REL Hum 60 cycle I believe


I recenyly added a rel sub to my system and used their suppied cable. Problem is if I turn off my amp I get a very loud 60 cycle hum from the rel. It seems to me something is not grounded correctly? Can anyone help?

I had the same problem with Luxman amp / Mission sub. I learned to remember to shut the sub off before the amp...other than that they both worked fine.
Thanks, I would rather not have to turn off the sub as it is in a very tight spot. I will Call Sumiko but they are all at CES!
REL sais you can leave it on. It only burns something like 4 watts when no signal is present. (See the manual).
