Designed for high sensitivity transmission and stable anti-interference. This UHF Dual-Channel series utilizes quartz crystal oscillating mode, providing pre-selected frequencies between 460-970MHz. With two channels and two transmitters on different frequencies, it allows for up to 10 sets to operate simultaneously at the same site, making it ideal for public places like campuses and hospitals.
Featuring ± 0.0005% ultra-high frequency accuracy combined with PLL phase-locked loop control. This technology eliminates frequency deviation problems with a maximum deviation of ± 45KHz, ensuring zero frequency interruption or sound delay during use.
In open environments, the transmission distance reaches 60-80 meters. The dynamic directional microphone unit and FM modulation provide a frequency response of 45Hz~18KHz (± 3dB) with total harmonic distortion under 0.4%, ensuring clear and delicate vocal and instrument reproduction.
The system is optimized for performance and energy efficiency. High-quality battery integration offers higher energy density and longer battery life. This reduces environmental pollution from disposable batteries while providing stable voltage and current, effectively reducing noise and distortion caused by unstable power sources.
