Title: Humming noise when changing inputs
Post by: kekoukela on July 01, 2015, 02:08:38 PM

Hi everyone. so I have a submissive that is connected to a crack and computer speakers. I rewired it so it is one input to three outputs. I'm beginning to get a low grade hum when i switch from the crack to the speakers. . . is this normal?

The ground connection may be temporarily lifted when switching, does it only hum a little when the switch is thrown, or does it continue to hum once the next position has been reached?

Sorry for the late reply. and a Happy belated 4th of July!

It's a continual hum. it hums on my crack too. . . to fix it I turn the volume of the crack down and the submissive as well.

Can you get a reasonable listening level out of the Crack like this?  With the Crack volume control cranked all the way up, you may have a little bit of noise, but you'll also only be able to use a couple of positions on the Submissive.

If you unplug everything but the source and the Crack, does the hum remain?
