Heil Sound PR 20 Cardioid Dynamic Microphone

The PR 20 is the microphone that introduced most engineers to Heil's large-element dynamic approach. It is a cardioid that handles 145 dB and rejects -30 dB off the back, which makes it a straightforward choice for handheld vocals, snare, toms, and cabinets where a condenser would be fragile or too hot.

The response runs 50 Hz to 18 kHz into a 600 ohm balanced 3-pin XLR at -55 dB output level, so it drops into any console channel without phantom power. The body weighs 14 oz and the package includes a padded zipper carrying case, a windscreen, and a mic clip.
