The Sony Videocorder model AV-8650 is a highly-advanced color video tape recorder designed especially for use with Sony video cameras and monitors, and will record video signals that conform to EIA monochrome or NTSC color standards. The AV-8650 provides color/monochrome video and audio recording and playback. Full editing capability simplifies professional tape production.

FEATURES
Tapes are fully interchangeable so that a tape recorded on any Sony AV-Series Videocorder can be played back on the AV-8650. However high density tapes recorded on the AV-8650 are only interchangeable on other high density tape machines such as other AV-8650 Videocorders.

Both regular tape and high density tape can be used. When using high density tape, particularly in editing, the high quality picture can be obtained. The TAPE SELECT switch adapts the Videocorder to the type of tape.

Video and audio signals can be inserted into or assembled onto a prerecorded tape. The rotary erase head and vertical
interval switcher assures smooth insertion and assembly

A converted sub-carrier direct recording system and dropout compensator are employed.

External sync may be checked during playback without dis12 connecting the signal source.

The capstan servo system monitors and controls the tape speed, assuring precise editing and a stable picture with minimum fitter.

Video recording level can be controlled automatically or manually by the setting of the VIDEO AUTO/MANUAL
button. Audio LIMITER for recording is selected with the AUDIO LIMITER ON/OFF button.

A still playback picture can be obtained by setting the Function selector to PAUSE/STILL. Slow motion tape speed is adjustable by means of the SLOW SPEED control.

Tracking and skew conditions are manually controlled in the playback mode. A level meter indicates tracking condition.
