The CM33 is an electret condenser pressure gradient transducer with a cardioid
polar pattern. It features a 16mm diameter 3 micron gold plated Mylar diaphragm.
The CM33 has a high sensitivity and broad frequency range making them excellent
for critical recording, as well as sound reinforcement applications. The CM33
exhibit a wide dynamic range and frequency response for accurate sound reproduction
across the audio spectrum, Balanced transformerless output for increased immunity
to noise over long cable runs, included foam windscreen avoid wind noise. In
each packaging, two factory matched CM33 are included, convenient for stereo
recording applications.
