Station Triax TCH

Triax TCH station

 

Short description:

  • is intended for small and medium cable networks (up to the several thousand abonents);
  • analogous and digital satellite receivers, modulators with one side (VSB) or two (DSB) poles;
  • optimal ratio price/quality;
  • simple installation and setting;
  • it is easy realized by cascading of a station, a configuration is desired for consumer;
  • modular structure up to the four digital and eight analogous modules in TCH chassis;
  • possibility of connection of decoders and transfer of an external signal to receivers-modulators;
  • full compatibility with DVD-S;
  • excellent quality of image (Signal to Noise Ratio>54 dB);
  • multi-standard: PAL(B/G, I, D/K)/SECAM(L);
  • high output level;
  • digital AFC;
  • microprocessor control and a system of control of all modules;
  • possibility of upgrade of software of digital modules through RS-232 port;
  • impulse supply source supplies up to the eight modules and LNB, the protection from short circuit is provided;
  • automatic restart at supply fault and energy independent memory for all programmable parameters;
  • mono and stereo (A2) variants of module execution;
  • HF sockets- "F" type
  • developed and made in Denmark

TCH 600:

It represents chassis with supply and control unit, RF summator, output amplifier.

  • the installation up to the eight analogous or four digital modules is possible;
  • fixing on the 19" rack or on the wall.
