●Four-channel antenna diversity circuit design uses UHF wireless microphone dedicated frequency band, free from interference from other industrial frequencies.
●PLL digital frequency synthesis technology realizes the simultaneous use of five sets of 20 units without interfering with each other.
●Using infrared frequency synchronization technology, the transmitter is simple and convenient to operate.
●The power of the transmitter can be adjusted. Choose high power when used outdoors, and use a long distance, in classrooms or conference rooms, multi-function halls and other occasions; choose low power when used, which can reduce interference and save battery power.
●Adopt data pilot frequency control technology to effectively prevent other radio frequency interference and the impact sound of transmitter switching machine.
●The transmitter is powered by 2 1.5VIAA batteries (conference base), which has a long battery life and is more convenient for maintenance.
●With balanced and unbalanced audio output, it is convenient to connect with various audio equipment.
●The receiver can display the working parameters of the transmitter for easy monitoring.
●The transmitter is made of high-strength alloy material, which is durable.
●Super strong anti-cell phone interference technology
●Working distance: 70 meters in a straight line without obstacles.
