4.4.2 Dirac Live Optimization
Dirac Optimization is an audio optimization process that requires setup by using a separate external
program running on a PC. The setup process creates a set of filter coefficients to improve sound based
on a set of measured responses from the listening area.
The RS20i supports two versions of Dirac which are referred to as Dirac 1 and Dirac 2 in the menus. The
Dirac 1 version is the original, while Dirac 2 is the latest and allows more flexibility in the setup process.
Dirac 1 must be used to support old installations, and switching to Dirac 2 is recommended when the
Dirac 2 installation software becomes available.
In order to use coefficients from the Dirac 1 setup program, the RS20i must be set for Dirac 1 in the
System > More screen. Likewise, in order to use coefficients from Dirac 2 setup, the RS20i must be set
for Dirac 2 in the System > More screen. Switching between Dirac 1 and Dirac 2 on the RS20i requires a
power reset. You will see one of two possible Dirac menus depending on the Dirac version after the
power reset.

Function Description
Enabled/Disabled
Toggle between enabling and disabling the Dirac Optimization.
Current Dirac
Configuration
Displays the name of the current Dirac configuration.
Select
Select a configuration from the list of saved configurations (gray box above),
then touch the Select button. This configuration will now become the current
Dirac configuration.
Delete
Select a configuration from the list of saved configurations (gray box above),
then touch Delete. The configuration will be deleted from the list and from the
memory of the RS20i.
