Two-band modulator with microprocessor controlThe output channel is selected using two buttons (visible when the lid is opened) and its number, like any parameter described below, the value of which can be changed, is displayed on the LED displayThe channel number and the values of other parameters are saved in non-volatile memoryThe use of the quartz stabilization system (PLL) provides almost zero frequency errorModulators can be combined They also allow summation of the modulated signal with the terrestrial TV signalIt is possible to protect the modulator against unauthorized accessIt should be noted that compared to previous series of modulators, Terra has implemented more variants of the PAL system
