[. . . ] THETA DIGITAL C O R P O R A T I O N Casablanca III Owner's Manual V 3. 00 Rev B3 Digital Done Right TM PREFACE CONGRATULATIONS You have just acquired the most advanced component for the control and processing of audio and video ever to have been developed. IMPORTANT Save all packaging in a dry place away from fire hazards. Your Casablanca III is a precision electronic instrument and should be properly packaged any time shipment is made. In the unlikely event that you have to return your Casablanca III to the factory for service, or if you send it to us for updating, the original packaging will best protect the unit from shipping damage. In order to achieve the fullest flexibility and enjoyment from your Casablanca III, we at Theta recommend that you read this manual in full before connecting the unit to your audio/video system. WARNING United Stated law prohibits disposition of these commodities to Libya, Laos, North Korea, Cambodia or Cuba unless otherwise authorized by the United States. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. [. . . ] 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. Casablanca III contains three parameters to control Dolby Digital compression. Button # 3 (CMP) turns the compression ON or OFF. Button # 4 (HCMP, or High Compression) controls the degree to which loud passages will be reduced. Button # 5 (LCMP, or Low Compression) controls the degree to which quiet passages will be increased. Note: Some Dolby Digital sources do not allow for compression, in which case altering these settings will have no effect. Dialog Normalization Press button # 6 to set the dialog normalization value. Dolby Digital contains the useful provision for making all Dolby Digital sources play back at the same average volume level, even though they have been recorded or mixed at very different levels. This is done by embedding in the data stream a value that the program material will need to be adjusted by to conform to an average dialog level established by Dolby Laboratories. It should be noted that the relative levels of all channels are adjusted, not just the center channel. Casablanca III contains two options for this setting: ANLG (analog) or DIGI (digital). ANLG: Dialog normalization will be applied in the analog domain. This is the best-sounding and preferred 66 setting. DIGI: Dialog normalization will be performed in the digital domain. Digital reduction of volume results in a significant loss of resolution. *** Press the A-D button to access Page 2 of the Dolby Digital set up submenu, which is shown in figure 48. Figure 48 - Front Panel Display of the SETUP/INP Page 2/DOLBY DIGITAL Page 2 Submenu This submenu allows the user to adjust the center, side and surround speaker delays and levels, LFE level and processing for additional speakers when the MODE is Dolby Digital. It is important to note that the level and delay settings in this submenu are added to or subtracted from those in the main SETUP/INP/LEVELS and SETUP/INP/DELAYS submenus. For example: if the center level (CLVL) in this submenu is set to ­2 and the center level in the SETUP/INP/LEVELS submenu were set to +3, the overall center level, when the MODE for the currently selected input is Dolby Digital, would be +1. This same process applies to the delays. It is important to note that the Casablanca III does not support negative delays based on the theory that even we at Theta cannot make time go backwards. Therefore the sum of the delays cannot be less than 0. As an example, if the center delay in the SETUP/INP/DELAYS submenu were set at 0 and in the Dolby Digital setup submenu set at ­1, the overall center delay would be 0.
