Note : To obtain the best performance from the analog to digital conversion process, levels should be set so that the
loudest passages from the source material cause the -18 , -12 and -6 dB ANALOG input LEVEL LEDs on the front
panel to light. Setting the input level too high will cause all four LEDs to light, thus clipping the input signal and causing
distortion.
Analog output levels may vary considerably for different input sources. Program material from a given input source
should not vary as greatly. Therefore the
ANALOG input LEVEL for a given source should not have to be adjusted
very often. If, however, the input
ANALOG LEVEL
LEDs are not lit during the loudest passages from an analog
source, the user should increase the ANALOG input LEVEL for that source in order to ensure a good signal to noise
ratio.
Select the analog input to be adjusted by pressing buttons 1 - 6 once. Adjust the relative input level using the LEVEL
UP / DOWN buttons, then press the SETUP button three times to return to the current INPUT SELECT page.
Jack Names
From the first GLOBAL page, button # 2 accesses a series of sub menus, which allow the user to name all of the
Casablanca II’s input jacks, both audio and video. The
JACK NAMES
sub menu is shown in figure 53.
Figure 53 - Front Panel Display of the SETUP / GLOBAL / JACK NAMES Sub Menu
Pressing button # 1 accesses a sub menu that allows the analog audio input jacks to be named. Button # 2 does the
same for the coaxial digital audio input jacks, whereas buttons # 3 and 4 allow the user to name all non-coaxial digital
audio input jacks. Buttons # 5 and 6 lead to sub menus that allow the naming of the video jacks. The composite, S
and multi format video jacks are internally tied together when it comes to mapping them, and subsequently switching
and naming them. In other words, where
COMPOSITE 1 video jack is mapped, so is the S-VIDEO 1 and Multi Format
1 jack, where COMPOSITE 2 video jack is mapped, so is the S-VIDEO 2 and Multi Format 2 input jack, and so on.
Since the COMPOSITE 1 input jack cannot be mapped differently than the S-VIDEO 1 or Multi Format 1 input jacks,
they also share the same jack name.
Example of editing a jack name:
To edit the name of analog input jack 1, press button # 1 from the menu shown above. This displays the NAME
ANALOG sub menu. Then press button # 1 (first analog input jack name). Press the LEVEL UP / DOWN buttons to
select the desired LCD character and the LEVEL LEFT / RIGHT to change character positions. Once selected, pressing
the DISPLAY button once will clear the current jack name. The character to be edited will blink. The LCD name for all
audio input jacks can be up to 6 characters and the video jack names up to 5. Press the A-D button to edit the OSD
name. OSD will be displayed above the A-D button in the LCD. ALL OSD names can be up to 15 characters and the
current character to be edited will blink.
Remote Power Jacks
The REMOTE POWER jack and three MAIN POWER jacks on the rear panel can be programmed to output 12V, either
straight DC or as a PULSE . This feature is used to automatically turn on other system components such as power
amplifiers, etc, when the Casablanca is taken out of Standby. From the first SETUP / GLOBAL page, press button # 3
to access the REMPWR sub menu shown in figure 54.
