近来,国内不少电教单位都用上了由上海无线电三厂组装的日本JVC公司HR-D210EE型VHS录像机,该机采用了HR电路,图像较清晰,缺点是原机上无通用的BNC型和phono型视音频输入输出插孔,而是装有一个梯形21蕊插座作为视音频输入输出用,但没有提供与其相配的插头,市面上也没有出售,使用户难以用视音频录放像。笔者通过下面的简单方法给该机加装了两个BNC型插座和两个莲花插座,作视音频输入输出用,而对原机各项性能无任何影响,方便了使用。
Recently, many domestic audio-visual units have spent on the assembly of the Shanghai Radio Factory JVC Japan HR-D210EE-type VHS VCR, the machine uses a HR circuit, the image is more clear, the disadvantage is the original machine without the universal BNC type and phono Type video and audio input and output jacks, but equipped with a trapezoidal 21-core socket for video and audio input and output, but did not provide matching plug, the market is not sold, making it difficult for users to use video and audio recording. The author through the following simple method to the aircraft installed two BNC socket and two Lotus socket for audio and video input and output, and the original machine without any impact on the performance, convenient use.
