The Fin dynamic mic captures remarkably natural, clear sound and is designed for live sound, recording and broadcast applications. The exceptional performance is achieved thanks to a special magnet structure with a large 1-1/18" aluminum low-mass voice-coil assembly similar to the Heil PR 20. The frequency response is 60Hz–18kHz with that traditional Heil Sound mid-range "bouquet" at 4kHz, presenting incredible brilliance and presence. The Heil Fin exhibits a tight linear cardioid pattern. The chrome finish is a special "showchrome," where the steel body is copper-plated and then double chrome-plated, producing a deep chrome finish. A blue molded internal foam windscreen inside the grille covers the large-diameter Heil dynamic microphone element mounted in a specially tooled Sorbothane shockmount.

The fun part of The Fin is the four LED lamps mounted inside. These can only be illuminated when using The Fin into one of the 3-pin balanced XLR inputs of a professional mixing console that supplies a +48V DC phantom voltage down the balanced mic line. Standard 5/8" 27-thread connection allows The Fin to be mounted on booms or floor stands.

The Fin mic from Heil Sound is terrific for vocals, instrument amplifiers, harmonica and speech, and puts the fun back into the dynamic microphone.
