UHF Predictive-Diversity Wireless Microphone System
TD-502
■ Prevent crosstalk. Each channel has a unique ID code, which can prevent any interference source from entering the receiver
■ With the world's advanced ACT (automatic channel locking) function, it can quickly and accurately automatically lock the working frequency of the receiver;
■ The shell is made of aluminum alloy, with professional quality of being able to withstand falling without failure;
■ Special color tailgate channel identification in 8 colors;
■ High quality, clear and bright supercardioid directional microphone core with high fax, wide sound range, high dynamic range;
■ CPU control;
■ Phase locked loop frequency synthesis technology;
■ Real diversity dual reception technology;
■ Large screen dynamic LCD display, which can dynamically display AF, RF levels and channel conversion;
■ 200 channels are adjustable, and multiple sets can be used simultaneously without interference;
■ The panel can set the working distance, display mode and panel lock function.
