[. . . ] 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. The wide frequency response, coupled with excellent transient response, make the RE20 easily comparable to the finest condenser cardioid microphones and an easily operated "bass tilt down" switch corrects spectrum balance for use in longreach situations or other applications where bass attenuation is needed. [. . . ] 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. With switch in "off" position, microphone shall be essentially "flat" from 80-6, 000 Hz, with a broad 2. 5 dB rise in response from 6, 000-14, 000 Hz, and nominally down 3 dB at 18, 000 Hz. Response below 80 Hz shall be nominally down 3 dB at 45 Hz. Output level shall be -57 dB (0 dB = 1 mW/Pascal). Response at any angular position away from the major axis shall be essentially similar to the response on the major axis, but attenuated uniformly at all frequencies by an amount appropriate to that angular position.
