TTV 5AB
Low Power transmitters
 
 

Composed of:

  • VAM, IF Modulator,
  • TIX V5, IF to Channel Converter

Generals. The TV transmitter TTV 5AB gives 7 Watts peak sync in continuous ervice. It is suitable for analog or digital TV broadcasting.

Broadband. Amplification circuits are broadband, so it is possible to change the transmission channel without their adjustments.

Stereo and dual sound. The Audio/Video modulator is available with dual sound facility for stereo transmissions.

High efficiency switching mode power supply guarantees high reliability, low heat generation and energy consumption.

Electronic protection assures an affordable and stable operation protecting units against major fault conditions.

Meets or exceeds all international standards for safety and electrical requirements.
