Description Features Technical Parameter
16 in 1 modulator, It will be up to 16 audio and video signals into a road with 16 TV channels RF signals. The product is widely used in hotels, hospitals, schools, electronic teaching, factories, security monitoring, VOD video on demand and other places of entertainment, especially for digital TV analog conversion, and centralized monitoring system.
 
  • The modulation circuit adopts the mainstream regulation chip and the single chip microcomputer control, which is stable and reliable.
  • The modulation circuit of each channel is completely independent, and the channel configuration is very flexible and convenient.
  • The power supply has a large amount of redundancy and can work continuously and stably for many years.
  • The relevant debugging of the cable TV transmission equipment has been completed before leaving the factory.
  • Input HDMI signal can work, can be installed and constructed by non-professionals.
  • Multi-channel modulators are integrated for installation, compact structure, no need to set up a special computer room.
