Shure KSM141/SL ST PAIR Studio Instrument Microphone

KSM141/SL ST PAIR Studio Instrument Microphone description:

The Shure KSM141 SL ST PAIR is a pair of end-addressed condenser microphones with mechanically switching dual polar patterns (cardioid and omnidirectional). Designed for studio use, yet rugged enough for live applications, each KSM141 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments.

Features:

• 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 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
• Low self-noise
• Exceptional reproduction of low-frequency sounds
• Superior common mode rejection and suppression of RFI (radio frequency interference)
• Great for Close miking of acoustic instruments such as piano, guitar, violins, drums, and percussion; Overhead miking of drums and percussion instruments; Electric guitar amplifiers; Brass and woodwind instruments; Room ambience pick-up (guitar amplifier or drums); Orchestras, choirs, wind ensembles; Low-frequency instruments such as double bass and kick drum
• A141SPC Carrying Case, 2 x A100WS Windscreen and 2 x A57F Stand Mount included with this microphone set
