Shure 401B Microphone Specification

The Shure 401B Microphone is a professional-grade dynamic microphone designed for versatile audio applications, offering superior performance and durability. It features a cardioid polar pattern that ensures excellent off-axis rejection, making it ideal for minimizing background noise and focusing on the main sound source. The microphone is equipped with a diaphragm tailored for a smooth and extended frequency response, ranging from 50 Hz to 15 kHz, which captures both vocals and instruments with clarity and precision.

The Shure 401B incorporates a pneumatic shock-mount system that significantly reduces handling noise, ensuring clean audio capture even in dynamic environments. Its robust construction includes a die-cast metal casing and a hardened steel mesh grille, providing exceptional durability and resistance to wear and tear, making it suitable for both studio and live settings.

Connectivity is facilitated by a standard XLR output, ensuring compatibility with a wide range of audio equipment. The microphone operates with low impedance (150 ohms), which allows for long cable runs without signal loss, maintaining audio integrity. Its compact size and lightweight nature, weighing approximately 260 grams, offer ease of use and portability.

The Shure 401B's design and engineering emphasize reliability and sound quality, making it a preferred choice for professionals in broadcasting, recording studios, and live sound environments. Its ability to handle high sound pressure levels without distortion further enhances its versatility, making it suitable for a wide range of applications from quiet studio recordings to loud stage performances.

How do I properly set up the Shure 401B Microphone for live performances?

To set up the Shure 401B Microphone for live performances, connect the microphone to a mixer or audio interface using an XLR cable. Ensure the mixer provides phantom power if required, and position the microphone at an optimal distance from the sound source to avoid feedback.

What is the best way to reduce background noise with the Shure 401B?

To reduce background noise, use a cardioid pickup pattern to focus on the sound source. Additionally, employ a windscreen or pop filter to minimize plosives and environmental noise, and adjust the microphone's gain settings appropriately.

How can I troubleshoot a lack of sound from my Shure 401B Microphone?

First, check all connections to ensure the microphone is securely plugged in. Verify that the mixer or interface is powered on and supplying phantom power if needed. Test the microphone with another cable or input to rule out hardware issues.

What steps should I take for regular maintenance of the Shure 401B Microphone?

Regularly clean the microphone grill with a soft brush and mild detergent to remove dust and debris. Avoid exposing the microphone to extreme temperatures or humidity, and store it in a protective case when not in use.

How do I connect the Shure 401B to a computer for recording?

To connect the Shure 401B to a computer, use an audio interface with XLR input. Connect the microphone to the interface with an XLR cable and then connect the interface to the computer via USB or another compatible connection. Ensure the interface drivers are installed and configured.

What should I do if the Shure 401B picks up unwanted feedback during a performance?

To reduce feedback, reposition the microphone away from speakers and monitor its directionality. Lower the gain or volume levels, and use equalization to cut problematic frequencies.

How can I improve the clarity of vocals when using the Shure 401B Microphone?

Position the microphone at the proper distance from the vocalist, typically 6-12 inches. Use a pop filter to reduce plosives and adjust EQ settings to enhance vocal frequencies. Ensure the microphone is pointed directly at the sound source for optimal clarity.

Can I use the Shure 401B Microphone outdoors, and what precautions should I take?

Yes, the Shure 401B can be used outdoors, but it is advisable to use a windscreen to minimize wind noise. Ensure the microphone is protected from moisture and extreme weather conditions, and monitor environmental sound levels to adjust settings accordingly.

What are the common signs that my Shure 401B Microphone might need servicing?

Common signs include noticeable drop in audio quality, intermittent sound, visible damage to the microphone or cable, and failure to power on when connected to a proper source. If any of these occur, consider professional servicing.
