Heil Sound PR77D Cardioid Dynamic Microphone User Manual

Heil Sound PR77D Cardioid Dynamic Microphone

DESCRIPTION

The Heil PR 77 D is a professional quality dynamic microphone for use in commercial broadcasts, recordings, podcasts, and any application that requires a smooth flat response over a wide frequency range,  excellent transient response, and great speech articulation.

The PR 77 D features a large 1-inch diameter dynamic side-address element. Special attention has been paid to the phasing plug assembly to exhibit exceptional rear rejection. 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 D features a two-position switch allowing the selection of the best characteristics for voice or music. The voice position rolls the audio off at 120 Hz at -6 dB per octave while the music selection removes the filter and the entire audio spectrum of 60 Hz to 16 kHz is present.
