User manual ELECTRO-VOICE RE20 EDS

[. . . ] RE20 Variable-D® Dynamic Cardioid Microphone Key Features: · · · · · · Favorite of broadcast show hosts and voiceover studios Ideal for instrument recording, especially kick drums and acoustic guitars Studio condenser response yet no powering required and immune to overloading Large Acoustalloy diaphragm and low-mass aluminum voice coil Dual-ported, continuously Variable-D® with minimal proximity effect Steel case and hum-bucking coil provide exceptional magnetic shielding General Description: The Electro-Voice RE20 is a professional-quality dynamic cardioid microphone created specially for recording, broadcast and sound-reinforcement applications requiring essentially flat response over a very wide frequency range. [. . . ] 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. By exploiting the strength of its steel housing and employing a mechanical nesting concept, EV designers have created an exceptionally rugged microphone with superior handling noise rejection ideally suited for professional uses. Frequency Response: Wiring Diagram: General Description (cont'): The bass-boosting proximity effect common to most directional microphones when used close to the sound source, is eliminated in the RE20. This is accomplished via the application of the EVexclusive Variable-D® technology. By controlling the effect of microphone proximity, the RE20 can be located very close to sound sources without a loss in clarity or definition making the RE20 ideal for tight vocals and challenging instruments. It can be used inside bass drums, on acoustic guitars, and is found in voice booths and broadcasting studios everywhere. Polar Response: Architects' and Engineers' Specifications: The microphone shall be a cardioid type with integral blast filter protecting all acoustic openings. The blast filter shall also serve as a shock mount for the internal microphone element. The microphone shall have a wide-range uniform frequency response from 4518, 000 Hz. An integral passive network shall be provided so that when the filter switch is in the "on" position, low-frequency response shall tilt down 4. 5 dB from 400-100 Hz.
