Heil Sound PR77D – Professional Decco Series Microphone with PR40 Element (Black)


The Heil PR 77D is a professional quality dynamic microphone for use in commercial broadcast, podcasting, and studio or home recording. It is perfect for any application that requires a smooth, flat response over a wide frequency range, excellent transient response, great speech articulation, and low intermodulation distortion (IMD).


The PR 77D achieves its exceptional performance via a large, 1-inch, low-mass voice coil encompassed by a powerful magnet structure using a mixture of neodymium, iron, and boron. Special attention has been paid to the phasing plug assembly to provide exceptional 180-degree, off-axis rear rejection of over -40 dB. Simultaneously, the front pattern allows the user to move about freely in front of the element with no change in response.
