The CM87 is a large-diaphragm, 3-pattern, dual back-plate, fet condenser microphone that features a dual diaphragm capsule with 6-micron diaphragms. It incorporates a Class "A" dual stage fet/discrete transformer coupled amplifier design with high quality through-hole components.
 
It is well suited for a variety of recording applications such as vocals or instruments in any studio or live application.  It can handle extreme sound pressure levels with ease.
The CM87 is built to a very high standard and offers a remarkably full yet well-defined and ultra-clean sound that is perfectly suited to the most demanding radio, dialogue and recording tasks. Its pickup pattern can be configured in omni, cardioid, or Fig-8. 
The CM87 has at least 10db more headroom than the venerable U87 circuit while retaining the same sonic response and reliability.
 
The CM87 excels as an affordable replacement for the expensive U87.
Recently, Sirius Satellite XM in Nashville bought over 2 dozen -CM87 microphones for their On Air Studios. Warner Brothers and Marvel Comics also use CM87 microphones to capsule vocals from voice actors on many animation series.
