Is it normal for it to hum somewhat loudly when on but no source is input? It hums and the woofer is vibrating.

No, Do check everything others have mentioned. Also make sure your receiver is correctly configured. Run a sound test to help pinpoint your issue.

Make sure you have the speaker's volume control at the medium level or lower, and keep the ON control to Auto. The other thing that may be wrong is the Polarity, make sure the plus side of the amp goes to the plus side of the speaker and likewise for the negative. .............. Hope this helps.

Not normal at all. Several issues can cause this, i.e. bad grounding, poor shielding, RFI or EMI from nearby devices/outlets/power wires, faulty amplifier, etc. I personally have 2 F12's and have sold several more to customers and have never had an issue with them.

no, this is not normal. make sure that the unit is properly connected to a source and grounded.

Is it a ground hum? Because if the speaker has a hum, there is nothing wrong with the speaker itself.

I have no idea as to why. I have never experienced that problem. The only issue I ever had was when the volume level of the sub-woofer was turned up to loud and I didn't realize it, LOL. Did you contact LG and see if they had a solution?

I heard a lot of noise as well, that is before i bought a dedicated audio interface, like an m-audio m-track, preSonus, focusrite, etc.. If you're not using one, then i'd say get that first. I have no noise now at all settings. From -30db, and i usually have my speakers set at the +6db and nothing. i'm also using the 1/4" to 1/4" plug into the balanced inputs. If you're using an audio interface, then i'd say call customer support and get it fixed.

Sounds like it's too much squelch. Turn it up until you have a constant static, then back it off until there's nothing. That's what we did and we don't have that problem.

Mine does not hum, I use it as an automatic transfer switch in the living room, it's been on 24 hrs a day for a month with zero noise. I would return it and try another one.

Yes! I get this annoying hum that only goes (mostly) away if the bass control is all the way down. The volume control has no effect and it doesn't matter if the satellite speakers are plugged in or not. I wanted to put this next to my bed but the hum is intolerable. I plan to return it. I don't know if I should try getting a replacement or if I should give up on this model entirely.I got a replacement and it is worse. It buzzes even with the power off. With the power on I can hear the hum across the (quiet) room. When it is close enough to reach the control from my bed, the hum drives me crazy. Yes!

I've had no problem with hum,Sometimes hum is caused by unshielded wires too close to speaker wires, or power cords too close to wires.Sometimes wires have defective shielding.Did you ever have a ungrounded turntable that caused a low hum??Anyway,check your wiring.If it happens on any input maybe it's wiring near speaker cables.If it happens on only 1 input replace those cables!!Not a design flaw!!Good Luck!! Dave & B.H.'s answers makes a lot of sense also!!

My turntable does not have a hum. A feedback hum is produced through the system at loud volume but that's my fault because I have it sitting on a hollow cabinet, my cartridge is really sensitive and that's the exact same thing as a supersensitive stage mike...I expect the feedback hum. But there is no hum from the motor or anything on the turntable itself

A replacement cable may be needed; make sure it's balanced otherwise you'll keep getting a humming or buzzing. Best suggestion I have, always a good place to start though.

Mine, too, made a loud pop every time I turned it on. However, it was working otherwise until it lost connection to the subwoofer and started making the clicking (or popping) noise every second or so. None of my ideas for addressing the problem worked except for returning the unit to Amazon, which I am doing.

I don't think I've heard any on mine. If you are hearing the hum while using the RCA jacks then maybe trying unplugging it from USB/have the turntable and speakers on separate outlets. If you are hearing it over USB then maybe just try the same isolation but between the computer and the turntable.

I found that making sure there was no interference from any other electronics nearby helped. Just experiment with moving the unit, the input cable, and the source of your sound (whatever you're broadcasting) around until you find the sweet spot. I've got virtually no hum now, but occasionally I'll hear some and invariably find that someone has moved one of the elements around. Once I put it back where it belongs, no more hum.

It produces a low hum. It may not be enough noise if you are in a fairly noisy location, though.

Do the lights show that the bar "thinks" it's off? (ie, it really does turn off). There are some wires connecting this to your audio source - if you disconnect them, does that cause any change? (also, as with any electronics, you might try unplugging, wait 20 seconds, then replug in). I can't think of a good reason for such a noise other than the unit dying, but these things might prove it.

It sounds like you must have a defective unit. I don't get a hum with either tubes or solid state amp. Sorry yours is making bad noises.

It has a slight hum, but not noticeably loud. I've had it for about 6 months, and there's nothing I would complain about it
