INTER-SYNC'
TELEVISION SIGNAL SYNCHRONIZER
HOW TO GET MORE FROM YOUR AMPEX VTR
Ampex provides the perfect answer . . . Inter-Sync! Now a VTR with Inter-Sync becomes a smooth part of your production team. Use it in production as you would a camera, a film chain ... or any picture source. Inter-Sync locks the VTR to station sync . . . electronically synchronizes the recorder with any signal source — live, film, network or slides. Here's what you can do —

THREE RECORDERS? Comfortable transitions are difficult to anticipate in production. Add them later — at your leisure — with Inter-Sync! Record each production segment on tape; then put one segment on one VTR . . . another segment on second VTR. Lap dissolve for smooth transition and record on No. .3.

on all the marvels of Inter-Sync. This important optional feature is onlv one example of the continuing flow of major new developments you can always expect from Ampex — the Jack-of -one-trade . . . tape recorders.
FOR ENGINEERS ONLY:
This Ampex Model 1020 synchronizer provides both horizontal and vertical locking (line-by-line and fi ame-by-f rame) . The speed of the tvi-o-way locking process is particularly noteworthy: a total of approximately 3V{; seconds, well within the .5-second roll-in time most stations use. Vertical framing is speeded up by first using the sync pulses off the tape control track to reference to outside sync (subsequently switching to the actual vertical sync pulse). The capstan servo system resolves the inside and outside sync by smoothly adjusting the tape speed. Horizontal line-by-line locking is accomplished by precise readjustment of the head drum speed about every 5 degrees of rotation. Since the head drum rotates at 14,400 rpm, this means speed adjustments are made 94.5,000 times a minute. A unique drum servo system with push-pull action acts through the head drum motor with almost instantaneous results. Send for a 12-page Engineei'ing Department Bulletin for complete details.
ONE RECORDER? With a furniture store account, for example, pretape a series right in your studio showing the new fall line. Loan company: tape a location shot of "customer" borrowing cash. Real estate: tape a tour through a new, development home. Then, during playback with Inter-Sync, vou can wipe from tape to price slide — or lap dissolve to live announcer. No more dead air! No roll over !
Inter-Sync lets you "host " the late-late movie — and reruns — with sm-o-o-th lap-dissolve transitions between the film and your announcer on tape. No loss of mood — no abrupt changes.
TWO RECORDERS? Mix live or film with tape using key wipes or dissolves, then record on second unit. Use dissolves or special wipes between playback of two tapes. Take it from there . . .
