LD Systems LDWS1000MW Wind / Percussion Instrument Clip Microphone

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.

The D 40 with its solid all-metal body will stand up to the hardships of night-after-night onstage use "with a smile“.
The Varimotion diaphragm deep-drawing process allows the diaphragm itself to be fine-tuned with no need for tuning resonators, leading to a quantum leap in audio performance.
The transducer is protected by a sturdy wire-mesh cap and takes extremely high sound pressure levels with ease.
An integrated stand adapter and standard H 440 mounting bracket for snare drums, tom-toms, etc. make the D 40 a highly versatile tool for use on drums, percussions, wind instruments, and guitar amps.
