  • Page 50: Setup Function

    SETUP Function This function provides access to a series of submenus that will allow the configuration of the entire system. In this section, each feature of the SETUP menu is discussed in detail along with a diagram of each VFD display. Note: A complete step-by-step speaker configuration setup guide is located on page 24.

  • Page 51: Setup Input (Settings Specific To Each Of The 12 Input Select Buttons)

    Figure 23 - Menu Map of SETUP/INP Page 1/CONFIG The configuration submenus (CONFIG) allow the user to configure the Casablanca IV to reflect the audio system configuration or the listener’s preference for the available speakers and their respective frequency responses.
  • Page 52 Figure 25 - Front Panel Display of the Subs Configuration Submenu Unlike most configuration submenus in the Casablanca IV, this one is not dynamic. In other words, if there are 1-5 DAC channels installed that are configured as subwoofers, this submenu will show, and allow configuration editing for all 5, except for the #SUBS parameter.
  • Page 53 If the #SUBS 4, they will be assigned to Front L/R and Rear L/R. Each sub will get ¼ of the LFE. Additionally, the low pass signal from any front speakers that are crossed over will be routed to the front subs (SUB 1 and SUB 2) and the low pass signal from any surround speakers that are crossed over will be routed to the surround subs (SUB 3 and SUB 4).
  • Page 54 Crossovers The Casablanca IV contains Linkwitz-Riley crossover filters. Combined with knowledge of the actual in-room frequency response of each speaker in the system as measured by Theta Digital’s Dirac Live® 96 kHz module, the end results can offer state-of-the-art performance..

This submenu is shown in figure 32. Figure 32 - Menu Map of SETUP/INP Page 1/CONFIG/SURR This submenu of settings for the back surround speakers is virtually the same as the one for the center speaker.
  • Page 58 Like the speaker configuration menus, the level submenu(s) will reflect the DAC channels that are installed in the Casablanca IV. If there are 6 DAC channels installed, the names of these channels will be displayed on one page of the levels submenu. If more than 6 DAC channels are installed, a menu will appear asking the user which set of speakers are to have their levels adjusted: 1-6 or 7-12, as shown in figure 34.
  • Page 59 Internal Noise Generator To aid in establishing a desired system speaker level balance, the Casablanca IV provides the user with the option of routing the currently selected audio signal or an internally generated noise signal to a selected speaker. This function is accessed via the A-D button in the SETUP/INP/LVLS submenu(s). Press buttons 1-6 to select a speaker.
  • Page 60 If more than six DAC channels are installed in the Casablanca IV, there will be a right arrow above the A-D button. Press this button, and the second Delay page will be presented as shown in figure 38.
