The black body Heil Sound PR 77D is a large-diaphragm dynamic microphone designed to provide focused directionality, full-range frequency response, and a vintage appearance for use on vocals and instruments in podcasting, radio, 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.
With a high maximum SPL of 146 dB, it can handle a range of sources from vocals and horns to close-miked drums and guitar cabinets. It offers a 40 Hz to 18 kHz frequency response with a selectable high-pass filter at 80 Hz. The integrated microphone mount allows you to attach it directly to a mic stand without the use of an additional clip or shockmount. The PR 77's standard XLR 3-pin output ensures compatibility with most microphone preamps.
