ABSTRACT:
A plurality of signals picked up by a plurality of video heads are amplified by a plurality of amplifiers and then are fed to a plurality of switch circuits where the signals are alternately switched. The signals from the switch circuits are coupled by a coupling line into a continuous signal which in turn is fed to an automatic gain control circuit. The automatic gain control circuit provides at its output an FM output signal with a constant level. A color signal is taken from a portion between the coupling line and the automatic gain control circuit.
