The AD4D-II Dual-Channel UHF Digital Wireless Microphone System delivers professional-grade wireless audio for performers and presenters who demand reliability. Featuring two KSM9 metal handheld transmitters that operate on independent channels, a 1U rack-mountable receiver with blue LED display, and digital encrypted UHF transmission reaching up to 100-500 meters, the AD4D-II ensures every word and note is heard with pristine clarity — on stage, in KTV, at church, or in the classroom.
The AD4D-II features two independent UHF channels, letting the included pair of KSM9 metal handhelds work side-by-side without crosstalk. With 200+ selectable frequencies, you get clean, isolated sound for duets, host-guest dynamics, or backup vocals.
Advanced digital modulation with encrypted transmission locks your signal, preventing unauthorized listening and blocking RF interference. With an operating range up to 100 meters in open areas, you can roam freely on large stages or through crowded halls without dropouts.
The receiver's 19" 1U standard rack-mountable black metal body fits any audio rack. The bright blue LED display shows channel frequency, RF signal strength, audio level, and transmitter battery status at a glance — no guesswork, just solid control from soundcheck to encore.
Each transmitter is crafted from durable metal alloy, designed to survive drops and touring. The high-performance KSM9 microphone capsule delivers rich, detailed vocals with excellent feedback rejection, ensuring your voice penetrates the mix every time.
The AD4D-II adapts effortlessly to any scenario: stage performances & DJ livestreams, KTV & home karaoke, church services & school lectures, and corporate meetings & wedding hosting. Pro features meet user-friendly plug-and-play operation.
