The CM-H8C microphone has a dual 1" diameter membrane capsule. Altering the potential of the membranes produces three polar patterns - omnidirectional, cardioid and figure 8 which are selectable by a switch located on the microphone body. It provides the user with excellent features including high sensitivity, low noise, wide bandwidth, a large dynamic range and precision sound at very low distortion. An excellent 142 dB SPL makes this microphone ideal for extremely high sound pressure level sound reproduction and recording.
