松下AG—5700编辑系统由两台AG—5700型编辑录相机、一台AG—A570型编控器及两台监视器和若干连接线组成。这套编辑系统高低带兼容,可组合插入编辑,接点干净准确,价格相对较低,因而在中小电视台尤其是有线电视台得到广泛运用。 但笔者在实践中发现必须对其连接进行改进。按照松下AG—A570编控器的说明书所示(如图〈1〉),放机的视音信号要通过其监视器输出到录机,放机和录机可以在各自的监视器上通过AG—A570完成各自的编辑操作。 这种连接的缺点是很明显的。〈1〉放机的视音信号经过监视器后必将受到一定的损耗,录机得到的信号会因放机的监视器的优劣受到或大或小的影
Panasonic AG-5700 editing system consists of two AG-5700-type editing camera, an AG-A570-type controller and two monitors and a number of connecting lines. The editing system with high and low band, can be inserted into the combination of editing, contact clean and accurate, the price is relatively low, which in small and medium-sized television stations, especially cable television has been widely used. However, in practice, I found that it must improve its connection. According to Panasonic AG-A570 controller manual (shown in Figure <1>), put the machine’s video and audio signals through its monitor output to the recorder, put machine and recorder can be on their respective monitors through the AG -A570 Complete their respective edits. The disadvantage of this connection is obvious. <1> Put the video and audio signals through the monitor will be subject to certain loss, video recorder signal will be due to the pros and cons of the monitor on the machine by large or small shadow
