Reducing Humming Sound

Hello all!

I am using a Tripp-Lite LCR2400 AC line conditioner in my system.  I am very happy with it and the peace of mind it offers me with regards to not only protecting my equipment, but insuring the power I'm getting is clean and stable.

This unit is known to have an audible hum to it...it's not very loud, but it can be heard faintly in a quiet room. When playing music, the hum is not noticeable at all.

If I were to attempt to reduce this hum, would opening the unit up and affixing sound deadening material (like Dynamat) to the interior of the case/chasis/cover be a good solution?  Normally, I would go ahead and give this a try, but since there is such a high level of electricity being handled by this unit, I don't want to do anything that would be dangerous once I plug it in and turn it back on.

Thanks for any feedback,

Arvin

Coils and especially large transformers will hum.  Some equipment is damped and isolated much better than others.  This is why well designed, well made transformers are extremely expensive.

I have had several conditioners that hummed loudly and in every case, it was the transformers.  Had to get rid of them.

There are power conditioners in the market that are very quiet and work quite nicely.
