Masterlink sound problem please advice

[Andre Bolhoeve]

I have an masterlink system in my house in 6 rooms

every room has one ir and two speakers.

the main unit is now a beosound 9000

 

the problem that i have now is that is f i point the remote on one ir in one room to higher the sound, it wil go up in every room.

when i lower the sound it will go down in every room.

how can i fix this so that the sound wil go up or down in the room i am poiting the remote. The rooms atre sepperate with doors closed

 

let me know what to do

Does not sound like somthing that should be possible in a Masterlink system.

Are the IR eyes the round silver ones or the older rectangular white or black type?

 

[Andre Bolhoeve]

they are the rectangular ones

 

[Madskp]

Then what you have is a MCL (Master Control Link) system.

Someplace in your system you probably have a ML-MCL converter that act as a amplifier for all of the link rooms. As the amplifier is the same the volume in all link rooms follow each other as they probably just have a relay box (MCL2A) that activates the speakers in the rooms

There is an option to upgrade the relay box to a more advanced one called MCL2AV that has some compensation that makes it possible to have near individual volume control in the link rooms, but that will also require a separate amplifier in each room or active speakers.

If you want to upgrade it might be more feasable to convert to a Masterlink system where you can get real individual volume control.

Let me know if you need more info

[Andre Bolhoeve]

Thanks for the input.

it used to work fine. bus sinds yesterday no more.

There is a beolink passive “a big black box”

and smalles gray boxes in every room. i think the ir and speakers connect to them

let me know what you think

I appricated the help

[Madskp]

Just to be sure, doea the small grey boxes have connectors on the front or just a flat surface?

[Andre Bolhoeve]

I have made a diagram of how it is connected This is how far i could follow it.

I think most is there. i think from there it will go to the boxes in the rooms.

I hope this wil help to find the problem

In your diagram, one thing that really doesn’t make sense is that the Beolink Passive 1655 appears to have both a masterlink connection (black wire) and a powerlink connection (orange wire).  For the passive, both of these are ‘inputs’ and only one should be connected.  Also, in your diagram the orange wire seems to comes from the box below, which I assume is an MCL2E (designed to extend the MCL system).  However, the orange connection from the MCL2E would be an MCL cable, rather than powerlink.

I would try disconnecting the Powerlink connection from the Beolink Passive 1655 and see how the system behaves.

If it then works, what you would have is effectively two MCL systems, each with its own ‘independent volume control.  (The Beolink Passive 1655 would be acting as a second ML/MCL converter)

EDIT:  I have incorporated your diagram into my post to avoid having to click to open:

Hi again

Wow that is somewhat complicated, and I guess that you could have misread some connections between things, but this give a better picture of what you are dealing with.

Like Guy I also wonder what the purpose of the orange wire is, and if it is actually connected to the MCL2E in the other end?

The MCL2E is an extender that is used when there is more than 4 zones in a MCL sytem, and I wonder if it is nessecary the way your system seems to be divided with two amplifiers. But I would leave it for now so you don’t make to many changes.

Have you recently done any unplugging of cables on the 1655? Could it have been a cable that should go into the IR port instead? Like guy suggest I would also try to power down the system, remove that cable and start it up again to see how things react.

The three grey boxes shown in the lover left corner are MCL2A and so is the first box after the 1551. These are as mentioned earlier just relay boxes to activate speakers and will follow the volume of the amplifier, so I will suspect that some of your zones has had the same volume control all the time.

I will asume that some of the MCL2A boxes are connected to the red wire from the 1655.

The IR eyes connect to the MCL2A and MCL2AV boxes to control them. It is the thin grey wire going into them. So every room should have a IR eye and a grey box (MCL2A or MCL2AV).

Also I wonder what the deal is with the ML delay box? are there other Masterlink components that we do not see from these drawings?

 

[Andre Bolhoeve]

Thank you so much. I will try this tomorow

I just bougt this house. I think there was a bV 7 where I placed the 9000. And an other tv in a other room.

