Hum Eliminator™
Silence AC Hum, forever!
Do you hear a hum or buzz in your audio
signal? Are long unbalanced lines across
stage creating noise problems? Get the
Hum Eliminator™ from Ebtech®.
Almost all AC hum (60Hz in the US, 50 Hz in
most other countries), is caused by ground
loops. These ground loops act like radio
antennae picking up hum and noise. The
Hum Eliminator™ completely eliminates this
by breaking the ground loop, making it
impossible for the signal lines to pick up the
AC hum and noise in the first place.
Just plug the Hum Eliminator™ in the signal
lines between the offending pieces of
equipment and you’re done! Quick and
easy.
No buzz, no hum. No signal degradation. No
filtering. No noise gates. No dangerous
ground lifts.
Line Level Shifter™
Solve your –10dBV to +4dBu problems,
now!
What do you do when you need to connect a
low volume –10dBV output (like cassette
deck, CD player or synthesizer) into a high
volume, +4dBu input (like a multi-track
recorder or DAT machine)? Get the Line
Level Shifter™ from Ebtech®
The Line Level Shifter™ uses the physics of
inductance and impedance matching to
increase or decrease the signal voltage
without the added noise of active
electronics. The Line Level Shifter™ also
converts back and forth between balanced
and unbalanced signals automatically. This
is great because most –10dBV signals are
unbalanced while most +4dBu signals are
balanced.
The Line Level Shifter™ also contains
Ebtech’s Hum Eliminator™ technology to
break ground loops that cause AC hum.
Both the Hum Eliminator™ and Line Level Shifter™ are used around the world for…
Recording Studios – Audio / Video Production – Stereo / Home Entertainment Systems
Live Sound Reinforcement – Computer / Multimedia Audio – Radio / TV Broadcasts
DJ Setups – Karaoke – Car / Boat Engine Noise
