   NOTE
   • The internal microphone of the computer and other recording devices connected by USB are also displayed. Be sure to select the microphone you connected for these measurements.

6. Adjust the output level for the measurements and the input level for the microphone.
   Adjust the output of all of the speakers that are connected to a suitable level so that proper measurements can be taken. 1 Put the microphone you will use for the measurements on the microphone stand and place the stand at the main listening point.
   Point the tip of the microphone toward the ceiling and adjust the height to match the height of the ears of a listener in a seated position.
   2 Set Mic gain to 100%.
   3 Set Master output to around -55.0dB.
   4 Select one speaker and press the p button.
   A test tone will be output from the speaker you selected and the audio that is detected will be displayed on a level bar.
   5 Adjust the master output so that the audio that is detected is around -15.0dB to -30.0dB.
   6 Play the test tone of the next speaker and check that the output displayed in the level bar is between -15.0dB and -30.0dB.
   If it is outside this range, adjust the output level using the volume controls for each channel in the Dirac Live software.
   7 Repeat step 6 for all of the speakers and adjust each speaker so that the output level is between around -15.0dB and -30.0dB. When you have finished adjusting the output levels, click “Proceed to Select Arrangement”.
   NOTE
   • The output displayed on the level bar is a guide only, and the level bar may not reach -30dB depending on your computer or environment. In this case, adjust all channels to approximately the same level.
   Set the volume level a little higher than the level you would typically use.
   ** About the main listening position
   • The main listening position is the position where listeners would normally sit or where one would normally sit alone within the listening environment.
   •** To ensure that the measurement results are correct, put the microphone for measurement on a microphone stand.

   6 Repeat steps 4 and 5 to take measurements in all of the positions.
   When you have finished taking the measurements, click “Proceed to Filter Design”.
   NOTE
   • You can proceed to the next step (“Filter Design”) without taking measurements in every position. However, we recommend taking measurements in every position, because the more measurements that are taken, the more accurate the calibration is.
   • Keep the room as quiet as possible during measurements. Other noise will interfere with measurements. Close the windows and turn off electrical products (radios, air conditioners, fluorescent lights, etc.) Noise from these products may affect measurements.
   • Do not stand between the speakers and the microphone or place large items there while taking measurements.

9. Adjust the filters.
   Adjust the filters of each channel.
   Filter options
   The features of the filter options that can be selected in Dirac Live software are as follows.
   • “Dirac Live” is a digital room correction technology that employs a sophisticated analysis of your speakers and listening room.
   • “Bass Management” directs bass frequencies from all input channels to one or more subwoofers.
   • “Bass Control” is a measurement based bass management where both speakers and subwoofers are viewed as a complete system.

   When you have finished adjusting the filters, click “Proceed to Filter Export”.
   Bass Control and Bass Management
   The filters that can be used will differ depending on your license.
   • Bass Control is fundamentally different from traditional bass management solutions. Bass Management is a common AVR function that extracts bass content from input signals and routes it to connected subwoofers.
   Bass Control does offer bass management functions, but the core value of Bass Control is that it co-optimizes speakers to improve bass accuracy and ensures consistent bass performance throughout the listening area from a single- or multiple-subwoofer setup. Put simply, each subwoofer is tuned as part of a complete unit in your listening space, leading to a consistent and realistic response, no matter the arrangement.
   • For more details on Dirac Live, see Dirac Live Support.
   https://helpdesk.dirac.com/
   NOTE
   • The optimal “Distances”, “Levels” and “Crossovers” are calculated by the Dirac Live software when Bass Management or Bass Control™ is set as the filter option.

Tips

Troubleshooting
Frequently asked questions

Where can I purchase a Dirac Live license?

• You can purchase a Dirac Live license on the Dirac website (www.dirac.com/marantz).

Can I apply Dirac Live to multiple AVRs with one Dirac Live license?

