• Crisp frequency response
• Fast transient response
• Tight cardioid polar pattern for isolation
• Superb rejection of off-axis information
• High-output self-biased condenser element
General Description:
Thank you for purchasing the Electro-Voice® PL37. This product is
a professional-grade tight cardioid condenser microphone designed
to deliver all of the crisp detail of cymbals, high-hats and percussion
instruments in any size sound reinforcement system or recording
studio. With its frequency response designed for overhead drum set
and percussion miking, the PL37 delivers all of the “dialed-in” tone
and percussive transient response detail professional drummers and
sound system engineers require. The PL37’s tight cardioid polar pattern is designed to minimize off-axis information from nearby stage
instruments entering the capsule, and allows for a clean drum set
sound and higher gain before feedback. Although designed to be an
overhead drum set and percussion microphone, the PL37 can also
be used as an acoustic instrument microphone in applications where
a condenser element capsule would be desired.

Application Notes:
1) This product requires external power to function (see technical
specifications panel for voltage spec), which is commonly supplied
via the Phantom Power function on your sound system mixer or
input module.
2) As with most directional microphones, the low frequency response of the PL37 microphone varies with the distance from the
sound source. Known as “proximity effect”, the bass response of the
microphone increases as the working distance to the microphone is
reduced. This “bass boost” is only audible when working at distances
closer than 6 inches. Therefore, working close to the microphone will
produce a more robust sound. Using this microphone at distances
greater than 6 inches provides minimal coloration from proximity
effect.
Close-up positioning of the microphone will also reduce the potential for feedback from the sound reinforcement system. Then, the
bass boost provides an increase in overall microphone output level.
The mixer gain may be proportionately reduced, resulting in a reduction of the system’s sensitivity to feedback caused by sound entering
the microphone from the loudspeakers.
Max SPL (1% THD @1 kHz): 132 dB SPL
Warranty:
This Electro-Voice® PL37 product is guaranteed against malfunction
due to defects in materials or workmanship for a period of three (3)
years from the date of original purchase. Please refer to the Limited
Warranty card included with your product for further warranty information.

Microphone Use and Placement
Please note that micing techniques are a matter of personal
preference. These are merely guidelines to assist in the
placement of the microphone to gain optimal performance.
Usage Optimal Placement
Overheads Use two microphones in a 3:1 spacing position facing slightly away from each other.
High-Hat Place microphone 3 to 6 inches from and at a 45° angle to cymbal edges.
Acoustic Guitar Place microphone 6 to 24 inches from and pointed towards body end of finger board.
Strings For small string instruments, place microphone 1 to 3 feet from and perpendicular to the soundboard,
pointing at the strings and f holes. Use similar microphone positioning for larger string instruments, but
6 to 8 feet away.
Standard Placement & Use Guidelines
1. Always point the microphone at the desired source of sound, and away from any unwanted sources.
2. The microphone should be located close to the sound source to minimize interference from other potential sound sources.
3. Use the 3-to-1 rule when using multiple microphones. Place each microphone three times farther from other microphones as from
the desired sound source.
4. Minimize over-handling of the microphone to reduce unwanted mechanical noise.
