Crown CM-700 Cardioid Condenser Microphone
The CM-700 is a cardioid condenser microphone for pro or semi-pro recording and high-quality sound reinforcement. Rugged enough for the road, the CM-700 is well suited for acoustic instruments, drum overheads and studio vocals. It works equally well for popular music (multimiking) or classical music (stereo and spot miking). Small and inconspicuous, the CM-700 is also a good choice for miking a lectern.
The CM-700 has a very smooth, wide-range frequency response which gives it a natural sound. It preserves the delicate timbre of acoustic instruments, yet it can reproduce all the power of a pipe organ. The off-axis response is also smooth, so any leakage picked up has little coloration. Because of its cardioid pickup pattern, the CM-700 reduces background noise, room reverb and feedback. The cardioid pattern is uniform with frequency. Self-noise is very low, permitting clean, noisefree recordings. The mic can handle extremely loud sounds without distortion. It is protected against static and RFI. The output is balanced, low impedance, which allows long cable runs without hum pickup or high-frequency loss. Powering is by 12-48V phantom power.
Several audiophile touches enhance the mic’s pristine sound quality: an ultralight diaphragm, humbucking transformer, polycarbonate capacitors and a gold-plated 3-pin connector. The CM-700 has a bass-tilt switch with three positions: flat, low-cut and rolloff. An included 2-stage foam pop filter softens breath pops and a foam windscreen reduces wind noise
outdoors.
