Dual pattern instrument microphone offers transition between cardioid and omnidirectional patterns and features extended frequency response, pad for handling SPLs, a gold-layered Mylar diaphragm, and a subsonic filter for low frequency rumble. 

A mechanical polar pattern switch for highly consistent cardioid and true omnidirectional polar patterns. Provides flexibility in a wide variety of recording applications
Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar® diaphragm for superior transient response
Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion
Premium electronic components, including gold-plated internal and external connectors
Subsonic filter eliminates low frequency rumble (less than 17 Hz) caused by mechanical vibration
Three-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs)
Three-position switchable low-frequency filter to reduce background noise and counteract proximity effect

Applications

Some typical applications for the KSM141 are listed below. Microphone use, however, is a matter of personal taste. The KSM141 may be used for a variety of applications other than those listed.

Acoustic instruments - such as piano, guitar, drums, percussion, strings
Wind instruments - brass and woodwind
Low frequency instruments - such as double bass, electric bass, kick drum
Overhead miking - drums or percussion
Ensembles - choral or orchestral
Room ambiance pick-up - guitar amplifier or drums
Both the acoustic environment and microphone placement strongly affect the sound obtained from miking a source. You may need to experiment with microphone placement and room treatments to achieve the best overall sound for each application.

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.
