Shure KSM137SL STEREO

The Shure KSM137/SL Stereo is a matched pair of end-address cardioid condensers chosen and boxed together for stereo recording. Each capsule uses an ultra-thin 24-karat gold-layered Mylar diaphragm and a Class A discrete transformerless preamp, so acoustic guitar, drum overheads, piano, and ensemble work come back fast, detailed, and uncolored. The consistent cardioid pattern makes the pair predictable in XY, ORTF, or spaced arrangements.

A three-position pad (0, 15, 25 dB) lets the mics stand up to extremely loud sources, and a three-position low-frequency filter counters rumble and proximity buildup. A subsonic filter removes mechanical rumble below 17 Hz, and each mic runs on 48V phantom power over XLR. The stereo kit ships with two KSM137 microphones, two stand adapters, two windscreens, an A27M stereo microphone adapter for mounting both on one stand, and a carrying case.
