General Rules for Use
• Aim the microphone toward the desired sound source (such as the talker,
singer, or instrument) and away from unwanted sources.
• Place the microphone as close as practical to the desired sound source.
• Work close to the microphone for extra bass response.
• Use only one microphone to pick up a single sound source.
• Use the fewest number of microphones as practical.
• Keep the distance between microphones at least three times the distance from
each microphone to its source.
• Place microphones as far as possible from reflective surfaces.
• Add a windscreen when using the microphone outdoors.
• Avoid excessive handling to minimize pickup of mechanical noise and
vibration.
• Do not cover any part of the microphone grille with your hand, as this will
adversely affect microphone performance.
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.
APPLICATION SUGGESTED MICROPHONE PLACEMENT
Vocals Lips less than 15 cm (6 in.) away or touching the windscreen, on axis
to microphone.
15 to 60 cm (6 in. to 2 ft.) away from mouth, just above nose height.
20 to 60 cm (8 in. to 2 ft.) away from mouth, slightly off to one side.
90 cm to 1.8 m (3 to 6 ft.) away.

Proximity Effect

Unidirectional microphones such as the SM58 progressively boost bass frequencies by 6 to 10 dB below 100 Hz when the
microphone is at a distance of about 6 mm (1/4 in.) from the sound source. This phenomenon, known as proximity effect, can
be used to create a warmer, more powerful sound. To prevent explosive low frequency sound during close-up use, the SM58 bass
response gradually rolls off. This provides greater control and helps the user take advantage of proximity effect.

Avoiding Pickup of Unwanted Sound Sources
Place the microphone so that unwanted sound sources, such as monitors
and loudspeakers, are directly behind it. To minimize feedback and ensure
optimum rejection of unwanted sound, always test microphone placement
before a performance.
TONE QUALITY
Robust sound, emphasized bass, maximum isolation from other sources.
Natural sound, reduced bass.
Natural sound, reduced bass and minimal "s" sounds.
