made into memory automatically, or simply ‘deselect’ the high-
lighted item if it has not been altered.
The BACK
Button
BACK
button
B
will always return you to the previous menu
screen. Push it repeatedly to go back to the Main Menu shown
in the illustration.
If you make a mistake (for example, you might push the knob
slightly off-center, which could also rotate the knob and bring
up the wrong menu), simply push the
BACK
button to return to
the previous menu and try again.
Graphic
Display
OLED graphic display screen
C
presents an abbreviated, intui-
tive setup menu tree in an easy-to-follow format. The display
uses a screen saver, so if the screen goes dim or dark, simply
push the jog-wheel knob or
BACK
button once to bring it back
to life. No selection or change is made with this ‘wake-up call.’
Local Alarms
Front-panel alarm LEDs
D
indicate critical reception errors.
Programming the alarm thresholds and delays is accomplished
through the Web interface as described starting on Page 25.
Level Meters
LED-segment meters
E
are
LEFT
and
RIGHT
channel audio level
indicators with peak response to program dynamics. A floating
peak-hold segment catches the most recent peak level.
The full-scale
0dB
reference corresponds to ±75kHz monaural-
FM modulation or nominal 100% HD Radio modulation. Meter
scaling is linear at 3dB per segment down to
–18dB
, then 6dB
per segment to
–30dB
.
–60dB
at the bottom is essentially the
peak-weighted noise floor for analog FM.
Because these meters are peak- rather than averaging- or VU-
responding, you’ll find that they will typically hover right at the
top of the scale during most music programming, which nowa-
days has very limited dynamic range.
Menu Timeout
and Screensaver
After making and saving a setting, you may press the
BACK
button to return to the Main Menu screen, or simply leave any
current screen showing.
A programmed interval may be set under the Admin / Display
menu to adjust screen brightness and to dim or turn off the
OLED screen when the SOFIA 568 is unattended. This is a rec-
ommended practice that prolongs the life of the display. At
any time, however you can press the jog-wheel knob or
BACK
button to bring-up the OLED screen.
THE FRONT-PANEL MENU TREE
The several levels of front-panel setup and operating menus are
laid out in an intuitive and easy-to-manage fashion. The com-
plete Menu Tree is shown and explained below. Keep in mind
that the front-panel Menu Tree is a much-abbreviated version of
total SOFIA 568 setup and operation navigation.
