UHF Predictive-Diversity Wireless Microphone System
ACT-1490
■ With the world's advanced ACT (automatic channel locking) function, it can quickly search for channels that are not used by users and are not interfered with
■ The shell is made of aluminum alloy, with professional quality of being able to withstand falling without failure;
■ Super anti-interference ability, which can effectively suppress noise interference and interference of the same frequency brought by the outside
■ High quality, clear and bright supercardioid directional microphone core with high fax, wide sound range, high dynamic range;
■ Phase locked loop frequency synthesis technology;
■ Large screen dynamic LCD display, which can dynamically display AF, RF levels and channel conversion;
■ 100 channels are adjustable, multiple sets can be used simultaneously without interference;
■ The panel can set the working distance, display mode and panel lock function.
■ Diversity technology;
■ Special color tailgate channel identification with multiple colors;
