The Heil PR 77D is a professional quality dynamic microphone for use in commercial broadcast, podcasting, and studio or home recording. 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.
The PR 77D is designed to be used exclusively with booms or bases, and has standard 5/8” – 27 microphone stand threads.
The Heil Sound PL2T Topless mount is a unique and versatile boom that utilizes a system of perfectly balanced internal springs to provide perfect balance and silent, effortless adjustment of its position. The PL2T easily handles microphones weighing up to 3.5 lb. (1.6 kg), and it makes for a professional-looking installation without adding to the clutter in front of you. The Heil PL-2T features a hollow channel that the microphone cable can be fed through and provides the perfect cable maintenance. The unique Topless design of the PL2T allows you to remove the top and back cover plates, so you can thread the microphone cable along the spine of the mount. Once the cable is in place, you snap the cover plates back in place, for a clean installation with no visible wiring.
The PL2T includes a C-clamp that allows for mounting on tables up to 1.5 inches thick
The PL2T is shipped with a standard "C" clamp mount that will accept an 1.5" thick table. An optional flush mount is available which screws to the top of a table or desk surface.
For mounting of your Heil Microphone, the PL2T accepts all of the Heil (industry standard) 5/8" - 27 threaded mic clips or shock mounts. The chrome threaded stem can be locked into the optimum mounting position, depending upon the exact type of microphone and/or shock mount
