The Shure ADX2FD/B87C is a flagship handheld wireless microphone transmitter that marries a premium condenser microphone capsule with the ultimate redundancy of Axient Digital's dual-channel transmission technology. Engineered for mission-critical applications where audio quality and absolute signal integrity are non-negotiable, this system is a top choice for major broadcast events, award shows, and headline concert tours. The integrated condenser capsule is designed to deliver a smooth, detailed, and natural frequency response, capturing the full dynamic range and subtle nuances of the human voice with exceptional clarity and minimal coloration.

The "FD" designation signifies the transmitter's dual-channel capability, meaning it simultaneously broadcasts the audio on two independent radio frequencies—a primary and a backup—to a compatible dual-channel receiver. This creates a seamless, automatic fail-safe system; if interference or a dropout occurs on the primary frequency, the receiver switches to the backup transmission instantly and without any audible gap. This technology provides unparalleled wireless security for live productions where a failure is unacceptable. The transmitter integrates fully into the intelligent Axient Digital ecosystem, supporting remote control via ShowLink and advanced spectrum management.

Constructed to the highest professional standards, the transmitter features a rugged metal body, a hardened steel grille, and a clear OLED display for real-time monitoring. It is powered by a high-capacity rechargeable lithium-ion battery. The ADX2FD/B87C represents the pinnacle of handheld wireless technology, offering broadcast-quality audio capture backed by the most robust and intelligent transmission system available, making it the definitive choice for audio engineers and performers operating at the highest level.
