    8180M broadcast-grade full channel agile adjacent frequency modulator
     
    Introduction
    The broadcast-grade luxury Agile full-channel adjacent-frequency modulator is suitable for five-star hotels, factory dormitories, coal mines and other large-scale cable TV front-end projects.
    Features:
      1. The output has an automatic tracking filter, and the out-of-band noise is small, which is beneficial to the simultaneous use of the multi-stage, preventing the system-to-noise ratio from being deteriorated.
      2. It adopts intermediate frequency modulation, two frequency conversion methods and acoustic surface filter processing, and the out-of-band interference is small.
      3. The sound intermediate frequency, image high intermediate frequency and RF local oscillator adopt MCU phase-locking technology, and the frequency stability and accuracy are high.
      4. The output is driven by modularization and the whole function circuit of the whole machine adopts the chip process, and the whole machine has high reliability.
      5, LCD display channel, you can use the up and down buttons to set the favorite channel.
      6, easy to operate, all level adjustment control is designed on the front panel of the up and down button control, at the same time, the output level, A / V, volume, video modulation are 32-step adjustable.
      7, with IF input and output ports.
        8. The power supply part adopts high reliability and high dynamic range switching power supply.
     9, can be customized according to customer requirements for different standards.
     10. The MLS-8180M modulator has complete functions, high performance and good reliability. It is the preferred equipment for building MATV, SMATV or CATV systems.
