New Product Announcement

Heil Sound, Ltd.

(Fairview Heights IL) Heil Sound is pleased to introduce the PR 77D, a large-diaphragm microphone designed to provide focused directionality, full-range response, and a vintage appearance for use in podcast, broadcast, recording, and live stage applications. It features a classic side-address design based upon popular RCA microphones from the ‘50s and ‘60s. Its cardioid polar pattern delivers 40 dB of attenuation 180° off-axis, resulting in a tight pickup area and minimized bleed. The PR 77D is an updated version of the PR 77 from Heil Sound. 

The Heil PR 77D 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.

Standard 5/8” – 27 microphone stand threads allow The PR 77D to be mounted direct to booms or bases. The PR 77D retails for $249.00 USD and is available from authorized Heil Sound dealers.
