    • AVR-2 (1974) Digital TBC, compact Quad used in studios and remote trucks. Uses 110-volt single-phase AC (other quad models required 220-volt or 3-phase AC service).
    • AVR-3 (1975) Last Ampex Quad, digital TBC. Vacuum capstan. Super high band.
  • VR-2000, VR-1200 and some updated VR-1000, VR-1100E, VR-1195 used modules to correct the playback time base errors of the videotape. The list of modules are:
    • Amtec: Horizontal TBC. All that was needed for B&W playback.
    • Colortec: Color TBC in line after the Amtec for color playback.
    • Velcomp: Color velocity TBC correction for better color playback. Optional on some models.
    • Procamp: Processing amplifier on the final output. New Composite sync insertion, level adjustment.
    • Dropout compensation: Replaced snowy video spots where the FM signal on the tape is missing momentary, caused by a defect in the tape. (optional on some models) Ampex and 3M made different models for the VTR.
    • Editec: (1963) Cue tone editor for frame accurate editing.
      • The components of the VTR were the Servo System, Video Record (Modulator) and Playback De-modulator) and Power Supply.
  • RCA

    • TR-22C (1964) High-band color.
    • TR-2 (1964) Record-only solid state.
    • TR-3 (1964) Playback-only solid state.
    • TR-4 (1964) Both, solid state.
    • TR-5 (1964) Console portable solid state.
    • TR-70 (1966) Solid state, high/low band with dropout compensation.
    • TR-50 (1967) TR-4 high band.
    • TR-60 (1969) High-band & low band color or monochrome. TR-60 is an updated TR-50. RCA's Multi standard machine 405/525/625 lines. The TR-60 & TR-70 were used in the Master Slave Configuration With the TCR-100 Cart Machines timesharing the video processing circuitry of the TR-60 and TR-70 machines when a SPU was not installed with the TCR100.
    • TR-70 High-band & low band color or monochrome. RCA's Multi standard machine
    • TCR-100 (1970) Dual-deck video cartridge machine. SPU-100 was the signal processing unit. had many air-operated mechanisms
    • TR-61 (1972) High-band color, digital servo system, NTSC/PAL switchable, TR-60 is an updated TR-50.

Famous quotes containing the words product and/or models:

    “The UN is not just a product of do-gooders. It is harshly real. The day will come when men will see the UN and what it means clearly. Everything will be all right—you know when? When people, just people, stop thinking of the United Nations as a weird Picasso abstraction, and see it as a drawing they made themselves.”
    —Dag Hammarskjöld (1905–1961)

    “Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
    —Judith Viorst (20th century)
