Cirrus Logic to add Dolby Pro Logic IIx

Cirrus Logic announced that it has incorporated Dolby Laboratories' newest audio algorithm, Dolby Pro Logic IIx, across its multiple family lines of audio DSPs.

Cirrus plans to incorporate the new Dolby standard into the CS49300 and CS49400 DSP chip families in the fourth quarter of 2003.

Already Cirrus is enabling several leading audio manufacturers to take an early leadership position in introducing the new Dolby format into the market, as evidenced by their Dolby Pro Logic IIx demonstrations powered by Cirrus DSP chips at the CEDIA Expo Sept. 3-7 in Indianapolis. Marantz plans to demonstrate the algorithm through its SR7400 receiver, powered by the CS49400, which it plans to ship in November. Harman Kardon said that it also intends to integrate Dolby Pro Logic IIx into selected receivers this fall, and the CS49300 DSP is a key ingredient in Fosgate Audionics’ new FAP T1+ surround processor/preamp, on display in CEDIA Expo booth #1508. The new processor is the first to feature Dolby Pro Logic IIx, an upgrade of Jim Fosgate’s original DPL II technology that now provides a 7.1 solution for high-end enthusiasts who want to enjoy superior multichannel performance from a two-channel source recording.

“Cirrus Logic is proud to reinforce its leadership in audio DSPs by delivering products that support Dolby Pro Logic IIx right now,” said Daryl Sartain, vice president of Digital Audio Marketing, Cirrus Logic. “We’re delighted that leading audio manufacturers such as Fosgate Audionics, Harman Kardon and Marantz have turned to Cirrus to enable their early leadership in showcasing this new Dolby standard.”

Dolby Pro Logic IIx technology delivers a highly immersive and natural 7.1 channel surround-sound listening experience to the home-theatere environment. A product of Dolby’s highly advanced, long-term expertise in surround-sound and matrix-decoding technologies, Dolby Pro Logic IIx provides a complete surround-sound solution designed to maximize the entertainment experience from stereo as well as 5.1 channel encoded sources.
