Eliminate The Hum - Not Your Sound!

Exterminate hum with the Hum X! This handy tool filters out unwanted voltage and current in the ground line, which can cause ground-loop hum, while simultaneously maintaining a solid, safe ground. Some devices simply remove the ground, which is never safe! You'll no longer have to run your audio signal through any type of filtering or ground lift, which can result in loss of volume or tone, or both. The Hum X is easy to use, easy to install, and best of all, Hum X makes you sound better! Hum X can be used with any device with a 3-prong outlet and doesn't draw more than 6A of power.

Ebtech Hum X Ground Loop Eliminator Features at a Glance:
  • Eliminates ground loop hum
  • Maintains safe, solid ground
  • Avoids loss of volume, tone or both in your audio signal
  • Plugs conveniently into your power cord and wall outlet

The Hum X are real good for cleaning ferrite screens. Place a ferrite screen or two halfway between your light switches and ceiling light/fan, then plug a Hum X into a nearby outlet and the hum will come out of your ceiling light in 7 days.

Saved a full band session

I didn't realize how useful this could be until three years after I'd bought it. I was running a pair of focusrite rackmount units, linked via ADAT, recording a full band. And despite my best efforts up to now, I started to get some pervasive hum/interference in the DI bass track. We tried three different basses, all with the same noisy result. I grabbed this thing from my old pedal board, plugged one of the rackmount power cables into it, and the hum was completely gone! If I didn't have this, I could have spent a great deal more time completely rearranging all of my power needs, and I could have screwed up the entire session.

It totally eliminated my laptop ground loop noise/buzz!

I was getting noise when running an output from my Torq Xponent into my main PC sound card. I knew what was causing the noise, but I really didn't want to use a 3-prong to 2-prong adapter to totally lift the ground from my laptop because it's not completely safe, so I chose this little gem to see if it would do the job. It got rid of every bit of the noise and now my shoutcast streams sound crisp and clean again. Laptop noise is common with laptops that use a 3-prong plug. If you have this problem, I highly recommend trying the Hum X. If it doesn't work for your situation, Sweetwater has one of the best return policies in the industry and will take care of you with excellent/courteous customer service.

Great Hum killer

I had an untraceable hum going on and I could not localize it . I checked my pedals, my amp, and my guitar and still couldn't find it. But after plugging the HumX ground Loop in the hum was gone!

Fantastic! I was getting a horrible ground loop when re-amping with my laptop, Mackie Onyx Satellite, Little Labs Redeye (passive unit), and Peavey JSX. Unplugging the laptop (running it on the battery) made the noise go away, but that's hardly a workable solution, so I bought the Hum X, put it between the wall and my JSX's power cable, and BAM! Hum X'ed! Thanks Ebtech, works perfectly, and without having to put anything in the signal path!
