The Heil PR40 Kit 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 ‘poppinginch 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 workhorseinch of professional sound recording and reinforcement. This kit includes a PRSM Shock Mount is a flexible support system that helps suppress low-frequency rumble on the microphone line by absorbing and damping vibrations picked up from the studio desk or console. Plus a two-section broadcast arm with internal springs and an integrated XLR cable. It’s ideal for broadcast, voiceover, and podcasts and an extra XLR-XLR cable.
