Bosch Audio RE20 Dynamic Cardioid Microphone

Product Description

The BOSCH AUDIO RE20 is a large-element dynamic cardioid microphone built around the Variable-D design, which minimizes proximity effect across the pickup pattern. Unlike conventional dynamic microphones that exhibit significant bass boost as a sound source moves closer, the RE20 maintains consistent low-frequency response at varying distances. This makes it a reliable choice for broadcast, voiceover, podcasting, and live sound applications where consistent tonal character is required. The RE20 is installed and used by broadcast engineers, audio technicians, and studio professionals working in demanding recording and live environments.

The RE20 is widely used in professional broadcast booths, radio studios, recording studios, and live stage applications. Its internal pop filter and consistent cardioid polar pattern make it well suited for close-miking vocals, instruments, and broadcast commentary. The microphone is designed for use with standard XLR-equipped preamps and mixing consoles and does not require phantom power to operate.

Designed as a professional-grade dynamic cardioid microphone compatible with standard balanced XLR microphone inputs on preamps, mixing consoles, and audio interfaces.

Installation Notes

The RE20 is installed by audio engineers and broadcast technicians using a standard microphone stand or broadcast boom arm with a compatible XLR cable. Ensure the connected preamp or console channel is muted or gain is set to minimum before connecting or disconnecting the microphone. No phantom power should be required, but verify preamp settings before use. Follow applicable broadcast facility or venue wiring standards when integrating into a permanent installation.
