This is the Black Fin with White LEDS. Heil Sound is pleased to introduce The Fin, exhibiting a remarkable, natural, clear sound and designed especially for live sound, recording and broadcast applications. The exceptional performance is achieved by the use of a special magnet structure with a large 1 1/8” aluminum low mass voice coil assembly similar to the Heil PR 20. The frequency response is 50 Hz – 18 kHz with that traditional Heil Sound mid range ‘bouquet’ at 4 kHz, which presents incredible brilliance and presence. The Fin exhibits a tight linear cardioid pattern. The all steel body comes in a matte black finish for a timeless look. A blue molded internal foam windscreen inside the grill covers the Heil dynamic microphone element mounted in a specially tooled rubber shock mount. The fun part of the new Heil The Fin is the four white L.E.D. 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 + 48 volt d.c. phantom voltage down the balanced mic line. The FIN also comes with standard 5/8” – 27 microphone stand threads which allow it to be mounted on booms or floor stands. The microphone audio will also work into an unbalanced low impedance input used on amateur radios, communications audio or simple public announcement systems. None of these will have the proper voltage to illuminate the lamps but the microphone will work perfectly. Should you want to illuminate the lamps when used for amateur radio, etc. The FIN can be used into one of the balanced inputs of a small Behringer UB 802 (or similar) mixer or the 3 pin XLR balanced of a W2IHY 8 band equalizer, with their phantom power activated. The FIN is terrific for vocals, instrument amplifiers, harmonica, and speech, and puts the FUN back into the dynamic microphone.
