XL-100
The XL-100 was a line of solid-state television sets introduced by RCA in 1971. The "XL" stands for extended life chassis while the 100 refers to RCA's emphasis of 100% solid-state chassis. Initially the top-of-the-line RCA color televisions, they would become lower-end as the Colortrak and Dimensia series were introduced (in the mid-1970s and early 1980s, respectively) The original models replaced the RCA "Vista" and "New Vista" color television series. The XL 100 name was discontinued in the late 1990s. Expansion of RCA model lines based on the XL-100 chassis During later model years, the XL-100 line became the middle and then lower-priced color televisions in the RCA lineup. RCA introduced the "Colortrak" in 1976 and toward the end of analog television, the "Dimensia" lines in the mid 1980s. In later years, all three TV lines used the same RCA CTC-xxx (CTC is RCA's acronym for Color TV Chassis) chassis and the main differences were in cabinet design and electronic features. ...

RCA XL-100 20110627
RCA Corporation was a major American electronics company, which was founded in 1919 as the Radio Corporation of America. It was initially a patent trust owned by General Electric (GE), Westinghouse, AT&T Corporation and United Fruit Company. In 1932, RCA became an independent company after the partners were required to divest their ownership as part of the settlement of a government antitrust suit. An innovative and progressive company, RCA was the dominant electronics and communications firm in the United States for over five decades. In the early 1920s, RCA was at the forefront of the mushrooming radio industry as a major manufacturer of radio receivers, and the exclusive manufacturer of the first superheterodyne sets. The company also created the first nationwide American radio network, the National Broadcasting Company (NBC). RCA was also a pioneer in the introduction and development of television, both black and white and especially color television. Throughout most of t ...

Colortrak
Colortrak was a trademark used on several RCA color televisions beginning in the 1970s and lasting into the 1990s. After RCA was acquired by General Electric in 1986, GE began marketing sets identical to those from RCA. GE sold both RCA and GE consumer electronics lines to Thomson SA in 1988. RCA televisions with the Colortrak branding were mid-range models; positioned above the low-end XL-100 series but below the high-end Dimensia and Colortrak 2000 series. RCA discontinued the Colortrak name in the late 1990s, with newer models badged as the Entertainment Series. Design quirks During the early 1980s, RCA responded to increased demand for component televisions with monitor capabilities by adding composite video, composite and S-video inputs to the Colortrak lineup. These inputs allowed owners to easily connect a stereo audio/video source, like a VCR, Video Cassette Recorder, LaserDisc, LaserDisc player, or with use of an RCA SelectaVision, SelectaVision CED videodisc player to th ...

Solid-state Electronics
Solid-state electronics are semiconductor electronics: electronic equipment that use semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay, in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD), a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk. History The term ''solid-state'' became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of elect ...

Dimensia
''Dimensia'' ( ) was RCA's brand name for their high-end models of television systems and their components (tuner (radio), tuner, VCR, CD player, etc.) produced from 1984 to 1989, with variations continuing into the early 1990s, superseded by the ProScan model line. After RCA was acquired by General Electric in 1986, GE sold the RCA consumer electronics line to Thomson SA which continued the Dimensia line. They are significant for their wide array of advanced features and for being the first television receiver systems to feature a built in computer, somewhat of an early incarnation of a smart TV, but without internet access (see Technological convergence). In 1985, RCA released the Digital Command Component System, a fully integrated audio system that permitted the full functionality of Dimensia audio components without a Dimensia monitor. The name "Dimensia" actually dates back to the early 1970s when RCA used the term for an enhanced spatial stereo effect which they called "Dim ...

Dipole
In physics, a dipole () is an electromagnetic phenomenon which occurs in two ways: * An electric dipole moment, electric dipole deals with the separation of the positive and negative electric charges found in any electromagnetic system. A simple example of this system is a pair of charges of equal magnitude but opposite sign separated by some typically small distance. (A permanent electric dipole is called an electret.) * A magnetic dipole is the closed circulation of an electric current system. A simple example is a single loop of wire with constant current through it. A bar magnet is an example of a magnet with a permanent magnetic dipole moment. Dipoles, whether electric or magnetic, can be characterized by their dipole moment, a vector quantity. For the simple electric dipole, the electric dipole moment points from the negative charge towards the positive charge, and has a magnitude equal to the strength of each charge times the separation between the charges.

Coaxial
In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis. The two-dimensional analog is ''concentric''. Common examples: A coaxial cable has a wire conductor in the centre (D), a circumferential outer conductor (B), and an insulating medium called the dielectric (C) separating these two conductors. The outer conductor is usually sheathed in a protective PVC outer jacket (A). All these have a common axis. The dimension and material of the conductors and insulation determine the cable's characteristic impedance and attenuation at various frequencies. Coaxial rotors are a three-dimensional planar structure: a pair of helicopter rotors (wings) mounted one above the other on concentric shafts, with the same axis of rotation (but turning in opposite directions). In loudspeaker design, coaxial speakers are a loudspeaker system in which the individual drivers are mounted close to one another on the same axis, and thus radiate sound along t ...

Digital Data
Digital data, in information theory and information systems, is information represented as a string of Discrete mathematics, discrete symbols, each of which can take on one of only a finite number of values from some alphabet (formal languages), alphabet, such as letters or digits. An example is a text document, which consists of a string of alphanumeric characters. The most common form of digital data in modern information systems is ''binary data'', which is represented by a string of binary digits (bits) each of which can have one of two values, either 0 or 1. Digital data can be contrasted with ''analog data'', which is represented by a value from a continuous variable, continuous range of real numbers. Analog data is transmitted by an analog signal, which not only takes on continuous values but can vary continuously with time, a continuous real-valued function of time. An example is the air pressure variation in a sound wave. The word ''digital'' comes from the same sour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RCA Jack
The RCA connector is a type of electrical connector commonly used to carry analog audio and video signals. The name refers to the popular name of Radio Corporation of America, which introduced the design in the 1930s. Typically, the output is a plug type connector and the input a jack type connector. These are referred to as RCA plug and RCA jack respectively. It is also called a phono connector, referring to its early use to connect a phonograph turntable to a radio receiver. As home audio systems became more complex, RCA cables became a standard way to connect components such as radio receivers, amplifiers, turntables, tape decks, and CD players. Their ubiquity led to them also being used for video: connecting analog televisions, videocassette recorders, DVD players, and game consoles. They remain in use as a simple, widely supported means of connection. In some European countries such as France and Germany, the name ''cinch'' is still used as an antonomasia of ...
