1: Using UHF610 to 670 frequency bands effectively avoids interference bands and has strong anti-interference performance.
2: Using advanced PLL phase-locked loop technology, coupled with high-precision quartz crystal and 32-bit microcomputer microcontroller control, the frequency stability is extremely high.
3: Equipped with infrared frequency matching (synchronous transmission and reception frequency), greatly improving the convenience of product use.
4: Equipped with advanced patented RDS digital pilot function, each cat has a different random ID code to eliminate interference and crosstalk.
5: An automatic mute and impact cancellation circuit with three logical relationships. Effectively avoiding the impact sound of power on/off and noise caused by poor signal quality.
6: Equipped with adjustable transmission power and adjustable reception sensitivity (noise reduction depth), the combination of the two can effectively and conveniently control the reception distance.
7: Equipped with one click automatic message selection function, it intelligently and quickly selects clean channels without interference, greatly simplifying the debugging workload in engineering installation and improving work efficiency.
8: The transmitter adopts a dual boost circuit design to ensure that the emission performance will not be affected when the battery voltage drops.
9: The receiver display screen can reflect real-time information such as the battery level of the transmitter.
10: A concise operating interface with minimal adjustable components can completely avoid malfunctions caused by misoperation.
11: High pickup sensitivity and excellent sound quality make your speech or singing effortless and effortless.
12: Can be used by multiple stacked machines without interference or frequency hopping.
13: The use distance is long and can be adjusted arbitrarily. The large dual LCD display screen, with a beautiful and elegant appearance design, is particularly suitable for professional KT V venues, schools, and performances.
