The Heil PR40 microphone boasts the widest frequency range of any dynamic mic in the Heil PR series. The PR40 incorporates Heil's sage-like understanding of phasing plug placement, along with the use of a very large (1?), low mass diaphragm, and custom magnet metals housed in a specially designed microphone body. The PR40 diaphragm is shock mounted such that it is completely de-coupled from the anodized Champagne matte-finished steel body. In addition to dual mesh screens, each made with different diameter screen apertures, there is an internal breath blast filter on the diaphragm element itself, providing superb response for the human voice across the entire vocal range, without "popping†noises. In fact, the PR40 will provide a flawless, smooth, flat response from 28Hz all the way up to the 18kHz, making this a great microphone for everything from vocals, to bass drums and tom drums, to guitar and bass cabinet micing and more. In short, the PR40 is known by professionals as the "thoroughbred workhorse†of professional sound recording and reinforcement. The PR40 is available in black, black with a gold grill, champagne, gold plate, or chrome plate. It ships with a mic clip and a leatherette carry bag. A windscreen is available to purchase separately.
