The Heil PR30B represents completely original dynamic microphone technology designed for a wide range of professional applications such as sophisticated recording, live sound, and commercial broadcast. Its smooth, wide frequency range sounds like a ribbon but can withstand large amounts of SPL. Outperforming the tired, 30-year-old technology of the industry, the large diameter of the Heil PR30B's dynamic element produces an outstanding upper mid-range that makes the PR30B an ideal guitar microphone as well as an excellent choice for reproducing the human voice.The pattern control of the Heil PR30B dynamic microphone is outstanding. This exceptional performance is achieved by using the ideal combination of materials for the large low-mass diaphragm and a special mixture of neodymium, iron, and boron that gives the Heil PR30B mic the strongest magnet structure available. These features allow the microphone to achieve magnificent dynamic range. A unique screen system using two different diameter mesh screens and an internal breath blast filter allow the user to talk closely to the microphone with little worry of pops or excessive sibilance. The Heil PR30B's large diameter dynamic element is mounted in a unique sorbothane shock mount atop a non-resonant fixture, decoupling the element from the massive steel body. This body and the internal humbucking coil removes any worry of using the PR 30B near monitor screens or noisy lighting fixtures and controls. The new technology of the Heil PR30B has redefined the dynamic mic with superior wide frequency response, low presence of noise, flawless design, and elite quality expected by an innovator and leader in the field.
