Reference - Equalization Controls/Options Menu
All onscreen buttons and switches work in Demo mode; however, there is no
communication with connected speakers so parameter changes are not implemented.
• To enable the Control Center Software to display the RMC delay in connected speak-
ers when you "mouse-over" them, click on the Show Speaker Info button.
• The third function in the "Options" area allows you to display delay time in feet,
meters, or milliseconds.
The "Background" and "Listener" sections of the Options menu allow you to change the
appearance of the Room View. Choose from among daylight, dusk, or sunset back-
grounds (or go for stark white if you prefer), and select any of four "listener" heads.
Finally, double-click on the "About This Software" section at the bottom of the Options
menu to view the version number of the software currently installed. This dialog also
provides a hot-link to the JBL Pro website in order to enable you to get technical support
information.
