      This item did not clear up any hum in my lines at all. I have a bad ac hum, that I believe is caused by electrical dimmer light switches that run not to far from the shielded speaker cables I am using. With the eliminator in the line, I notice no difference. Perhaps this is not the right application for this device?

        Comments about Behringer MicroHD HD400 Hum Eliminator:

        I own a big production studio with many synthesizers even vintage ones which mostly given me the hum problems. The best thing about this is, you just plug it in and it knocks the hum out right away without losing sound quality from my synths. Nothing technical. Just make sure you have TRS cables for the ins & outs in order for this to really work. If your on a budget or not, this thing works regarless.

                  I used this simple box in line between my roland UA-25EX USB interface and my monitors. I had bad line hum and the ground lift switch on the roland made no difference. The HD400 kills the hum...nuf said!

                        This product works like it says. Suppresses hum from ground loops. Used it on a noisy DVD player going into the sound board. Completely eliminated all the hum and buzz. Can't speak for it's longevity as I've only had it less than a month. So far, so good.

                          I've always had trouble with humming in buzzing in my home studio. The combination of an older house and close proximity to a big radio tower probably had a lot to do with it. This simple little device has really done the trick to significantly reduce hum & buzz for both instruments (electric guitar/bass) and microphones. Great product.

                          We needed a bad hum elimanted that was being caused between the audio out from video deck to the main audio system---no amount of ground lifts worked but this little box did the trick. We are buying 2 more for other areas where we have virtually unsolveable ground differences that are causing audio hums. Price / performance is unbeatable. One of the good pieces of gear from Behringer!
