user’s Casablanca II if the same DAC channels are not installed and configured.
Figure 34 - Front Panel Display of the SETUP / INP / LVLS 7-12 Sub Menu
In these submenus, press button(s) 1 - 6 to select a speaker to edit. Use the LEVEL UP / DOWN buttons to adjust each
speaker’s output level. If there is a level control on the sub itself, adjust that first and then fine tune with the
Casablanca II.
Internal Noise Generator
To aid in establishing a desired system speaker level balance, the Casablanca II provides the user with the option of
either routing the currently selected audio signal to the outputs, or routing an internally generated noise signal to either
the currently selected speaker or to all speakers simultaneously.
This function is accessed via the A-D button in the SETUP / INP / LVLS sub menu(s). Press buttons 1 - 6 to select a
speaker. Pressing the A-D button repeatedly toggles through these sources. Table 5 shows the 3 possible routings.
When the A-D button is pressed, the source name or noise type will appear in the LCD below the sub menu title.
Table 5 - Source to Output Routing for Speaker Level Configuration.
When use of the noise generator is complete, press
A-D to once again re-route the SOURCE to the outputs.
Note : It is recommended that levels be set relative to the front Left and Right speakers. The first step would be to
adjust the front Left and Right level value(s) to zero dB, then with the noise generator set to output to the left front
speaker, adjust the master volume. Then adjust all other individual speaker levels. The remaining speakers can be
adjusted accordingly by pressing buttons
2-6 one at a time, then pressing LEVEL UP or LEVEL DOWN to increase or
decrease each speaker’s relative level using an SPL meter, until the desired system balance is established. Please
refer to the detailed
Step-by-Step Setup Guide on page 15.
Speaker Delays
Like the Levels sub menu(s), the Delays submenu(s) are interactive. Depending on what DAC channels are installed in
the Casablanca II determines what speaker channels are shown in the Delays sub menu, and whether or not there are
one or two Delays sub menus. Unlike the Levels sub menus, if there are two Delays sub menus, navigating between
them is accomplished via the
A-D button.
The Delays sub menu allows the user to set a time delay for each speaker to reflect the audio system configuration,
room characteristics, or the listener’s preference. Another way to look at it is that the sound from all speakers should
reach the listening position at the same time and this sub menu provides a means for achieving just that. The
allowable range for the front left/right, center and sub speaker(s) is
0 to 10 milliseconds (mS) and 15 to 31 mS for the
side and surround speakers. Since discrete sources are often recorded with surround delays, it is recommended that
the surround delay setting for 5.1 sources be 15 mS less than non 5.1 sources.
