OPERATION ORBAN Model 6200
6200 Front Panel
•
Screen Display labels the four soft keys and provides control setting information.
•
Screen Contrast button adjusts the optimum viewing angle of the screen display.
•
Four Soft Keys provide access to all 6200 functions and controls. The functions of
the soft keys change with each screen, according to the labels at the bottom of each
screen
•
Next and Prev (
←
and
→
) buttons are used to horizontally scroll the screen to ac-
commodate menus that cannot fit in the available space.
These flash when such a menu is in use. Otherwise they are inactive.
•
Control Knob is used to change the setting that is selected by the soft keys.
•
Recall button allows you recall a Factory or User Preset.
•
Modify button allows you to edit a Factory or User Preset. (If you edit a Factory
Preset, you must save it as a new User Preset to retain your edit.)
•
Setup button accesses the technical parameters necessary to match the 6200 to your
transmission system.
•
Escape button provides an escape from current screen and returns user to the next
previous screen. Repeatedly pressing
Escape
will always return you to the Idle
screen.
•
Input meters show the peak input level applied to the 6200’s analog or digital inputs
with reference to 0 = digital full-scale.
•
AGC meter shows the gain reduction of the slow AGC processing that precedes the
multi-band compressor. Full-scale is 25dB gain reduction.
Because the AGC is a two-band unit with Orban’s patented bass coupling
system, this meter actually reads the gain reduction of the AGC Master band.
•
Gate LED indicated gate activity, lighting when the input audio falls below the
threshold set by the gate threshold control (with the Modify screen’s
FULL
CONTROL , GATE THR control). When this happens, the compressor’s recovery time
is drastically slowed to prevent noise rush-up during low-level passages.
•
Gain Reduction meters show the gain reduction in the multi-band compressor. Full-
scale is 25dB gain reduction.
If the Multi-Band structure is operational, all the meters light. If the Two-
Band structure is operational, the two leftmost meters light. If the Protection
Limiter structure is operational, only the leftmost meter lights.
