The Shure KSM137/SL Condenser Microphone is an end-address condenser microphone with a cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137 can withstand extremely high sound pressure levels.
The Shure KSM137/SL Condenser Microphone is a premium end-address cardioid instrument microphone engineered for highly critical studio recording and live sound productions. Its class A, discrete, transformerless preamplifier provides extremely natural response and transparent sound capture, and a three position switchable pad allows for handling of extremely high sound pressure levels. Versatile, durable, and precise, the Shure KSM137/SL is an outstanding microphone for both live and studio applications. The Shure KSM137/SL is used for close-miking the acoustic and electric instruments, drum overheads, brass/woodwind, ensembles, and even bass instruments such as double bass and kick drum. The Shure KSM137/SL is equally at home in the studio or in live applications. The Shure KSM137/SL Cardioid Instrument Microphone can withstand extremely high sound pressure levels (SPL). It has a high output level, low self noise and reproduces low frequency sounds exceptionally well.
