OK-9500 Wireless Microphone for Large Stage Performance

True‑diversity System / High‑Power Performance Version / Ultra‑Long‑Range Microphone. Adopts our self‑developed proprietary high‑sensitivity true‑diversity signal‑selecting circuit. Each microphone signal is received by dual circuits, which effectively reduces drop‑outs within operating range and extends working distance.
High‑power transmitter design achieves an optimal balance between power consumption and continuous working time.
The system operating frequency range is optimized through comparative testing. Narrow‑band design with different frequencies for left and right channels effectively suppresses noise interference from out‑of‑band signals.
Engineered for long‑distance speech scenarios such as school playgrounds and large‑medium‑sized stadiums. Under optimal conditions, the single‑unit system delivers an effective operating distance up to 1000 meters without additional amplifiers.
Supports simultaneous operation of up to 2 sets of systems.
