1.2.1 Front-Panel Menu Navigation Buttons
The menu control buttons to the left of the display, shown in Figure 1 ‐ 1 , are used by both
the operator and the service engineer to navigate front ‐ panel screen menus, select various
menu options, and store setup data.
The menu button is used to step through the menu list. Pressing and releasing the button
once changes the display to the next menu item. Pressing and holding the button while
rotating the main fader knob steps the display through all menu items.
The check mark button is used to accept the settings displayed on the front ‐ panel screen
and store it in CP750 memory. Changes to settings occur immediately, but are not
immediately saved.
The button blinks when there are unsaved parameter changes.
1.2.2 Front-Panel Status Display
Day ‐ to ‐ day operation of the CP750 is performed through interaction with the front ‐ panel
status display shown in Figure 1 ‐ 2 .

The top line displays the processing being applied to the audio. The supported processes
are:
• Dolby Pro Logic

Volume Display
The main fader level is displayed as a two ‐ digit number. As with previous generations of
Dolby cinema processors, a fader setting of 7.0 (0 dB) is the nominal correct operating level.
7.0 matches the level used during production of the motion picture.

Meter Display
The circle of lights surrounding the display text serves as channel meters when the CP750
is in use.
