Colortrak 2000 was a brand name used for RCA's high-end television models produced from the early-1980s to the early 1990s. Colortrak 2000 was situated above the less expensive Colortrak line, but below the more expensive Dimensia line. As opposed to ColorTrak, ColorTrak 2000 models incorporated a comb filter, which provided a sharper picture. The Colortrak 2000 chassis was identical to the Dimensia tabletop model. Colortrak 2000s with BNC connectors were given the designation of Lyceum TVs. This TV set was also used with RCA's Digital Command Component System released in 1985.[1]
