Product Overview
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 KSM9 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.
Key Features & Benefits
🔹 Dual-Channel UHF Operation – Two Mics, One Receiver, Zero Interference
The AD4D-II features two independent UHF channels, allowing the included pair of KSM9 metal 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.
🔹 Digital Encryption & Long-Range Stability – Your Audio Stays Private and Solid
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 100m-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.
🔹 1U Rack Receiver with Blue LED Display – Command Center in a Compact Chassis
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.
🔹 Robust Metal Handhelds with KSM9 Capsules – Built for the Stage and the Long Haul
Each handheld transmitter is crafted from durable metal, designed to survive drops and the rigors of touring. The high-performance KSM9 microphone capsule delivers rich, detailed vocals with excellent feedback rejection, ensuring your voice penetrates the mix whether you're singing a power ballad, delivering a sermon, or leading a panel discussion.
🔹 From Concert Halls to Living Rooms – One System, Endless Possibilities
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.
