High sensitivity true diversity selection circuit, each microphone signal has dual circuit reception, which can effectively reduce the occurrence of frequency interruption within the usage range and improve the usage distance;
High power transmitter design that achieves the optimal ratio between power consumption and continuous use time;
The operating frequency range of the system has been compared and optimized, adopting a narrow bandwidth design with different frequencies for the left and right channels, effectively reducing noise interference;
Specially designed for long-distance use in school playgrounds, large and medium-sized sports venues, etc., the standalone version of the system can achieve an effective usage distance of 1000 meters in the optimal usage environment without the need to install any amplifiers.
