Stereo pair of condensers”consistent cardioid polar pattern and special low-mass Mylar diaphragm provides better transient response”great for drum overheads.
The Shure KSM137/SL STEREO includes a matched stereo pair of KSM137/SL instrument microphones, two foam windscreens, A27M stereo microphone adapter, and a carry case.
KSM137/SL Instrument Microphone
The KSM137/SL is an end-address condenser microphone with a single cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137/SL can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording instruments.
Versatile, durable, and precise, the KSM137/SL is an outstanding microphone for instruments ranging from percussion to wind, strings to brass, and piano to guitar.
A27M Stereo Microphone Adapter
The included A27M Stereo Microphone Adapter holds two microphones in selectable positions, allowing them to share a stand without losing independent positioning flexibility.
