Convergence has come to the automotive market. Clarion Corporation of America announced December 4 that it has developed the the world's first product that integrates car audio, computing functions, navigation, and wireless communications through hands-free voice activation. The Clarion AutoPC is a DIN unit that fits in the dash of an automobile, and is powered by the Microsoft Windows CE operating system.

Among loudspeaker designers, Franco Serblin enjoys an enviable reputation for beautiful creations and meticulous craftsmanship. Until recently, Sonus Faber's resident genius had confined himself to minimonitors with simple crossover networks, such as the Concerto, a Stereophile Class B Recommended Component.

Four years after its first unsuccessful foray into the American consumer marketplace, Sony's MiniDisc appears finally to be winning serious numbers of converts. Several large-scale retailers, including Best Buy, Circuit City, Service Merchandise, and (soon) Sears department stores, have dedicated MiniDisc displays, with home recorders, portable players, and blank discs available individually or as a package deal. The displays were built with Sony's support, according to Mike Viken, senior VP for Sony's personal audio/video marketing division.

It had to happen eventually. Britain's internationally successful loudspeaker manufacturers tend to be highly geared exporters, with overseas markets often accounting for 80-90% of sales. The dramatic downturn in sales across virtually all Asian markets, alongside the collapse of the Russian ruble and an ever-strengthening pound sterling, has been making life very tough indeed.

Is stadium rock passé? The Rolling Stones, the world's greatest practitioners of large-venue concerts, have announced a tour of smaller arenas beginning January 25. The "No Security" tour---in support of the recently released Virgin Records album of the same name---will take the band through 25 North American cities.

It's well known among designers of power amplifiers that the class-A and -A/B amplifiers (referred to as linear amplifiers) used in the majority of car, home, PC, and pro audio systems are notoriously inefficient. They can consume vast amounts of power and yet waste most of it---as much as 80% or more---as heat. They require large power supplies and massive heatsinks, which drive up system weight, size, and cost. On the other hand, class-D amplifiers, using Pulse Width Modulation switching technologies, have good power efficiency but sometimes questionable audio fidelity. (The Spectron designs are possibly the exceptions here.) Class-D amps are used mostly in battery-powered applications in which sound quality might be considered secondary to battery life.

Billy Joel has decided to clean out his warehouse. Next month, the veteran rocker's almost-30-year-old collection of musical instruments, recording equipment, and stage gear will be put up for public auction by Sony Signatures, his merchandising company. A portion of the gross from the "Billy Joel Memorabilia Auction" will be donated to VH1's Save the Music Foundation, according to Dan Cooper, Senior Vice President of Sony Signatures' music division.
