Heil Sound PR77D - Black Body Deco Series Dynamic Mic with PR40 Element in Black
The Heil PR 77D is a professional quality dynamic microphone for use in amateur radio and pro applications. 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-jnch, 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.

Unique to the PR 77D is a two-position switch allowing the user to select optimal response frequency characteristics between Voice and Music applications. The Voice position rolls the audio off at 120 Hz at -6 dB per octave, whereas the Music position removes the filter and uses the entire audio spectrum of 60 Hz to 16 kHz.
