• General. The cavity tube power amplifiers TAV & TAU series are designed to operate on IV/V Band (TAU 5000) and III Band ( TAV 5000) as linear amplifiers to combined vision/sound transmission.
• 5000 W output power continous ratin are guaranteed by redoundancy of all parts of this series amplifiers.
• 175 W exciting are necessary to obta full output power.
• High efficiency cavities employed a used by the most important world-wide producers and tested by many functioning years on the major broadcasting stations. These cavities are the best to strenght, reliability, parameters constancy along the time.
• Long life tube. Siemens tetrodes RS 2022CL (TAV 5000T) and RS 1034 (TAU 5000T) are used with reduce power,- this guarantees a long average life also in not ideal conditions.
• Notch filters available with many ca ties and several configurations, guarantee spectral clearness over international standards limits (CCIR/FCC/DOC).
• Electronic protections assure a affordable and stable operation protecting units against major fault conditions.
• Internal logic control unit and interface gates with driving stages are compatible with major international standards.
• Operator's safety is protected by active and passive devices according to international standards.
• A multipurpose instrument on the front pannel allows the operator to monitor the main operation parameters.
• Forced air cooling. An overdimensioned centrifugal fan and a regenerable a filter, guarantee amplifier regular functioning even with hard climatic and ambiental conditions.
• Meets or exceeds international standards for safety and electrical specifications.
