And high image quality. The U standard video tape recorder has a rotary erase head and a blanking switch, and also has a capstan servo and a reel servo system. For this reason, each cut is temporarily recorded in the tape cassette in a random order, and a desired cut is selectively reproduced from the previously recorded tape cassette to be recorded in order in the master tape cassette as an assembly edited and recorded master. It is possible to perform high-quality and high-accuracy editing such as insert editing for recording a reproduction signal from an already recorded tape cassette at an intermediate position of the tape cassette.

Conventionally, after remotely operating the video tape recorder that plays back the recorded cassette tape and the video tape recorder that edits and records the master cassette tape, select and register the editing positions for the recorded cassette tape and the master cassette tape. There is an automatic editing control device for automatically editing and recording a reproduction signal at a registered position of an already recorded cassette tape at a registered position of a master cassette tape.

Here, when selecting the editing position of each of the recorded cassette tape and the master cassette tape, the editing position is determined by looking at each monitor image, and the editing position is determined by listening to each monitor sound. There is. In this U-standard video tape recorder, the audio track is recorded along the longitudinal direction of the tape separately from the video track. For this reason, when the editing position is determined by the monitor sound, it is necessary to adjust the volume according to the tape running speed. However, the volume of the monitor sound cannot be adjusted by the conventional automatic editing control device. In addition, the volume of the monitor receiver arranged apart from the automatic editing control device has to be adjusted, which has a drawback of poor operability.
