PANASONIC MODEL NV-3120 COLOR VTR

Panasonic's Model NV-3120 is designed to the exacting specifications of the new EIAJ recommended color standard and is fully compatible with EIAJ # 1 standard for both recording and playback in black and white. Panasonic has added some features of its own to the recommended color standard: exclusive HPF (Hot Pressed Ferrite) heads for longer head life and higher picture quality, an inscribed head drum for sure interchangeability, and even a dropout compensator that all but eliminates video dropouts from s" tape. The NV-3120 is a lightweight, compact and economical 1/2" color recorder that allows even the most budget conscious institution or government agency to make the important change to color and still maintain full capability for recording and playing back tapes on the EIAJ # 1 black and white standard. Even tapes recorded in color can now be played back on black and white machines of the Panasonic 3000 series or any other #1 standard machine. The NV-3120 uses standard 5" video tape for added economy. Special features of the NV-3120 include automatic video and audio level recording controls which may also be operated manually, an audio dubbing facility, still framing, and automatic color lock control. The NV-3120 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-3120 the logical choice for almost any governmental, institutional or educational closed circuit television application.
