your station.
After this step, you can always select a different processing preset, pro-
gram the 8300 to automatically change presets on a time / date schedule,
use a GPI input to trigger preset changes, modify presets to customize
your sound, and store these presets as User Presets.
Preset names are just suggestions. Feel free to audition different presets
and to choose the one whose sound you prefer. This preset may have a
very different name than the name of your format. This is OK.
You can easily modify a preset later with the 8300's one-knob L
feature. Refer to Section 3.
Congratulations! You are now on the air with your initial sound. Feel free to
read the material in Section 3 of this manual, which describes the various presets
and how you can customize them to achieve your desired signature sound.
19. Complete Station ID (optional).
The Station ID is an optional setting that you can provide to associate the 8300
with the station providing the program material (e.g., "Z-100"). The name can be
up to eight characters long. It is used to identify your 8300 to Orban's PC Remote
application, and it appears on the Main Screen when the 8300 is being controlled
by the PC Remote application.
A) Navigate to S
ETUP
B) Use the knob to set the each character in the ID. Use the N
tons to control the cursor position.
C) When finished entering your name, press the SAVE button. If you escape to
the main screen from Setup, you can now see the station name toggle on the
main screen.
20. Activate the 8300's ITU-R 412 controller (optional).
[Skip this step if ITU-R 412 is not enforced in your country. At the time of this
writing, it is only enforced in certain European countries. If your country does
not enforce ITU-R 412, set the ITU412-9 control to OFF.]
A) Navigate to S
ETUP
B) Set the multiplex power threshold by holding the ITU412-9 button down and
turning the knob so that the display indicates 0.0 dB.
If your transmission system introduces overshoot in the signal path after
the 8300 (including the transmitter), set the multiplex power threshold so
that it equals the amount of peak overshoot (in dB) in the transmission
system. If you do not do this, the 8300's ITU-R 412-9 controller will set the
average multiplex power too low.
The easiest way to measure system overshoot is to turn the multiplex
power controller off temporarily. Then set the 8300's output level (using
its built-in 400Hz reference tone) so that the transmitter produces 75
kHz deviation. Finally, play program material with lots of high frequency
energy and bass transients (like bright rock music with heavy kick drum)
