The AD4D-II Dual-Channel UHF Digital Wireless Microphone System delivers professional-grade wireless audio for performers, presenters, and entertainers who demand reliability and clarity. At its core are two silver KSM8 dynamic metal handheld transmitters that operate simultaneously on independent channels, ensuring seamless communication for duets, interviews, or multi-speaker panels. The 1U rack-mountable receiver sports a sleek black metal chassis with a bright blue LED display, putting real-time frequency, signal, and battery data at your fingertips. Built on digital UHF technology with encrypted transmission, the system protects your audio from eavesdropping and RF interference, maintaining a rock-solid link up to 300 meters. Whether you're rocking a concert stage, hosting a KTV night, preaching at church, or lecturing at school, the AD4D-II ensures every word and note is heard with pristine clarity.
The AD4D-II features two independent UHF channels, allowing the included pair of silver KSM8 dynamic handheld transmitters to work side-by-side without crosstalk. Perfect for duets, host-guest dynamics, backup vocals, or simply having a spare mic ready on stage. Each channel maintains its own frequency and audio path, guaranteeing clean, isolated sound for every performer.
Advanced digital modulation with encrypted transmission locks your signal, preventing unauthorized listening and blocking competing RF signals. Combined with a robust operating range of up to 300 meters in open areas, you can roam freely across large stages, conference halls, or KTV lounges without fear of dropouts or signal theft—ideal for sensitive corporate events and high-profile performances.
The receiver’s 1U standard rack-mountable black metal body fits seamlessly into any existing audio rack or road case. The intuitive blue LED display shows essential info at a glance: channel frequency, RF signal strength, audio level, and transmitter battery status. No guesswork, no fumbling—just solid control from soundcheck to encore.
Each handheld transmitter is crafted from durable silver metal, designed to survive drops and the rigors of touring. The high-performance KSM8 dynamic capsule delivers rich, detailed vocals with outstanding feedback rejection and noise isolation, ensuring your voice penetrates the mix whether you're singing a power ballad, delivering a sermon, or leading a panel discussion.
The AD4D-II adapts effortlessly to any scenario: stage performances & DJ livestreams, KTV & home karaoke, church services & school lectures, and corporate meetings & wedding hosting. Its combination of professional features and user-friendly operation makes it the go-to wireless system for both seasoned audio engineers and casual users alike.
