BETA 87Ct
cardioid Condenser Microphone
The Shure BETA 87C is a high output condenser microphone
that provides touring professionals with studio-quality sound.
Vocalists who use in-ear monitor systems such as the Shure
PSM
Personal Monitor System will appreciate how effectively
the BETA 87C rejects ambient sound from the rear of the micro-
phone.
The BETA 87C maintains its cardioid pattern throughout its fre-
quency range, ensuring maximum isolation from other sound
sources and high gain before feedback. Its warm, natural sound
is the result of an exceptionally smooth frequency response that
includes a slight presence rise. A controlled low–frequency roll-
off compensates for proximity effect and prevents the "boomy"
sound often associated with close-up use.
The BETA 87C is an excellent choice for professional studio re-
cording, yet it is built to withstand the rigors of touring. It maintains
its performance characteristics even at sound pressure levels as
high as 139 dB SPL. Plus, the cartridge is protected by a proven
shock mount system. A hardened steel mesh grille with a built-in
pop filter provides added protection.
Features:
• Smooth, wide frequency response with slight presence rise
• Cardioid polar pattern for maximum isolation
• Minimal off-axis tone coloration
• Superior gain before feedback
• Low-frequency roll-off compensates for proximity effect
• Wide dynamic range (117 dB)
• Low distortion characteristics
• Very low susceptibility to RFI and electromagnetic hum
• Advanced cartridge shock-mount system absorbs mechanical
shocks and reduces handling noise
• Built-in pop filter reduces wind and breath sounds
• Shure ruggedness and reliability for years of trouble-free
performance

APPLICATION AND PLACEMENT
The BETA 87C is ideal for applications where in-ear monitor
systems such as the Shure PSM
are used. Tone quality will vary, depending on how close the mi-
crophone is to the sound source. Keep in mind that microphone
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.
More than 60 cm (2 ft.) away.
General Rules for Microphone Use
1. Aim the microphone toward the desired sound source and
away from unwanted sources. Refer to Figure 1.
2. Place the microphone as close as practical to the desired sound
source. For extra bass response, work close to the microphone.
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. Use the fewest number of microphones as is practical.
7. Add a windscreen when using the microphone outdoors.
8. Avoid excessive handling to minimize pick up of mechanical
noise and vibration.
9. Do not cover any part of the grille with your hand.

OPERATION
Power
The BETA 87C requires phantom power. This may be sup-
plied to the microphone from an external power supply (such as
the Shure model PS1A) or directly from preamplifiers, mixers,
or consoles with built-in phantom power. Suitable sources
should provide 11 to 52 Vdc phantom voltage.
