I purchased this box and after plugging it in, it seems very noisy. Is this normal???

A hum that you can hear is normal. If it is loud, something is wrong. If it is noisy without a load connected, I would replace it. Are you sure you have not overloaded it?

Yes it does have a hum to it. Is is on metal or wood. Ours is on wood and in the garage so we don't hear it unless we r in there. Hope this helps

It has a hum, but it is outside, so I don't hear it unless I am close to it (within a few feet).

Yes, these units have a rather strong humming sound when the power is going to the lights. Mine is mounted outside and not near any open window, so it is no bother. If yours is making noise through the wall, you might want to put some soft foam between the unit and the wall to isolate the vibration.

I have the same problem it concerns me that it may blow the circuit out! Don't know if its normal or not! My solution is to leave it plugged in and to try not to have to plug it in again.

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

Yes. I think it is normal. Mine does the same thing. Unfortunately the manual doesn't bother to mention it.

I also just bought the laptop and I am hearing this weird clicking sounds constantly! I called tech support and they said it was part of the HDD Protection Settings, so I turned it off and the noise stopped briefly but came back. I think I will have to call again because this is noisier than the 2007 laptop I had before. If it doesn't stop I will return the laptop.

no. it's not normal. something is loose in the speaker/broken inside, maybe a piece of wood from the speaker and that might be what is moving around. nothing should be moving around inside the speaker box. however, how is the sound? do you hear any crackling? any funny noise? anything out of the ordinary?

I didn't notice any unusual Buzz when I first powered up the unit in my shop. My opinion is is the noise level is normal....

Not normal! No motor noise, maybe just a hum. Unless the motor is not stationed firmly and is maybe vibrating, I would return. Mine is so quiet, I sometimes forget it is there until I here running water!

No idea, check your install and make sure it's well supported, mine has no noise like that.

I have the same version but with a metal chassis and noticed this whine. I'm going to look into a replacement. It makes the noise about 20 seconds after plugging in the power.

Tried mine last night for the first time, makes so much noise that I had to go back to my old unit. Will try again in a different area and see if that helps

No, not normal - Have you checked your wiring, ground, etc? Are the green and blue lights glowing properly? I have two of the surge protectors- One since 2003 and there is no hum... I would return it.... Monster Cable will not honor a warranty by a seller they do not certify. Amazon is certified, but most of the merchants selling the product at a cheaper price are not.

I'd send it back if you can--I've had mine for a while and it oscillates just fine with no noise other than WD40 I wouldn't know what to do to it.

no it is not normal. I get the hissing sound until i turn off the puck(i.e. I touch it). The hissing with power on appears to happen with most computers and speakers, until the speakers are turned off.

Mine does not have this high pitch you're talking about, just a loud hum, rather like a window air-condition unit. Since it is in my basement, it does not bother me. Maybe you have a bad unit?

I have not had that problem. It sounds like a bad power switch or loose connection on the power supply. I would return it and get a replacement if you can. Mine has worked great for several hours of use so far.

When I turned it on the first time, I thought there was something wrong with it because I could barely hear that it was running. Needless to say, the noise level should not be an issue. :)