When i placed the 9000 i had onley sound from 5 rooms there was no linkcabel connected to the nl/mcl unit. the volume worked undepended in the 5 rooms. they  adviced me to place the splitter  and connect the link cabel also to the nl/mcl unit. It looked like it worked. but the next day the sound was going up and down at the same time in all the rooms. Even when i restored it and disconected the link cabel from the nl/mcl

I wil try to disconnect the powerlink conection tomorrow. and see what happened.

There is one thing that i noticed today. The MLC2AV makes a hhhhhssssssssss sound for about 15 secondens when powerd up then this stops. i disconected the power from the MLC2AV for now. To be save. the sound stil wil go up and down in al rooms with the MLC2AV disconected from power

Ok this explains some of the confussion with this system.

I have a feeling that this may have been connected differently years ago and then have been upgrade. Probably the Beolink passive and the ML-MCL box was not part of it to begin with (these two amplifier boxes are by the way the same, just with different naming and type numbers).

I think that will be a good start as there should not be any ring connction between the units, and the MCL system after the amplifier boxes should work independently of each other.

I would not suspect that in the first place

 

[Millemissen]

If speakers/rooms are powered from the same unit (the Passive//ML/MCL Converter), all rooms should behave equally turning up/down the volume.

You are then controlling the amp, not the speakers in the individual rooms.

Just to confirm – which speakers are in the rooms? – passive boxes I suppose!

Also this delay box makes no sense – I would skip that and go directly to the ML distribution box.

(Maybe there was not a BV7, but a later, NL-based BV in the mix?)

I seem to remember that in a MCL system, the volume is independent, to a point. I have much the same system in my house – MCL feeding both MCL – A and MCLAV devices and a NL/ML converter as well. Confess no longer use most of it as have Amazon Echo devices through the house, some feeding into B&O systems – rather more convenient!

First I waned to thank you and everyone for there thoughts and input

I have made some adjustments. as advised, i removed the dely box and disconected the powerlink conection.

I made a new diagram.

What i have now:

When i Disconect the masterlink cabel from the beolink passive. with the powerlink conection in place the 9000 wil start go to radio cd or aux with the remote on all ir but I have only sound in room 1. the sound in room 1 wil go up and down from all the rooms.

If I disconect the powerlink conection and conect the masterlink to the beolink passive. In room one the sound wil opperate seperetly from the other rooms. I think this one is conected to the NL/MCL
The other 5 room stil act the same the sound wil go up and down equelly.

I think they are connected to the beolink passive.

so only room one is now individual from the others

I think that this is the best that you can hope for with only two ‘Passives’.   Two amplifiers = two volume levels.

There are ways to separate out the rooms so that each has a discrete volume, but you would need to add either extra Passives, or Beolab (active) speakers.  As madskp has already said, a good solution would be to replace the entire system with one that is ML (rather than ML/MCL) based.  To do so, you would simply need a Passive in each room, each controlled by one of the newer round IR sensors, plus lots of ML cable (or equivalent).

You should also be able to have individual volume control in the room where the MCL2AV is placed if it has Powerlink speaker connected. If it has passive speakers connected then it is probably setup to act as a MCL2AV like the others and will follow the volume

The Speakers is the rooms are pasive.

What i do not onderstand is that it used to work.

you could adjust the sound individualy in the rooms.

 

And what does the MCL2AV actualy do?

Unless there are any hidden components that we do not see I can not figure out how that would have worked.

The MCL2AV can convert the amplified speaker level signal in the MCL system to a line level signal that can be volume regulated. This however only works for the powerlink outputs on the MCL2AV thus requirering the use of Active speakers or an amplifier between the MCL2AV and passive speakers.

If passive speakers are connected directly to its passive speaker ports it works just a the MCL2A relay box without individual volume control.

thanks so far.

can I replace the MCL2A one at a time. for a MCL2AV on the same wire with active speakers. wil that room than be individualy from the others ?
