I had chalked it up to perhaps thermal expansion of the heat sinks rubbing against the plastic case, but in truth the amplifiers probably need servicing.<p> The displays are more curious, especially since both failed at once. Assuming you're not daisy-chaining, try switching the two SpeakerLink cables at the back of the 9500? (so that left and right are temporarily reversed.) Ridax is the real expert on these displays.<div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/43357.aspxMon, 03 Sep 2007 14:38:05 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:43357stewartep0https://archivedforum.beoworld.org:443/forums/thread/43357.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=43357It is only the one.<div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/43112.aspxSun, 02 Sep 2007 15:37:54 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:43112stewartep0https://archivedforum.beoworld.org:443/forums/thread/43112.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=43112<p>I need to check but I think its only the one that makes the popping/hissing noise.</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/43106.aspxSun, 02 Sep 2007 15:14:45 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:43106Die_Bogener0https://archivedforum.beoworld.org:443/forums/thread/43106.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=43106<p>And both of them show this effect?</p><p>Have you used 2 cables or a chain (BC-Penta-Penta)?</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/43099.aspxSun, 02 Sep 2007 14:48:31 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:43099stewartep0https://archivedforum.beoworld.org:443/forums/thread/43099.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=43099BC9500.
