Dual Pattern Instrument Microphone

The Shure KSM Microphone Series KSM 141 is a dual-pattern end-addressed condenser microphone with a rotating collar, allowing easy switching between a consistent cardioid or true omnidirectional polar pattern for smooth and extremely focused sound reproduction.

Designed for studio use, yet rugged enough for live applications, the KSM-141 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments.
