OPERATION ORBAN Model 8400
8400 Front Panel
Headphone Jack allows you to monitor the output of the processing through head-
phones. When the HD option is installed, you can choose the output of the FM or HD
processing. Headphone impedance should be 75Ω or higher.
The headphone jack is connected to chassis ground, not circuit ground. There-
fore, the headphones will not work if the 8400
GROUND switch is in the Lift
position and there is no other connection between the 8400’s circuit and chas-
sis grounds.
Headphone Level Control (the blue control knob to the right of the jack) adjusts head-
phone volume.
The red Enter button allows you to choose pop-up menu items, icons and buttons. If you
are in the Preset screen, it allows you to put a Factory or User Preset on-air once you
have selected it.
If you edit a Factory Preset, you must save it as a new User Preset to retain
your edit.
The green joystick, labeled Locate, is a pointing device that allows you to navigate to
settings and controls on each screen. If multiple screens are available, pressing and hold-
ing the knob left or right moves you to the previous and next function screens.
The yellow Escape button allows you to navigate quickly to underlying screens, higher-
level screens or the Meters screen, or displays the pop-up menu.
When a pop-up item, like Menu, is onscreen, Escape always returns you to
the underlying screen.
Pressing
Escape from a secondary screen page, like System Setup:
Place/Date/Time 1 takes you back to the top level; in this case, the System
Setup screen.
Escape from top-level screens (like the System Setup screen), brings you
back to the Meters screen. If you are already in the Meters screen, Escape
displays the pop-up Menu.
The Control Knob is the large blue knob on the front panel. Turning the knob scrolls
through displayed lists (like the Preset screen list) or changes a setting that is highlighted
onscreen (e.g., the setting last selected by the Locate joystick). Pushing the knob in, to-
wards the front panel, displays the pop-up Menu over the previous screen.
Screen Display supplies control setting information and screen help, and displays the
gain reduction and level meters (described directly below).
The 8400’s color LCD displays the following meters and indicators:
In meters show the peak input level applied to the 8400’s analog or digital inputs with
reference to 0 dB = digital full-scale. If the meter reads at the top of the scale and the ana-
log input is active, this indicates clipping in the A/D converter.
