S-4000 true diversity professional one for four wireless conference microphone

With diversity receiving technology, the signal is more stable, the receiving distance is longer, and the application is wider.；

●Using a 2U standard chassis, the system menu is displayed on a large color screen, the content is clearer, and the working status of each channel of radio frequency and audio is displayed by independent LED lights, which is more intuitive. ；

● The four-channel volume is independently adjustable, the SQ is independently adjustable, and the IR and INFRARED frequency are independently controlled. Provides 4+2 audio output mode, which greatly facilitates users’ daily use；

●Real-time monitoring of the transmitter battery level, the system menu memory has 3 sets of stacking frequencies that can be retrieved and used, and the transmitter conference/handheld/lavalier can be mixed and matched.；

●The operating frequency of the system is set to 4 X 50 frequency points. Each channel is equipped with 50 frequency points adjustable. The system frequency range defaults to 640-690 MHZ ；

●Professional performance-level phase-locking circuit, combined with noise-locking squelch control and digital pilot technology, when the transmitter is turned off, the pilot control mutes the AF signal to suppress noise, and at the same time mutes the corresponding receiver to ensure the effective blocking of interference signals.；
