Heil Sound Introduces PR 22 Dynamic Microphone

July 02, 2008

Expanding upon the highly successful PR 20, the Heil PR 22 represents completely new dynamic microphone technology, providing wide frequency range, low handling noise and the ability to handle +140 dB SPL for a wide range of professional applications. The new Heil PR 22 microphone is usable in extreme high sound pressure levels and immune to overload conditions making it perfect for live vocal and instrument applications as well as a superb microphone for serious recording studios. The mic made its debut with Shelby Lynne on "The Tonight Show with Jay Leno", and was recently featured on Gnarls Barkley's performance on "Saturday Night Live."

The wide frequency response (50 Hz to 18 kHz) of the PR 22 posed challenges for Heil Sound engineers; conventional remedies to handling noise is to limit the usable bandwidth thus hindering frequency response, which was not acceptable. Bob Heil comments, "My goal was to develop an internal suspension system that would eliminate the low frequency handling noise, but not sacrifice sound quality. Working with a 'suspension' engineer who deals in ceiling fans and motor mounts, we came up with the IsoBand*, a unique internal band of specialized rubber which brings an exciting new dimension to the dynamic vocal microphone."

Since 1982, Heil Sound has been the leading manufacturer of communications microphones and has a paramount understanding of phase coherence. This was applied to the PR 22 to create an outstanding linear cardioid pattern with up to -40 dB of rear rejection. Exceptional performance is achieved by using the ideal combination of materials for the large 1 1/8' diameter low mass diaphragm and a special mixture of neodymium, iron, and boron that gives the PR 22 the strongest magnet structure available. The PR 22 is supplied with a leatherette carrying case, a mic clip and three metal screw-on grill screens (black, silver and gold).
