History

edit

The company was established in 1946 as the Kasuga Radio Co. Ltd. in Komagane City, Nagano Prefecture, Japan. In 1960, the company was renamed to Trio Corporation. In 1963, the first overseas office was founded in Los Angeles County, California, USA.[2]

In the early 1960s, Trio's products were rebranded by the Lafayette Radio Company, with a focus on citizens' band radio.

A&A Trading Co. imported Japanese-made electronics for RadioShack. William "Bill" Kasuga, a bilingual Japanese-speaking manager from A&A, partnered with George Aratani and Yoichi Nakase to establish a company as the exclusive importer of Trio products.[3]

The name Kenwood was invented by Kasuga as a combination of "Ken" (a name common to Japan and North America that was considered acceptable to American consumers due to Kenmore appliances), and "Wood" (referring to the durable substance, as well as suggesting a relation to Hollywood, California).[3] The brand recognition of Kenwood eventually surpassed that of Trio. In 1986, Trio bought Kenwood and renamed itself Kenwood. George Aratani was the first chairman of Kenwood USA Corporation, and was later succeeded by Kasuga.[2] In October 2008, Kenwood merged with JVC to form a new holding company, JVCKenwood.

Front plates were typically made in brushed aluminum with aluminum knobs and switches, glass covers, and in some cases analog VU meters.

Amplifiers in this series included (in no particular order):[4]

edit

These were a series of mini hi-fi systems launched in 2000, featuring a new design aesthetic.

NV-301/701

The NV-301 and NV-701 both shared a three-layered half-mirrored design. The NV-301 was the basic model with two speakers and a line input (marked for MiniDisc and DVD players) while the NV-701 was a 5.1 Dolby surround sound model with A/V inputs. Both featured a three-disc carousel, cassette player with Dolby B noise reduction, natural display, intelligent features and the ability to save up to 40 radio stations, utilising microcomputers to reduce the size of the unit.
