• OPTIMOD-DAB Audio Processor contains a built-in line-up tone generator, facili-
tating quick and accurate level setting in any system.
Presets in OPTIMOD-DAB
There are two distinct kinds of presets in OPTIMOD-DAB: Factory Processing Presets
and User Presets.
Factory Processing Presets
There are 36 Factory Processing Presets — 26 for radio and 10 for television. These are
our “factory recommended settings” for various program formats or types. The descrip-
tion indicates the processing structure and the type of processing. Each Factory Process-
ing Preset on the Recall Preset list is really a library of 20 separate presets, selected by
pressing the
Modify
button and using the
LESS-MORE
control to adjust OPTIMOD-DAB
for more or less processing.
Factory Processing Presets are stored in OPTIMOD-DAB’s non-volatile memory and
cannot be erased. You can change the settings of a Factory Processing Preset, but you
must then store those settings as a User Preset, which you are free to name as you wish.
The Factory Preset remains unchanged.
User Presets
User Presets permit you to change a Factory Processing Preset to suit your requirements,
and store those changes.
You may store up to 32 User Presets. They are indicated on the Recall Preset list by a
number designation from 01 to 32, followed by a description.
You may enter in any description you wish, up to 16 characters. User Presets cannot be
created from “scratch.” Start by recalling a Factory Preset. You can then immediately
store this in a User Preset, give it whatever name you wish, then make changes to the
settings. Or you can recall a Factory Preset, make the changes first, and then store this in
a User Preset.
Either way, the Factory Preset remains for you to return to if you wish.
User Presets are backed up in EEPROM, which is a form of rewritable mem-
ory that does not require battery backup. So your presets are safer than they
would be if the memory required battery backup.
You can also modify an existing User Preset.
