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 extend- ed frequency response specially tailored for vocal tracking and instrument recording.
OPERATING THE KSM27 Mounting Use the shock mount to secure the KSM27 to a floor or boom stand by threading the shock mount onto the microphone stand and inserting/threading the microphone into the shock mount.
FIGURE 2. LOW FREQUENCY RESPONSES Setting Attenuation The attenuation switch on the back of the KSM27 reduces the signal level from the cartridge by 15 dB without altering the frequency response. This can prevent ex- tremely high SPLs (ie. close miked drums and guitar cabinets) from overloading the microphone.

Integral Pop Filter The KSM27 grille consists of 3 separate mesh layers that act as an integral pop filter which helps reduce wind and breath noise. Depending on the performer, an external pop-protection screen or windscreen (See Figure 3) may be necessary when close-miking vocalists.

Meets applicable tests and performance criteria found in European Professional Audio Products EMC Standard EN 55103 (1996); Part 1 (Emissions) and Part 2 (Immunity). The KSM27 is intended for use in environments E1 (residential) and E2 (Light Industrial) as defined in European standard EN 55103. EMC conformance is based on the use of shielded interconnecting cable.
