THE TX 1 AND TX 05 ARE REALLY INNOVATIVE FM TRANSMITTERS WITH 1000W AND 500W OUTPUT POWER RESPECTIVELY. THANKS TO THE NEW SOLUTIONS THAT OUR ENGINEERS HAVE IMPLEMENTED IN THECIRCUITRY AND TO THE COMPACT DESIGN, FOR THESE TRANSMITTERS WE HAVE ESTIMATED A 20% LONGER MTBF WITH RESPECT TO THE AVERAGE SIMILAR MODELS AVAILABLE IN THE MARKET.

THE TX 1 AND TX 05 ARE EQUIPPED WITH A MICROPROCESSOR BOARD THAT ALLOWS THE PROGRAMMING LOCALLY OR REMOTELY BY WEB (SNMP PROTOCOL). THANKS TO THE ULTIMATE ELECTRONIC COMPONENTS THAT HAVE BEEN LARGELY IMPLEMENTED IN THE DESIGN, THE OVERALL SPECIFICATIONS NOW ACHIEVED, SET TX 1 AND TX 05 AS “TOP CLASS EQUIPMENT”.
