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.

- Cardioid polar pattern for multiplicity of vocal and instrument applications
The earlier model C 3000 has had a large fan club in the project studio and home recording worlds for years. For the new C 3000 B, AKG designed a special 1-inch large-diaphragm transducer that closely approximates the vibration performance of top-class studio microphones, but can be made at much lower cost.
Due to its surface area and special capsule tuning, the C 3000 B large-diaphragm transducer produces an exceptionally pleasing, smooth sound. Unlike in the C 3000, the switchable 10-dB preattenuation pad immediately follows the transducer in the signal path, thus increasing the C 3000 B\'s SPL capability by a true 10 dB. Loud sound sources are therefore no problem.
An acoustically optimized cardioid polar pattern makes the C 3000 B an excellent choice for both recording and live sound applications where high gain before feedback is paramount.
