Eq800 Control Box Whine?

[garikfox]

I was noticing "coil whine" coming from the control box. I'm sure it's normal but was wondering does anyone else hear this? very high pitched squeal or whine, very faint. I also have a GM1000 and I don't hear it on that one.

Edit: Interesting! Seems to be more prevalent when using Multi.

Yep. I’ve noticed it when leaning near the unit.

Have that too, faint hiss.  Sound of switching power ouput.

I hate whines, would much rather have wines at the end of a good hunt.  Have not noticed that on my 800.
