笔者经反复查对《维修手册》和电路板,发现日本松下NV-33MC录像机的系统控制、多功能显示、伺服及音视频处理集成电路已具备LP功能,只是未连接使用。经试接,仅用2只电阻和一截导线,就使该机具有LP录放功能。改制后,放像时能自动识别和进入SP或LP方式并同步显示;录像时,拨动开关即可实现SP或LP方式转换并同步显示。经同松下L15录像机换放各自录制的LP方式节目带,图像的稳定性和色彩均无明显差异,只是声音略低,在特技重放时无彩色且行同步有扭曲。与附加LP装置方法相
I repeatedly check the “maintenance manual” and the circuit board and found that Japan’s Panasonic NV-33MC VCR system control, multi-function display, servo and audio-video processing integrated circuits already have LP function, but not connected to use. After the trial, only two resistors and a section of wire, so that the machine has LP recording and playback capabilities. After the system is restructured, it can automatically recognize and enter the SP or LP mode and display synchronously while playing. When recording, the toggle switch can realize the SP or LP mode conversion and the synchronous display. With the Panasonic L15 VCR playback their own way of recording LP program, the image stability and color were no significant difference, but the sound is slightly lower, there is no color in the trick playback and line synchronization has distortion. With additional LP device method phase
