Shure SM93 Lavaliermikrofoni

Shure SM93 rintanappimikrofoni

Monisuuntainen miniatyyrimikrofoni tarjoaa täydellisen, selkeän äänen puhesovelluksissa, kuten lähetyksissä ja luennoissa. Ominaisuuksiin kuuluu tasainen laajennettu taajuusvaste ja monipuoliset asennustarvikkeet vähäisen näkyvyyden takaamiseksi.

The SM93 is supplied with a sew-on mounting bracket, a mounting block with attached tie bar, and an acoustic windscreen to minimize wind noise in outdoor applications. It is also supplied with a dual mounting block with attached tie bar.

Features:
- Subminiature lavalier design; ideal size for theater, television broadcasting, video, film, and sound reinforcement
- Small, inconspicuous mounting hardware
- Full, clear sound comparable to larger microphones
- Smooth extended frequency response with presence rise specially tailored for chest-worn microphone operation
- Controlled low-frequency rolloff reduces low-frequency clothing and room noise
- Low distortion, wide dynamic range
- Uniform omnidirectional polar pattern
- Preamplifier assembly (SM93) can be pocketed, strapped to the body, or clipped to belt or waistband
- Wide-range phantom powering (SM93) accepts all commonly used voltages
