Shure SM27 Microphone Specification

The Shure SM27 is a professional-grade condenser microphone designed for versatile applications in both studio and live performance settings. It features a large-diaphragm, side-address design that delivers a flat, neutral frequency response, making it ideal for capturing natural sound across a wide range of sources, including vocals, acoustic instruments, and amplified sound. The microphone's frequency response spans from 20 Hz to 20 kHz, providing a detailed and accurate sound reproduction.

Equipped with a cardioid polar pattern, the SM27 effectively isolates the desired sound source while minimizing background noise and feedback, making it suitable for both controlled studio environments and live stage performances. The microphone incorporates a low self-noise level, enhancing its ability to capture subtle nuances in audio without introducing unwanted noise.

The SM27 features a switchable 15 dB pad, allowing it to handle high sound pressure levels up to 152 dB SPL without distortion, making it capable of recording loud sources like electric guitars and percussion. Additionally, it includes a three-position switchable low-frequency filter, offering options to reduce unwanted low-end rumble and proximity effect.

Constructed with a durable metal chassis and a stainless steel grille, the Shure SM27 is built to withstand the rigors of regular use, ensuring longevity and reliability. Its internal shock mount system reduces handling noise, further ensuring clean recordings. The microphone requires 48V phantom power for operation, a standard for professional condenser microphones. Overall, the Shure SM27 is a robust and versatile microphone that meets the demands of both professional and enthusiastic amateur audio engineers seeking high-quality sound capture for a variety of applications.

Shure SM27 Microphone F.A.Q.

How do I connect the Shure SM27 to an audio interface?

To connect the Shure SM27 to an audio interface, use an XLR cable. Connect one end to the microphone and the other end to the XLR input on your audio interface. Ensure that phantom power is enabled on the interface, as the SM27 requires it to operate.

What is the best way to position the Shure SM27 for vocal recording?

For optimal vocal recording, position the SM27 about 6 to 12 inches away from the singer's mouth and slightly off-axis to reduce plosive sounds. Utilize a pop filter to further minimize plosives and protect the microphone.

How can I reduce background noise when using the Shure SM27?

To reduce background noise, use the SM27's cardioid polar pattern to your advantage by aiming the microphone away from noise sources. Additionally, record in a treated room and use noise reduction software during post-processing.

What maintenance does the Shure SM27 require?

The Shure SM27 requires minimal maintenance. Regularly clean the exterior with a soft, dry cloth. Avoid exposing the microphone to moisture and extreme temperatures. Store it in a protective case when not in use.

How can I troubleshoot low output levels from the Shure SM27?

First, ensure that phantom power is enabled on your audio interface. Check the XLR cable for any damage or loose connections. If the issue persists, test the microphone with a different interface or mixer to rule out hardware problems.

Is the Shure SM27 suitable for instrument recording?

Yes, the Shure SM27 is versatile and can be used for recording a variety of instruments. It works well with acoustic guitars, pianos, and drums, providing a clear and detailed sound. Experiment with placement to find the best sound for each instrument.

What features of the Shure SM27 help with recording clarity?

The Shure SM27 features a low-mass, large Mylar diaphragm and a flat frequency response, which help capture accurate and detailed audio. Its cardioid polar pattern minimizes background noise, enhancing recording clarity.

How do I use the high-pass filter on the Shure SM27?

The SM27 has a switchable high-pass filter to reduce low-frequency rumble or handling noise. To activate it, slide the switch on the back of the microphone to the desired position. This is useful in live sound or when recording bass-heavy sources.

Can the Shure SM27 handle high sound pressure levels?

Yes, the Shure SM27 can handle high sound pressure levels up to 147 dB SPL. It is suitable for recording loud sound sources, such as drums and amplifiers, without distortion.

What is the best way to prevent plosives when using the Shure SM27?

To prevent plosives, use a pop filter between the vocalist and the microphone. Position the microphone slightly off-axis and ensure the singer maintains consistent distance. This setup helps diffuse the air pressure from plosive sounds.
