Panasonic's Model NV-3130 is designed to the exacting specifications of the new EIAJ recommended color standard and is fully compatible with EIAJ 1 standard for recording and playback in black and white. The Panasonic assembly mode editing system permits synchronized, roll-free incorporation of sequences from a variety of sources onto prerecorded tape. The NV-3130 editing system allows you to achieve thoroughly professional results; the playback signal from the recorded tape is locked to the incoming sync or composite signal by the capstan servo system so that editing can be performed without loss of vertical sync. In addition, the NV-3130 features HPF* heads for longer head life and higher picture quality, an inscribed head drum for sure interchangeability, and even a dropout/noise compensator that virtually eliminates dropouts from 3" tape. The NV-3130 is a lightweight, compact and economical 3" color recorder that allows even the most budget conscious institution or government agency to make the important change to color and still maintain full capacity for recording and playing back tapes on the ElAJ^i black and white standard. Even tapes recorded in color can now be played back on black and white machines of the Panasonic NV-3000 series or any other EIAJ #1 standard machine. The NV-3130 uses standard 2" video tape for added economy. Special features include perfect electronic editing, slow motion, an audio dubbing facility, still framing, and automatic color lock control. The NV-3130 provides more than 240 lines of horizontal resolution in color and better than 300 lines in black and white. Its ease of operation and quality construction make the NV-3130 the logical choice for almost any governmental, institutional or educational closed circuit television application.
