Brand: Ampex

The Ampex AG-445B is a professional-grade videotape recorder (VTR) that was introduced in the late 1960s. It used the Ampex quadruplex (4:2:2) color broadcast recording format, which utilizes four tape heads to record and playback video and audio signals onto a single wide tape. The AG-445B was widely used in television studios and broadcasters, as well as in motion picture and video production facilities, to record and play back programming, commercials, and other content. Its high-quality image and sound reproduction made it a popular choice among media professionals. The AG-445B was also used in the late 1970s and early 1980s to create some of the first consumer-grade videocassette recorders (VCRs) and players, such as the Sony Betamax and JVC VHS formats, which were based on the Ampex 4:2:2 technology.
