Unidirectional Condenser Microphone
Your Optimus Unidirectional Condenser
Microphone delivers acoustic clarity and
accuracy. The unidirectional pickup pat-
tern controls feedback, reduces pickup
of undesired si
nals and provides in-
creased sensitivity. Your microphone is
intended for use in hi
h-quality recordin
and sound-reinforcement applications
where wide, smooth frequency response
is needed. Its features include:
Flat Frequency Response
— offers
faithful sound pickup.
Recessed On/Off Switch
— helps pre-
vent you from accidentally turnin
your
microphone on or off.
Unidirectional Polar Pickup Pattern
—
reduces feedback and pickup of unwant-
ed si
nals.
Balanced Low-Impedance Output
—
compatible with professional or amateur
equipment with a phone jack. (You need
an adapter, available from your local Ra-
dioShack store, to use the microphone
with equipment that has an XLR input.)
Wire-Mesh Windscreen —
reduces
wind noise and breath pops. To further
reduce wind/breathin
noise, use an ad-
ditional windscreen, such as Cat. No. 33-
378.
Included Accessories
16-Foot Cable with 3-Pin (XLR) Con-
nector
— for easy connection to profes-
sional-quality public address systems
with unbalanced mic hookups.
Microphone Holder
— lets you use the
microphone with a stand.
INSTALLING A BATTERY
You need one AA battery (not supplied)
to power your microphone. We recom-
mend an alkaline battery, such as Cat.
No. 23-552.
1. Unscrew the microphone’s lower
case.
2. Install the AA battery accordin
to
the polarity symbols (+ and –)
marked inside the battery compart-
ment.
USING THE
MICROPHONE
To turn on the microphone, slide the mi-
crophone’s switch to
ON
.
To temporarily disable the microphone
(without hearin
a “pop” when you turn it
off), slide the switch to
STBY
(standby).
Slide the switch to
OFF
to turn the micro-
phone off when you are not usin
it.
