    Description

    Description
    Using the international advanced Ambient Noise Cancellation (ANC) environmental noise elimination technology,
    Built-in automatic identification module noise, utmost reduce the ambient noise.
    Multistage dynamic noise reduction processing, voice clear, low noise, better noise reduction degree
    AGC automatic gain circuit make more balanced sound amplitude of the output amplitude; sound playback affection is more smooth and comfortable.
    Use 3 core 0.5 mm 3 km RVVP shielded cable transmission distortion.
    Monitor head built-in lightning protection, power supply polarity reversal.
    Integrated import front audio amplifier, monitor head driven directly active speakers, DVR.
    Apply to the courts, interrogation, cell, divisions, police station, the telecommunication and bank vault, etc.
    Comply with the CE, FCC, and ROHS standard.
