MagniFi Mini soundbar making humming noise when in standby or off

Hello, my new MagniFi Mini sound-bar makes a high frequency humming noise when the TV is off and the unit is on standby or off (this noise not loud but definitely audible when the TV and sound are off, enough to be distracting when sitting on the couch). The sound-bar is hooked up to a Samsung UN60KU6290 with the provided HDMI cable.

Is there anything I should try to remedy this?

thanks!

    Does it hum with only the power supply hooked up?

    Mine does the same thing, but I have to be close to it to really notice. Yes, it is only with the power supply hooked up. I have 2 of them, and both do the same.

    Is that what I hear? I guess mine does it too. It's faint, but once you hear it, you can't unhear it. Only when everything is silent. I was trying to find the source of that high pitched whine last night. Thought it might have been my Dish TV receiver box.

    Yes, noise is only there with power supply hooked up. If I pull power, the noise is gone. I tried swapping power bars or going direct to receptacle on wall, this did not solve the problem.

    If these all do it I don't think it can be considered a problem, more like the nature of the beast. I can't hear mine unless I am close and the room is totally silent, which it never is.

    This would probably get to me, as well once I knew it was there.
    Maybe a switching power management center could be a solution? Have the soundbar in one of the Switched outlets that powers up when the master Always On device is powered? Like the TV, perhaps?

    I should clarify mine is more of a high pitched whine, very low level. I will check again tonight. I may be mistaken as it might be something else entirely.

    I don't get a "hum" at all. The whine is only noticeable when dead silent or very near the unit, not from the listening position under normal circumstances.

    P.s. I have heard power supplies emit a very low level high pitched whine before.

    P.s.s. I love this soundbar. Pretty much perfect for my situation. Much better than I expected it to be based on size and price.

    I agree, it's more of a "whine" than a "hum".

    It is a high pitched whine

    I had mine plugged into the wall originally. I freed up some space on my PS Dectec power center and plugged the mini into it. The high pitched whine appears to have left the building.

    Great info @motorhead43026

    Since I own 3-dectec's and they do at the least part of what they are designed for...tfs

    Good to know about the power issue. It's a shame though that PS Dectec power center costs twice as much as the MagniFi Mini :P

    Do you know of any other power supply units that could resolve this, for much less $$$?
