    • A brand new audio circuit architecture, with delicate high tones,     strong mid to low fr equencies , and perfect detail expression
    • The new concept of digital pilot technology completely solves the phenomenon of cross frequency interference and never causes cross frequency interference.
    • Automatic search for interference free channels, making installation more convenient.
    • The maximum output volume can be freely limited, with a wider range of applications
    • UHF frequency band, phase-locked loop (PLL) frequency synthesis
    • 80 x 2 channels, with channel spacing of 250KHz.
    • Ultra heterodyne secondary frequency conversion design with extremely high receiving sensitivity
    • The RF part adopts multi-level high-performance dielectric filters, which have excellent anti-interference ability.
    • The first intermediate frequency uses a sound meter filter, and the second intermediate frequency uses a three-level ceramic filter to improve anti-interference ability
    • Specially designed mute circuit that completely eliminates the impact noise of microphone opening and closing
    • The microphone uses EasyBuy's No. 5 battery, with a battery life of 8-12 hours
    • The microphone adopts a unique boost design, and the decrease in battery level does not affect the overall performance of the transmitter.
    • Ideal operating radius of 80 meters , suitable for various requirements
    • Equipped with infrared automatic frequency matching function, it can quickly synchronize the microphone to the working channel of the receiver
