Shure KSM27 Microphone Specification

The Shure KSM27 is a large-diaphragm condenser microphone designed for professional studio and live sound applications. It features a one-inch, externally biased, ultra-thin, 24-karat gold-layered Mylar diaphragm that ensures superior transient response and maximum SPL handling. The microphone operates on a cardioid polar pattern, providing excellent off-axis rejection and reducing unwanted background noise, which makes it ideal for vocal and instrumental recordings. With a frequency response range of 20 Hz to 20 kHz, the KSM27 captures a wide spectrum of sounds with exceptional clarity and detail.

The microphone is equipped with a switchable low-frequency filter with three positions: flat, 15 dB/octave at 80 Hz, and 18 dB/octave at 115 Hz, allowing users to minimize unwanted low-frequency rumble or proximity effect. Additionally, a switchable -15 dB pad is included to accommodate high sound pressure levels, making it versatile for capturing loud sound sources without distortion.

Constructed with a rugged die-cast aluminum body and a steel grille, the KSM27 is designed to withstand the rigors of both studio and stage environments. It also features an advanced internal shock mount system that reduces mechanical noise and handling vibrations. For connectivity, the microphone uses a standard three-pin XLR connector, ensuring compatibility with most audio interfaces and mixers. Phantom power of 48 volts is required for operation.

The Shure KSM27 provides a blend of durability, precision, and versatility, making it suitable for a wide range of applications, from vocal performances to capturing acoustic instruments. Its robust design and advanced features cater to the needs of professional audio engineers and musicians seeking reliable and high-quality sound reproduction.

Shure KSM27 Microphone F.A.Q.

How do I properly connect the Shure KSM27 to an audio interface?

To connect the Shure KSM27 to an audio interface, use an XLR cable to connect the microphone to the interface's XLR input. Ensure that phantom power is enabled on the interface, as the KSM27 requires it to operate.

What are the ideal usage scenarios for the Shure KSM27 microphone?

The Shure KSM27 is ideal for studio recording, podcasting, and live performances. Its flat frequency response makes it suitable for capturing vocals, acoustic instruments, and as a drum overhead.

How can I minimize background noise when using the KSM27?

To minimize background noise, ensure the microphone is positioned close to the sound source. Use the cardioid polar pattern effectively and consider using a pop filter or acoustic treatment in your recording environment.

What maintenance does the Shure KSM27 require?

Regular maintenance for the Shure KSM27 includes keeping it clean and dust-free. Store the microphone in a dry, safe place when not in use and use a protective case for transportation. Periodically check and clean the grille and connectors.

How should I position the Shure KSM27 for vocal recording?

Position the Shure KSM27 about 6 to 12 inches away from the vocalist, slightly below or above the mouth to avoid plosive sounds. Adjust the angle to capture the best tonal quality and use a pop filter to reduce plosives.

What should I do if the KSM27 is not producing any sound?

Check that the XLR cable is securely connected and test with a different cable if necessary. Ensure that phantom power is turned on at the audio interface or mixer. Verify that the input channel is not muted and the gain is appropriately set.

Can the Shure KSM27 handle high sound pressure levels?

Yes, the Shure KSM27 can handle high sound pressure levels up to 139 dB SPL. It's suitable for miking loud instruments like drums and guitar amplifiers without distortion.

Is the Shure KSM27 suitable for live performances?

While primarily designed for studio use, the Shure KSM27 can be used for live performances. Its durability and sound quality make it a reliable choice for live vocal and instrument miking.

What type of pop filter is recommended for the Shure KSM27?

A standard nylon mesh pop filter is recommended for the Shure KSM27. It helps reduce plosive sounds without affecting the microphone's frequency response.

How do I prevent feedback when using the KSM27 in a live setting?

To prevent feedback, position the KSM27 away from speakers and monitors. Use the cardioid pattern to your advantage by aiming the microphone's rear towards the sources of noise and adjust the sound system's EQ settings to reduce problem frequencies.
