Ebtech HUM X overview

  • 1Description

The Hum X from Ebtech is a safe and economical way to get rid of ground loop hum. It works by placing the unit on the end of the power cord of the equipment that has a ground loop and then plugging the Hum X into any standard 15 amp outlet.

The Hum X filters out unwanted voltage and current in the ground line that cause ground loop hum, while simultaneously maintaining a solid, safe ground. Audio signals no longer need be run through any type of filtering which can result in loss of volume, tone or both.

Some devices simply remove the ground, which is never safe. The Hum X is easy to use, easy to install, safe and completely effective.

    Ebtech HUM X reviews

    Hum X Ground Loop Hum Eliminator is rated 4.3 out of 5 by 100.
    Rated 4 out of 5 by from I think it works I think this puppy works. Not sure if you need to plug it directly to the power cable of the device in question, or if it can be used on the outlet directly and plugged into a power strip. I have it in the outlet with all my electronics plugged into the power strip. It works ok, it cuts some of the hum at certain volume levels just enough that it doesn't annoy me anymore. Better idea - use this in conjunction with a balanced outlet, get a nice solid desk or workspace to put your devices on so nothing vibrates and make sure everything is nice a grounded, speaker monitors are on pads, etc. A combination of these things will remove the hum from your monitoring setup.

    Rated 5 out of 5 by from It works! I'm doing audio mixing work, using a laptop into an Edirol firewire audio box into powered studio monitors. When I use the laptop's power supply, I get a horrible hum mixed with a screeching noise in the monitors. If I run the laptop on battery power or use a ground lift (2-prong adapter - not recommended) for the power supply, the noise mostly goes away. So I deduced that the noise was introduced by the laptop power supply via the ground pin.I picked up the HumX at B&H and plugged the laptop power supply into it. Noise GONE! The monitors are dead silent. Best $ I ever spent.

    Rated 4 out of 5 by from Read up on Ground Loops Before You Buy.. I bought this based on many positive reviews, but it did not eliminate the hum in my AV camcorder/powered mixer setup. I tried plugging it in on every power cord, but could not isolate the issue. I suspect my problem is bigger than what this device can do on its own, and I was trying to put a band-aid on a bigger wound than it was designed for. I would still recommend this to others if they know the specific source of the ground loop, and I may purchase one again in the future for simple on-location uses. As for my current set-up, I will just keep running my camcorder on battery power for the time being.

    Rated 5 out of 5 by from Hum X is a Good Name for this product This device works very well. It does exactly what it is supposed to do with a simple install. When first using this device I needed to isolate the ground loop source which actually took me several attempts. The real issue with complex MIDI equipment and computers-old equipment matched with newer equipment, and components that actually have a grounded plug vs. those that do not have a grounded plug. The Ebtech Hum X will only work with a grounded plug, so by trial and error I found the culprit component and the ground loop Hum is no longer an issue in my audio mix.. A great relief after many attempts with inline ground loop isolators and TRS vs. TS vs. RCA plugs.. A sense of accomplishment is always good, I think..

    Rated 5 out of 5 by from Ground Loop hum no more The Hum-X eliminates 97% of the ground loop hum. I have a Primaluna tube seperate pre-amp/amp the hum was very audiable. After I plugged the Hum-X into the amp it worked...but if you put your ear to the speaker you can still hear a faint hum thats why I say it eliminates 97% of the hum. Note: the instructions say you should have a plug for each piece of equiptment for best results. So I bought another Hum-X for the pre-amp. Also I have read reviews where people just plug into a power strip , this is not recommended it should not be used on equiptment exceeding 6 amps! Make sure you read the short instructions included in the package! over all I am very satisfied! the price was right at B&H.....

    Rated 5 out of 5 by from It Works After replacing the internal amp on the sub-woofer with little success in eliminating the HUM I stumbled accross this device on the internet. I figured nothing to lose at this point and ordered it online. ..., plugged it in and NO HUM, its a miracle!!! I worked on this problem for over one year trying everthing I and others suggested with no luck. Thank You. This should be advertized or sold where subs are sold as this problem is common to this type of equipment.

    Rated 1 out of 5 by from Plugged it in and voila - no difference! I plugged my multi-outlet box into it and it into the wall (so I could keep the hum out with a mixer and two timecode-slaved recording decks) and the hum was still there - not eliminated - not even reduced. Does it say that this will only work with a single device plugged into it and not an outlet box? If so I will remove this review and chalk it up to user error. At any rate I was severely disappointed by the lack of results, since I have several audio devices plugged in for recording video projects on location and have to switch to eating up a huge number of batteries to eliminate the hum.

    Rated 5 out of 5 by from Hum X Eliminated the Ground Loop!! I had a variety of audio and video gear set up for legal video. After plenty of trial and error, I narrowed down my audio mixer to be the culprit causing the ground loop (otherwise known as a hum or buzzing in the audio). I read positive reviews on this item, and it was the least expensive device I could find that would stop ground loops, so I decided to order it. When I plugged the Hum X in between my power strip and audio mixer, the hum was gone!!! If you have audio/or video ground loop hum issues, I definitely recommend trying this device.
