The Shure AD2/B87C is a premium handheld wireless transmitter cartridge assembly that combines a sophisticated wireless transmitter with a renowned condenser microphone capsule. It is designed specifically for integration with the Axient Digital wireless system, forming a complete handheld microphone solution for professional vocalists, presenters, and broadcasters. The unit merges robust RF transmission capabilities with a tailored vocal microphone sound, aiming to capture the nuanced performance of a live singer with exceptional clarity and detail. Its construction balances durability for stage use with the acoustic precision required for studio-quality reproduction in a live setting.

At the core of this transmitter is the proprietary condenser capsule, which is engineered to provide a smooth, tailored frequency response that enhances vocal presence while effectively controlling proximity effect and handling noise. The integrated digital transmitter module converts the high-fidelity analog audio signal into a secure digital data stream for transmission. This digital approach offers significant advantages in signal integrity, providing exceptional dynamic range and a noise floor that is virtually inaudible, ensuring the pure character of the source is maintained from the capsule to the receiver without added coloration or interference.

The transmitter body is ergonomically designed for comfortable handheld use over extended periods, with intuitive controls often accessed via a menu system on a built-in display. It features robust metal construction and a hardened grille to protect the sensitive internal capsule. Operating within the flexible and interference-resistant Axient Digital ecosystem, this handheld transmitter supports advanced features like ShowLink remote control for adjusting parameters from the mixing position, and compatibility with spectrum management tools that automatically find and assign the cleanest available frequencies, making it a versatile and future-proof choice for critical applications.
