Since 1982, Heil Sound has been the leading manufacturer of
communications microphones and has a paramount understanding of
phasing. When properly applied, this knowledge creates outstanding
cardiod patterns with unbelievable rear rejection that removes unwanted
sounds that try to enter from the off axis rear. The pattern control of
the Heil PR 20 is outstanding. This exceptional performance is achieved
by using the ideal combination of materials for the large low mass
diaphragm and a special mixture of neodymium, iron, and boron that
gives the PR 20 the strongest magnet structure available.
In
addition to the special magnet structure, the PR 20 achieves its
exceptional performance by using a large 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, entering them
out of phase. Thus, the PR 20 produces a very linear cardiod pattern
and reduces the proximity effect while achieving perfect articulation.
This new Heil element is usable in extreme high sound pressure levels
and is immune to overload conditions making it perfect for vocal and
live sound applications.
The PR 20 is supplied with a leatherette carrying bag, a mic clip
and three metal wind screens (black, silver and gold).
