I picked up a buzz on my speakers. Sometimes louder than others. I eventually traced it to the downlights - any idea what would cause it?
1. The lights are on a different circuit
2. The downlights are LED (non-dimmable) - on 2x dimmable 2 way switch. (we don't dim them).
3. There is a good possibility that the cabling in the roof for the lights cross the cabling for the switch circuit the receiver is on. (the roof is a nightmare to work in (flat roof))
As soon as you switch the lights off, the buzz is gone.
The processor is a Marantz AV7005 connected to a Rotel 1095 with balanced cables.
I'm assuming power conditioning might resolve the issue? Is there any "cheap" way of doing it?
75% of the time the room is used for movies - with lights off - its the 25% that bugs me when I'm listening to music
