The perfect choice to ensure continuous transmission without interruptions. The system uses two GT/GX Series transmitters and allows you to manually or automatically switch between the primary and backup transmitters when a notification is received from the on-air transmitter. For each transmitter it is possible to configure the warnings which, when activated, start the switching procedure. The system uses a control unit equipped with a large 5" LCD display, a practical multifunction knob and a few buttons. This allows the user to easily set the functions of the system and check its operating parameters at a glance. Based on the installation requirements, the system can be equipped with transmitters with different nominal power, with the only restriction of using the same RF operating frequency.
