BETA 181 Side-Address Condenser Microphone
General Description
The Shure Beta 181 is an ultra-compact, side-
address, condenser microphone, designed for
discreet placement in live and studio environ-
ments. Featuring interchangeable cardioid,
supercardioid, omnidirectional and bidirectional
capsules for superior versatility, the small dia-
phragm of the Beta 181 provides superior audio
with consistent, “textbook” polar responses in
a form factor small enough to get close to the
source in the tightest conditions.

General Rules for Use
•
Aim the microphone toward the desired sound source; angle unwanted sounds toward its
null
point.
•
Use the fewest amount of microphones as practical to increase the
Potential Acoustic Gain
and
prevent feedback.
•
Follow the
3 to 1 Rule
by spacing each microphone by at least three times the distance to its
source to reduce
Phase Cancellation
.
•
Place microphones as far as possible from reflective surfaces to reduce
Comb Filtering
.
•
When using directional microphones, work closely to the microphone for extra bass response to
take advantage of
Proximity Effect
.
•
Avoid excessive handling to minimize pickup of mechanical noise and vibration.
•
Do not cover any part of the microphone grille, as this will adversely affect microphone
performance.
•
Add a windscreen when using the microphone outdoors.
The following table lists the most common applications and placement techniques. Keep in mind
that microphone technique is largely a matter of personal taste; there is no one “correct” microphone
position.

Note:
As with all bidirectional microphones, sounds picked up from the back will be out of polarity
with the source. Those from the front are in polarity with the source.
