Warum ist dieser Prospekt aus 1961 so interessant ?

1956 photograph shows Charles P. Ginsburg (left), the man most responsible for the design of the VTR, with Phillip L. Gundy, Ampex Vice President, at the introduction on Ampex television tape recorder at N.A.B. on April 14th of that year. Ginsburg has since received both the Vladimir Zworykin Award and the Valdemar Poulsen Gold Medal in recognition of his work.

Nach der ersten AMPEX VRX 1000 und dem folgenden Boom wurde ja in den Ampex Labors weiter entwickelt. Die NTSC Farbe zeichnet sich als ein Muß ab. Und die Expansion ins Ausland wurde nicht mehr als ein gequältes überhaupt nicht notwendiges Übel angesehen, sondern ernsthaft verfolgt.

Während die allererste AMPEX Maschine für Deutschland fast schon im Werk in Redwood "gestohlen" werden mußte (ist etwas leicht überspitzt !), Siemens baute die auf 220 Volt und 50Hz um, merkten die Ampexer, daß sich da weltweit ein riesiger Markt auftat. Auch zahlten die internationalen Kunden auch jeden Preis, es gab ja nichts Vergleichbares.
Die Japaner waren technologisch und wirtschaftlich noch nicht so weit und die Quadruplex Technik war ja sowieso weltweit für Ampex patentiert.

Auf der letzten Seite sind alle Ampex Modelle zu sehen.

Ein für uns seltenes Bild finden wir auf der letzten Innenseite des Prospektes, die gesamte Ampex Familie von Anfang an bis 1961. Unser Mr. Ampex, Tom Marjanovic, hatte mir das zwar alles mal erzählt, aber es war viel zu viel zum Merken und er wollte es ganz bestimmt aufschreiben. Doch dazu kam er nicht mehr.

THE NEW VR-1002 UPRIGHT MODEL

Broadcast practices dictated its design ... advanced Ampex engineering dictated its improved operating capacity.

AMPEX'S unique and ever-growing knowledge of broadcast operational requirements ... and advanced engineering refinements make the VR-1002 a significant advancement over all previous upright models ... to provide simplified operation and maintenance, improved picture quality, and greater dependability than ever before.

In 1956, Ampex introduced the first commercially successful Videotape Television Recorder. Its performance, quality and reliability immediately established it ... and each succeeding Ampex model ... as basic standards of excellence in television tape recording.

Now, on the 5th anniversary of this introduction, Ampex presents an improved, simplified Videotape Television Recorder, the VR-1002, uniting proven, basic features with major innovations and refinements in operating controls and circuitry.

The VR-1002 delivers new quality in the sharpest, brightest picture in television today, with new ease and flexibility in operation and maintenance, and the assurance of even greater reliability.

Like its predecessor, the Ampex VR-1002 takes its place as the new standard of excellence in upright VTR's around the world.

Improved upright design with simplified operating features

Improved upright design with simplified operating features are the most important overall developments in the new VR-1002. It is more efficient and considerably simplified for
set-up, operation and maintenance. This simplification means both initial and operating savings for the owner, without detracting from the operational effectiveness.

One of the major Ampex advancements is the AFC Modulator. Carrier frequency and deviation can be set up for two
standards in less than a minute, without use of external test equipment.

Re-setting and checking of carrier frequency need be done as infrequently as once a week rather than several times a day, because the carrier is continually under automatic control and is monitored by a meter indicating potential drift from proper frequency.

The new design places all meters required for normal operation within the control area, with control knobs placed adjacent to their respective meters.

The unitized design of the new Mark III head permits preselection and precise matching of the individual transducers to minimize geometric picture distortion
and improve performance characteristics.

Unitized construction also maintains high signal-to-noise ratio and noise banding is accurately controlled over the entire gray scale of the TV picture, assuring maximum precision and picture quality in the interchange of TV tapes.

Although it incorporates important electronic refinements, this VTR affords complete interchangeability with all other Ampex television tape recorders in operation throughout the world.

THE NEW VR-1002 UPRIGHT MODEL

gives today's broadcasters the quality features they want most.

Ampex's unique experience covers more than half a decade of equipping broadcasters, networks and production companies with more than 800 Videotape Television Recorders.

Applying this unparalleled experience and knowledge of operational requirements to the design of the VR-1002, Ampex offers the broadcaster new, refined features best suited to today's needs. This simplification affords the ultimate in convenience, reliability and economy of production and maintenance, as well as improved performance characteristics.

  • Anmerkung : Wie man es auf dem Bild ganz oben sehen kann, gab es 1955/1956 zuerst den allerersten Ampex Video-Recorder mit dem waagrecht eingebauten Laufwerk, direkt von den Ampex Audio-Bandmaschinen übernommen. Danach kam der "upright" recorder und dann später die dritte Variante, der Recorder mit dem schräg eingebauten laufwerk. Das hatte sich von der Bedienung her am sinnvollsten erwiesen, weshalb auch alle Nachbauten von RCA und der deutschen Fernseh GmbH gleich auf dieses schräge Laufwerk gesetzt hatten.

Serving the station with space limitations.

The compact, new VR-1002 upright recorder incorporates its components into 11 1/2 square feet of floor space. Two-cabinet construction allows complete flexibility in placement of electronic racks. New Colortec* (an optional direct color system) becomes an integral part of the monochrome system when installed without need for an additional cabinet. An easily detached shelf provides work area for splicing tape and stacking tape reels. A design-coordinated monitor bridge, available as optional equipment, can be placed on top of the upright model for additional conservation of limited space.

Serving the modest-budget station.

Television broadcast stations not faced with major production requirements will find the simplified design and operation of the new VR-1002 Videotape Television Recorder provide a marked saving without sacrificing Ampex's traditional high quality performance. In addition to the reduced price of the VR-1002 - the advanced version of previous upright television tape recorders - its fewer number of tubes, fewer transistors, and simplified circuits minimize time required for set-up. It also reduces routine operational checking, adjustment and maintenance time to provide lowest possible operating cost-per-hour.

Serving as a companion to the VR-1000C.

The VR-1002, an ideal first recorder, is a practical, compatible companion to any Ampex VTR, where there is a need for two recorders. Performance characteristics are identical to the deluxe console VR-1000C. The VR-1002 and a second Ampex VTR permit mixing live, film, slides or network with tape and re-recording on the second unit - or making tape duplicates for syndication. A second recorder also increases operational flexibility by allowing simultaneous recording and "on-the-air" playback, and when running tapes "back-to-back" reduces possibility of errors and resulting "make-goods."

Serving the mobile needs of a Videotape Cruiser.

Why the VR-1002 is the logical choice for mobile operation:

weight of the transport cabinet (800 lbs.) and the electronics cabinet (650 lbs.) totals approximately 200 lbs. less than the deluxe console ... overall height of cabinets is 5'5", excluding monitor ... all cabinets accessible from front or back ... shake-resistant design ... all major tubes and essential components are clamped.

For the station wishing to utilize their VTR for production in the field as well as for in-studio use, quick connect and disconnect arrangements, 20-inch width, and reduced weight makes the VR-1002 the ideal choice.
