GENERAL DESCRIPTION
The ShureR 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
SCardioid polar pattern – the most commonly used pattern for both studio and
live applications
S1 inch, externally biased, ultra-thin, 2.5 µm, 24 Karat gold-layered, low
mass, MylarR diaphragm provides superior transient response
SClass A, discrete, transformerless pr eamplifier for transpar ency, extremely fast
transient response a nd no crossover distortion, whi le minimizing har monic and
intermodulation distor tions
SPremium electronic components and gold-plated internal and external
connectors
SSubsonic filter eliminates rumble from mechanical vibration below 17 Hz
SSwitchable 15 dB pad f or handling extremely high sound press ure levels (SPLs )
S3-position switchable low-frequency filter helps reduce unwanted back-
ground noise or counteract proximity effect
SIntegrated three-stage “pop” protection grille reduces plosives and other
breath noise
SInternal shock mount reduces handling and stand noise
