Audio Video News

Let's face it. Plenty of movie and music fans aren't gearheads. For those who aren't, audio and video equipment is simply a means toward an end. They prefer equipment that literally disappears.

Big speaker boxes are the bane of interior decorators. They've been battling with audiophiles for decades. Home theater, with its reliance on huge powered subwoofers to create realistic bass, has expanded the war.

Not content to rest on their laurels (laurels can be so uncomfortable at times), Atlantic Technology has upgraded their well-regarded System 4200 THX Select home theater speaker system by adding an "e" to the model number. Well, in all honesty, Atlantic Technology has done more than simply reprint brochures with the new nomenclature. (Although it is a great, money-saving idea...) The new improvements include permanently attached finishing panels on the front- and center-channel speakers and a couple of improvements to the system's subwoofer.

Here at Sound & Vision we’ve given quite a bit of coverage to Dolby Atmos so far, and rightly so. Editor Rob Sabin has called it “the most discernible advance in home theater sound since the introduction of lossless digital audio formats on Blu-ray. And it’s one that leaves Dolby Pro Logic IIz and DTS Neo: X (height and width-channel surround formats) in the dust.”

Dolby Atmos, the latest, “object-oriented” surround sound solution magicked up by the San Francisco technologists, has earned enough ink here and elsewhere that many of us are passingly familiar with it already. Briefly, then, object-oriented means that instead of panning discrete effects or overall mixes to left, center, right, or various surround channels, sound designers and producers can now direct sounds through a virtual listening space, letting the computer work out the details. Ultimately, of course, whether at the theater or at home, sounds still emanate from physical loudspeakers driven by physical amplifier channels, so there’s a certain amount of semantics at play here. But Atmos is scalable: A commercial theater can have as many as 64 discrete, individually addressable loudspeakers, including multiple “height” speakers in the ceiling.
