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" ( → p147 ) 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.
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.
1. Start the Onkyo Controller and tap the unit when displayed.
2. Tap " " at the top left of the screen and select "Dirac Live".
3. Connect the supplied Speaker Setup microphone to the SETUP MIC jack on
the main unit.

• If the number of speaker channels set in "2. Speaker" - "Configuration"
- "Speaker Channels" ( → p115 ) in the Setup menu is different to the
number of connected speaker channels, an error is displayed and
measurement cannot be performed.
5. Select the method of measurement. There are two methods of measuring to
choose from; "Quick" which measures 3 locations; at the listening position
and to the left and right of the listening position; and "Full" which measures 9
positions including the listening position. Tap the method you prefer.
"Quick": Set up the microphone at ear height in the listening position for
measurement. Next measure by setting up the microphone between 50 and
100 cm away to the left and right of the listening position.
"Full": Set up the microphone at ear height in the listening position for
measurement. Next, measure in 8 positions to the front, back, left, right, etc.,
centered on the listening position. Measure by setting up the microphone
in each of these positions, between 50 and 100 cm away from the listening
position.
