Shure KSM141 Dual Pattern Condenser Mic Champagne

Description

The KSM141 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 KSM141 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments.

The KSM141 features extended frequency response, pad for handling SPLs, a gold-layered Mylar diaphragm and a subsonic filter for low frequency rumble. Both the acoustic environment and microphone placement strongly affect the sound obtained from miking a source. You may need to experiment with where you place the KSM141 mic and your room treatments to achieve the best overall sound for each application.
