Designed for professional live events, corporate AV and security monitoring, the Shure AD2/K8N Pro microphone, headphone and headset transmitter delivers dependable, high-fidelity wireless audio where clarity and reliability matter most. The AD2 transmitter combines Shure’s AD series RF performance with secure encryption and a High Density (HD) mode to support maximum system channel counts in congested spectrum—ideal for houses of worship, stadiums, and surveillance/monitoring installations. With wide tuning across 470–616 MHz and an operating range up to 328.1', teams get predictable coverage across large rooms and campus environments. Power options include user-replaceable AA cells or the SB900A Li‑ion pack with dockable charging; battery run time extends to 8–9 hours for extended shifts. Durable aluminum construction, a backlit LCD, and a lockable low-profile power switch make the unit serviceable and tamper-resistant for security and physical-access control uses. Choose from multiple cardioid cartridge options to tailor vocal isolation and feedback rejection.
