OPERATION ORBAN MODEL 8685
When a pop-up item, like Menu, is onscreen, E
SCAPE
always returns you
to the underlying screen.
Pressing
E
SCAPE
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.
E
SCAPE
from top-level screens (like the System Setup screen), brings you
back to the Meters screen. (If you are already in the Meters screen,
E
SCAPE
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 towards the front panel displays the pop-up Menu over the
previous screen.
•
Screen Display supplies control setting information and screen help and dis-
plays the gain reduction and level meters (described directly below). In general,
separate meters are shown for the multiband and 2.0 (if active) processing.
The 8685’s screen displays the following information, meters and indica-
tors:
•
Which hardware inputs (1/2, 3/4, 5/6, 7/8, 9/10, and 11/12) have valid AES3id
signals applied to them (indicated by their being displayed in yellow) and
which do not (indicated by their being displayed in red).
•
The current date and time according to the 8685’s internal clock.
•
The active processing Preset.
•
The active Setup.
•
The multiband processor’s active input (main or backup).
If you have programmed silence sense to switch the input of the
surround processing between two inputs automatically, this indi-
cates if the backup input was activated.
•
I

meters show the peak input level applied to the inputs of each of the
8685’s processing channels (up to 7.1) as determined by input routing
switcher settings in

. 0 dB = digital full-scale.
•
AGC meters show the gain reduction of the slow AGC processing that pre-
cedes the multiband compressor (two-band or five-band). Full-scale is 25 dB
gain reduction.
Because the AGC is a two-band unit with Orban’s patented bass coupling
system, the two meters indicate the gain reduction of the AGC Master
and Bass bands.
The AGC gains of the surround processing are always stereo-coupled us-
ing power (r.m.s.) summation. Therefore, only one gain reduction meter
is required for each band. However, the AGC in the 2.0 processing can be
adjusted to be fully stereo-coupled, independent, or anywhere in be-
