The Heil PR 77D Microphones are professional-quality dynamic mics for use in commercial broadcast, recording, podcasts—and any application that requires a smooth flat response over a wide frequency range, excellent transient response, great speech articulation and low IMD. These microphones are also great in Amateur Radio applications.
Heil PR 77D Microphones achieve their exceptional performance with a large 1 in., low-mass voice coil encompassed by a powerful magnet structure using a mixture of neodymium, iron, and boron. Additionally, 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.
Heil Sound PR 77D details:
* Element Type: Dynamic
* Output Connection: 3 pin XLR
* Frequency Response: 60 Hz to 18 kHz (music-no filter); 120 Hz to 18 kHz (voice-filter on)
* Polar Pattern: Cardioid
* Impedance: 600 ohms nominal
* Weight: 24.5 oz.
* Max Sound Pressure Level (SPL): 146 dB
* Output Level: -51 dB at 1 kHz
* Rear Rejection: 40 dB at 180 degrees off axis (behind the mic)
Heil PR 77D microphones feature a 2-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 18 kHz is present. They're designed to be used exclusively with booms, bases, or desk stands with the standard 5/8 – 27 microphone stand threads. A CC-1 XLR cable is required to interface with Amateur Radio rigs.
