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

To be honest there are a number of other variables - all of which make thorough testing very difficult:
  • Mk1 or Mk2 BL3500
  • SW level of the BL3500
  • Whether ML is turned ON or OFF on the BL3500 (I can't think of anything else adjustable in BL3500 menu)
  • Whether the timer is set to 'ON' on the BL3500
  • What audiomaster is being used, and SW level (does it send PL trigger on pin 4?)
  • Whether the PL cable is fully wired (mine is)
  • Whether the BL3500 is fully working
  • Whether the BL3500 has been modified
I did try lots of option settings, also tried ML ON and OFF, and with BL3500 timer both ON and OFF.

I thought from the serial numbers Guy had two mk2 units but I could be wrong
I have done some testing now with  fully wired powerlink cable from BS Ouverture to BL3500. ML turned off in all instances. MK1 SW 1.0: Speaker is not triggered when I play music on the BS Ouverture, but the BL3500 can join in with a press on the mute button or a source button on the remote. So same as Guy registred in his test. MK1 SW1.2: No test. I had forgot that it was dead for some reason MK1 SW 2.0  Same behaviour as SW 1.0, but the speaker died in the proces. MK2 SW 3.1 Will not active at all. This corosponds fine with my testing with the wireless W1 where only the combination of the special data signal from the W1 and the trigger signal on pin 4 would activate it. A note on the MK1: I don't think it would make sense for the trigger signal on pin 4 to with pin 2 as ground to do anything on a MK1 since pin2 is not connected and pin4 is a signal path for sound
When I listen closely I can hear a high pitched whine from the right hand speaker – sounds like a grounding problem so something is not quite right.  Maybe polarity reversed on that channel – does that make any sense?
Both reversed polarity of the sound signal, but also you are putting 5V trigger on pin 4 and 5-12V on pin 1 which are both part of the sound signal path. Also you only have the data shield as ground since pin 2 is not connected in the BL3500.

Yes that makes sense - thanks fo explaining.
