The RE520 is a premium-grade, high-performance supercardioid condenser vocal microphone. Designed to reveal the exceptional detail and vivid clarity synonymous with condenser elements, it elegantly delivers the lyrical finesse required for expressive vocal performances while controlling off-axis sound from nearby sources.

The sonic signature is detailed, full, and vivid, with a warm and clear low end, a natural and present midrange, and an open, crisp, and detailed high end.

The supercardioid pattern provides excellent acoustic isolation. Maximum feedback rejection occurs when a stage monitor position is at either 225° or 125° off-axis to the element. This pattern also allows for a cleaner mix due to its rejection of off-axis sound.

The multi-stage pop filter consists of two layers of dense foam separated by air, which attenuates wind velocity caused by breath and windblasts.

The high-pass filter has two positions. The flat position delivers the full frequency bandpass of the capsule. The high-pass position attenuates frequencies below 150 Hz.

The internal shock mount isolates the microphone element from vibration and guards against handling noise.
