The Electro-Voice RE50 is a specially shock-isolated, omnidirectional, dynamic microphone. An advancement in shock-mounting techniques, they were designed particularly for hand-held broadcast and sound reinforcement use. All handling noises, clothing noises, and even cord shock have been isolated from the microphone element so that mechanical induced noise is greatly reduced. By use of a high-mass zinc internal acoustic chamber, shock-mounted within the machined aluminum outer casing, the Electro-Voice RE50 offers a degree of isolation unprecedented in an omnidirectional dynamic microphone.
