Renowned for its superior performance, the BETA58A features a tailored frequency response that accentuates vocals while ensuring clarity and warmth. Its frequency range spans from 50 Hz to 16 kHz, providing a detailed sound reproduction with a slight presence boost at the midrange and bass roll-off to control the proximity effect. The supercardioid pattern offers maximum isolation from other sound sources, minimizing feedback and unwanted noise, which is critical in live sound environments.

The microphone's neodymium magnet contributes to its high signal-to-noise ratio, resulting in a strong output level and excellent sensitivity. Engineered for durability, the BETA58A incorporates a rugged steel mesh grille that resists wear and abuse, as well as an advanced pneumatic shock-mount system that reduces handling noise. The microphone's construction ensures reliability in demanding settings, withstanding rough handling and adverse conditions.

The BETA58A has a nominal impedance of 290 ohms and a sensitivity of -51 dBV/Pa, making it compatible with a wide range of audio equipment. It connects via a standard 3-pin XLR connector, ensuring secure and stable connectivity. Its robust build, consistent performance, and precise sound characteristics make the Shure BETA58A a preferred choice for vocalists and audio professionals seeking a dependable microphone for live performances and studio applications.

Shure BETA58A Microphone F.A.Q.

How do I connect the Shure BETA58A microphone to a mixer?

To connect the Shure BETA58A to a mixer, use an XLR cable. Plug the female end into the microphone and the male end into an XLR input on your mixer. Ensure phantom power is off, as the BETA58A does not require it.

What is the best way to position the Shure BETA58A for live vocals?

For optimal sound, position the BETA58A directly in front of the vocalist's mouth, about 1-3 inches away. This helps capture the full range of the voice while minimizing feedback and ambient noise.

How can I reduce feedback when using the BETA58A on stage?

To reduce feedback, ensure proper microphone positioning, use stage monitors carefully, and apply EQ adjustments to reduce frequencies prone to feedback. Also, avoid pointing the microphone directly at speakers.

What maintenance is required for a Shure BETA58A microphone?

Regularly clean the microphone grille with a mild detergent and warm water. Avoid getting moisture inside the microphone. Periodically check the internal foam windscreen for cleanliness and replace if damaged.

Why is my BETA58A microphone not producing any sound?

Check cable connections and ensure the mixer channel is not muted. Verify that the XLR cable and input are functioning properly. Also, test the microphone with another audio system to rule out hardware issues.

Can the BETA58A be used for instruments as well as vocals?

Yes, the BETA58A can be used for instruments, particularly for amplifying live instruments like guitars and drums. Experiment with placement to achieve the desired sound quality.

How does the BETA58A differ from the SM58?

The BETA58A has a supercardioid polar pattern which provides better isolation from other sound sources, and it has a slightly higher output level and a tailored frequency response, offering a brighter sound than the SM58.

What should I do if my BETA58A experiences distortion?

If distortion occurs, ensure that the gain levels on your mixer are set correctly and not too high. Check that the microphone is properly connected and test it with another cable.

How do I safely transport the BETA58A microphone?

Use a padded microphone case to protect the BETA58A during transport. Store the microphone in a dry environment and avoid exposing it to extreme temperatures.

Is the BETA58A suitable for outdoor performances?

Yes, the BETA58A is suitable for outdoor performances due to its rugged design and minimal handling noise. However, consider using a windscreen to reduce wind interference.
