Room EQ Wizard integration

REW import
Astral 16 offers the possibility to use external
Room Correction tool such as the Room EQ
Wizard (REW). REW offers very advanced
measurements and filtering capabilities where
you can define equalization and measure the
effect in both time and frequency domain. This
gives a total flexibility for Astral 16 users to go
from a fully automated approach with Dirac Live
to a fully manual approach that REW offers.
To allow for importing filters defined in the REW
tool, you must make sure that you first set the
REW tool for Focal Astral 16 compatibility.
Once done, you can then do your EQ for each
channel and export the equalization to a "*.txt"
file.
Select REW Import (1) and load the file
corresponding to the selected channel. The EQ
page will then be loaded with the REW defined
filters.
Note that you can define up to 12x Parametric EQ
and 2x High Pass or Low Pass filters (up to 48dB
slope.

Child Theater / Sub Theater

You may optionally create alternate speaker
definitions in your theater with some restrictions.
For example, if you wish to have music playing
before the movie plays before everyone is seated
and quiet, you might only want that music playing
from the overhead speakers so as not to interfere
with conversation. In this case, you can define
a child theater so that stereo left/right audio is
played only through the top speakers (as in the
example above).
Child theaters behave just like zones or main
theaters in that they can be selected as outputs,
programmed into presets and can have multiple
profiles.
Note that though multiple Child theaters can be
designed per main theater, signal assignment is
common to all.
1. Create Child
From the Main Speakers page, Edit your theater.
Click Create Child. A window will appear with a
list of loudspeaker names and their channel ID.
2. Zone Signal
For each loudspeaker, select the signal to be
played. You may choose Stereo Left, Stereo Right,
Mono, or None. Subwoofer channels can play
Subwoofer signal or None.
3. Keep Dirac Profile
If you have created a Dirac profile for the parent
theater, you have the option to retain that
calibration for the child theater.
4. Save/Close
Save when done, or Close to cancel.
5. Bass Management / Delay Level Phase
Child theaters have comparably limited options
compared to full theaters. If a child theater
includes a subwoofer channel, the full range
channels are forced to small. In this case, you
can adjust the crossover frequency, slope and
subwoofer subsonic filter. If no subwoofer channel
is enabled for the child theater, the main channels
are forced to large. No Expert Bass Management
is available for Child Theaters.
