The KSM141 is a large diaphragm end-addressed condenser microphone with a rotating collar allowing easy switching between a highly 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.

Signal to Noise Ratio**
•80 dB
*20 Hz to 20 kHz; THD < 1%. THD of the microphone preamplifier when applied input signal is equivalent to the cartridge output at specified SPL.
**S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.
