OPTIMOD SURROUND PROCESSOR INTRODUCTION

Factory Processing Presets
The Factory Presets are our “factory recommended settings” for various program
formats or types. There are multiple Factory Presets for both radio-oriented and
video oriented programming. Each Factory Preset on the Preset list is really a library
of more than 20 separate presets, selected by navigating to M
ODIFY PROCESSING >
LESS-MORE and using the LESS-MORE control to adjust OPTIMOD 8685 for less or
more processing. The factory presets are listed and described starting on page 3-23.
The description indicates the processing structure and the type of processing.
Factory
Presets are stored in OPTIMOD 8685’s non-volatile memory and cannot be
erased. You can change the settings of a Factory 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.
The surround and 2.0 processors do not have to use the same Factory Preset. To use
different presets, start by recalling your preferred Factory Preset for the surround
processing. Then “import” a different factory preset for the 2.0 processors and save
the result as a User Preset. This procedure is described in more detail below.
User Processing Presets
User Presets permit you to change a Factory Preset to suit your requirements and
then store those changes.
You can store more than 40 User Presets, limited only by available memory in your
8685 (which will vary depending on the version of your 8685’s software). You can
give your preset a name up to 18 characters long.
User Presets cannot be created from scratch. You must always start by recalling a
Factory Preset. Make the changes and then store your modified preset as a User Pre-
set. You can also recall a previously created user preset, modify it, and save it again,
either overwriting the old version or saving under a new name. In all cases, the
original Factory Preset remains for you to return to if you wish.
User Presets inherit the structure of their parent Factory Presets (Five-Band or Two-
Band). The only way you can choose the structure of a factory preset is to edit it
from a Factory preset having that structure (or to edit it from an older User Preset
having the desired structure). You cannot change an existing User Preset’s structure.
Presets contain parameters for both the surround and 2.0 processors. A preset,
whether Factory or User, can be edited in several ways to create a new User Preset.
You can adjust any individual parameter in the surround and 2.0 sections of the pre-
set. You can also bulk-import all of the 2.0 parameters contained in any User Preset
or Factory Preset.
User Presets are stored in non-volatile memory that does not require battery
backup. To Create or Save a Preset
on page 3-20 has more about User Presets. In-
structions for importing and editing a 2.0 preset are on page 3-25.
