dj gear. ~ Crown CM30 Crown CM30 Description: The Crown CM-30 is a professional quality, supercardioid condenser microphone designed for inconspicuous miking of a choir, orchestra or stage. ~ The mic cable connects to the electronics/faceplate which fits a standard electrical outlet box. ~ The CM-30 can also hang over conference tables or discussion groups for inconspicuous isolated miking. ~ Because of its supercardioid pickup pattern, the CM-30 rejects background noise and room reverberation, and improves gain-before-feedback more than a cardioid microphone. ~ The CM-30 has a smooth, wide-range frequency response for natural reproduction of the singing voice, organ or other musical instruments. ~ Extreme low frequencies are filtered out to reduce pickup of room rumble. ~ The microphone output is balanced, low impedance. ~ It is protected against static and radio frequency interference. ~ A built-in removable hanger allows easy position adjustment by bending the lower portion of the hanger. ~ The CM-30 requires 12-48V phantom power. ~ The CM-30 is black; the CM-30W is white. ~ Crown CM30 Specifications: Type: Unidirectional condenser. ~ Transducer: Electret condenser. ~ Frequency Response (typical): 40 Hz to 20, 000 Hz. ~ See Fig. ~ 1. ~ Polar Pattern: Supercardioid (see Fig. ~ 2). ~ Impedance: 150 ohms, balanced. ~ Recommended minimum load impedance 1000 ohms. ~ Open Circuit Sensitivity: 10 mV/Pa* (-40 dB re 1 volt/Pa). ~ Power Sensitivity: -37.5 dB re 1 mW/Pa. ~ Equivalent Noise Level: 28 dB SPL typical (0 dB = 0.0002 dyne/cm2), A-weighted. ~ S/N Ratio: 66 dB at 94 dB SPL. ~ Maximum Sound Pressure Level: 120 dB SPL produces 3% THD. ~ Input Connectors: Screw terminals. ~ Output Connectors: Screw terminals. ~ Operating Voltage: Phantom power, 12 to 48 volts DC, positive voltage on pins 2 and 3 with respect to pin 1 of output terminal. ~ Current drain: 4.5 milliamperes. ~ Materials: Brass housing, steel faceplate. ~ Finish: Black (CM-30) or white (CM-30W) microphone, white faceplate. ~ Weight (microphone and cable): 4 ounces (113 grams). ~ Weight (microphone, cable and circuit): 7.5 ounces (212 grams). ~ Cable: Black (CM-30) or white (CM-30W), 30-ft (9.15-m) 2-conductor shielded 0.1-in. ~ (0.254-cm) diameter cable from microphone to electronics; none supplied for electronics output. ~ Use 2-conductor shielded microphone cable. ~ Dimensions: See Fig. ~ 3 on reverse side. ~ Included Accessories: WS-5 windscreen (black or white). ~ Optional Accessories: Crown PH-1A phantom power supply (1 channel, battery or AC adaptor powered), Crown PH-4B phantom power supply (4 channels, AC powered). ~ *1 pascal = 10 dynes/cm2 = 10 microbars = 94 dB SPL. ~ Get your Crown CM30 today! lighting; dj gear; drum sticks; orchesta percussion; electric drums; acoustic drums; percussion; drums; midi; sound modules; groove stations; arrangers; portable keyboards; digital pianos; workstations; synths; electric bass; bass; amps; acoustic guitar; electric guitar; musical instruments;
