It features a 1-inch, ultra-thin, 2.5-micron, 24-karat gold-layered Mylar diaphragm, which ensures superior transient response and smooth frequency reproduction. The microphone's frequency response ranges from 20Hz to 20kHz, providing a natural and transparent sound suitable for capturing vocals and a variety of instruments.

The KSM42 is equipped with a cardioid polar pattern, effectively minimizing off-axis noise and ensuring focused audio capture. It includes a dual-diaphragm design, which reduces proximity effect and maintains a consistent sound quality across different vocal distances. The microphone integrates an advanced internal shock mount system that minimizes handling noise, further enhancing sound clarity.

A noteworthy feature is the Prethos Advanced Preamplifier Technology, which provides an extremely low self-noise level of just 8.5dB-A, allowing for quiet recordings with exceptional detail and dynamic range. The microphone is capable of handling high sound pressure levels up to 139dB SPL, making it versatile for various recording scenarios.

The KSM42's robust construction includes a durable aluminum housing and a steel grille, ensuring longevity and reliability. It comes with a premium external pop filter and a ShureLock shock mount for added protection against plosives and mechanical vibration. This microphone is an ideal choice for professional studios that demand pristine audio quality and reliability in vocal recording applications.

Shure KSM42 Microphone F.A.Q.

How do I set up the Shure KSM42 for vocal recording?

To set up the Shure KSM42 for vocal recording, connect the microphone to an audio interface using an XLR cable, ensure phantom power is enabled, and position the microphone at about 6-12 inches away from the singer's mouth. Use a pop filter to reduce plosive sounds.

What is the best way to clean the Shure KSM42 microphone?

To clean the Shure KSM42, gently wipe the exterior with a soft, dry cloth. Avoid using any liquid cleaners. For the grille, use a microfiber cloth to remove any dust or debris. Never disassemble the microphone.

How can I reduce background noise when using the Shure KSM42?

To reduce background noise, use the KSM42 in a treated acoustic environment, position the microphone away from noise sources, and use a cardioid polar pattern to focus on the sound source. A noise gate in post-production can also help.

What should I do if my Shure KSM42 is not picking up sound?

Check the XLR cable connections, ensure phantom power is enabled on your audio interface, and verify that your recording software is set to the correct input. If the problem persists, test with a different cable or interface.

Can I use the Shure KSM42 for instruments?

Yes, the Shure KSM42 is versatile and can be used for recording acoustic instruments such as guitar, piano, and strings. Position the microphone appropriately to capture the best tonal quality.

How do I prevent sibilance when recording with the Shure KSM42?

To prevent sibilance, position the microphone slightly off-axis from the singer’s mouth, use a de-esser plugin during mixing, and employ a pop filter to mitigate harsh "S" sounds.

What maintenance does the Shure KSM42 require for long-term use?

Store the microphone in its case when not in use, keep it away from moisture and dust, and regularly check connections and cables for wear. Avoid dropping or subjecting it to physical shocks.

Why is my Shure KSM42 producing a humming noise?

A humming noise may be caused by electrical interference. Ensure all connections are secure, use balanced cables, keep the microphone away from electrical devices, and check the grounding of your audio setup.

Is the Shure KSM42 suitable for live performances?

While the KSM42 is primarily designed for studio use, it can be used for live performances in controlled environments. However, it may be more sensitive to feedback compared to stage mics. Proper monitoring and setup are essential.

How can I troubleshoot distortion issues with my Shure KSM42?

If you're experiencing distortion, check the input gain on your audio interface and ensure it's not set too high. Double-check the positioning of the microphone relative to the sound source and use a pad if needed.
