User manual CROWN CM-700 DATASHEET

[. . . ] 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. [. . . ] Power sensitivity: ­52 dB re 1 mW/Pa*. Equivalent noise level (self-noise): 21 dB SPL typical A-weighted (0 dB=. 0002 dyne/cm2). Maximum SPL for 3% THD: 151 dB with 48V phantom, 142 dB with 12V phantom. Polarity: Positive pressure on the diaphragm produces a positive voltage on pin 2 with respect to pin 3 of the output connector. Output connector: 3-pin male XLR-type connector. Operating voltage: Phantom power, 12 to 48 volts DC, positive voltage on pins 2 and 3 with respect to pin 1 of output connector. Materials: Rugged steel housing and steel mesh grille. Included accessories: Carrying pouch, WS-12 foam pop filter, WS-11 foam windscreen, ASA-4 swivel mount. Operating temperature range: ­20° to +50° C, or -4° to +122° F. Optional accessories: Crown PH-1A phantom power supply (1 channel, battery or AC powered), CM-SM isolation shock mount. *1 pascal = 10 microbars = 10 dynes/cm2 = 94 dB SPL.

LOW-CUT ( ): For removing rumble from air conditioning and trucks and to reduce breath pops in vocal recordings. ROLLOFF ( ): For lectern use or close miking.
