Shure KSM137

Instrument Condenser Microphone

Shure KSM137 is a premium end-address condenser microphone designed for critical instrument and live sound applications. With a consistent cardioid polar pattern, fast transient response, and selectable pad and low-frequency filter options, it is a strong choice for studios, stages, drum overheads, acoustic instruments, brass, strings, and amplified sources.

Shure KSM137 Competitive Differences

• Ultra-thin 2.5 micron, 24-karat gold-layered Mylar diaphragm for accurate transient response
• Class A, discrete, transformerless preamplifier for transparent sound with low distortion
• Three-position attenuation switch with 0 dB, -15 dB, and -25 dB settings for high SPL sources
• Three-position low-frequency filter for controlling rumble, stand noise, and proximity effect
• Highly consistent cardioid pattern for strong isolation and focused pickup

Shure KSM137 Description

The Shure KSM137 is built for users who need a precise, natural-sounding microphone for both recording and reinforcement. Its condenser design and cardioid pickup pattern make it especially useful when you want to capture detail while reducing unwanted room sound and bleed from nearby sources.

Its Class A, transformerless preamplifier helps preserve transient detail and clarity, which is especially valuable on percussion, acoustic guitar, piano, strings, and overhead drum applications. The microphone is also designed to handle demanding sound sources, making it a reliable option for close-miking louder instruments such as brass, guitar cabinets, and percussion.

Flexible onboard controls make the KSM137 easy to adapt to different setups. The switchable attenuation pad helps manage extremely high sound pressure levels, while the low-frequency filter provides useful control over rumble and excess low end. For engineers, musicians, houses of worship, and production teams that need a dependable small-diaphragm condenser with studio-grade detail, the KSM137 is a versatile solution.
