Hum Eliminator Ebtech


Hum Eliminator Ebtech 2 channel at DC Music. Thank you for your interest in the Hum Eliminator 2 channel. 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.


The Hum Eliminator™ does more than just prevent AC hum from being picked up by your sound systems. It also can be used as one of the most cost-effective ways to convert unbalanced signals to true balanced signals. Ground Loops – The Hum Eliminator™ prevents ground loop antennae from forming and picking up AC hum. AC hum & noise is almost always caused by a loop antenna effect across signal lines between two or more pieces of gear, or by long unbalanced cables picking up noise. Loop antenna(e) are basically a type of radio antenna, which tend to pick up the 60Hz (and harmonics) AC signal being broadcast by a building's electrical current. These loop antennae are closed circuits
usually along the ground wires and hence are commonly called ground loops.


Balanced/Unbalanced - Unbalanced signals are more susceptible to picking up electrical noise & RF interference than balanced signals are. The longer the unbalanced cable, the greater the chance of a problem. The Hum Eliminator™ is one of the most cost-effective ways to convert between unbalanced signals and true balanced signals. MIXERS/RECORDING
· Many mixers have either unbalanced or "impedance balanced" monitor outs/aux sends. Use a Hum Eliminator™ to get true balanced monitor outs for noise-free performance.
· When using more than one mixer (or submixing), there’s a huge chance of getting ground loops (and that buzz!). Use Hum Eliminators™ to prevent these ground loops.
· Eliminating hum is one of the biggest challenges facing studios. Many studios will run all of their line level gear through Hum Eliminators™ to help ensure noise-free recording.


Hum Eliminator Ebtech often can eliminate hum, buzz and noise in a sound system especially when a laptop is used with a PA system.


KEYBOARDS/SAMPLERS/SYNTHS
· Most keyboards, samplers, and synthesizers have unbalanced -10dBV outputs. Use a Hum Eliminator™ to balance
the signals if using with other –10dBV equipment.
· To use a –10dBV unbalanced device with a +4dBu balanced device, use an EBTECH® Line Level Shifter™.

LIVE SOUND/DJ MIXERS
· A common problem with live performance is long unbalanced cables picking up hum along the way. Balanced signals
are more immune to picking up noise. Use the Hum Eliminator™ to balance long unbalanced signals.
· Mobile DJs or bands never know when setting up their system if they’re going to get a hum or not. The electrical
wiring changes from one building to another. What works fine at one gig might not work at the next. It’s worth the low
cost to keep a Hum Eliminator™ available as nobody can afford to lose a gig because of hum problems. Some DJs
run everything in their rig through Hum Eliminators to play it safe.
· The main outs on most DJ mixers are -10dBV unbalanced RCA. When using with a +4dBu power amp, over 2/3rds of
the amp's volume can be lost. Use an EBTECH® Line Level Shifter™.


POWER AMPLIFIERS
· Running multiple amplifiers can create ground loops between the amplifiers, which will pick up the dreaded hum and
buzz. Run each amplifier's input line through a Hum Eliminator™ to prevent this problem.


GUITARS
· Many guitar players use rack and pedal effects. They can get buzz from ground loops that these devices create. Use
a Hum Eliminator™ to eliminate that buzz.
· When using two or more guitar amplifiers, ground loops can form between the amplifiers. Because of the tremendous
amounts of gain in guitar amps, the buzz can get so bad that the amplifiers will actually squeal (especially with tube
amplifiers). Simply run the feed to each amp through one channel of a Hum Eliminator™.


COMPUTER SOUND CARDS
· Most sound cards have unbalanced inputs and outputs. Balance these with the Hum Eliminator™.
· Even balanced sound cards have tremendous susceptibility to ground loops because of the computer's power supply.
If you hear a buzz, use a Hum Eliminator™.


BROADCASTING/VIDEO
· Press Boxes have many feeds all going to different gear; which can create lots of ground loops and hum. Use a Hum
Eliminator™ on these feeds to eliminate the problem.
· Using a Hum Eliminator™ on the audio feed of a video camera can help prevent video hum (snow). Thank you for your interest in DC Music.
