® 

 CM-200A is a cardioid condenser 

microphone for professional vocal and instru-
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 com-
fortable balance.

The sound of the CM-200A is smooth and non-
harsh – yet very articulate – with a wider frequency 
range than standard vocal microphones. When 
used up-close, its proximity effect boosts the low-
frequency response for a warm, robust sound. An 
upper-midrange “presence peak” adds intelligibility.

The cardioid polar pattern increases gain-before-
feedback, rejects unwanted background noise, and 
discriminates against sounds approaching the rear 
of the microphone.

A built-in multi-stage pop fi lter effectively sup-
presses 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 carry-
ing 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.

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 sug-
gested 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 micro-
phone (downstage from the performer).
