Meridian Audio has just announced the availability of Dolby Laboratories’ latest surround technology, Pro Logic IIx, in its new G68 and flagship 861 surround processors, making Meridian the first company in the world to offer this technology in their products.

The G68 is part of the new G Series range of players, processors, amps and controllers recently announced by Meridian. G Series products will be shipping by October, 2003. The 861 and the 568.2 processors can be upgraded to include Dolby Pro Logic IIx by means of a firmware upgrade, available for download free of charge and installed via the product’s serial port.

Dolby’s new Pro Logic IIx takes advantage of multiple amplifiers and loudspeakers in a 6.1 or 7.1 system, decoding and expanding stereo and 5.1 content for replay via systems with side and rear speakers in addition to the usual front three and pair of surrounds. The result is a seamless, wraparound soundfield over a wide listening area, maintaining the sonic integrity and purity of sound for which Dolby Pro Logic II technology is well known, without requiring specially encoded content.

Meridian’s implementation of Pro Logic IIx has been carried out with full 48-bit precision, offering the surround clarity and detail. Meridian’s Dolby Pro Logic IIx Music, Movie, and THX modes replace existing implementations of their Pro Logic II equivalents. Listeners with four surrounds will benefit most from the new features.

Pro Logic IIx also offers new capabilities for multichannel input from PCM, DTS, AC-3 or MPEG sources. Meridian will offer 5.1 upscaled to 7.1 where all four surround signals are different. In the case of movies, EX is renamed Pro Logic IIx EX, with a menu to choose between Surround EX and Pro Logic IIx (7.1). Meridian systems fully support 0, 2 or 4 surround speakers at present.
