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 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.
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 infor-
mation.
