Heil Sound PR37 Super-Cardioid Handheld Dynamic Vocal Microphone

Heil Sound PR37: An Ultra-Clear Handheld for Vocals

The Heil Sound PR37 is a handheld super-cardioid dynamic microphone designed for live sound reinforcement and recording with the vocalist in mind. As the next step in Heil's family of vocal microphones, it delivers an ultra-clear, transparent sound that cuts brilliantly through any mix. A large-diameter element, a stable internal mount, and a rugged metal body make it a true stage workhorse. For the singer who wants clarity and durability in one microphone, it is a modern flagship vocal tool.

Voiced to Cut Through Any Mix

Heil tuned the PR37 with smooth low mids and an enhanced upper-mid presence that lets a voice shine effortlessly. That upper-mid lift is the range where a vocal gains intelligibility and cuts through guitars, keys, and a full band. The result is a transparent, articulate sound that keeps the lead vocal audible without harsh EQ boosts. Live vocalists in dense mixes gain presence that keeps them out front all night.

A Large Element for Detail

At the core of the PR37 is a large-diameter dynamic element that captures more nuance than a typical handheld. In a dynamic microphone, sound pressure drives a diaphragm and coil through a magnetic field, needing no phantom power and tolerating high volume. The larger capsule brings a fuller, more detailed vocal while keeping the ruggedness and feedback resistance of a dynamic. Singers hear a richer, more natural rendering of their voice.

Stable Mount Tames Handling Noise

The large element of the PR37 is housed in a stable mounting system designed to reduce handling noise. When a singer grips and moves a handheld microphone, mechanical vibration would otherwise reach the capsule as distracting low-frequency thumps. By securing and isolating the element, the mount keeps the vocal channel clean during active performance. Performers who work the mic hard keep a quiet, professional signal.

Superior Rear Rejection

A super-cardioid polar pattern gives the PR37 excellent rear noise rejection, turning away as much as 40 dB from behind. That isolation is especially valuable in live applications with high stage volume, where monitors and instruments crowd the space. Rejecting off-axis sound gives the engineer more gain before feedback and a tighter overall mix. On a loud stage, the vocal stays clear while spill stays out of the channel.

A Rugged Metal Workhorse

The PR37 is built around a rugged metal body engineered for durable, reliable protection. That all-metal construction makes it the quintessential workhorse microphone for the knocks and drops of nightly live use. A tough handheld like this keeps performing where flimsier microphones would fail, protecting the investment over years of gigs. Touring vocalists gain a dependable tool that still delivers Heil-quality sound.

Complete and Stage-Ready

Each PR37 arrives with a padded zipper carrying case, a windscreen, and a mic clip, so it is ready to work out of the box. The three-pin XLR output carries a balanced, low-impedance signal that resists hum over long cable runs. Because it is a passive dynamic, no phantom power, batteries, or drivers are required. Plug it into any mixer or interface and the microphone is ready to perform.
