Here is the Springfield Music Gearbox Review of the Heil PR22!
The Heil PR 22 represents completely new dynamic microphone technology designed for a wide range of professional applications such as live sound, commercial broadcast, and sophisticated recording. Never before has such quality been built into a dynamic vocal microphone. With its wide frequency range, outstandingly low handling noise and ability to handle +140dB SPL, the PR 22 outperforms the tired, 30+ year old industry technology.
The end result is a microphone that can answer the call for any application. For example, the gorgeous articulation in the upper mid- range makes the PR 22 the best live vocal microphone, while its outstanding frequency response and superb dynamic range suit it perfectly for use with a snare drum or guitar instrumentation.
