t is hard to believe that such small, unobtrusive microphones can produce such great sound, but it's true. Available in black or white finishes, and with in-line or plate mount preamps, MX202 Microflex® Overhead condenser microphones capture high-quality sound in a compact, adjustable package. Each model features a choice of interchangeable cardioid or supercardioid condenser microphone cartridges attached to a flexible, four inch gooseneck with a 30 foot cable.

Cartridge polar pattern indicated by model number suffix:
C = Cardioid, S = Supercardioid, N = No cartridge

The APM series are digital paging microphones equipped with a condenser microphone with cardiologic characteristics, mounted on a 30 cm long gooseneck. By means of a built-in compressor / limiter, the output level of the microphone signal is constantly maintained. The status of the reproduced signal is indicated on the front panel, to ensure the speaker that the message is clear and audible in all situations. Each console has 3 standard buttons (except the APM01 which has only PTT) with pre assigned functions: PTT (Push To Talk), Select all and Clear. All other buttons can be freely programmed, using the free APM configuration software.

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
Ensemble Vocals
Piano
Strings
Room Ambience
Live Recording

Professional table microphone, high sensitivity condenser microphone capsule, flexible gooseneck, illuminated ring to indicate operating condition, and on/off switch. Perfect for all PA applications, such as conference and paging. It can be powered by battery or as by Phantom power. The base is equipped with 8 meters of cable XLRF-XLRM and XLRF-mono jack adapter.

KSM44A Multi-Pattern Dual Diaphragm Microphone Premium microphone with three polar pattern options (cardioid, omnidirectional, bidirectional).

Features

• Prethos® Advanced Preamplifier Technology: Class A, discrete, transformerless preamplifier provides  transparency, extremely fast transient response and no crossover distortion. Minimizes harmonic and intermodulation distortions.  
• Groundbreaking specifications: 4dB of self-noise and max SPL of 131 dB for a total dynamic range of 127 dB – an increase of 7 dB that defines the new standard for cleanly nuanced audio capture
• Multiple polar patterns–cardioid, omnidirectional and bidirectional–for maximum flexibility in a wide variety of recording applications
• Dual 1 inch, externally biased, ultra-thin, 2.5 μm, 24 Karat gold-layered, low mass diaphragms provide superior frequency response
• Premium electronic components and gold-plated internal and external connectors
• Subsonic filter eliminates rumble from mechanical vibration below 17 Hz.
• Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
• 3-position switchable low-frequency filter helps reduce unwanted stand vibration noise or counteract proximity effect
• Integrated three-stage "pop” protection grille reduces plosives and other breath noise
