The KSM137/SL ST PAIR from Shure is a stereo pair of cardioid condenser studio microphones designed for instrument recording and sound reinforcement. The KSM137/SL offers a wide 20 Hz to 20 kHz frequency response making it a flexible microphone for a variety of applications. The KSM137/SL features a cardioid element and permanently biased transducer design resulting in clean, accurate signal reproduction and frequency response. The transformer-less, class-A output circuitry provides a noise free output signal path while maintaining high gain levels. The tight cardioid pattern is effective in attenuating off-axis signal due to room ambiance, instruments, monitor noise etc.
Features:
A highly consistent cardioid polar pattern
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 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 reduces background noise and counteracts proximity effect
