PURPOSE:To facilitate an adjustment of a recording level by providing the 1st and the 2nd regulators to a VTR device which records a luminance, chromaticity, sound, and a pilot signals by a video head. CONSTITUTION:The FM-modulated luminance signal inputs to a terminal 15 is applied to an amplifier 23 after removing its low-frequency side band wave component by an HPF 19 is supplied to a level regulator 20 for level adjustment through a squelch circuit 21. The chromaticity, sound, and pilot signals from terminals 16-18 are summed up at a part 28 and the sum signal is passed through a squelch circuit 29 and an amplifier 30 and level-adjusted by a level regulator 31. Thus, those two level regulators are provided to facilitate the adjustment of the recording level. |
