PL37

Cardioid Condenser

Overhead Microphone

General Description:

Technical Specifications:

Key Features:

• Voiced for overhead cymbals, high-hat and percussion

• Crisp frequency response

• Fast transient response

• Tight cardioid polar pattern for isolation

• Superb rejection of off-axis information

• High-output self-biased condenser element

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 pat-

tern 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 re-

sponse 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 poten-

tial 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 reduc-

tion of the system’s sensitivity to feedback caused by sound entering

the microphone from the loudspeakers.

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.
