Generals. The TV transmitter TTI 3000AB gives 3000 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.

Modular construction. The amplifiers are assembled by means of independent modules to improve the redundancy. More, RF and power supply racks are easily pluggable and interchangeable in case of servicing.

Continous operation. The coupling architecture between stages keeps always reduced power operation even in case of fault in one stage.

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.
