OWNER’S MANUAL — Please read before using this equipment.
Thank you for purchasing
the RadioShack
Omnidirectional Boundary
Microphone. It is ideal in
situations where you want
a microphone to be out of
the audience’s sight, or
where a traditional
microphone might not be
practical, such as group
meetings/conferences,
stage productions, choral
ensembles, or concerts.
The microphone’s sleek
design and rugged
construction let you easily
set it almost anywhere —
on the floor, on a table or
lectern. Its hemispherical pick-up pattern
and high sensitivity let you easily pick up
near or distant sound coming from all
around the microphone. Your microphone's
other features include:
On/Standby/Off Control with Belt Clip —
lets you conveniently turn the microphone
on and off at any time.
Wire-Mesh Windscreen — reduces wind
noise and breath pops.
Stabilized Rubber Pad — anchors the
microphone for greater stability.

The microphone uses a hemispherical pick-
up pattern, which means it picks up sound
equally from all directions within the space
(hemisphere) above and around the
microphone. Sound quality remains
consistent no matter where it originates. It
does not vary from side to side, or from top
to side.
Experiment and listen to find the best
location for the microphone. Choose what
you think is the best location, then listen to
how it sounds.
±
To achieve the best performance, improve
low frequency sound pick-up, and maximize
the microphone’s range:
• Place the microphone on a solid, flat
surface, with the top of the microphone
in the sound source’s line-of-sight so
the person speaking can see it.
• Leave at least 1 foot (.3 meter) of clear
space all around the microphone.
• If you use two or more microphones,
position them at least 20 feet (6 meters)
apart.
• Avoid positioning the microphone on
carpeting or other sound-absorbent
material.

• Use only fresh batteries of the required size
and recommended type.
• If you do not plan to use the microphone for 2
weeks or more, remove the battery. Batteries
can leak chemicals that can damage your
microphone’s electronic parts.

• Keep button-cell batteries away from
children. Swallowing a button-cell battery
can be fatal.
• Dispose of old batteries promptly and
properly. Do not burn or bury them.

Choosing a Location
• The microphone might pick up some sound
from the area behind its base (below the
plane of the mounting surface). However,
the sound quality is not as good as the
sound picked up from above and to its sides.
• If you must position the microphone on a
carpeted surface, place a 4 foot (1.2 meter)
square piece of plastic or wood on the carpet
first, then place the microphone on top of the
plastic or wood.
Connection
If your audio equipment’s microphone jack is a
1
/
4
inch (6.35 mm) type, use a
1
/
8
inch (3.5
mm) to
1
/
4
inch (6.35 mm) adapter plug
(available at your local RadioShack store).
