MICROPHONE
he Crown® CM-200A is a cardioid condenser
microphone for professional vocal and instru-
T
mental use. It offers studio-quality sound, yet
is rugged enough to withstand hard professional
use in the fi eld. Its outstanding performance is
complemented with handsome styling and a comfortable balance.
The sound of the CM-200A is smooth and nonharsh – yet very articulate – with a wider frequency
range than standard vocal microphones. When
used up-close, its proximity effect boosts the lowfrequency response for a warm, robust sound. An
upper-midrange “presence peak” adds intelligibility.
The cardioid polar pattern increases gain-beforefeedback, rejects unwanted background noise, and
discriminates against sounds approaching the rear
of the microphone.
A built-in multi-stage pop fi lter effectively suppresses explosive breath sounds. Handling noise
is extremely low. The unit can withstand repeated
drops and abuse, as well as extremely loud sound
pressure levels without distortion.
The output of the microphone is balanced, low
impedance, which allows long cable runs without
hum pickup or high-frequency loss. The unit can
be phantom powered from the console or other
remote power supply.
Included with the CM-200A is a convenient carrying pouch, an adjustable microphone stand adapter
for mounting the unit to any microphone stand,
and a foam windscreen to further reduce breath
popping and wind noise.
Operating Instructions
Using a 2-conductor shielded microphone cable
(not supplied), plug the microphone into a mixer
mic input with 12 to 48 volts phantom powering or
use a remote phantom power supply. Crown makes
a PH-1A phantom power supply (1 channel, battery
or AC-adapter powered). For special applications,
you can make your own battery supply as suggested in Fig. 4.
For maximum gain before feedback, sing close to
the microphone (lips touching the grille) and place
loudspeakers forward of the rear of the microphone (downstage from the performer).

• Cardioid polar pattern reduces feedback and
background noise
• Smooth, articulate sound with up-close bass
boost
