It might be.

The 1610 kit is for use with other audio than the MPAV9000. If the ML cable is special witch this thread proves it is then its the solution to the problem.

Maybe a contact to seller for a upclose picture of the ML cabel should be done?

I had the same problem connecting an Ouverture to a AV9000. A normal ML cable will not work. You need to short circuit some cables in the ML. After that I had no problems at all.

Will contact my dealer in order to know exactly what needs to be done. Can't remember at this point.

Hi,

You can use the normal masterlink cable but you have to make a short circuit between pin 4 (ML sense)and 12 on masterlink socket in MP AV9000 stereo

that have bin done in struer from serial number 10822537.

Thank you so much for everybodys input on this it is greatly appreciated! I have contacted Ulf who gave me perfect instructions on where to solder with images and this has now been done so now I just need to take the Hi-Fi back to the customer and hope that it works!!
