Then it could be the powerlink cables that arent sheilded enough.

Their complete setup is the following: Beomaster, Beogram, Beogram CD 4500 connected to BeoLab 8000 (Main speakers)&nbsp;and Beovox CX100, RedLines through MCL.</p><p>The hiss or buzz comes in various intervals and last under a second. It can be head from all the speakers, so I suspect the Beomaster to have some sort of short circuit.</p><p>Do any of you have a possible explanation, or better a possible&nbsp;solution?</p><p>Best regards</p><p>Christian (on behalf of my dad...)</p><div style="clear:both;"></div>
