AKG D 40 Dynamic Instrument Microphone

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.

Technical Data

NEW Wider mounting base capable of accommodating a larger range of microphone stands. Even works with the LP Claw.

Specifically engineered for drum and instrument applications, the Beta 56A's compact, pivoting design makes it the ideal choice for these applications.

Its extremely uniform supercardioid pickup pattern provides high gain before feedback and excellent rejection of unwanted noise. A built-in dynamic locking stand adapter with an integral XLR connector simplifies installation. The stand adapter keeps the microphone securely in place, even if it is struck by a drumstick. Typical Beta 56A applications include close miking of tom-toms and other percussion instruments, as well as guitar amplifiers, brass instruments, and woodwinds.

• Built-in stand adapter with dynamic locking system and XLR connector simplifies setup and provides greater flexibility
• Uniform supercardioid pattern for high gain-before-feedback and superior rejection of off-axis sound
• Compact design reduces stage clutters
• Hardened steel mesh grille resists wear and abuse
• Neodymium magnet for high signal-to-noise ratio output
• Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
• Frequency response: 50 to 16,000 Hz

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.
