Compact and portable, the EV-310 permits professional video tape recording of a wide variety of applications, in either full NTSC color or monochrome. The EV-310 uses one-inch video tape and conforms to standard EIA TV signal requirements. Any composite TV signal with 60 fields per second, including random interlace signals, can be recorded and played back with high resolution and excellent quality. Playing time is 60 minutes on a 2,460-foot reel of tape. Sony guarantees 100% tape inter-changeability between all EV Series Videocorders. The EV-310 features two-channel audio, editing and slow motion and stop action in the playback mode. The playback picture is continuously variable from still frame to less than one-fifth of normal speed. Audio can be dubbed on channel 2, without erasing previously recorded video. Automatic shut-off occurs when the tape reaches the end of the reel and a manual tracking feature permits any necessary adjustment to assure the optimum picture in the playback mode. Whatever your application . . . education or industrial training, in school, shop, factory or virtually any location . . . this ultra-reliable, easy-to-operate system puts you far beyond any other one-inch format VTR available, anywhere.
