iMix Decoder 257

The iMix Surround Audio Decoder 257 uses a patented DSX Surround algorithm for upmixing stereo audio to 5.1 and 7.1 surround for gaming, film, live sports and television productions. By combining several technologies including frequency- and time-domain energy distribution and the latest psychoacoustic models, the DSX Surround algorithm provides artifact-free, stable surround stems with complete downmix compatibility.

The DSX 257 Surround algorithm processes true stereo signals (LR) giving a pleasing surround sound image and well-centered dialog. Completely compatible with matrix-encoded stereo signals (LtRt) including Dolby® ProLogic®, Dolby® ProLogic II®, and SRS Circle Surround, the DSX 257 Surround algorithm upmixes matrixed LtRt content to a coherent, spatially accurate 5.1 surround sound mix. Previously downmixed DSX Surround and DTS Neural Surround™ (LtRt) content is completely restored to the original discrete 5.1 stems using Orban’s iMix Surround 257.

The Orban iMix 257 can be used as a stand-alone unit to decode stereo LtRt in production environments, upmix stereo content for TV commercials and film trailers or in tandem with Orban’s new iMix 5.1 Monitor-DownMix as a complete 5.1 transport solution.
