The Fostex Model M115
moving coil microphone

Fostex M115

The M115 is a high-quality moving coil microphone with a flexible shaft, designed for professional, commercial, and industrial applica­tions where superior performance and appearance are required. The microphone body and flex shaft are small to allow unobtrusive posi­tioning and a unique, thin diameter flex shaft design produces a smooth, quality feel not normally found in a flex shaft microphone.

Handling and vibration-generated noise are kept to a minimum through a highly effective isolation and suspension system. The M115 has a tailored response for high speech intelli­gibility and a hypercardioid pattern for reduced feedback and ambient noise pick-up. The built-in pop filter reduces wind and breath noise. The M115 case houses an on-off switch and an XLR connector for direct mounting on the console or podium. The 600-ohm output im­pedance is suitable for most low-impedance microphone inputs. The microphone is finished in matte metal to reduce glare in television and live use. The Fostex M115 is well-suited for a multitude of applications including churches, restaurants (paging), broad­cast and re­cording studios (talkback), as well as other industrial and commercial uses.
