Sony produced several VTRs in this one-inch format between 1963 and 1971. Models include the EV-200, EV-210, EV-300, EV-310, EV 320, EV-320F, EV-330TLV and UV-340. The 310 and 320 series were available with a remote control unit (EV 310R, EV 320R), or a Color Pack (EV 310C and EV 320C) or both (EV 310RC and 320 RC). Each machine was an improvement over the previous model. Starting with the EV-210, all the decks in the series were full color or color adaptable. The 320 series had a capstan servo. The EV-320F was a video editor with flying erase heads for superior edits. The EV-330TLV was a time lapse VTR capable of recording for up to 60 hours. The UV-340 was the last of the series and the only model that was a self-contained full color videocorder that did not require an external adapter to operate in color mode.

The videotape ranged in price in 1972 from $40 for a 32 minute tape on a plastic reel, to $70 for a 63 minute tape on a metal reel.

SONY EV 320 1" reel to reel color video tape recorder

The EV-320 represents the ultimate in color and monochrome video tape recording systems. Its special feature is capstan-servo electronic editing, which permits sequences from a variety of sources (tape, off-air, live camera, etc.) to be inserted into a prerecorded tape with perfect synchronization. These inserted portions are practically indiscernible from the original picture. In addition, using the EV-320's unique ADD feature, new scenes may be assembled into a tape without loss of sync. The capstan-servo synchronizes the EV-320 to the input signal in the playback mode. This feature allows the mixing of the EV-320's output signal with multiple cameras and with additional VTRs from a common sync source. Another unique feature of the EV-320 is its ability to automatically synchronize to a 60 Hz power source when external sync is removed. Manual switching is not necessary for this operation. The EV-320 does not require a separate sync generator for playback. In the insert mode, Audio Channel 2 is activated, so that the original sound on Channel 1 is not disturbed. The EV-320 uses one-inch video tape and conforms to standard EIA TV signal requirements. Any composite TV signal, including random interlace, 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 interchangeability between all EV Series Videocorders. The EV-320's video heads are guaranteed for a full year.

SPECIAL FEATURES
Electronic Editing
Capstan servo system provides complete insert or adding of picture on prerecorded tape without any disturbance of synchronization. The playback signal synchronizes to standard vertical sync signal input. It synchronizes to power line automatically when there is no input signal, thus making operation simple and easy. Audio Channel 2 is actuated in the insert mode, thus the original sound on Channel 1 is not disturbed

Slow and Still Playback speed is continuously variable from stop action to less than one-fifth of normal speed
Tracking Control Adjustable plus/minus 30% of rotary video head track
Audio 2 Dubbing Audio Channel 2 can be used to dub (record) audio information at a later time without erasing or disturbing the previously recorded picture
