The Shure ADX2FD/B87A is a premium, fully integrated handheld wireless microphone transmitter that combines the advanced Axient Digital wireless platform with the renowned BETA 87A supercardioid condenser capsule. This system represents the pinnacle of wireless microphone technology, designed for the most demanding professional applications in live touring, broadcast, and theatrical productions. The transmitter unit itself houses both the wireless electronics and the high-performance BETA 87A microphone element, providing a seamless, all-in-one solution that delivers exceptional audio clarity, extended dynamic range, and industry-leading RF performance. The Axient Digital platform operates in the robust UHF band, utilizing advanced digital modulation to provide crystal-clear audio with a wide 24-bit dynamic range and extremely low latency, ensuring perfect synchronization with other audio and video sources.

Key to the system's reliability is its sophisticated frequency coordination and management.

The system also includes Spectrum Manager software for intelligent frequency scanning and assignment, ensuring interference-free operation in the most crowded RF environments. The integrated BETA 87A capsule is a favorite among vocalists for its tailored frequency response that enhances presence and intelligibility, its tight supercardioid pattern for excellent gain before feedback, and its durable construction with a built-in spherical windscreen to control plosives.

For touring engineers, broadcasters, and production companies, the Shure ADX2FD/B87A offers an unparalleled combination of audio quality, wireless reliability, and operational control. It is built to withstand the rigors of nightly use, providing consistent, pristine vocal reproduction night after night.
