Dolby Surround Encoder

The Dolby SEU4 is for use during soundtrack mixdown to encode discrete four-channel program material (Left, Center, Right, and Surround) for Dolby Surround release. The resulting matrix-encoded two-channel Left total/Right total (Lt/Rt) material can be distributed via any consumer stereo medium, such as two-channel broadcast television (including DTV); VHS videotape; computer and console games; CDs; and two-channel DVDs

The Model SEU4 is not designed for the final mixing of matrix-encoded theatrical film soundtracks. (Dolby Laboratories manufactures dedicated film sound encoders for that purpose.) It can be used however, to preview the effects of the matrix process on discrete four-channel elements (“4-2-4” monitoring) that subsequently will be included in a film soundtrack’s final mix.
