[. . . ] Pattern control is so consistent that the frequency response is nearly independent of angular location of the sound source, creating virtually no off-axis coloration, yet providing greatest possible rejection of unwanted sounds. An integral blast and wind filter covers each acoustic opening on the RE20. In recording sessions or on stage, singers can "close talk" the microphone, singing with their lips almost touching the grille screen with no worry of "P-pops" or excessive sibilance. [. . . ] In recording sessions or on stage, singers can "close talk" the microphone, singing with their lips almost touching the grille screen with no worry of "P-pops" or excessive sibilance. Part of the filter also shock mounts the internal microphone element, reducing the transfer of vibrations from external sources. The exceptional performance of the RE20 is achieved by using a large Acoustalloy diaphragm in combination with an exceptionally low-mass aluminum voice coil. Using this diaphragm assembly, the RE20 is capable of reproducing extremely high sound pressure levels with no fear of the overload and distortion often experienced with phantompowered condensers. The RE20 will also continue to function flawlessly in high humidity and elevated temperatures that would seriously degrade competitive condenser microphones. A massive steel housing and effective hum-bucking coil assure the RE20's resistance to magnetically induced hum and noise. This means the RE20 can be used successfully in situations where other microphones would experience unacceptable Technical Specifications: Generating Element: Dynamic Frequency Response: 45 - 18, 000 Hz Polar Pattern: Cardioid Impedance: 150 ohms balanced Sensitivity, Open Circuit 1. 5 mV/pascal = 1 kHz Voltage: Power Level, 1 kHz (0 dB = 1 mV/Pascal): Hum Pickup Level, typical (60 Hz/ 1 millioersted field): -57 dB -130 dBm Polarity: Pin 2 will be positive referenced to Pin 3 with positive pressure on diaphragm Case Material: Steel Dimensions, Length: 216. 7 mm (8. 53 in. ) Widest Diameter: 54. 4 mm (2. 14 in. ) Body Diameter: 49. 2 mm (1. 94 in. ) Finish: Fawn Beige Net Weight: 737 g (1 lb, 10 oz) Shipping Weight: 1, 474 g (3 lb, 4 oz) Accessories Furnished: 81715 stand clamp Optional Accessories: 309A shock-mounted stand adapter for use with floor stand or recording boom levels of hum and buzz.
