New THX Ultra2 Provides Optimum Playback Of All Multichannel Music And Movie Formats

Lucasfilm THX Has Introduced A New Specification, THX Ultra2, For Eight-Channel Playback Of Movie Soundtracks And Music

Establishing a new performance benchmark for home entertainment systems, THX® introduced THX Ultra2.

The THX Ultra2 specification provides uncompromised, eight-channel playback of any multi-channel program, whether movie soundtracks or music, over the widest possible seating area. In addition, all Ultra2 controllers and receivers incorporate video switching, capable of handling all wide bandwidth sources, including HDTV and progressive scan DVD, without degrading the picture. The first THX Ultra2 certified products to be marketed will be two AV receivers from Pioneer Elite -- the VSX-49TX and VSX-47TX, both scheduled for October delivery -- and a home theatre speaker system, pending certification, from Snell Acoustics comprised of the XA1900 LCRs, the AMC900 in-wall dipole surrounds, and a new dual 12-inch powered subwoofer.

"THX Ultra2 is a breakthrough in home entertainment technology -- a single entertainment system that accommodates current and future multichannel formats for both music and movies," said Mark Paddack, Director of Licensing, Lucasfilm THX Consumer Division. "Its advanced technologies deliver the best possible performance while making it easier than ever to extract that performance."

"The new THX Ultra2 specification goes hand-in-hand with Pioneer’s dedication to providing the most accurate multi-channel audio reproduction for both movies and music," said David Bales, Marketing Manager, Pioneer Elite. "Current technology makes it possible to deliver a truly three-dimensional audio experience, but it's more than just adding amplifiers and speakers. It's about making a variety of sources work accurately with a variety of speaker configurations. THX has provided our products with that advantage."

David Smith, President and Chief Engineer of Snell Acoustics, said, "We are pleased to be among the first to offer a product that meets the new THX Ultra2 specification. THX Ultra2 has an emphasis on response smoothness and high output with low distortion, so we felt that our XA1900 LCRs, AMC900 surrounds and new subwoofer would be ideally matched to the specification. Having been the first THX loudspeaker licensee some years ago, it is fitting that we revitalize our THX connection with the new Ultra2 specification."

THX Ultra2 uses seven channels of amplification to play back any multichannel-encoded program through a single, fixed, seven-speaker/one-subwoofer layout. In the new THX Ultra 2 Cinema mode or THX MusicMode, all program material with 5.1 channels or more is auto-detected, and proprietary processing is applied that blends the directional and ambient surround information prior to replay through four surround speakers -- two at the side and two at the back. Ultra2 receivers and controllers also feature switchable Boundary Gain Compensation (BGC) to alleviate "boomy" bass performance that can occur with near-wall listening positions.

THX has drawn on its considerable experience in the design and certification of professional mixing and monitoring facilities to redefine the performance standards needed for the highest quality home speaker systems. The directional characteristics of the new THX Ultra2 LCR and rear surround speakers have been revised to minimize any changes in perceived timbral balance over the widest possible listening area, and Ultra2 subwoofers now have bass extension down to 20 Hz to better reproduce the very low frequency information increasingly found in modern digital multi-channel recordings.
