SHURE SM137 – Instrument Microphone

The SM137 is a versatile, flat-response cardioid condenser probe microphone.

The SM137 has an ultra-thin diaphragm for a frequency response that combines a smooth high-end with a tight, controlled low-end and a 15db pad for natural sound reproduction in both acoustic and high volume performance applications.

NEW Wider mounting base capable of accommodating a larger range of microphone stands. Even works with the LP Claw.

Specifically engineered for drum and instrument applications, the Beta 56A's compact, pivoting design makes it the ideal choice for these applications.

Its extremely uniform supercardioid pickup pattern provides high gain before feedback and excellent rejection of unwanted noise. A built-in dynamic locking stand adapter with an integral XLR connector simplifies installation. The stand adapter keeps the microphone securely in place, even if it is struck by a drumstick. Typical Beta 56A applications include close miking of tom-toms and other percussion instruments, as well as guitar amplifiers, brass instruments, and woodwinds.

• Built-in stand adapter with dynamic locking system and XLR connector simplifies setup and provides greater flexibility
• Uniform supercardioid pattern for high gain-before-feedback and superior rejection of off-axis sound
• Compact design reduces stage clutters
• Hardened steel mesh grille resists wear and abuse
• Neodymium magnet for high signal-to-noise ratio output
• Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
• Frequency response: 50 to 16,000 Hz
