SupercardioidHeil Sound PR 30 B

Supercardioid Dynamic Microphone

The PR 30 B is and end-address dynamic mic designed for broadcast voice. It is identical to the PR-30, but finished in black with a red end grille.

Heil describes the mic as having a Cardioid pattern, but the published polar chart shows a small lobe at 180°, indicating that the mic’s pattern is more accurately described as Supercardioid.

For more information, see the PR-30 profile (linked from the sidebar).
