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.
Suggested Applications
Acoustic Guitar
Acoustic Bass
Cymbals
Brass/Woodwinds
Orchestra

Complete With Stereo Bar, Windshield's and Cradle'
The C 414 B-XL II/ST is especially useful for stereo recordings taken from the far field with the inclusion of useful and often valuable room acoustics. The matched pairs consist of two microphones that are within 1 dB to each other in sensitivity and also within 1 dB to each other in the range of 300 Hz to 8,000 Hz of the individual frequency response when used in cardioid mode and are selected from a large quantity of individual microphones using the described criteria by using a proprietary computer program.
Using this matched pair for stereo recordings utilizing various techniques will provide for a good and stable balance without frequency-dependent shifting of the stereo panorama.
The kit comes complete in an all-metal 'Soundtool' Hard Shell road case with 2 x AKG H-85 shock mounts, 2 x W414X external windscreens, an H50 stereo bar and an individually-measured chart showing the response curve of the microphone. See www.dv247.com Alternative Products and Related Products on this page for your options.
The C 414B-XLII has been carefully designed to maintain the legendary sonic character of the C 414 family while integrating new features and performance enhancements made possible by new technology. A classic microphone with a distinctive timbre especially designed for recording of solo vocals and solo instruments.
Whats the difference between the C 414B-XLII and the C 414 B XLS? The main difference between the two current C414 models lies in their frequency responses. The C 414B-XLII has a series of presence rises between 2.5 KHz and 9 KHz. This will make any recording with this microphone brighter or more sibilant than the original sound. This upper mid range boost is quite helpful on vocals and certain instruments such as classical acoustic guitars using nylon or natural strings. The C 414B XLS, see www.dv247.com Alternative Products on this page, has a very flat response that will not color the original sound which is important especially in instrumental recordings. It more suited for general use.
The microphone's 5 pickup patterns are easily selectable via an electronic switch with LED indication and offer the selection of omnidirectional, cardioid wide cardioid, hyper cardioid and figure-eight patterns. The pickup pattern selector switch utilizes a dual-color LED indicator that provides visual indication of the pattern selected and also changes from green to red to indicate if the microphone's output electronics are being overloaded. The pattern selector can also be used to "lock" the microphone's switch settings by pressing and holding it for 3 seconds. On the rear of the microphone, an electronic switch allows the selection of -6, -12 and -18 dB pre-attenuation levels which are accomplished by changing the polarization voltage to the capsule. The C 414B-XLII has switchable bass cut filters of 12 dB-per-octave at 40 Hz and 80 Hz, and a 6 dB-per-octave filter at 160 Hz for control of proximity effect. On-axis sensitivity for all patterns is 23 mV/Pa and its self-noise is an extremely low 6 dB-A.
The C 414B-XLII has a transformerless output and all-metal chassis, making it immune to electrical interference and RF from digital equipment, video monitors and wireless systems.
Features:
- High sensitivity and extremely low self noise
- Five switchable polar patterns for placement and application flexibility

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.
