The Electro-Voice RE20 is an iconic broadcast-grade dynamic microphone renowned for its exceptional consistency and smooth, natural sound reproduction, making it a standard in radio, television, and professional voice recording. Its defining technical feature is the Variable-D (variable distance) polar pattern, a patented design that maintains a consistent bass response regardless of the announcer's proximity to the microphone. This eliminates the exaggerated low-end boost, or "proximity effect," common in other directional microphones, allowing broadcasters and voice-over artists to work close to the mic without their voice becoming boomy or muddy, which is critical for maintaining clarity and intelligibility over the air.

Encased in a robust, all-metal housing with an internal, highly effective pneumatic shock mount, the RE20 is engineered to reject mechanical noise and vibrations from the stand or handling. The grille design incorporates a built-in pop filter to minimize plosive sounds, while the tailored frequency response provides a slight presence rise that enhances vocal articulation without sounding harsh or sibilant. Its cardioid polar pattern offers excellent off-axis rejection, helping to isolate the voice from ambient studio noise, air conditioning, or other unwanted sounds. The balanced, low-impedance output ensures clean, noise-free signal transmission, even over long cable runs in complex studio setups.

Valued for its durability and timeless sound, the RE20 has earned a reputation as a workhorse microphone that delivers reliable, broadcast-ready audio day after day. Its ability to handle high sound pressure levels without distortion also makes it suitable for close-miking brass instruments and kick drums in studio recording. For producers, engineers, and on-air talent, this microphone provides a trusted tool that captures the full character of the human voice with accuracy and warmth, contributing to a professional, polished audio presentation that has defined broadcast sound for decades.
