that we withhold from users. Our “secrets” are revealed in this manual and the pre-
sets embody all of our craft as processing experts. The presets are editable because
other sound designers may have different preferences from ours, not because the
presets are somehow mediocre or improvable by those with special, arcane knowl-
edge that we withhold from most of our customers.
Start with one of these presets. Spend some time listening critically to your on-air
sound. Listen to a wide range of program material typical of your format and listen
on several types of AM radios (not just on your studio monitors). Then, if you wish,
customize your sound using the information that follows.
Each Orban factory preset has L
ESS-MORE capability. The table shows the presets, in-
cluding the source presets from which they were taken and the nominal L
ESS-MORE
setting of each preset. Some of the Five-Band presets appear several times under
different names because we felt that these presets were appropriate for more than
one format; these can be identified by a shared source preset name.
Important! If you are dissatisfied with the sound available from the fac-
tory presets, please understand that each named preset is actually 19 pre-
sets that can be accessed via the L
ESS-MORE control. Try using this control
to trade off loudness against processing artifacts and side effects. Once
you have used L
ESS-MORE, save your edited preset as a User Preset.
Do not be afraid to choose a preset other than the one named for the type of pro-
gramming on-air if you believe this other preset has a more appropriate sound. Also,
if you want to fine-tune the frequency balance of the programming, feel free to use
Basic Control and make small changes to the Bass, Mid EQ, and HF EQ controls. Un-
like some earlier Orban’s processors, the 9300 lets you make changes in EQ, AGC,
and stereo enhancement without losing the ability to use L
ESS-MORE settings.
Of course, LESS-MORE is still available for the unedited preset if you
want to go back to it. There is no way you can erase or otherwise dam-
age the Factory Presets. So, feel free to experiment.
Description of the Factory Presets
Presets with “HF” in their names are narrowband presets intended for international
shortwave transmission where 4.5 kHz audio bandwidth and difficult propagation
conditions are the norm. All other presets are intended for medium wave
transmission.
GENERAL PURPOSE MEDIUM is the default factory preset. It is based on the
Medium-Fast multiband release time and is adjusted to sound equally good on voice
and music. It is most appropriate for listeners in strong signal areas because it does not
bring up low-level material as much as presets based on the Fast multiband release
time.
GENERAL PURPOSE HEAVY is based on the Fast multiband release time, and is
designed to sound good on voice and music. Because it processes harder than the
G
ENERAL PURPOSE MEDIUM preset it can be louder but does not sound as punchy or
dynamic. It is a good choice when many listeners are subject to noise and interference
and you want the highest possible loudness.
