Check if you have Mk1 or mk2 BLs, you can also shop the right cable if you don‘t like the DIY approach

I am using a DIY soldered 7 Pin DIY to MiniJack 

Mind the addtl PIN7 for ground for the mk1, so gnd is on 5+3+7

[Klaus Stoetzel]

Rob, I am using an Arylic S10 with BL3500/LCS9000, you need the B&O remote to fire it up tho

[Klaus Stoetzel]

Unfortunately curious-dreamer is not getting any feedback yet from the seller of his BL3500 ..

I got two more BL3500 in the meantime (so four now, really) and would love to get this to work

[Klaus Stoetzel]

curious-dreamer emailed the seller asking for any modding done to the unit, now we need to wait for the feedback

[Klaus Stoetzel]

Based on your testing (thanks to both of you) I am asking Curious-dreamer to get in touch with the seller of the unit to ask what he modded and to please share it with us. Seems like 8 years ago so hopefully the guy still exists, has the same contact details and remembers what he did to the unit .. fingers crossed

[Klaus Stoetzel]

I thought from the serial numbers Guy had two mk2 units but I could be wrong

[Klaus Stoetzel]

You got me confused .. between “I can´t get it to trigger” to “sound from both speakers”

So some “untriggered” setup with working sound would be what we seek, no?

Only talking about the 5V injection for stand-alone 3500s obviously …

Powerlink would trigger on Pin4 with 5V, so seems curious-dreamer is spot-on?

Still wondering on his mk1 3500 behaving like a mk2 3500 tho

 

 

[Klaus Stoetzel]

Mads, like a year ago (in this thread) you tested some variations of +5v on Pin4 (GND to 2 and/or 7) on your mk2 but seems you looked at the powerup which did not happen, if you could redo that testing with audio applied too see if it will get us some music finally it would be great, just to confirm to curious-dreamer that we indeed tried his setup. Thx

[Klaus Stoetzel]

yes, thanks, his drawing is from the other side tho

[Klaus Stoetzel]

Yes, happy to have gotten the details and possibly getting to the bottom of it

If you could test the 5V injection on Pin4 I would very much appreciate

While I have been reviewing things over and over again this morning I found this pretty recent update fom PeterPan on 3500 connectivity, interestingly its seems that this would be a special “combined” cable for mk1 and mk2 and correspond with your findings that the L/R audio lines could be reversed, see yourself, file name says it all -> For alle Beolab 3500 .. interesting …

Curios-dreamer is asking me to try his cable or point him to some post where the standard Powerlink 5v injection on pin4 was tested to not work, I am sure this is somewhere on this or the older forum, anyone can help me out please?

[Klaus Stoetzel]

Ok, just getting more details from curious-dreamer

I see… yeah, to make the display work you would probably need more tweaking. But honestly who cares, I’m interested in the music not a 90s clock 😅

I can confirm, all looks black and “off” from the front when music is playing or the soundbar is “on” and ready to play

No, my serial starts with 11 And it’s a 1993 unit running SW 1.1 according to the back sticker

 

Okay, so we have a mk1 serial with gnd on 2, no display and 5v injection working on Pin4, so yes, seems modded

I am asking curious-dreamer to see if he can get the modding details from the seller of his unit

 

[Klaus Stoetzel]

Yes, that would be my suspicion as well .. the normal powerlink power-on via Pin4 I bet got tried a thousand times 😉

[Klaus Stoetzel]

Interesting update .. here we go, let me fully quote Curious-dreamer:

pic not loading, will try tomorrow from my PC

puc shows l/r on 3/5, gnd audio+5v on 2, 5v on 4

Also, fun fact, the guy that sold me the soundbar has wired the left and right channels backwards… and I just found out now after 8 years or something. So thank you for having made check this out haha

The pinout in the drawing is the correct one though, so if you get a powerlink connector that you can solder you should be able to make your own cable. Mind that the soundbar turns on when it’s FIRST connected to the AC power and then the USB +5V is turned on (and kept on). I recommend putting a usb switch between the usb power adapter and the cable towards the soundbar

Other thing worth noting is that the display of the soundbar will not turn on, it’ll just act as a “dumb” soundbar

Hope this helps!

 

Interesting to me its a mk2 (as per the gnd on 2) and the no display / dumb soundbar comment, I would believe everybody fiddling around with the system would expect something on the display, could also be a modded unit as the usual two red LEDs should be visible all the time

[Klaus Stoetzel]

Good ! Now lets work on fixing the 5V injection as well 😉

[Klaus Stoetzel]

he promissed to get me the details of his DIN-Minijack cable and if we still can‘t get things working we‘ll get in touch with the guy things came from, lets give him a bit time and as soon as I get the information I’ll share here. From all the tests done by you and the other guys here I am not betting on any new revelations cable-wise but probably the original guy modded something and we‘ll hopefully see soon and go from there .. will keep you posted

[Klaus Stoetzel]

lol, talk about the virus, just bought another BL3500 mk1 .. (SW1.1 – with tablestand)

and I am in touch with curious-dreamer to get more details, he mentioned he bought the system from a guy who also supplied the DIN-Minijack cable to him, if we can‘t figure it out we get back to that guy to see if he modded anything

[Klaus Stoetzel]

No idea yet, still in gathering information mode

My unit is also early, so seems close enough to the 3500 mk1 sw1.1 curious-dreamer is using, thats a good start
