Heil Sound introduces PR 22 hand-held dynamic microphone
Heil Sound has introduced the PR 22 dynamic microphone. Incorporating a completely new dynamic microphone technology, the new model provides a wide frequency range, low handling noise and the ability to handle more than 140dB SPL, making it virtually immune to overload conditions. The mic made its debut with Shelby Lynne on “The Tonight Show with Jay Leno” and was also featured on Gnarls Barkley’s performance on “Saturday Night Live.”
The wide frequency response (50Hz-18kHz) of the PR 22 posed challenges for Heil Sound engineers; conventional remedies to handling noise is to limit the usable bandwidth, hindering frequency response, which was not acceptable. “My goal was to develop an internal suspension system that would eliminate the low frequency handling noise, but not sacrifice sound quality,” Bob Heil said. “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.”
The PR 22 features an outstanding linear cardioid pattern with up to -40dB of rear rejection. Exceptional performance is achieved by using the combination of a large, 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 grille screens (black, silver and gold).
