OVERVIEW

A quick and easy way to eliminate AC hum and noise.

The Ebtech 2-Channel Hum Eliminator is a quick-and-easy way to eliminate AC hum and noise. Insert the Hum Eliminator in the line-level signal path after your preamp and it will break noisy ground loops without degrading your signal. Use it on long unbalanced lines that are especially vulnerable to noise. Many mixers don't have balanced monitor outs and aux sends, but you can make them quiet using Ebtech's Hum Eliminator. Includes 1/4" TRS smart jacks that convert automatically back and forth between balanced and unbalanced lines. Made in the USA.

This product does an EXCELLENT job for it's *intended* purpose - it electrically isolates connections between two pieces of gear. It's NOT a noise reducer for gtr distortion pedals (for that task, consider a unit like the Rocktron HUSH or a gate like the Boss NS2 or MXR M-135). A typical application where the Ebtech is used would be to connect the line-out of a bass head through the Ebtech to the PA. Often times, the PA and the bass amp will be powered on different 'mains' circuits - that is the source of 'ground loop hum'. The Ebtech uses a transformer to pass the signal magnetically with no electrical connection. In doing so, it breaks the loop and eliminates the hum. It is MUCH safer than the other common solution - using a ground lifter on either the PA or the bass amp. I keep the Ebtech in my gig bag along with an inexpensive plugin type AC outlet circuit tester. They are indispensable tools in maintaining safety and eliminating noise at gigs.

I bought this thing a while back and it didnt work at all. I used to use a wall wort to power 13 pedals no my board and was very confident that this would solve my problem. Unfortunately it only added more buzzing to my signal and beleived I may have purchased a dud. Eventually I bought the 1spot adapter and that solved my problem, to a degree. Perhaps later on, I'll buy another and hope it works for me.

This thing works

About Me Experienced

Comments about Ebtech 2-Channel Hum Eliminator:

Playing electric guitar setup with Furman powered pedalboard thru Fender '57 Twin. First pedal on the board is a TC Helicon Harmony GXT, followed by Fulltone OCD, and several other pedals. Awful hum thru the amp, regardless of powering pedals via the board (w/ 12V wall wart plugged into board for Harmony GXT) or Voodoo Lab Pedal Power. Removed the Harmony GXT and plugged direct into the OCD and no hum, so I knew the Harmony GXT was the culprit. I had purchased this Ebtech years ago and forgot I had it. I tried plugging it in between the Harmony GXT and the OCD, and BINGO - the hum is gone. Works great.

    Does it's job, but...

    By ace_man

    from PHX

    Comments about Ebtech 2-Channel Hum Eliminator:

    this thing does exactly what I bought it for, but when i use it, it seems to drastically cut the sound signal- basically making me turn up the volume even more, just to get heard... it definately gets rid of that annoying buz from ground loops, but beware that if you don't have any headroom as far as volume goes, you will be dissapointed...

    By Anonymous

    Comments about Ebtech 2-Channel Hum Eliminator:

    im in a band that does many live shows and i always have a problem with feed back and even with my noise suppressor i still get a ground hum. this thing works perfectly but if you are using a head like mine (i have a peavey valve king) your gound hum is most likely cased by the plug not by any loop so this has no value at all. if this is you i recommend the Ebtech Hum X Hum Exterminator. im ganna return this and get that

    The Ebtech Hum Eliminator

    By Sean Aguinaga

    from Hampton, NH

    Comments about Ebtech 2-Channel Hum Eliminator:

    This device reduced my 60HZ cycle hum about 75%. I use a SansAmp PSA-1 pre-amp, a tubeworks power amp, and a les paul special. I placed the hum eliminator between the les paul and the SansAmp.

    By Nate Ritter

    from Stevens Point, WI

    Comments about Ebtech 2-Channel Hum Eliminator:

    The Hum Eliminator was just what I needed to get rid of that nasty 60hz hum I had going on from a ground loop. I couldn't get rid of it for the life of me.
