  • 1. 27.03.2013 ORBAN INTRODUCES UPMIXER IN OPTIMOD-TV 8685 AND 6585March 26, 2013 Scottsdale, Arizona - Orban, a worldwide leader in audio processing for AM, FM, TVand Internet broadcasting, announces that the Orban Optimod-TV 8685 and 6585 automatic loudnesscontrollers for surround and stereo channels in digital television will provide an internal, Orban-designed stereo-to-surround upmixer at no additional charge. The upmixer automatically detectswhether programming is in stereo or surround and upmixes or bypasses as appropriate. The upmix isdirectionally stable with a solid center channel, and avoids the “image steering pumping” introducedby consumer upmixers that have been repurposed for transmission. A new, highly robust algorithmeliminates the effects of phase and azimuth skew in the derived center channel, ensuring crisp, highlyintelligible dialog even from older material that has been stored on analog tape. All existing 8685 and6585 users can upgrade to the new upmixer via a free software download, expected to be available inApril 2013.The Optimod-TV 8685 is Orbans second-generation surround/2.0 processor, offering 3G HD-SDI I/O,CBS Loudness Controllers and meters, a BS.1770 safety limiter, and BS.1770-3 loudness meters. Anincluded application allows the BS.1770 loudness to be logged to a PC, creating proof of complianceof the CALM Act. The 8685 can process one surround and four stereo programs simultaneously.Orbans value-priced Optimod-TV 6585 surround/stereo television loudness controller builds onOrbans 30+ year experience in television audio processing to provide audibly transparent automaticloudness control and dialog intelligibility control for one surround program (up to 7.1) or four stereo(stereo) programs. The stereo processing can operate in dual-mono mode, so it can process foursubchannels in stereo or eight subchannels in mono. Put in-line and operated correctly, the 6585, likethe 8685, will ensure and document that loudness meets the requirements of the CALM Act and EBUR-128. [--end--]
