  • Downloads

KEY FEATURES:

  • From 1 to 8 independent channels of signals regeneration;
  • Supported Digital Video Broadcasting standards: T, C, S and S2 (optional);
  • Reliable N-type (F or SMA as option) input and output for RF signal;
  • Grouping I / O in one (optional);
  • The powerful and stable output RF signal;
  • High reliability and stability: benefit from its highly reliable hardware and software design;
  • Remote control by IP interface;
  • Convenient management and maintenance – supports Web browser (with IP option);

Multiple protective mechanisms are included:

  • 2 reliable power supplies;
  • power failure memory recovery;
  • over‐voltage;
  • over‐load;
  • short‐circuit protection.
