworld_images/24903/fpsantcr1nreqhki1h7n4w2zt2x2471h.jpg  

I have been working my way through that thread, there's lots of good info in there. I'd not really appreciated you could get an output from e.g. the Tape socket on a Beomaster, though I realise now that's exactly what the Audio Aux Link into a 1611 is all about. There's a world of non-wife-friendly possibilities with this stuff!

Results of today's experiments! Firstly I was wrong before about the Beolab 2000 working differently to the Beolink Passive. It doesn't, the results are exactly the same. I've got a long sheet of permutations and results, but they all correlate so far into two scenarios. Setup is: BM6500 Aux socket > 7-pin 'Audio Aux Link' cable > Beolink 1611 converter > Masterlink to RJ45 distribution board* > BL Active/BL Passive/BL2000/BL3500 Results are: Any one of BL Active/BL Passive/BL2000/BL3500 connected: Pressing the standby button directly or via Beo 4 / Beolink 1000 on the link product turns the whole system into standby Any two of BL Active/BL Passive/BL2000/BL3500 connected: If both link products are On, turning either of them Off (into standby) works as it should, with the Beomaster and the other link remaining On. But if the second link product is then turned Off (standby), the whole system turns off. This is the same whichever link products are connected, and whichever order they're switched on or off in. Putting the first link product into standby works as it should, putting the last link product into standby turns everything off. I don't (at the moment) have enough bits of Masterlink cable with the right ends to try more than two link products at once, but I suspect the same result: last one into standby turns everything off. As reported above the same behaviour appears with one product and genuine Masterlink cables so I don't think it's my home-made RJ45s at fault. So I still don't know if it's my 1611 or my Beomaster that's at fault, or something else. I have a bid on another 1611 on eBay as that's the cheaper experimental option! Would like to try with a different AAL- or Masterlink-enabled Beomaster but I don't have such a thing. At the moment.

• quite pleased with the RJ45 distributor, a few £ from eBay and easy to attach a Masterlink cable to. All shielded/ grounded too.

 

Just some extra notes to be clear: Do you start the music from the main system or from one of the link rooms, and do you also have the speakers in the main room in use in these scenarios? I belive if the music is started from a link room the behaviour is correct as long as the main room is not in play. I will see if I can verify this on one of my systems today.

So I just did some testing with some of my equipment: Beocenter 9300 - 7 pin datalink cable -  1611 - masterlink cable - Beolab 3500 MK1 both with, and without a powerlink cable between the BC9300 and the 1611. Beosound Ouverture - Masterlink cable - Beolab 3500 MK1 In bot cases I get the same behaviour as you describe even when I start the music from the master system. Now what I expected. I will see if I have time to look more into this today
