Low Power transmitters
Composed of:
-
VAM, IF Modulator,
-
TIX I10, IF to Channel Converter
Generals. The TV transmitter TTI 10AB gives 10 Watts peak sync in continuous service. 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.
