UD-2271

This professional UHF wireless microphone system is engineered for live performance, conference systems, stage sound reinforcement, and commercial installations. Featuring digital-analog hybrid technology, it delivers ultra-low latency, high stability, and superior anti-interference performance for demanding audio applications.

1.Digital-Analog Hybrid Transmission · True Low-Latency Audio
Equipped with DSP processing and hybrid transmission architecture, the system ensures near-zero latency audio, high fidelity sound reproduction, 50Hz–15kHz frequency response, and <1% distortion—providing clear, natural, and stable signal performance.

2.Professional UHF Band · Strong Anti-Interference Performance
Operating within the 640–691MHz UHF professional frequency range, combined with patented single-frequency super-audio pilot control technology and intelligent mute detection, the system effectively prevents RF interference, co-channel interference, and transmitter pop noise. It supports multi-unit distributed deployment for scalable applications.

3.Dual-Channel Independent Frequencies · Enhanced Stability
Independent A/B frequency channels improve spectrum efficiency and eliminate co-channel interference, ensuring stable transmission even in complex RF environments and large-scale events.

4.Intelligent Synchronization & Professional Connectivity
Infrared (IR) synchronization enables fast and easy setup. The LED display provides real-time monitoring of frequency, RF signal, audio signal, and battery status. Dual XLR balanced outputs and TRS (A+B) outputs allow seamless integration with mixers, amplifiers, and professional audio systems.

With its low-latency transmission, robust RF stability, professional audio performance, and versatile connectivity, this wireless microphone system is an ideal solution for commercial, stage, and professional sound reinforcement applications.
