MODEL SM57
UNIDIRECTIONAL DYNAMIC MICROPHONE
The Shure SM57 unidirectional dynamic microphone is
exceptional for musical instrument pickup or for vocals. With its
bright, clean sound and carefully contoured presence rise, the
SM57 is ideal for live sound reinforcement and recording. It has an
extremely effective cardioid pickup pattern which isolates the main
sound source while minimizing background noise. In the studio, it
is excellent for recording drums, guitar, and woodwinds. For
musical instruments or vocals, the SM57 is a consistent choice of
professional performers.

Supplied break-resistant swivel adapter that rotates 180°
Legendary Shure quality, ruggedness, and reliability
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.

APPLICATION AND PLACEMENT
Some of the most common applications and placement techniques
for the SM57 are listed in the following table. Remember that mi-
crophone technique is largely a matter of personal taste-there is no
single “correct” microphone position.
PROXIMITY EFFECT
When the sound source is less than 6 mm (1/4 in.) 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 in
unidirectional microphones like the SM57. The SM57
low-frequency roll-off provides greater control, allowing the user to
take full advantage of proximity effect.
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 multiple 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 away 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.
