Shure SM51 1967 Microphone Specification

The Shure SM51, introduced in 1967, is a dynamic cardioid microphone designed for versatile audio applications. It features a robust construction that is ideal for both studio recording and live sound environments. This microphone is engineered to provide a smooth and natural sound reproduction, making it suitable for capturing vocals and various instruments. The cardioid polar pattern of the SM51 ensures effective rejection of off-axis noise, minimizing feedback and unwanted ambient sound, thus enhancing the clarity and focus of the audio source.

The frequency response of the Shure SM51 ranges from 50 Hz to 15 kHz, offering a balanced audio output with a presence boost that enhances vocal intelligibility and instrumental detail. This frequency range ensures the microphone can capture a wide spectrum of sounds while maintaining a natural tonal quality. The design incorporates a pneumatic shock mount system, reducing handling noise and mechanical vibrations that could interfere with the audio quality.

Additionally, the Shure SM51 is equipped with a durable die-cast metal housing and a hardened steel mesh grille, providing exceptional durability and reliability in demanding environments. The microphone's impedance is optimized for compatibility with a wide range of audio equipment, ensuring seamless integration into existing setups. With its combination of durability, sound quality, and reliability, the Shure SM51 remains a classic choice for both professional and amateur audio enthusiasts alike. Its legacy in the audio industry is marked by its consistent performance and the trust it has garnered among users over the decades.

Shure SM51 1967 Microphone F.A.Q.

How do I set up the Shure SM51 microphone for optimal sound quality?

To set up the Shure SM51 for optimal sound quality, first ensure the microphone is connected to a high-quality preamp. Position the microphone about 6-12 inches away from the sound source, slightly off-axis to reduce plosive sounds. Adjust the gain on your audio interface or mixer so that the input level peaks around -12 dBFS.

What should I do if my Shure SM51 microphone is producing a lot of background noise?

If your Shure SM51 is producing background noise, check the cable connections for any loose or damaged parts. Ensure that the microphone is properly grounded. Try using a different cable or audio interface to rule out equipment issues. Additionally, use a noise gate or low-cut filter to minimize unwanted ambient sounds.

How can I clean and maintain my Shure SM51 microphone?

To clean the Shure SM51, gently wipe the exterior with a soft, damp cloth. Avoid getting moisture inside the microphone grille. For deeper cleaning, you can carefully unscrew the grille and use compressed air to remove any dust or debris. Regular maintenance includes storing the microphone in a dry, dust-free environment when not in use.

Why is my Shure SM51 not picking up sound?

If your Shure SM51 is not picking up sound, verify that all cables are securely connected and that your input device is powered on. Check the phantom power setting if using an audio interface that requires it. Test the microphone with a different cable or input to rule out a faulty connection.

What is the best way to reduce feedback when using the Shure SM51?

To reduce feedback with the Shure SM51, position speakers away from the microphone and aim them towards the audience, not the microphone. Use a graphic equalizer to cut frequencies that are causing feedback. Additionally, try lowering the microphone gain or using a directional microphone pattern to minimize feedback.

Can I use the Shure SM51 with a wireless system?

The Shure SM51 can be used with a wireless system if you have the appropriate wireless transmitter that supports the microphone's XLR connection. Ensure that the wireless system is compatible with dynamic microphones for optimal performance.

How do I fix distortion issues with my Shure SM51?

If you're experiencing distortion with the Shure SM51, first check the input gain on your audio interface or mixer and ensure it's not too high. Lower the gain if necessary. Additionally, examine the microphone cable for any damage, as a faulty cable can also cause distortion.

What are common uses for the Shure SM51 microphone?

The Shure SM51 is commonly used for vocal performances, broadcasting, and recording instruments such as acoustic guitars and drums. Its durable build and clear sound reproduction make it a versatile choice for various audio applications.

How can I improve the sound isolation for the Shure SM51 in a noisy environment?

To improve sound isolation for the Shure SM51 in noisy environments, use a microphone isolation shield to block ambient noise. Additionally, consider using soundproofing materials in the recording area and setting the microphone closer to the sound source to capture more direct sound.

Is it necessary to use a pop filter with the Shure SM51?

While the Shure SM51 has some built-in wind protection, using a pop filter is recommended to further reduce plosive sounds during vocal recordings. A pop filter helps maintain sound clarity and protect the microphone from saliva.
