The Shure KSM137 is an end-address condenser microphone with a cardioid polar pattern. Designed for both studio and live use, the KSM137 mic can withstand extremely high sound pressure levels. Its low self-noise and extended frequency response make the Shure KSM137 ideal for recording acoustic guitar, drum overheads, and hi-hats. Other features include Shure's Class A transformerless preamp circuitry for transparency; extremely fast transient response with minimal distortion; a highly sensitive 2.5-micron gold-layered mylar diaphragm; and a switchable, 3-position low-frequency filter to limit unwanted background noise and proximity effect. The Shure KSM137 microphone can capture sounds between 20Hz and 20kHz. Set includes 2 mics, 2 break-resistant mic clips, carrying case, and 2 Popper Stopper windscreens.
