TX-RZ 30 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.
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 more information, see 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" ( →p143) 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" ( →p108) 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 position for measurement. Next measure by setting up the microphone between 50 and 100 cm (20" and 40") away to the left and right of the
listening position.
"Full Measurement": 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 (20" and 40")
away from the listening position.
6. 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 too loud or too soft.
Tap "Level Adjust" to adjust the volume of the test tone.
7. When measurement is complete, "Calculating results" is displayed on the screen. Tap "Transfer to your product" to transfer the measurement data to the unit.
8. Disconnect the speaker setup microphone.
• When Dirac Live is used for measurement, the measurement results are also reflected in "Speaker" - "Distance" ( →p111) 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 apply the filter curves adjusted based on the measurement results of Dirac Live. From "Room EQ" - "Dirac Live" ( →p75) 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 any filter curve you like in the following “Manual Adjust” section.
• In the Setup menu, when the number of speaker channels, etc., is changed in "Speaker" - "Configuration" ( →p108), the measurement results are deleted.
• When using Dirac Live, signals with a sampling frequency of 32 kHz are not supported.
Manual Adjust
You can modify the filter curve to one you like based on the volume level of the speakers automatically measured with Dirac Live. Edit the filter curve in Onkyo Controller.
• To adjust the sound quality with "Manual Adjust", it is first necessary to measure the speakers of this unit with Dirac Live ( →p140, p144).
• This function cannot be used when speaker measurement is done with AccuEQ Room Calibration ( →p142).
Modifying the filter curve
1. Start the Onkyo Controller and tap the unit when displayed.
2. Tap " " in the bottom of the Onkyo Controller screen to display a list of
menus, then tap "Manual Adjust".
3. 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.
4. After selecting the speaker to adjust first, modify the filter curve. The speaker currently being adjusted. To adjust another speaker, tap the
next to it and select another speaker.
Displays the Menu screen. From the menu, you perform actions such as reset the speaker adjustments and cancel and exit the adjustments. You can also copy data from other slots.
Drag the points on the filter curve side to side to change the frequency and up or down to change the boost.
• You can add a point by tapping on the curve where there isn't a point. Recalculate the characteristics from the adjusted content.
Transfer the adjusted content to the unit.
The value of the point being adjusted. Tap the " " next to the point to delete it.
• When the Dirac Live Bass Control is enabled, the bar for editing the crossover frequency is displayed. Adjust the crossover value by moving the bar side to side.
5. When adjustment is finished, tap to recalculate, then tap
to transfer the adjusted data to the unit.
• In the Setup menu, when the number of speaker channels, etc., is changed in "Speaker" - "Configuration", the adjusted content is deleted.
Using an filter curve you have registered
When you select a saved slot in "Room EQ" - "Dirac Live" ( →p75) in Quick Menu, you can use the registered filter curve.
