Shure KSM137/SL ST PAIR Cardioid Microphone (Stereo Pair)

The Shure KSM137/SL STEREO is a matched pair of small-diaphragm microphones built for engineers and musicians who need reliable stereo capture in the studio or on stage. Each microphone uses a cardioid condenser design that focuses on the source while controlling bleed from the sides and rear, so you get a clean, well-defined image whether you are recording a piano in a concert hall or cymbals in a rehearsal room.

At the heart of the capsule sits a thin, gold-layered Mylar diaphragm that responds quickly to transients. A class A, transformerless preamp then carries that detail to your interface or mixer with minimal coloration, giving you an open sound that translates naturally across the 20 Hz to 20 kHz range.

Flexibility is built in. A three-position pad lets you choose 0 dB, 15 dB, or 25 dB of attenuation, so a pair can move from delicate string quartets to loud brass sections or close-miked drums without overloading. When low-frequency rumble or proximity effect becomes an issue, engage the switchable low-cut filter to tighten the bottom end before the signal ever reaches your preamp.

The robust metal bodies stand up to daily use, and the XLR outputs integrate easily with standard phantom-powered setups. From capturing a balanced stereo image of an acoustic guitar and vocal duo, to serving as overheads for a live jazz kit, the KSM137/SL STEREO pair delivers consistent, transparent results session after session.
