■ Four channel receiving, UHF wireless microphone special band design, free from interference of other industrial frequencies.
■ PLL digital frequency synthesis technology provides up to 200 selected working channels to realize the simultaneous use of multiple machines.
■ Adopt infrared frequency synchronization technology, the transmitter is easy to operate.
■ The power of the transmitter can be adjusted. When it is used outdoors, choose high power and long distance. It is used in classrooms or conference rooms, multi-function halls and other occasions; Select low power when using, which can reduce interference and save battery power.
■ Data pilot control technology is adopted to effectively prevent other RF interference and the impact sound of transmitter on and off.
■ The transmitter is powered by two 1.5v/aa batteries, which has long service time and convenient 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.
■ Working distance: 100m.
