A low band converter for recording color signals converted in low band onto a video tape media of a VTR system. The inventive converter for use in a video tape recorder is capable of converting color signals thereof in low band, so that phase and frequency of the color signals may be correctly coincident with those of a horizontal synchronization signal in the VTR, by first demodulating and next modulating by way of synthesizing the color-differential signals from the color signals. An apparatus for achieving the converter includes a burst gate generator BGPG, a pulse synthesizer, a first delay circuit, a second delay circuit, a burst amplifier, a color signal demodulator, a first modulator, a second modulator, a mixer, a first detector and a second detector, a color gain converter ACC, a video recording amplifier, a color killer suited, and a low pass filter 100.
