The Heil PR-40 is the completely new technology dynamic microphone designed for a wide range of professional applications such as recording, live sound, and commercial broadcasting. Produce the widest range of frequencies available in a dynamic microphone, the PR-40 exceeds most condenser microphones, and able to withstand huge amounts of SPL. At the same time, keeps the 25-year tradition of Heil Sound of superbly natural voice articulation.


Since 1982, Heil Sound has been the leading manufacturer of communications microphones and has a paramount understanding of phasing. When properly applied, this knowledge creates outstanding cardioid patterns with unbelievable rear rejection that removes unwanted sounds that try to enter from the off axis rear. The pattern control of the Heil PR-40 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 PR-40 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 large diameter dynamic element is mounted in a unique shock mount atop a non-resonant fixture, decoupling the element from the massive steel body. This body and the internal hum bucking coil removes any worry of using the PR-40 near monitor screens or noisy lighting fixtures and controls. The new technology of the Heil PR-40 has redefined the dynamic microphone with superior wide frequency response, the lowest presence of noise in the industry, flawless design, and elite quality expected by an innovator and leader in the field. Welcome to the new standard.
