JVC HR-S7600, 9500, 8600 Dynamic Drum system.

The perfect picture, from any tape. The unique TimeScan function uses JVC's original Dynamic Drum System which precisely tilts the head drum to match the tape velocity, delivering noiseless fast-motion playback in forward and reverse at speeds pf up to 9 times normal. So you can catch the day's news or breeze through long sporting events and other recorded programmes, in just a fraction of the time you'd spend otherwise. But there's more to TimeScan than a distortionless fast-motion picture - a Digital Audio Memory actually plays back the sound in the proper direction and at normal speed, even when scanning in reverse!(TimeScan audio is monaural. Sound loss may be noticeable particularly during higher speeds) So you can search for what you want based on what you hear as well as what you see. TimeScan from JVC - advanced technology for advance viewing. Sometimes makes troubles but not a problem for E17 Electronics
