The Heil PR 35 is a dynamic microphone designed for vocal live sound reinforcement and recording. The PR 35 has a characteristic smooth frequency response, providing a warm and lush presence to vocals of all kinds. The dynamic element of the PR 35 is suspended in a floating mount, allowing air to move around the element and preserving articulate sound when the mic is cupped. Like all Heil mics, the PR 35 has excellent rear noise rejection, even in high stage volume situations. The PR 35 features a low-end roll-off switch for vocalists looking to tailor their response. Ready for stage use, the PR 35 has a durable rubberized exterior coating for added protection and grip. The PR 35 is available in black, chrome, gold, or switched (on/off) black versions.
