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.<ref name="history">Kenwood Corporation / Company History</ref>

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.<ref name="news.investors.com">"Entrepreneur Bill Kasuga Courage Helped Him Bring Music To The Public's Ears", by Patrick Seitz, Investor's Business Daily, 21 March 2011 [1] (alternate link: [2])</ref>

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).<ref name="news.investors.com" /> 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.<ref name="history" /><ref>Template:Cite web</ref> In October 2008, Kenwood merged with JVC to form a new holding company, JVCKenwood.

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.
