Carvin CM50 User Manual

GENERAL

The CM50 is Carvin’s entry level vocal mic.
It is designed mainly for vocals, however, it
can easily double for micing guitar amps or
drums (excluding kick drum). Features a con­venient on/off switch for reducing noise and
feedback when not in use. Unidirectional
with a cardioid polar pattern. Built in foam
wind screen for pop, breath, and wind noise
rejection.

Microphone Features:

■ Bright, clean sound. Especially good for

announcing, narration and dialogue, vocal
music, and rhythm pickups

■ Wind and “pop” filter readily removable

for cleaning or replacement

■ Unusually effective cardioid pickup pattern to

minimize background noise and undesirable
effects of studio and location acoustics. Rear
and side rejection uniform to very low fre­quencies and completely symmetrical about
microphone axis

■ Self-contained spherical filter to control

explosive breath sounds (“pop”) and wind
noise in outdoor locations

■ Cartridge shock-mounted for protection and

quiet operation

■ On/Off switch
