This is adjusted by a trimmer potentiometer. If the trimmer pot is oxidized or otherwise flaky, it must be replaced - I understand Martin Dillen has a good supply of them.</p> <p>It&#39;s a good idea to replace the trimmers for each channel, while you&#39;re at it.</p> <p>And while adjusting them, speakers must NOT be connected, and the volume control must be fully &quot;Low&quot;.</p> <p>Menahem</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/210335.aspxSun, 14 Jun 2009 07:37:27 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:210335Friedmett0https://archivedforum.beoworld.org:443/forums/thread/210335.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=210335<p>I have a palisander Beomaster 6000 &#39;80s that does the same allthough at&nbsp;lower volume.</p> <p>It is a heating issue of some sort I think&nbsp;and the Beomaster is shut down for safety reasons.</p> <p>Try unplugging the speakers and see if it takes the load on 32.&nbsp; </p> <p>Mine does and it means that the speaker outputs needs to be adjusted as they are out of specs.</p> <p>That is what I have come up with.

My 5500 has the problem that it is getting/running very <i>very </i>hot, but it doesn&#39;t affect the sound quality and/or shuts down. I&#39;m afraid you have to try taking it to a B&amp;O Tech <img src="http://forum.beoworld.org/emoticons/06.gif" alt="Sad" /></p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/207915.aspxTue, 02 Jun 2009 18:42:47 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:207915two40https://archivedforum.beoworld.org:443/forums/thread/207915.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=207915<p>Well it might not be over heating. but whenever i listen to my beomaster at a louader volume it shuts off by it self and i have to reastart it. IM guessing is something thats not working correctly and it turns it self of before something worse&nbsp;happened. So it shuts it self of at volume 32 everytime, sometime it takes a little bit and sometimes it just shuts off at the moment it hits 32... anyone have any ideas what this can be? a fuse that is broken?&nbsp;</p> <p>&nbsp;</p> <p><b>summarize</b>: beomaster 5500 turns off at volume 32 by its self?</p> <p>&nbsp;</p> <p>thank you for your time.</p> <p>&nbsp;</p><div style="clear:both;"></div>
