The speakers are installed by my B&amp;O dealer, so I was presuming they knew what gear to use. Maybe I will have to review that opinion...&nbsp; <img src="http://forum.beoworld.org/emoticons/35.gif" alt="Hmm" /></p> <p>I will post later when I have checked!</p> <p>/Anniber</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/252142.aspxWed, 13 Jan 2010 07:29:00 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:252142Puncher0https://archivedforum.beoworld.org:443/forums/thread/252142.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=13&PostID=252142<p>What leads are you using to connect your BL3s?

Have over time noticed a clear and very annoying humming in the link speakers - clearly&nbsp;AC 50Hz coming through. I have tried everything (except the right thing, obviously): Turned off all possible electronic equipment near the speakers - still humming. Exchanged the ML box - still humming. Had the electrician there to check the Lex Com Home system - slight reduction but still humming. Connected BL3 direct to source - still humming. Swithed positions with my BL4 - still humming in the BL3 (!). Brought the BL3 speakers to my dealer and hooked them up - NO HUMMING. Only thing I have not yet tried is exchanging the power module in the Lex Com Home system.</p> <p>Does anyone have aclue on what I should try next - I am completely at a loss...<img src="http://forum.beoworld.org/emoticons/37.gif" alt="Confused" /></p> <p>Looking back, I should have turned to you guys in the first place - I always knew the true B&amp;O experts reside here!</p> <p>Thanks in advance,</p> <p>Anniber</p><div style="clear:both;"></div>
