Heil Sound PR 40 (Black)

The Heil Sound PR 40 Black is a dynamic microphone designed for professional audio applications. This end-fire model features a large 2.9 cm (1-1/8 inch) diaphragm element with a flat, neutral frequency response of 28 Hz to 18 kHz, making it suitable for various recording scenarios, including vocals, drums (especially toms and bass drum), as well as guitar and bass amplifiers. The microphone utilizes a cardioid pattern with four rear vents that effectively reject off-axis sounds and provide precise directional characteristics. Its robust construction includes an internal shock mount made of Sorbothane material, which isolates the microphone element from handling noise and mechanical vibrations. The PR 40 can handle high sound pressure levels up to 148 dB while maintaining a wide dynamic range thanks to its lightweight diaphragm and strong NdFeB magnet structure. Technical specifications include an impedance of 600 ohms, a balanced output via a 3-pin XLR connector, and a sensitivity of -53.9 dB at 1 kHz. The microphone offers a rear rejection of -40 dB at 180 degrees off-axis, ensuring minimal pickup from unwanted directions. Weighing 383 grams and featuring a black finish, this professional microphone comes with a cast metal microphone clip and a protective case, making it a reliable choice for studio recordings and live sound reinforcement.
