ABSTRACT OF THE DISCLOSURE In a system for recording or playing back a television signal, composed of a picture carrier which is FM modulated with a video signal and an audio carrier which is modulated with an LF audio signal, recorded along oblique tracks on a magnetic tape, the system including two playback heads which alternately scan successive tracks, a keying pulse is generated in time coincidence with each moment when scanning switches from one head to the other. The keying pulse can be used during playback to increase the gain of an amplifier conducting the audio carrier to an extent to cause the amplifier to generate output oscillations at a selected frequency. Alternatively, the keying pulse can be used during recording to temporarily increase the amplitude of the audio carrier. - 1
