Shure KSM137 Microphone Specification

The Shure KSM137 is a premium cardioid condenser microphone designed for studio and live sound applications. It features a highly durable, low-mass diaphragm that delivers an extended frequency response, making it ideal for capturing detailed and accurate sound. The microphone's frequency range spans from 20 Hz to 20 kHz, ensuring it can handle a wide array of instruments and vocal performances. The KSM137 is equipped with a switchable 15 dB pad, allowing it to manage high sound pressure levels up to 139 dB SPL without distortion, which is particularly useful for recording loud sound sources like drums and amplifiers.

The microphone's preamplifier is transformerless, contributing to its low self-noise of 14 dB-A, ensuring clear audio capture with minimal interference. The cardioid polar pattern of the KSM137 offers excellent off-axis rejection, making it suitable for isolating the desired sound source in environments with background noise. Additionally, a three-position switchable low-frequency filter helps reduce unwanted rumble and handling noise, providing greater flexibility in diverse recording situations.

Constructed with a robust metal chassis, the KSM137 is built to withstand the rigors of both studio and on-the-road use. Its compact design and lightweight build make it easy to position in tight spaces or on busy stages.

Shure KSM137 Microphone F.A.Q.

How do I connect the Shure KSM137 to an audio interface?

To connect the Shure KSM137 to an audio interface, use an XLR cable. Plug one end into the microphone and the other end into the XLR input of your audio interface. Ensure that the interface provides phantom power, as the KSM137 requires it to operate.

What is the best way to position the KSM137 for recording acoustic guitar?

For recording acoustic guitar, position the KSM137 about 6 to 12 inches away from the guitar, aiming at the 12th fret. Adjust the angle and distance to capture the desired balance between the bass and treble frequencies.

How can I reduce unwanted noise when using the KSM137?

To reduce unwanted noise, ensure the microphone is properly isolated from vibrations using a shock mount. Use the low-frequency roll-off switch on the KSM137 to minimize low-end rumble and background noise.

Why is my KSM137 not producing any sound?

If the KSM137 is not producing sound, check that the XLR cable is securely connected and the audio interface or mixer is supplying phantom power. Ensure the gain is appropriately set and the microphone is not muted on the interface or software.

What maintenance does the KSM137 microphone require?

Regularly clean the KSM137 with a dry, lint-free cloth. Store it in a dry, cool place and transport it in its protective case to prevent damage. Avoid exposing the microphone to moisture and extreme temperatures.

Can the KSM137 be used for live sound applications?

Yes, the KSM137 can be used for live sound applications. Its cardioid polar pattern helps isolate the sound source and reduce feedback, making it suitable for various instruments and vocal performances on stage.

How do I switch between the different attenuation settings on the KSM137?

The KSM137 features a switchable pad with settings of 0dB, -15dB, and -25dB. Use the switch on the microphone body to select the desired attenuation level, which helps manage high sound pressure levels without distortion.

What should I do if the KSM137 picks up too much environmental noise?

If the KSM137 picks up excessive environmental noise, try repositioning the microphone closer to the sound source. Use acoustic treatment in the recording space and engage the low-frequency roll-off to reduce ambient noise.

Is the KSM137 suitable for recording vocals?

While the KSM137 is primarily designed for instruments, it can also be used for recording vocals. Its flat frequency response provides natural sound reproduction, making it a versatile choice for various recording applications.

How do I prevent distortion when using the KSM137 with loud sound sources?

To prevent distortion with loud sound sources, use the built-in attenuator switch on the KSM137. Select the -15dB or -25dB pad setting to manage high sound pressure levels effectively.
