This UHF dual-channel wireless system features an ergonomic design with built-in auto frequency scanning to lock onto the optimal channel in real-time. It is equipped with a 1.77-inch color screen and a flywheel knob for simplified operation, enabling quick synchronization via PLL phase-locked loop and infrared frequency matching. CPU digital control combined with tone lock anti-interference technology supports 10-level volume / -60dB sensitivity adjustment and a Chinese/English interface. The 2
