The Heil Sound PR 40 Black/Gold is a dynamic microphone featuring a black housing and gold-colored grille cover. This dynamic large-diaphragm microphone offers a flat, neutral frequency response from 28 Hz to 18 kHz, making it suitable for various professional audio applications. With its cardioid polar pattern and four rear vents for suppressing background noise, the microphone provides excellent rear rejection of -40 dB at 180 degrees off-axis. The internal vibration dampening system made of Sorbothane material effectively isolates the microphone element from handling noise and mechanical vibrations. Equipped with a lightweight 28.6 mm end-fire dynamic element and a strong NdFeB magnet structure, the PR 40 can handle maximum sound pressure levels of up to 148 dB while maintaining a wide dynamic range. The microphone exhibits a sensitivity of -53.9 dB at 1 kHz with a 600-ohm balanced impedance. The 3-pin XLR connector ensures reliable professional audio connections. Weighing 383 grams, the microphone is made from durable materials and includes a die-cast metal microphone clip for secure mounting. The PR 40 Black/Gold is particularly well-suited for vocal recordings, drum applications including tom-toms and bass drums, as well as for recording guitar and bass amplifiers in live performances and studio recording environments. The microphone comes complete with a protective carrying case and mounting accessories.
