RCA Dimensia

Dimensia (/dɪˈmɛnsiə/ dih-MEN-see-uh) was RCA's brand name for their high-end models of television systems and their components (tuner, VCR, CD player, etc.)

All Dimensia branded components had this control jack and they all interconnected by using RCA plugs that could piggy-back, resulting in a daisy chain which simplified wiring.

This included several RCA composite video terminals as well as multiple unbalanced and balanced RF antenna/cable inputs.

The components were also connected to the control bus data link via the same piggy-back style RCA connectors.

This variation of the Dimensia featured just the TV monitor mounted in a heavy wood grain veneer with a large input/output panel.

It was not as commercial as the monitor for the full component-based Dimensia system; however, it was still considered high-end and had the control bus.

The second generation console version of the Dimensia had the speakers located on the sides rather than underneath the screen (e.g. Model GPR2750P).

It had both woofers and tweeters in the TV cabinet, whereas almost all standard CRT television sets featured just one (mono) or two (stereo) low fidelity mid-range speaker drivers.

These units were often used in educational facilities or other institutions and had the same chassis as the Colortrak 2000 and Dimensia tabletop model (the primary one).

Retailed at over $5,000 USD upon its release in October 1984,[8] it came with all the matching Dimensia-intelligent components, including the VCR, CED player (canceled just before release, with the Digital Command Center remote's "DISC" button being relabeled "VID2", though some of the manuals for Dimensia components continued to show the original "DISC" button; some CED players released before the Dimensia system hit the market have the special control jack and can be used with the system), amplifier, equalizer, speakers, tuner, cassette recorder, CD player and turntable.

This was the most remarkable system, as all the components were compatible with the TV's computer and almost any operation could be executed with just the push of a button on the Digital Command Center.

[6] These monitors featured BTSC system three-channel audio which had just been adopted by the Federal Communications Commission as the U.S. standard for stereo television transmission in 1984, the same year as the release of Dimensia.

In 1987, RCA released the MSP400 for the second-generation Dimensia audio system, an early Dolby Pro Logic surround sound decoder.
