2023-04-03 deken 118


  • Adopt 2U standard chassis. System menu color large screen display, true diversity receiver.

  • Adopting diversity receiving technology, the signal is more stable, the receiving distance is farther, and the application is wider.

  • Four-channel independent frequency selection system, can be greater to reduce the occurrence of broken frequency.

  • Independent LED lights show the working status of each channel RF and audio, more intuitive.

  • Four-channel volume independently adjustable, SQ independently adjustable.

  • IR infrared frequency matching independent control.

  • Provide 4+2 audio output mode, greatly facilitate the user's daily use.

  • RF transmission frequency range: 640-690MHz.

  • Working range: 50 meters under typical conditions and 200 meters at outdoor straight-line distance (the actual working range depends on the absorption, reflection and interference of RF signal).

  • The working frequency of the system is set to 4x100 frequency points, and each channel is equipped with 100 frequency points adjustable.

  • Noise lock squelch control + tone code navigation lock squelch control.

  • Audio dynamic expansion and automatic level control circuit.
