INTRODUCTION
Thank you for your purchase of the HE18 Buzz Off. If you’ve got
hum or buzz in your audio signal, the HE18 is the solution you
need. Almost all AC hum is caused by ground loops. These ground
loops act like radio antennae, picking up hum and noise. The HE18
removes many causes of noise by eliminating the ground potential.
INSPECTION
1. Unpack and Inspect the HE18 package
Your HE18 was carefully packed at the factory in a protective
carton. Nonetheless, be sure to examine the unit and the carton
for any signs of damage that may have occurred during shipping. If
obvious physical damage is noticed, contact the carrier immediately
to make a damage claim. We suggest saving the shipping carton
and packing materials for safely transporting the unit in the future.

OPERATION
To insert the HE18 in a system with a buzz or hum, discon-
nect the device you suspect is causing the noise. Connect
that device’s Output to either of the Inputs (1/4” or RCA), and
connect the HE18 Output(s) to the next device in the signal
chain.
For example; if you’ve got a buzz in your video system, con-
nect the HE18 between the video unit and amplifier to isolate
the signals.
PLEASE NOTE: THE HE18 IS INTENDED TO RECEIVE

A MICROPHONE LEVEL SIGNAL OR A SPEAKER (POW-
ERED) LEVEL SIGNAL TO THIS UNIT.
CONNECTING A SPEAKER LEVEL SIGNAL (ie. THE
OUTPUT OF A POWER AMPLIFIER) WILL CAUSE PER-
MANENT DAMAGE TO THE HE18.
