Kenwood Corporation

Kenwood Corporation 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 Kenwood Corporation rather than just read about it. In short: Kenwood Corporation (株式会社ケンウッド, Kabushiki gaisha Ken'uddo) is a Japanese consumer electronics brand owned by JVCKenwood since 2008. Kenwood is known for manufacturing electronic equipment such as AM/FM stereo receivers, cassette tape decks/recorders, amateur radio (ham radio) equipment, radios, televisions, cellular phones, speakers, and other types of consumer electronics.

Key takeaways

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

Reference excerpt

Kenwood Corporation (株式会社ケンウッド, Kabushiki gaisha Ken'uddo) is a Japanese consumer electronics brand owned by JVCKenwood since 2008. Kenwood is known for manufacturing electronic equipment such as AM/FM stereo receivers, cassette tape decks/recorders, amateur radio (ham radio) equipment, radios, televisions, cellular phones, speakers, and other types of consumer electronics.

History Kenwood was established on 21 December 1946 as the Kasuga Radio Co. Ltd. in Komagane, Nagano Prefecture, Japan. In 1960, the company was renamed Trio Corporation. After that, the company established its first overseas office in 1963, in Los Angeles County, California, United States. During the early 1960s, Trio's products were rebranded and sold by the Lafayette Radio Company, which focused on citizens band (CB) radio. A&A Trading Co. imported Japanese-made electronics for RadioShack. William "Bill" Kasuga, a bilingual Japanese-speaking manager at A&A, partnered with George Aratani and Yoichi Nakase to establish a company as the exclusive importer of Trio products. The name "Kenwood" was invented by Kasuga as a combination of "Ken" (a name common to Japan and North America that was, at the time, considered acceptable to American consumers due to the Kenmore appliance brand) and "Wood" (referring to the material, as well as suggesting a relation to Hollywood, California). Kenwood became more widely recognized than Trio, leading to the company's rebranding. In 1986, Trio acquired Kenwood and subsequently rebranded as the Kenwood Corporation. George Aratani was the first chairman of Kenwood USA Corporation and was later replaced by Kasuga. In October 2008, Kenwood merged with JVC to form a new holding company, JVCKenwood.

Kenwood introduced its Sovereign line of components in 2001. In 2007, it discontinued its line of consumer audio receivers, home theatre systems, and other home electronics.

Products

Speakers Kenwood produces a variety of audio speakers of different grades, ranging from stage sound to high-fidelity.

The company introduced the first car stereo speaker to use a honeycombed linear plane diaphragm.

Amateur radio transceivers

Kenwood has offered lines of HF, VHF/UHF, and portable amateur radio models, including some with built-in digital data modes (Automatic Packet Reporting System, built on AX.25 packet radio) and modems needed to send and receive these protocols.

KA Series hi-fi systems Kenwood launched a series of "Integrated Amplifier" stereo power amplifiers in 1977 and continued their production through the mid-1980s. The design for most of these products featured a true dual-mono path for stereo output (where no electrical components are shared between left- and right-channel amplification). Front plates were typically made in brushed aluminium with aluminium knobs and switches, glass covers, and in some cases analog VU meters. Amplifiers in this series included (in no particular order):

KA-1000 (11/1980) TRIO Supreme 1 KA-2000 KA-2002 (09/1970) KA-2200 (10/1982) KA-3100 KA-6100 (1977) KA-7002 (1971) KA-7100 (10/1976) KA-7300 (10/1975) KA-8100 / KA-8150 (06/1977) KA-8300 (with analog meters vs. 8100) KA-9100 KA-900 (11/1980) KA-907 / KA-9900 (10/1978) KA-9100 / KA-9150 (1977) KA-6100 (09/1978)

NV-Series Compact HiFi Systems The Kenwood NV-301 and NV-701 series were released in 2000.

Communications equipment Kenwood has produced two-way radios for a variety of communications standards, including wireless DECT intercom systems, the radio frequency PMR446 and its digital counterpart DPMR446, DPMR, the Project 25 standards suite, DMR and NXDN. Their communications product range includes hand-portable and mobile terminals (including Intrinsically Safe, ATEX- and IECEx-certified hand-portable radios), repeaters, infrastructure, and application solutions.

Worked examples

Example 1 — a first encounter with Kenwood Corporation

Start with the simplest possible case. Write down what Kenwood Corporation 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 Kenwood Corporation 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 Kenwood Corporation 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 Kenwood Corporation

In research
Kenwood Corporation 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 Kenwood Corporation 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
Kenwood Corporation is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960s initial public offerings, 2011 mergers and acquisitions, Amateur radio companies, so understanding it makes those chapters shorter.
In everyday life
Look for Kenwood Corporation 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.
