1. The modulation circuit adopts the mainstream modulation chip and microcontroller control, which is stable and reliable.
2. The modulation circuits of each channel are completely independent, and the channel configuration is very flexible and convenient.
3. The power supply has a large margin of redundancy and can work continuously and stably throughout the year.
4. The relevant debugging of the cable TV transmission equipment has been completed before leaving the factory. It is free of debugging on site and can work by inputting AV signals. It can be installed and constructed by non professional personnel.
5. The integrated installation of multiple modulators has a compact structure and does not require a dedicated computer room.
