The Shure KSM137/SL Microphones deliver the same detailed, transparent performance that has made the KSM137 a trusted choice in professional studios and live rigs worldwide, but in a precision-matched stereo configuration.
Designed for accurate stereo imaging and natural instrument reproduction, the KSM137 Stereo Pair excels on drum overheads, piano, acoustic guitar, orchestral recording, choirs, percussion, room capture, and ensemble applications where balance and realism matter most. Each microphone in the pair features an ultra-thin 2.5 micron, 24 karat gold-layered Mylar diaphragm paired with a Class A, transformerless preamp design for exceptionally fast transient response and low-noise operation. The result is a clean, articulate sound with excellent depth and detail that works equally well in critical studio recording and demanding live environments. The KSM137 Stereo Pair also offers the flexibility engineers need when working across a wide range of sound sources. Built-in switchable pads allow the microphones to handle extremely high SPL sources like drums and amplifiers, while selectable low-frequency filters help minimize rumble, stage vibration, and proximity effect. Whether you are capturing a full grand piano, stereo acoustic guitar, or expansive room ambience, the KSM137 Stereo Pair delivers dependable, professional-quality stereo recording performance.
