Description

The Heil Sound PR40 is a full-range dynamic microphone designed with the ability to reproduce frequencies as low as 28Hz, ideal for live sound, recording, and broadcast applications. The unique, copper-wound voice coil uses a mixed metallic magnet structure that creates a magnetic field 10 times stronger than most mics. Coupled with a large 1-1/2", low-mass, quilted aluminum diaphragm, this makes for tremendous low-frequency response and low distortion throughout the PR40 mic's wide frequency range. A unique dual pop screen design ensures that breath blasts never hit the diaphragm directly.
