The Shure ADX2FD/K11 is a handheld wireless microphone transmitter designed for Axient® Digital Wireless Systems, delivering unmatched audio quality, RF stability, and advanced control features. Outfitted with the KSM11 cardioid condenser capsule, it captures vocals with full-bodied lows, clear mids, and smooth high-end detail, making it ideal for demanding live performances and broadcast applications.
With Frequency Diversity, the ADX2FD/K11 is capable of transmitting RF signals on two discrete carriers for maximum signal stability, while wide tuning up to 184 MHz and High Density mode ensure optimal channel count and robust coverage in even the most challenging RF environments. Optional 50 mW High Power mode provides additional range and reliability when needed.
Engineered for durability and touring environments, the ADX2FD/K11 features a lightweight, moisture-resistant metal case in black or nickel finish. It offers up to 6.5 hours of runtime with the included SB920A rechargeable battery when transmitting on dual carriers, or up to 9 hours when using a single carrier. External contacts enable convenient docked charging, and an optional fully covered radome provides additional protection.
ShowLink® remote control allows real-time adjustments to parameters directly from the booth, while automatic interference avoidance ensures consistent, uninterrupted performance. Two selectable transmission modes—Standard and High Density—further expand flexibility for large-scale productions. For added peace of mind, the ADX2FD/K11 also supports secure, encryption-enabled transmission.
Perfectly blending premium vocal performance with Shure’s most advanced wireless technology, the ADX2FD/K11 redefines professional handheld wireless microphones.
