dj gear. ~ Crown CM31 Crown CM31 Description: The Crown CM-31 is a professionalquality, supercardioid condenser microphone designed for inconspicuous miking of a choir, orchestra or stage. ~ It can also hang over conference tables or discussion groups for inconspicuous isolated miking. ~ The CM-31 consists of two parts: the microphone with a permanently attached 30-foot (9.15-m) cable and the cylindrical electronics power module. ~ The mic cable connects to the power module, which adapts the microphone for phantom powering and includes a low-cut switch. ~ Cable connection is via miniature 3-pin connectors. ~ The power module output is balanced, low impedance. ~ It is protected against static and radio-frequency interference. ~ The CM-31 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 has a built-in removable hanger which allows easy position adjustment. ~ The CM-31 microphone and cable are black; the CM-31W microphone and cable are white. ~ Crown CM31 Specifications: Type: Unidirectional condenser. ~ Transducer: Electret condenser. ~ Frequency Response (typical): 40 Hz to 20, 000 Hz Polar Pattern: Supercardioid 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 =.0002 dyne/cm2), A-weighted. ~ S/N Ratio: 66 dB at 94 dB SPL. ~ Maximum Sound Pressure Level: 120 dB SPL produces 3% THD. ~ Mic-Cable Connector: TA3F (mini XLR-type). ~ Power Module Connector (input): TB3M (mini XLRtype). ~ Power Module Connector (output): 3-pin male XLRtype. ~ Power Module Switch: Flat/low-cut. ~ 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: Brass housing, steel power module housing. ~ Finish: Black (CM-31) or white (CM-31W). ~ Weight (microphone and cable): 4 ounces (113 grams). ~ Weight (microphone, cable and power module): 9.5 ounces (269 grams). ~ Cable: Black (CM-31) or white (CM-31W), 30' (9.15-m) 2-conductor shielded 0.1" (.254-cm) diameter cable from microphone to electronics; none supplied for electronics output. ~ Use 2-conductor shielded microphone cable. ~ Dimensions: See Fig. ~ 5 on reverse side. ~ Included Accessories: WS5 black foam windscreen for CM-31, WS5W white foam windscreen for CM-31W. ~ 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 CM31 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;
