    This might be me being stupid but I can’t for the life of me get a reaction from the Beosound 9000 using the Beo4.

    What I tried:

    1, I have bought a dummy-plug from sounds heavenly. I can’t really tell the sockets apart so I’ve tried it in two of the three (the speaker cable is in the third).

    EDIT: I got the sockets sorted via the reseller of the dummy-plug.

    2, I have tried to switch mode on A.OPT and tried on a few different ones without success.

    3, I’ve checked the batteries

    The remote seems to work, it is responsive I can add and remove buttons from the list for example.

    A few possible problems that might be the cause I can think of.

    1, Do I need to unplug the mains for the beosound 9000 to start in a different mode?

    EDIT: Wrote this at work so I couldn’t try but did when I got home and it didn’t make any difference…

    2, I read somewhere that the caps on IR-sensor start leaking over time. I’m used to soldering so replacing a few caps shouldn’t be a problem. But it’s a big project to get the board out for it not to be the problem. Do you think this might be a reason?

    3, It might be the remotes IR-sensor in which case I’m lost. I haven’t found anything relevant as to fix that sensor.

    Any help would be much appreciated!

    We might need a few more answers fisrt.

    1. Does the system work using the onboard controls? (most important detail)
    2. Initially the only button it will react to on the remote, is when you press CD to turn it on.
    3. Have you tried looking through a phone camera to see if the remote is sending out IR. Press CD on the remote and you should see the two IR emmitters on the remote glow/flash (I’m told that if using an iPhone look through the selfie cam).
    4. What speakers do you have connected? I assume they are not B&O Beolab Speakers. You only need the Dummy Plug if NOT using Beolab Speakers. There are two powerlink sockets (as marked). The third socket you see is an AUX input.
    5. BS 9000 sockets
    6. If you have non B&O speakers connected, how is that being achieved with your speakers? The BS9000 cannot power non B&O speakers so do you have a separate Amp connected?
    7. Option Programming may be what the issue is. You need the system in standby when you set the options. I believe that it should be set as A-OPT 1 if you are using the dummy plug.
    8. You are correct that people have had issues with the IR eye failing. Ther are a few posts on the Archive Forum 2012-2022 if you do a search there.

    Hopefully your answers will assist us to help you. Good luck
