Founded in 1966 by Bob Heil — yes, the same Bob Heil who built the Grateful Dead’s touring sound system in the 1970s — Heil Sound is the broadcast and ham-radio specialty mic brand from Fairview Heights, Illinois. The PR 40 has become a popular budget alternative to the SM7B and RE20.
Heil’s lineup is small — about a dozen mics — but every one is aimed at voice. The PR 40 is the flagship: a large-diaphragm dynamic meant for podcast and broadcast use. The PR 30 is similar at a lower price.
