Power Cutback Unit
The Power Cutback Unit allows for the reduction in transmitter power required for FCC approved pre-sunrise or post-sunset power levels when the transmitter power could not be internally reduced to the desired power level without inducing excessive audio distortion.The power cutback unit consists of a resistive power divider network coupled into an L-C network to match the output impedance to the desired value. Up to three selectable reduced power levels are available in addition to a bypass mode which directly links the transmitter to the antenna system. The units are pre-tuned for 50 ohms input and output in all cutback modes. Rack Mountable Controllers with failsafe transmitter switching and both remote and local control of selected power levels can be supplied.
