The Heil PR 40 microphone boasts the widest frequency range of any dynamic mic in the Heil PR series. The PR 40 incorporates Heil’s phasing plug technology, along with the use of a very large (1"), low mass diaphragm, and custom magnet metals housed in a specially designed microphone body.


The PR 40 diaphragm is shock mounted such that it is completely de-coupled from the anodized Champaign 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 PR 40 will provide flawless, smooth, flat response from 28 Hz all the way up to the 18k Hz, making this a great microphone for everything from vocals, to bass drums and tom drums, to guitar and bass cabinet mic’ing and more.

In short, the PR 40 is known by professionals as the “thoroughbred work-horse” of professional sound recording and reinforcement.

With the PR 40 you get an adjustable cast metal microphone holder in a padded
Leatherette bag with molded foam insert.
