When i tested the installation and the options in the connected rooms, i also had to separate the bm4500 from the mains a&nbsp;lot of times. I also experienced this clunking noise so i think it is normal with these units (not designed to separate all the time). What you can do is to diconnect the speakers before you reconnect. </p> <p>I also appreciate the bm4500 for his optical and sound quality.</p> <p>Best regards</p> <p>David</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/329216.aspxFri, 24 Jun 2011 09:27:12 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:329216Kokomo0https://archivedforum.beoworld.org:443/forums/thread/329216.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=13&PostID=329216<p>I have a Beomaster 4500 and if I have to umplug from the mains for any reason, I really dread having to plug it back in as this always results in a brief but quite loud electronic &#39;clunk&#39; through the speakers. It&#39;s always been like that and doesn&#39;t seem to have any adverse effect but I just wonder if this is normal. Does anyone else with one of these units experience this?</p> <p>Finally, is it OK or should I be concerned (after all these years!).</p> <p>Thanks.&nbsp; </p><div style="clear:both;"></div>
