A hum you’ve got? When I installed my LUMIN s1, I heard a Chinese radio station. (I’m in Canada, so it could have been a local station.) I contacted the Asian distributor, and they were totally perplexed. Meanwhile the radio signal got louder and louder, first through the right channel, then through the both. Got louder and louder.till it almost drowned out the music I was playing through my system. No fun at all.
My amps are a pair of coincident technology monoblocks. Cables are all shielded. Never happened to my system before, through all its 30 years of configurations.
Solution I found was to add a passive pre to my system. Like, the one I kept stored in the basement and hadn’t used in 15 years. Actually forgot I still had it. Specifically, it was a Placete RVC. Plugged that in and shut off the volume control function on the LUMIN. And went back to using the placete for volume control. That solved everything, don’t know why, I’m not technically minded,but it did.
