Setup Dolby Digital Button # 4 provides a two-page sub menu, which allows the user to set up preferences pertaining to Dolby Digital (AC-3), by INPUT SELECT button. The first page of this sub menu is shown in figure 36. Figure 36 - Front Panel Display of the SETUP/INP Page 2/DOLBY DIGITAL Page 1 Sub Menu 2 Channel Mode Some Dolby Digital sources contain only two of the possible five main channels. This is usually noted on the material's cover, in the form of "2. 0" as opposed to "5. 1". In the event that the Dolby Digital source is two channel ("2. 0" or "2. 1"), Casa Nova provides the user with the ability to apply a surround sound process. There are three options for this setting: "Pro Logic" (PRO), "none" (STER) or "auto" (AUTO). Press button # 1 (2CHMDE, or two channel mode). Pro Logic (PRO): Any two-channel Dolby Digital source will automatically have Dolby Pro Logic surround mode applied to it, thus producing a Dolby Surround output. None (STER): Any two-channel Dolby Digital source will have no additional surround processing applied to it, thus producing a two-channel (stereo) output. AUTO: Embedded in every two-channel Dolby Digital datastream is an indication of whether or not the material is Dolby Surround encoded. There are three possibilities for this indication: Dolby Surround encoded; Not Dolby Surround Encoded; No Indication. If the indication is that the material is Dolby Surround Encoded, Dolby Pro Logic processing will be performed thus producing a Dolby Surround output. If the indication is that the material is not Dolby Surround encoded, or there is no indication, no additional surround processing will occur thus producing a two-channel (stereo) output. 31 Compression Dolby Digital contains provisions for reducing the dynamic range of a Dolby Digital source. This means reducing the loudness of the loud passages and increasing the loudness of the quiet passages. Possible reasons for reducing the dynamic range of a source include late night listening wherein loud moments may disturb others, and making tapes for automotive / portable use wherein quiet passages may not be heard. Casa Nova contains three parameters to control Dolby Digital compression. Button # 2 (COMP) simply turns the compression ON or OFF. Button # 3 (HCMP, or High Compression) controls the amount that loud passages will be reduced. Button # 4 (LCMP, or Low Compression) controls the amount that quiet passages will be increased. A larger number indicates a greater amount of increase or decrease.
