Professional Dynamic Cardioid Studio Microphone
From the Professional division of Heil Sound, Ltd., we present the PR-20, a professional quality dynamic cardioid microphone designed for commercial broadcast, recording and live sound reinforcement applications which require a smooth flat response over a wide frequency response. The PRO-20 has a comparable sound to the finest condenser microphone because of it's wide frequency response, excellent transient response and low IMD. Following a 20 year Heil tradition, the new PRO-20 exhibits gorgeous natural speech articulation without having to apply heavy electronic equalization. Truly one of the most natural and pleasant sounding dynamic microphones, ever.
The Heil engineers have created a very rugged microphone with superior low handling noise by mounting the very wide frequency response dynamic element into a special sorbothane shock mount system. This low handling noise and exceptional lack of bass-boosting proximity effect makes it ideal for professional uses.
The PR20 achieves it's exceptional performance by using a special magnet structure and a large aluminum 1 1/8" low mass voice coil assembly. Special attention has been paid to the phasing plug assembly with equally placed ports that sense audio from behind the source entering them out of phase thus producing a very linear cardioid pattern and reduces the proximity effect while achieving the extreme articulation across it's smooth 50 - 18,000 Hz. frequency response. The new Heil 'PROLINE' element is usable in extreme high sound pressure levels and is immune to overload conditions as a condenser usually will be. It produces a beautifully smooth audio response without the inconvenience of phantom or outside d.c. powering.
The cardiod pattern offers the greatest rejection at 180 degrees off axis which is directly behind the microphone and creates virtually no off-axis coloration while providing the greatest possible rejection of unwanted audio.
The Heil PR-20 professional microphone is delivered to you in a classy leatherette carrying bag including the mic clip and acoustical foam windscreen.
