    Tính năng sản phẩm: Instrument Microphone Shure KSM137/SL STEREO

    - 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 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
    - Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
    - 3-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs)
    - 3-position switchable low-frequency filter reduces background noise and counteracts proximity effect
