Harman Kardon AVR30 Owners Manual - Page 16

Using the Digital Signal Processor (DSP) Purpose of the Digital Signal Processor The AVR30 incorporates a sophisticated Digital Signal Processor which allows the user to expand and shape the soundfield from audio and video sources. The unit has 7 modes, two Dolby Pro Logic modes and five Digital Signal Processor modes. This unit simulates different size performance venues such as a small night club or a small movie theater or even a large stadium with a clarity and realism unheard in other processors. Description of Dolby Pro Logic Surround The Dolby Pro Logic in this system is similar to professional Dolby Stereo decoders used in movie theaters. The Dolby Pro Logic Surround system employs four-channels: the left and right main channels, the center channel (to characterize dialogue), and the rear surroundsound channels (to characterize sound effects, background and other ambient information). Dolby Surround is encoded on the sound track of commercially available video cassettes and video discs as well.
