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.

X-out your ground hum with ease!

All I can say is WOW! I purchased this product as a special order through Sweetwater right after it was released, and it works perfectly!


I run live sound for a mobile church. We're in two different buildings every single week, so we set up our entire sound system twice every week. We need gear that is light, compact, effective, and innexpensive. The Ebtech Hum-X is exactly those things! We used to have ground loop hum every single week because of the nature of our setup. We have a really long snake running to the back of the room where our sound board is. So all of the board stuff runs on one electrical circuit and all of the stage equipment and amps run on a different circuit. We ended up just putting a ground lift adapter on the power strip that connects the amps to the wall outlet. But that is dangerous to both equipment and its operators.


After we blew an amp and two monitors one day, I decided it was time to find a better solution to our hum problem besides a ground lift. I was looking for a 'magic black box' that would keep our gear safe AND eliminate hum without having to mount yet another piece of rack gear, run more cables, and spend a lot of money. I found the Hum-X, and it was exactly what I was looking for. My Sweetwater sales agent helped me get the product quickly even though it wasn't in stock yet, and we have been amazed at how clear and absolutely hum-free our sound system is ever since! The first day that we used it, our worship leader didn't know the system was on, since he was so used to his monitors humming at him! BUY THE HUM-X! You'll be happy you did!
