SM87A
SUPERCARDIOID CONDENSER MICROPHONE
The Shure Model SM87A is a professional-quality, hand-
held condenser microphone for use in sound reinforcement,
broadcasting, and studio recording installations. Its super-
cardioid polar pattern provides greater rejection of unwanted
sound sources, making it ideal for miking individual instru-
ments in a multi-microphone setting or for miking single
sources in a reverberant or noisy environment.
The SM87A features a controlled low-frequency roll-off tai-
lored for optimum performance when close-miking sound
sources. An integral three-stage wind and pop filter protects
against wind and breath noise. Its built-in shock mount re-
duces stand and handling noise. The SM87A operates on
phantom power.

APPLICATION AND PLACEMENT
Some of the most common applications and placement tech-
niques are listed in the following table. Keep in mind that micro-
phone technique is largely a matter of personal taste—there is
no one "correct" microphone position.
SUGGESTED MICROPHONE
PLACEMENT
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.
General Rules for Microphone Use
1. Aim the microphone toward the desired sound source and at
a 125° angle away from unwanted sources. Don't place un-
wanted sound sources directly to the rear of the microphone
since supercardioid microphones, such as the SM87A, have
a narrow pick up range at about 180°. Refer to Figure 1.
2. Place the microphone as close as practical to the desired
sound source. Refer to the table above.
3. Use only one microphone for each sound source.
4. Keep the distance between microphones at least three times
the distance from each source to its microphone.
5. Place microphones as far as possible from reflective sur-
faces.
6. Work close to the microphone for extra bass response.
7. Use the fewest number of microphones as is practical.
8. Add a windscreen when using the microphone outdoors.
9. Avoid excessive handling to minimize pick up of mechanical
noise and vibration.
10. Do not cover any part of the grille with your hand.
