Advanced automatic frequency technology. If the frequency of transmitter and receiver are mess, you can press conference unit to search the frequency of transmitter and adjust the frequency same as transmitter’s
? Adopt UHF super high frequency range; Less interference than traditional VHF and more reliable.
? DPLL synthesis of digital phase locked loop multi-channel frequency synthesizer. In 50MHz frequency bandwidth, 250KHz channel apart, it provide 200 channels. Many sets machine can be used simultaneously.
? Advanced automatic frequency technology. If the frequency of transmitter and receiver are mess, you can press conference unit to search the frequency of transmitter and adjust the frequency same as transmitter's.
? Special receiving sensitivity adjustable function which is used to improve anti-interference capacity or increase receiving distance.
? Premium display screen. Can check working status of system controller and units clearly.
? The range can be 60M in ideal environment.
? Free discussion working mode.
? Using 20pcs wireless conference units in same space and same frequency range; If the frequency is not setup properly, it will causes intermodulation interference.
? Aluminium alloy case. The material has ROHS certification.
? Adopts 1U international standard design which can be installed in 19inch case.
