Heil Sound PR 77DP Large-Diaphragm Dynamic Microphone (Purple Body)

The purple body Heil Sound PR 77DP 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.

This microphone is part of the Fotohaus Klinger Virtual Mic Locker, an online tool to help our valued customers determine the sonic differences between popular microphones for podcasting and voice over work. Each microphone was recorded using a Grace Design M103 preamp into a Presonus Quantum 2626 interface.
