CARVIN CM67 User manual

GENERAL
The Carvin CM67 is a dynamic unidirectional
microphone built to provide wide range repro-
duction of music and voice. It features an
exceptionally uniform and effective unidirec-
tional pickup pattern. The performance char-
acteristics and unique construction make it
ideal for in-studio or concert use where a
sound technician controls the mixing. This
microphone has exceptional feedback control
and will take high input signals from drums
and instrument amps without overloading.
The overall sound is bright and clean with
excellent bass without boominess. An excel-
lent choice for instrumentation.
Microphone Features:
The CM67 is also designed for high end stu-
dio recording and broadcast applications.
■ Cartridge shock-mounted for protection and
quiet operation
■ Bright clean sound. Especially effective for
announcing, narration and dialogue, vocal
music, and rhythm pickups.
■ 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 fre-
quencies and completely symmetrical about
microphone axis
■ Versatility - designed for use in the hand or on
a stand - for use indoors or outdoors
■ Microphone supplied with adjustable swivel
adapter - permits tilting through 90° from
vertical to horizontal
■ Supplied with a lockable off/on switch
