The Heil PR30 Proline Broadcast Mic is 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 PR-30 has a comparable sound to the finest condenser microphone because of it's wide frequency response, excellent transient response and low IMD.

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 PR-30 comes with a Heil small mount to facilitate connection to a 5/8 inch 27 standard threaded mic mount.

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.

NOTE:
This mic was designed principally for studio and broadcast use. It may also be used for traditional amateur radio applications with the addition of the appropriate XLR cable and HS 2 handswitch or the FS 2 footswitch.
