TX-NR7100 - Dirac Live
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. 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.
- Start the Onkyo Controller and tap the unit when displayed.
- Tap
at the top left of the screen and select "Dirac Live".
- Connect the supplied Speaker Setup microphone to the SETUP MIC jack on the main unit.
- Tap "Next", confirm that the displayed speaker configuration is correct, then tap "Next".
If the number of speaker channels set in "2. Speaker" - "Configuration" - "Speaker Channels" in the Setup menu is different to the number of connected speaker channels, an error is displayed and
measurement cannot be performed. - 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. - The guidance about outputting the test tone is displayed. Refer to the illustration to set up the speaker setup microphone in the listening position. Follow the on-screen instructions to measure.
Measurement may not be possible if the test tone is to loud or too soft. Tap "Level Adjust" to adjust the volume of the test tone. - When measurement is complete, "Calculating results" is displayed on the screen. Tap "Transfer to your product" to transfer the measurement data to the unit.
- Disconnect the speaker setup microphone.
When Dirac Live is used for measurement, the measurement results are also reflected in "2. Speaker" - "Distance" in the Setup menu, and you will no longer be able to change the values. (The setting units are displayed as "msec".)
Using Dirac Live
You can use the equalizer function based on the measurements results of Dirac Live. From "Room EQ" - "Dirac Live" in "Quick Menu", select from "Slot1" to "Slot3". Note that the same data is saved in all of the slots, but you are able to create your own original sound quality in the following "Manual Adjust"
section.
- In the Setup menu, when the number of speaker channels, etc., is changed in "2. Speaker" - "Configuration" ( →p115), the measurement results are deleted.
- When using Dirac Live, signals with a sampling frequency of 32 kHz are not supported.
Manual Adjust
You can adjust the sound quality to your own original one by modifying the equalizer curves based on the volume level of the speakers automatically measured with Dirac Live. Modify the equalizer on the Onkyo Controller.
- To adjust the sound quality with "Manual Adjust", it is first necessary to
measure the speakers of this unit with Dirac Live. - This function cannot be used when speaker measurement is done with AccuEQ Room Calibration.
Modifying the Equalizer
- Start the Onkyo Controller and tap the unit when displayed.
- Tap
in the top left of the Onkyo Controller screen to display a list of menus, then tap "Manual Adjust".
- Select the slot to modify from "Slot1" to "Slot3", then tap "Next".
The measurement results from Dirac Live are registered in all of the slots as the default values. - After selecting the speaker to adjust first, modify the equalizer curve.
- When adjustment is finished, tap 4 to recalculate, then tap 5 to transfer the adjusted data to the unit.
- In the Setup menu, when the number of speaker channels, etc., is changed in "2. "Speaker" - "Configuration", the adjusted content is deleted.
Using an Equalizer you have Registered
When you select a saved slot in "Room EQ" - "Dirac Live" in Quick Menu, you can use the registered equalizer.
