This microphone system operates in the UHF 600MHz band and features a phase-locked loop (PLL) frequency synthesizer. It uses infrared frequency and automatic synchronization to lock the transmitter frequency. Additionally, the receiver automatically scans the current environment and locks onto the best available free channels.
With a superheterodyne double conversion design, this system has a high receiver sensitivity. It includes multi-level high-performance surface acoustic wave filters, which provide excellent anti-jamming capability.
A specially designed mute circuit eliminates the impact of noise when the microphone is turned off and on. Furthermore, the microphone has a dual step-up design, which ensures that the battery life does not affect the transmit power.
In ideal conditions, the operating radius of this microphone system is 150 meters, making it suitable for use in a variety of high-demand environments.
