AMPEX c'e) VR-2000 Teleproduction Videotape Recorder The Ampex VR-2000 Videotape Recorder is more than an "improvement" over earlier designs; it is a totally new recorder, the result of a total evaluation of all available com- ponents, every technology involved, an evaluation of even the recording method and bandwidth. The result is a new standard of picture quality unmatched by any other tele- vision recorder in the world. The VR-2000 is being used by major networks in the U.S. for color recording and mastering. . . and by other networks throughout the world. With totally new electronic circuitry the K-Factor rating of the VR-2000 has been reduced to 1%. With the new high-band signal system, you can obtain color copies that compare with the original, monochrome dupes to the third generation. . . all with the quality of the master. A New Standard The traditional standards of bandwidth, signal-to-noise, and time base stability are inadequate for advanced tele- production work or extensive duplication. Slight "improve- ments" have been suggested, but they are only half measures. The VR-2000 represents a totally new standard of performance. Extended bandwidth providing more room for color and an adequate guard band, dramatically increased signal-to-noise ratio, greatly improved time base stability: The K- Factor Performance The K-Factor measurement technique has been widely used in Europe and Australia for a number of years. Briefly, it is a measurement of a recorder's over-all performance in terms of transient response, and is expressed as a per- centage. A theoretically perfect system would have a K-Factor of zero percent. Prior to the VR-2000, the best recorders could manage a K-Factor rating of about 5%. The VR-2000 has a K-Factor rating of 1%! The only major advancement in television recording since the introduction of the original Ampex Videotape Recorder in 1956. The VR-2000 produces multi-generation color and monochrome dupes, production flexibility so superior that it has been called "the turning point in television tape production"! Total Teleproduction Capability The picture quality put on tape by the VR-2000 is so high that color copies and monochrome copies to several gen- erations can be made, all with master-like quality. To this add the entire range of Ampex editing equipment and accessories, the time-saving, built-in test instrumentation, the 99% transistorization, and you have a recorder that's unmatched by anything else, anywhere. This is your big competitive edge. . . it's the final step toward the full realization of tape as a total teleproduction medium! Compatability With Other Recorders Though the VR-2000 is a high-band recorder, it is fully compatible with all existing low-band machines using the transverse-scan, four-head technique. Further, the VR-2000 operates on all of the world's popular line and bandwidth standards, in color and monochrome. One of two pre- selected standards may be selected by a pushbutton on the control panel. Features Totally new, in concept and production ? K-Factor of 1% ? Improved signal-to-noise ratio of 46 db or better ? New high- band signal system ? Retractable erase head reduces tape- wear ? Intersync* for synchronous operation ? Built-in test instrumentation ? 99% solid state (nuvistors or tubes are used where such use contributes to the high performance delivered by the VR-2000) ? Fully compatible with other transverse- scan, four-headed recorders ? Operates on 405, 525 and 625 line standards' ? Simple to operate, yet an "engineer's re- corder" ? Utilizes the full range of Ampex accessories for total teleproduction capability ? Prestige and profit building potential through superior quality, reliability and flexibility. Accessories AMTEC* System: Time Element Compensator for perfect pic- ture geometry. 7_.?COLORTEC* System: For faithful color recovery of both mas- ters and dubs. 3 .....44keT?RON1C EDITOR: For fast, accurate electronic splicing.
