Realistic (brand)

Realistic (brand) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Realistic (brand) rather than just read about it. In short: Realistic was a private label consumer electronics brand produced by RadioShack. Initially only a home audio equipment brand, its product line expanded to include CB radios, walkie-talkies, and video camcorders by the 1980s.

Key takeaways

  • Realistic (brand) belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Realistic (brand) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Realistic (brand) from memory before moving on to harder problems.

Reference excerpt

Realistic was a private label consumer electronics brand produced by RadioShack. Initially only a home audio equipment brand, its product line expanded to include CB radios, walkie-talkies, and video camcorders by the 1980s. The brand was discontinued in 1994, but revived for a short time in 2016 for use on Bluetooth devices sold by the chain.

History The brand began in 1954 after Radio Shack management were approached by stereo newcomer Harman Kardon, who offered to help create a line of private label audio equipment for the company. The original brand name, Realist, was pitched by the manufacturer and approved by Radio Shack. The first Realist-branded products - an FM receiver, an AM receiver, and a matching 10-watt amplifier with a built-in preamp - were introduced later that year. These would be the only Realist-branded products, as the brand’s name was challenged by the David White Company, manufacturer of the Stereo Realist camera in 1955. The change to Realistic that year was reportedly made just in time before Radio Shack’s 1956 catalogs were to be printed. The company's most notable products under the Realistic brand included the extensive line of TRC series Citizens Band radio transceivers, which dominated the CB Radio market during the 1970s, and included the Navaho series of CB base station units. A 1977 motion picture entitled Handle with Care was sponsored at the time by Tandy Corporation, in part to showcase the line. Also notable were their 8-track tape recorders under the TR- model line and their compact cassette decks under the SCT- model line. They are also the company responsible for the Realistic Mach speaker line. A very wide range of products was marketed under the Realistic brand. These included record players, stereo receivers, cassette decks, ham radios, musical synthesizers and a few quadraphonic receivers and shortwave radios.

Optimus In 1993, Tandy Corporation sold off the bulk of its manufacturing facilities in a bid to not only cut costs but offer more brand-name electronics in lieu of their own. The Realistic name carried on into 1994 as the rest of the Tandy-produced stock was slowly being sold off. In that year, all outsourced audio equipment formerly bearing the Realistic name would carry the Radio Shack name, and the video equipment was renamed to Optimus, another private label audio equipment brand sold by the company since 1967. In May 1999 it was announced that the Optimus brand would be retired, after RadioShack entered an agreement with RCA to market their products.

Realistic enjoyed a short-lived return to RadioShack's stores in 2016, with a line of wireless Bluetooth speakers and wireless noise-canceling Bluetooth headphones.

Quatravox Quatravox was the name of Realistic's synthesized four-channel output version of quadraphonic sound, which used Hafler circuitry to reproduce ambient sounds recorded by the microphones 180° out-of-phase with the intended recording (sounds recorded from opposite the microphone from the performers, i.e., studio echo, audience noise, etc.) and play them back through the rear loudspeakers out-of-phase with the main loudspeakers. The effect is a greater degree of separation than stereo sound, as the listener is able to hear echoes, applause, and other ambient sounds from behind (as opposed to in-front and thus out-of-phase with the main speakers and inaudible), even with stereo recordings. However, this degree of separation is not as great or as flexible as that of truly discrete quadraphonic sound.

Models The Realistic DX-60 is a multiband radio. The radio receives 3 MHz to 27 MHz AM shortwave in three bands, 26.965 MHz through 27.405 MHz HF CB in one band, 540 kHz to 1620 kHz standard AM broadcast in one band, and 87 MHz to 108 MHz monaural standard broadcast FM. The DX-60 existed in two versions, model 12-764 and a nearly identical but production-cost-reduced 12-764A. The Realistic Patrolman SW-60 and the Realistic CB-60 are similar in overall appearance but cover different sets of bands. The Realistic DX-150 and DX-160 series of Shortwave (LW/MW/SW) radios were affordable communications receivers, aimed largely at beginners, that also received SSB and CW via a BFO. Probably thousands of SWL's, MW DX'ers, and future hams got their start listening to the SW broadcast and SW ham bands with these radios.

Worked examples

Example 1 — a first encounter with Realistic (brand)

Start with the simplest possible case. Write down what Realistic (brand) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Realistic (brand) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Realistic (brand) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Realistic (brand)

In research
Realistic (brand) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Realistic (brand) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Realistic (brand) is common in secondary-school and first-year university syllabi. It links to neighbouring topics American companies established in 1954, Audio equipment manufacturers of the United States, Defunct brands, so understanding it makes those chapters shorter.
In everyday life
Look for Realistic (brand) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
