Overview of Heil PR 77D Large-Diaphragm Dynamic Microphone (Black Body)
The Heil PR 77D is a professional quality dynamic microphone for use in amateur radio and pro applications. It is perfect for any application that requires a smooth, flat response over a wide frequency range, excellent transient response, great speech articulation, and low intermodulation distortion (IMD). The PR 77D achieves its exceptional performance via a large, 1-jnch, low-mass voice coil encompassed by a powerful magnet structure using a mixture of neodymium, iron and boron. 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. Unique to the PR 77D is a two-position switch allowing the user to select optimal response frequency characteristics between Voice and Music applications. The Voice position rolls the audio off at 120 Hz at -6 dB per octave, whereas the Music position removes the filter and uses the entire audio spectrum of 60 Hz to 16 kHz.Music City Canada is an authorized reseller for Heil products.
