Tact-2.2 XP Auto Target Curve
In an effort to make automatically generated target curve feature more user
friendly, we have changed the auto target curve adjustment screen to include graphical
representation of the target curve changes. Auto target curve adjustment feature is active
only if AUTO option is set to AUTO-ON. If AUTO option is set to AUTO-OFF, 2.2 XP
will use computer generated target curve. For more details on computer generated ta rget
curve please see 2.2 XP help files.
Tact-2.2 XP can save up to seven room response measurements. These
measurements are saved in measurement files labeled as FILE: 1 through FILE: 7 (Fig.
3, field 4). Auto correction can use any of these measurement files to perform automatic
room correction. Auto correction screen (Fig. 3) is used to assign measurement files to
correction presets.
How does it work?
Using 2.2 XP measurements screen perform room response measurement as
described in 2.2 XP Automatic Room Correction documet. You can get this document
from the following link:

After the room response measurement is completed enter auto target curve screen as
described bellow.

Auto Target Curve Editor Screen
When in auto correction mode 2.2 XP will automatically generate left and right
channel target curve. This target curve is generated based on the measurement data
contained in the selected measurement file. Auto generated target curve is constant for a
given measurement file. Users have no access to this curve. In order to facilitate some on
the fly target curve modification 2.2 XP implements auto target curve editor screen as
displayed in Fig.4.
Auto target curve can be modified at 12 different frequency bands. These bands
can be selected using the frequency band pointer (5). This pointer can be moved to the
left and to the right side using remote control LEFT/RIGHT buttons. As the pointer
moves, fields (6) and (7) will display frequency and level of the selected frequency band.
Once, a band is selected use UP/DONW buttons to modify selected band level.
