I've hooked my new ML Dynamo subwoofer via the LFE (RCA) to the LFE output (RCA) of my Sony STR-DE475 5.1 receiver.
When I turn off my Sony amp the Dynamo makes a moderately loud humming noise (as if a person were to hum loudly) so I immediately have to flip the power switch off because it freaks me out.
Why does it do this? Is this normal?
I don't think it's related to the power management function because it happens in all three positions (standby, auto, on).
I purchased it used on eBay--it's supposedly only a year old and allegedly in perfect condition.
