Heil PR 77 Proline Broadcast Mic

The Heil PR 77 Deco Series Mic is a professional quality dynamic microphone for use in commercial broadcast, recording, podcasts and any application that requires a smooth flat response over a wide frequency range, excellent transient response, great speech articulation and low IMD.

The PR 77 achieves its exceptional performance with a large 1 inch low mass voice coil encompassed by a powerful magnet structure using the mixture of neodymium, iron and boron. Special attention has been paid to the phasing plug assembly. The entire bottom of the element allows unwanted audio from the rear and sides to enter from all 360 degrees resulting in the rear rejection of over -40 dB. Little to nothing is heard from the rear while the front pattern allows the user to move about freely in front of the large diameter with no change in response.

The Heil PR 77 features a two position switch allowing the selection of the best characteristics for voice or music. The voice position rolls the audio off at 80 Hz at -6 dB per octave while the music selection removes the filter and the entire audio spectrum of 40 Hz to 18 kHz is present. The angle of the microphone may be adjusted. Requires appropriate CC-1 cable (sold separately) and has standard 5/8 inch 27 thread for a base or boom.
