Profiles

For each Theater, Sub-Theater, and zone, you
can save multiple profiles for different listening
preferences. Profiles can be recalled as part of
presets "Presets" on page 28. A profile includes
the following information: Speaker definition (multi-
way, levels, delays), bass management, manual EQ,
and Dirac filter design if applied.
Some clients have different EQ profiles based on the
type of content they listen to e.g. movies vs. music.

1. Rename
By default, one profile is created called New
Profile 1. You can rename this to something
more descriptive.
2. New
Click New to build a new profile from defaults.
3. Duplicate
Build a variation on a saved profile. This is
especially useful if you have a profile designed
with Dirac Live. Since you cannot edit Dirac
reference profiles directly, you can build a
duplicate and edit that duplicate.
4. Save
After any changes to a profile or creation of a
new one, you must SAVE your changes.
