Orban 5750 Technical Manual Operation 3-13
Customizing the 5750’s Sound
Gain Reduction Metering
Unlike the metering on some processors, when any THE OPTIMOD-5750 gain reduction meter indicates full-scale (at
its bottom), it means that its associated compressor has run out of gain reduction range, that the circuitry is being
overloaded, and that various nastinesses are likely to commence.
Because the various compressors have 25 dB of gain reduction range, the meter should never come close to 25 dB
gain reduction if THE OPTIMOD-5750 has been set up for a sane amount of gain reduction under ordinary program
conditions.
To accommodate the FM pre-emphasis curve, Band 5 of the Five-Band Structure is capable of 30 dB of gain reduction.
Further, be aware of the different peak factors on voice and music—if voice and music are peaked identically on a
VU meter, voice may cause up to 10 dB more peak gain reduction than does music! (A PPM will indicate relative
peak levels much more accurately.)
To Create or Save a User Preset
Once you have edited a preset, you can save it as a user preset. The 5750 can store an indefinite number of user
presets, limited only by available memory.
• You cannot give a user preset the same name as a factory preset. If the name that you have selected
duplicates the name of a factory preset, a warning box will appear saying:
Factory Presets Cannot Be Overwritten
• If the name you have selected duplicates the name of an existing user preset, the 5750 warns you that
you are about to overwrite that preset. Answer YES if you wish to overwrite the preset and NO otherwise.
If you answer NO, the 5750 will give you an opportunity to choose a new name for the preset you are
saving.
You can save user presets from the 5750 HTML5 application. Please note that when you save presets from the
HTML5 application, you save them in the 5750’s memory (as if you had saved them from the 5750’s front panel).
When saving presets, do not use the term “Modified”. “Mod” or “modified” is OK. Attempting to save it as
“Modified” (with the letter M capitalized) is not allowed.
About the Processing Structures
If you want to create your own User Presets, the following detailed discussion of the processing structures is
important to understand. If you only use Factory Presets or if you only modify them with LESS-MORE, then you may
still find the material interesting, but it is not necessary to understand it to get excellent sound from the 5750
