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?  

they are the rectangular ones  

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

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

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

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: Login to view image

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?  

Thank you so much. I will try this tomorow
