MODEL SM58£
UNIDIRECTIONAL DYNAMIC MICROPHONE
The Shure SM58£is a unidirectional (cardioid) dynamic vo-
cal microphone designed for professonal vocal use in sound re-
inforcement and studio recording. A highly effective, built-in,
spherical filter minimizes wind and breath “pop” noise. A car-
dioid pickup pattern isolates the main sound source while mini-
mizing unwanted background noise. The SM58 has a tailored
vocal response for a sound which is a world standard. Rugged
construction, a proven shock mount system, and a steel mesh
grille ensure that even with rough handling, the SM58 will per-
form consistently. Outdoors or indoors, singing or speech—the
SM58 is the overwhelming choice of professionals worldwide.

PROXIMITY EFFECT
When the sound source is less than 6 mm (1/4in.) from the
microphone, the microphone boosts bass frequencies (by 6 to
10 dB at 100 Hz), creating a warmer and richer bass sound
than when farther away. This effect, known as proximity effect,
happens only in unidirectional dynamic microphones like the
SM58. The SM58 low-frequency roll-off provides greater con-
trol, allowing the user to take full advantage of proximity effect.
APPLICATIONS AND PLACEMENT
The SM58 is ideal for close-up vocals and can be held in the
hand or mounted on a stand. Some of the most common applica-
tions and placement techniques are listed in the following table.
Keep in mind that microphone technique is largely a matter of
personal taste—there is no one “correct” microphone position.

STAGE MONITOR & P.A. LOUDSPEAKER PLACEMENT
Place the stage monitor directly behind the microphone (see
Figure 1). Locate the P.A. loudspeakers so that they point away
from the rear of the microphone. With the speakers located in
these positions, the possibility of feedback is greatly reduced.
Always check the stage setup before a performance to ensure
optimum placement of microphone and monitors.

GENERAL RULES FOR MICROPHONE USE
1. Aim the microphone toward the desired sound source and
away from unwanted sources.
2. Locate the microphone as close as practical to the desired
sound source.
3. Work close to the microphone for extra bass response.
4. Use only one microphone per sound source.
5. Locate microphones at least three times as far from other
microphones as from the sound source.
6. Use as few microphones as practical.
7. Place microphones far from sound-reflecting surfaces.
8. Add a windscreen when using the microphone outdoors, for
closeup speech, or vocals.
9. Avoid excessive handling to minimize mechanical noise.
