BEYERDYNAMIC M99 HYPERCARDIOID DYNAMIC MICROPHONE

APPLICATIONS

A special microphone and almost an ?instrument? in its own right designed to
create the kind of sound beyond the possibilities of regular signal processing.
The massive dynamic element can enhance the dynamics of instruments when
close miked and add depth to expressive vocalists.

FEATURES:
? Dynamic, hypercardioid polar response
? Switchable presence emphasis and equalisation
? Integrated elastic suspension
? Rugged construction

SPECIFICATIONS: 
Dynamic
Frequency response 30 - 18,000 Hz
Polar pattern Hypercardioid

The Shure KSM137 is an end-address condenser microphone with a cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments.

Features

• A highly consistent cardioid polar pattern
• Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar? diaphragm for superior transient response
• Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion
• Premium electronic components, including gold-plated internal and external connectors
• Subsonic filter eliminates low frequency rumble (less than 17 Hz) caused by mechanical vibration
• Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
• Three-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs)
• Three-position switchable low-frequency filter reduces background noise and counteracts proximity effect

Performance Characteristics

• Extended frequency response
• Low self noise
• Exceptional reproduction of low-frequency sounds
• Can withstand high sound pressure levels (SPL)
• High output level
• No crossover distortion
• Uniform polar response
• Superior common mode rejection and suppression of radio frequency interference

APPLICATIONS

Some typical applications for the KSM137 are listed below. Microphone use, however, is a matter of personal taste. The KSM137 may be used for a variety of applications other than those listed.

• Acoustic instruments -- such as piano, guitar, drums, percussion, strings
• 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. You may need to experiment with microphone placement and room treatments to achieve the best overall sound for each application.
