BETA 98AD/C Miniature Cardioid Condenser Drum Microphone
BETA 98A/C Miniature Cardioid Condenser Microphone
The Shure Beta 98A is a precision-engineered compact, high-output miniature condenser microphone for professional sound reinforcement and studio recording. An extremely uniform cardioid polar pattern provides excellent gain-before-feedback and off-axis rejection of unwanted noise.
Both Beta 98A configurations feature high sound pressure level capability (SPL). Beta 98AD/C includes A98D drum mount with flexible gooseneck that makes it an essential, accurate choice for toms, snares, and percussion. Beta 98A/C is recommended for a variety of acoustic or amplified instruments including drums, piano, reed, wind, and strings.

A high performance mini-condenser for sound reinforcement and recording. Great for instruments or drums. The ultra-uniform pickup pattern provides high gain before feedback and excellent rejection of unwanted noise.
Other features include:
- Mew A98D flexible drum mount
- SPL handling to 160dB
- frequency response of 20 to 20,000Hz and included preamplifier
- shock mount and windscreen
| Optimized for low-frequency bass punch/high-power SPL handling. Designed for kick drum.
The Shure BETA®52A is a high output dynamic microphone with a tailored frequency response designed specifically for kick drums and other bass instruments. It provides superb attack and "punch“, and delivers studio quality sound even at extremely high sound pressure levels.
The Beta 52A features a modified supercardioid pattern throughout its frequency range to insure high gain-before-feedback and excellent rejection of unwanted sound. A built in dynamic locking stand adapter with an integral XLR connector simplifies installation, particularly if the microphone is to be placed inside a kick drum. The stand adapter keeps the microphone position fixed and resists slipping, even when subjected to sharp blows and strong vibrations. A hardened steel mesh grille protects the Beta 52A from the abuse and wear associated with touring.
Features
- Frequency response shaped specifically for kick drums and bass instruments
- Built–in dynamic locking stand adapter with integral XLR connector simplifies setup, especially inside a kick drum
- Studio quality performance, even at extremely high sound pressure levels
- Supercardioid pattern for high gain before feedback and superior rejection of unwanted noise
- Hardened steel mesh grille that resists wear and abuse
- Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
- Neodymium magnet for high signal–to–noise ratio output
- Low sensitivity to varying load impedance
- Legendary Shure quality and reliability

| The Shure KSM141 is an end-addressed condenser microphone with mechanically switching dual polar patterns (cardioid and omnidirectional). Designed for studio use, yet rugged enough for live applications, the KSM141 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 mechanical polar pattern switch for highly consistent cardioid and true omnidirectional polar patterns. Provides flexibility in a wide variety of recording applications
- 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
- Three-position switchable pad (0 dB, 15 dB, and 25 dB) 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 to reduce background noise and counteract 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 KSM141 are listed below. Microphone use, however, is a matter of personal taste. The KSM141 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.
