SHURE KSM-27SL – Large Single-Diaphragm Microphone 20Hz to 20kHz

The Shure KSM27 is a side-address condenser microphone with a cardioid polar pattern. Designed for studio use, but rugged enough for live applications, the KSM27 has an externally biased, 1-inch diaphragm, extremely low self-noise, and an extended frequency response specially tailored for vocal tracking and instrument recording.

Features

• Cardioid polar pattern - the most commonly used pattern for both studio and live applications
• 1 inch, externally biased, ultra-thin, 24 Karat gold-layered, low mass, Mylar? diaphragm provides superior transient response
• Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response and no crossover distortion, while minimizing harmonic and intermodulation distortions
• Premium electronic components and gold-plated internal and external connectors
• Subsonic filter eliminates rumble from mechanical vibration below 17 Hz
• Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
• 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect
• Integrated three-stage 'pop" protection grille reduces plosives and other breath noise
• Internal shock mount reduces handling and stand noise

Performance Characteristics

• Extended frequency response
• Low self noise
• Exceptional low-frequency reproduction
• High output level
• High input SPL capability
• No crossover distortion
• Extremely uniform polar response
• Superior common mode rejection and suppression of radio frequency interference

• ShureLockTM Rubber Isolated Shock Mount
• Protective Velveteen Pouch

Applications

Some typical applications for the KSM27 are listed below. Microphone use, however, is a matter of personal taste. The KSM27 may be used for a variety of applications other than those listed.

• Voice -- solo, background, voice-over, broadcasting
• Acoustic instruments -- such as piano, guitar, drums, percussion, strings
• Electric instruments such as guitar and bass
• Wind instruments -- brass and woodwind
• Low frequency instruments -- such as double bass, electric bass, kick drum
• Overhead miking -- drums or percussion
• Ensembles -- choral or orchestral
• Room ambiance pick-up -- guitar amplifier or drums

Both the acoustic environment and microphone placement strongly affect the sound obtained from miking a source, especially with a high resolution microphone like the KSM27. You may need to experiment with microphone placement and room treatments to achieve the best overall sound for each application.
