Re: MPAV 9000 with newer ML-Cable

Many thanks for your answers, Vienna. I will then open the MPAV and make a jumper between PIN 4 and PIN 12 -Which then will give me full operation between the AV 9000 and the MPAV 9000 with a newer ML-Cable.

Dennis (Loudspeaker):

So I have to cut the ML-Cable in two, and then insert a ML-Junction box between them?

Recommended if you are connecting only two components and
necessary if you want to distribute the sound to other rooms
(when connecting PIN3 and 12 is mandatory).

Dennis (Loudspeaker):

Why have Bang & Olufsen not just made a ML-Cable that is ready for use?
I'm a little confused!

History is the reason. The first draft of ML-System was for 2 independently distributed audio
sources and all 16 pins of the ML plug were connected.

EARLY AV9000s and the MPAV9000 used this 1st generation ML cable.

After a short time it was clear, that the cable was to thick / stiff for pulling through cable conduits,
and it was very expensive those days.

Therefore the 9-pin ML was introduced as an easy to install economy version.

Dennis (Loudspeaker):

Can you explain a little more about the further connection (PIN3+12)?

This "internal jumper" is part of every ML-junction box, and, as long as you are using at least one
of these ML-Junction boxes in your ML wiring, you don't have to do anything!

But, if you are NOT using ML-Junction boxes in your ML wiring - e.g. soldering all wires "colour to colour",
you'll have either to solder all white/blue and pink wires "together" or make a connection between
them.

Vienna:

Tompa is right, regarding the modification of the ML-SOCKET of your MCP AV9000.

Also a further connection is required in every ML-System between Pin 3 (white/blue) and
Pin 12 (pink) of a "normal" ML-cable
(but this is automatically done, if you use at least one ML-Junction box in your wiring)

Hi Vienna

Thanks for your answer. Can you explain a little more about the further connection (PIN3+12)? - And what do you mean with, that it is required in every ML-System?

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

Hi!

I just bought a MPAV 9000, but it doesn't work with newer ML-Cables. Another Beomember found this for me:

tompa:

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.

Ulf:

Nö,

geht auch mit den neueren ML Kabel:
Man muss "nur" im MPAV die ML Buchse PIN 4 mit PIN 6 brücken.

Ulf wünscht frohes Fest

Tompa says PIN4+12 and Ulf says PIN4+6, so I'm kind of stuck. Has anyone made this modification and can confirm which one will work?

Thanks in advance!
