Description
The PR 22 gives touring engineers and studio hands alike a dynamic mic that finally moves past decades-old cardioid designs. Heil built it around a large 1-1/8″ low-mass diaphragm paired with a neodymium/iron/boron magnet structure — one of the strongest magnet assemblies in its class — to deliver a genuinely linear cardioid pickup pattern with up to 40dB of rear rejection. On a busy stage that translates to a mic that stays focused on the singer or source and ignores wedges, drum bleed, and off-axis noise.
What sets the PR 22 apart from typical ball-style vocal mics is how it handles low end. Most dynamic vocal mics simply roll off response below 125Hz to mask handling noise, sacrificing warmth and body in the process. Heil instead developed the ISO BAND suspension — a Sorbothane rubber isolation system — so the PR 22 can keep its full 50Hz–18kHz response without picking up thumps and rumble from hand or stand movement. The payoff is smooth, hype-free articulation through the upper mids that makes vocals sit forward without harshness, plus enough dynamic headroom for close-mic’d snare or guitar cabs.
SPL handling is rated to nearly 150dB, so screaming leads, cranked amps, and hot brass are all within its comfort zone — no distortion, no compression of the transient. It’s a mic that scales from a rider-friendly vocal channel to a workhorse instrument mic without missing a beat.
