      Hi

      I have a problem with Y-connector.

      Beolab 8000 speakers are connected to Bv9 and I have been using

      Y-connector to connect beolabs to Beosound 9000.

      But……

      When I plug cables from Beosound 9000 to Y-connectors sound coming from

      Beolab 8000 speakers cuts significantly lower level. About to half.

      This happens even when 9000 is not powered on.

      Hmmm……….

        Yup.  Don’t do that.  Splitter cables are intended to have one driving device (BV *or* BS9000) and two speakers.  A switch box — common manufacturers are Almando and OneRemote.dk — will use either the presence of the Powerlink “Power” pin or the audio signal to switch your speakers back and forth.  (There is a technical answer that I just don’t remember about how line output impedance of the source and RCA line input impedance of the speaker[‘s built-in amplifier] are supposed to relate, and what happens if you put another source on that Y in parallel with the speaker, thus the original source “sees” the wrong  impedance, not just a speaker or two.)

        P.S.  Don’t throw away that splitter cable — you’ll need it because the Powerlink switch boxes only have a single DIN-8 jack output!

        P.P.S.  The true B&O-heads here will tell you that you ought to be running a MasterLink cable between those two sources, for an integrated setup.  One remote, speakers connected to one device, automated source switching thru it, routing the IR remote commands — totally B&O-whole-house-cool!  But the switch boxes work with *any* two sources and don’t require learning anything about B&O systems’ “Option” settings.  Given that you started with a simple Y cable, I suggested the easier-to-understand method.  But it is sub-optimal if you could get MasterLink configured instead: both your BS9000 and BV9 support it!

          That impedance came to my mind but I didn’t “believe” it because level

          went down even when BS9000 was not powered on at all.

          Have to go through boxes if I can find an ML cable. If not might buy one of those boxes you suggested.

          Thanks!

            Having boxes of B&O cables means you have done this before; good!  But if your boxes leave you empty-handed, as a done-this-before oldster, you might not be familiar with the modern method of connecting MasterLink: buy a pair of cheap ML male –>RJ45 female adapters and run an Ethernet cable between them (preferably shielded) — much easier to find custom lengths than buying a genuine ML cable.  Cheaper than the PowerLink auto-switch boxes, too!

              Thanks for advice. Found ML cable from local dealer;)
