Heil Sound PR77D Large-Diaphragm Dynamic Microphone (Black Body)

Vintage Broadcast Dynamic Microphone for Voice and Instruments

The Heil Sound PR77D Deco Series microphone is a large-diaphragm dynamic microphone built for professional broadcast, podcasting, recording, and live sound applications. Designed with a classic side-address body inspired by mid-century broadcast microphones, it delivers focused pickup, high output, and controlled frequency response for clear vocals and detailed instrument capture.

Cardioid Pickup Pattern for Controlled Sound Capture

The PR77D uses a cardioid polar pattern that concentrates pickup directly in front of the microphone while rejecting sound from the rear and sides. With strong off-axis rejection, it minimizes room noise, feedback, and bleed, making it well suited for podcast studios, radio booths, live stages, and untreated recording environments.

Wide Frequency Response with Selectable Low Cut Filtering

Covering a frequency range from 40 Hz to 18 kHz, the PR77D captures low-end warmth while maintaining vocal clarity and articulation. A built-in 80 Hz high-pass filter allows users to reduce rumble, plosives, and proximity buildup when recording speech or close-miked sources, giving greater control at the source.

High SPL Handling for Demanding Audio Sources

With the ability to handle very high sound pressure levels, the PR77D performs equally well on loud instruments such as guitar cabinets, brass, and drums, as well as spoken voice and singing. The dynamic capsule remains stable under heavy input, preventing distortion while preserving tonal balance.

Classic Side Address Design with Integrated Mounting

The Deco Series housing delivers a timeless broadcast look while remaining practical for modern workflows. The integrated microphone mount allows direct attachment to standard mic stands or boom arms without requiring a separate clip or shockmount, simplifying setup and reducing clutter in studio or stage environments.

Professional Connectivity for Studio and Live Use

A standard XLR 3-pin output ensures compatibility with a wide range of microphone preamps, audio interfaces, mixers, and broadcast consoles. As a dynamic microphone, the PR77D does not require phantom power, making it easy to integrate into both portable and fixed audio systems.
