Dirac Live
Dirac Live ® is an advanced room correction technology developed by Dirac
Research. As one of the most advanced room correction technology available
on the market, Dirac Live helps listeners to correct for one of the weakest
components in the audio chain: the listening room. Dirac Live not only corrects
the frequency response, but also the impulse response of the loudspeakers in a
room, yielding improved imaging and timbre, better clarity, tighter bass, and less
early reflections, as well as reduced resonances and room modes.
Additional Functions
Dirac Live Bass Control
Dirac Live Bass Control is a technology to manage low-frequency channel
routing from the signal to the playback channels (speakers) of your audio
device. Additionally, with full control over the device's channel and frequency
routing and output, the Dirac Live room correction technology is significantly
augmented. In particular systems with multiple subwoofers will see a
substantially improved room correction and bass performance.
To use Dirac Live Bass Control, you need to register with Dirac Live and obtain
a Dirac Live Bass Control license. For details, refer to the Dirac Live website.

Measuring with Dirac Live
Use the Onkyo Controller to use Dirac Live to take measurements. Use the most
recent version. Note that you cannot make settings using operations on this unit.
Refer to "Onkyo Controller" ( →p169) for information about the app. Also have
a tripod ready to set up the speaker setup microphone.
• Calibration takes about 20 minutes to be completed.
1. Start the Onkyo Controller and tap the unit when displayed.
2. Connect the supplied speaker setup microphone to the SETUP MIC jack on
the main unit.
3. Tap "Yes", confirm that the displayed speaker configuration is correct, then
tap "Yes".
• If the number of speaker channels set in "Speaker" - "Configuration"
- "Speaker Channels" ( →p133) in the Setup menu is different to the
number of connected speaker channels, an error is displayed and
measurement cannot be performed.
4. Select whether to use Dirac Live Bass Control. Select "Use" to use it and log
into Dirac Live.
5. Select the method of measurement. There are two methods of measuring
to choose from; "Quick Measurement" which measures 3 locations; at the
listening position and to the left and right of the listening position; and "Full
Measurement" which measures 9 positions including the listening position.
Tap the method you prefer.
"Quick Measurement": Set up the microphone at ear height in the listening
