Optimod-AM 9400 V1.2 Operating Manual - Orban

OPERATION ORBAN MODEL 9400
listening through radios to a wide variety of speech and music programming at
NRSC and 5.0 kHz bandwidths. There are significant differences between the wideband
and narrowband tables in both the equalization and dynamics processing.
The low-pass filter frequency in the active Transmission Preset determines which set
of parameters are active in any on-air Factory Preset. Recalling a Transmission preset
that switches the HF bandwidth between ranges will also update the parameters of
any active Factory Preset automatically. However, changing the HF bandwidth will
not change the parameters of an active User Preset or modified Factory Preset because
these kinds of presets have only one set of parameters: the parameters visible
in Advanced Modify (see below).
Full Modify
Full Modify is the most detailed control level available from the 9400’s front panel. It
allows you to adjust the dynamics section at approximately the level of “full control”
available in Orban’s 9200 processor. These controls are somewhat risky (although
not as much as the controls in Advanced Modify). Most people will never
have any reason to go beyond Full Modify, even if they want to create a “signature
sound” for their station.
Note: Full Modify does not provide LESS-MORE control. Furthermore,
once you have edited a preset’s multiband dynamics parameters in Full
Modify or Advanced Modify, LESS-MORE control is no longer available in
Basic Modify and will be grayed-out if you access its screen. As noted
above, we recommend using the Basic Modify LESS-MORE control to
achieve a sound as close as possible to your desired sound before you
make further modifications at the Full or Advanced levels.
Editing the Full or Advanced Modify controls in one processing channel
(analog AM or digital) only defeats the LESS-MORE control for that channel
because the LESS-MORE controls in the analog and digital processing
channels are independent. You can still use LESS-MORE in the remaining
channel if you have not edited that channel’s Full or Advanced controls.
Advanced Modify
If you want to create a signature sound for your station that is far out of the ordinary
or if your taste differs from the people who programmed the LESS-MORE tables,
Advanced Modify is available to you from the 9400 PC Remote software only
(not from the 9400’s front panel). At this level, you can customize or modify any subjective
setup control setting to create a sound exactly to your taste. You can then
save the settings in a User Preset and recall it whenever you wish.
Maladjustment of these controls can cause the 9400 to produce unexpected distortion
or artifacts only on certain program material, even though it might sound good
on most other material. Placement of a control in the Advanced Modify group emphasizes
the risk of adjusting this control casually.
