3.
Assign the JUSTIN 808 to the same signal path as your loop-
through connection. Navigate to
AES Audio Adjustments
/
AES
Airchain
and select either the
Digital HD1
airchain path or the
Analog FM
airchain path.
4.
Tune the JUSTIN 808 to your station. Navigate to
Tuner
and the
default frequency
[
98.10
]
will be bracketed. Push and turn the
jog knob to dial-in your station’s carrier frequency. Signal level
bars on the right side of this screen will indicate incoming sig-
nal quality, and both should be within a bar or two of the top.
The JUSTIN 808 requires a strong incoming signal to do the
best job of correcting timing and level errors. This generally
means an outdoor antenna pointed toward the transmitter site
when the unit is located at the studio. If co-located with the
transmitter, a dangling piece of wire may well suffice.
5.
Set up the time offset and DST. Navigate to
Setup
/
Network
/
Time
/
Time Zone & DST
. Checking the
Auto DST
box will set
Daylight Saving Time for you automatically. Set the
Time Zone
slider to the proper offset as required for your area (e.g.,
UTC
-
8.0
for the US west coast,
UTC
-
5.0
for the east coast).
The correct date and local time will NOT be displayed at the
bottom of the OLED screen at this point. The JUSTIN 808 de-
pends on an Internet time provider for the proper logging and
messaging of alarm events.
6.
Now plug in the network cable and set up the networking pa-
rameters. Navigate to
Setup
/
Network
/
IP Settings
. Set the se-
lection to
DHCP
for automatic IP address assignment by your
router, or to
Static IP
if that’s the mode you elect to use. If you
choose
Static IP
, then you must manually enter values for:
IP:
,
Gateway:
,
Subnet:
and
DNS:
.
VERIFY NETWORK CONNECTION AND OPERATION
Once networking has been set up, go back to
Setup
/
Network
/
Time
/
Time Zone & DST
and verify the correct date and time at
the bottom of the OLED screen.
At this point the JUSTIN 808 should be into its autocorrelation
routine. Soon the front-panel
ALIGNMENT
indicator will stop
its side-to-side ‘searching’ motion.
7.
Navigate to
FM/HD Measurements
/
FM/HD Radio Time
. When the
JUSTIN 808 calculates the timing misalignment, this will be in-
dicated under
Measured Delay
, both in the number of
Samples
and in milliseconds of
Time. Status
will show whether the HD is
leading or lagging the FM.
The
Applied Delay
numbers will slowly increase as the
Measured
Delay
numbers decrease. You may accelerate this process by
navigating to
Setup
/
Instant Jump
and actuating the
Go!
button.