• No. Dirac Live licenses are registered to the AVR itself. To apply Dirac Live to multiple AVRs, you will need to purchase a license for each AVR. My AVR is not detected by the Dirac Live software. • Make sure your AVR and your computer are connected to the same network and that both can connect to the internet. “Connect to a network.” (v p. 7 ) • Restart the Dirac Live software. • Restarting the device may improve the problem. Continue pressing the X button on the unit until “Restart” appears in the display, or remove and re- insert the power cord of the unit. • Your router or its settings may be incompatible with the Dirac Live software or your AVR. Use a different router or check the settings of your router.

Can Dirac Live measure crossover frequencies?

• Dirac Live Room Correction does not support automatic measurement of crossover frequencies. You will need to manually configure the settings in the AVR setup menu before or after measuring. • You can use the additional Dirac Live Bass Control or Bass Management function to automatically set crossover frequencies. You can also adjust them in the Filter Design screen. “9-2 If using Bass Management or Dirac Live Bass Control™” (v p. 14 )

Can target curves be edited offline?

• No. Your AVR needs to be connected to your computer to edit target curves. An error message is displayed in the Dirac Live software. • Make sure the Dirac Live software is updated to the latest version. To check whether you are using the latest version, go to: www.dirac.com/live/downloads/ I can't use Dirac Live filters. • Dirac Live filters can be set in “Setup Menu” - “Audio”

• “Dirac Live” or “Option Menu” - “Dirac Live”. “Setting up Dirac Live on this unit” (v p. 18 )

I can’t find the Dirac Live filter(s) stored on my AVR anymore.

• Your Dirac Live filter(s) are automatically deleted on your AVR if you change your AVR’s speaker configuration. For example, if you modify the Speaker Layout settings on your AVR, your filter(s) will be deleted. To recover your filter(s): Dirac Live filters do not work if the speaker configuration has been changed. You can either create new Dirac Live filter by performing a new Dirac Live calibration, or you can change your AVR’s speaker configuration back to the initial Dirac Live calibration that the filter(s) were built for. If you go back to your previous Dirac Live calibration, you can access your original Dirac Live filter(s) stored on your PC and export again to your AVR.

What does the “Device data inconsistent or unsupported” error message on Dirac Live software mean?

• You will see this error message when the speaker configuration on your AVR has been changed. The Dirac Live software sees that the speaker configuration on your AVR doesn’t match its stored configuration. To troubleshoot this error, do one of the following: - Set the speaker configuration back to the original. - If you want to keep the new speaker configuration, you must reinitiate the Dirac Live calibration process to create new filters. If you’re sure that the speaker configuration has not been changed, but you’re still getting the error message, try power cycling your AVR to see if the error message disappears. To power cycle, press and hold the AVR’s power button for more than 5 seconds or unplug and plug back in the AVR.

Device data inconsistent or unsupported
The connection was refused due to the device reporting data that is either inconsistent or insufficient for use with Live.

Can I connect my PC to my AVR and perform Dirac Live calibration on my TV?

You can connect your PC to your AVR via HDMI. However, once Dirac Live calibration starts, the AVR outputs the Dirac status screen (the image shown below) on your TV until the calibration finishes. You cannot continue to see your PC screen on your TV. You must use a separate PC monitor or a laptop for the calibration.

Can I use Dirac Live when my AVR is using pre-outs?

Yes.

Can I use the Dirac Live iOS or Android app instead of the Dirac Live software for PC or Mac?

Yes. However, during calibration, the app will not accept the built-in microphone on your iOS or Android device. Please have your choice of USB microphones, such as Mini DSP’s UMIK-1, ready and connected to the AVR’s front panel USB input to perform calibration. Invalid recording device. CINEMA 40 was selected to record measurements but has no recording capabilities. Dirac Live requires a microphone connected to the audio device. Dismiss

Can I use the Dirac Live Bass Control function with a Dirac Live Room Correction license?

No. You will need to purchase a Dirac Live Bass Control license in addition to your Dirac Live Room Correction license. “Dirac Live licenses and features” (v p. 6 )

Can I combine a Dirac Live Bass Control license with the Limited Bandwidth license for Dirac Live Room Correction?

Yes. You can combine it with the Dirac Live Rooms Correction Full Bandwidth license and the Limited Bandwidth license.

How can I tell if my Bass Control license is registered to my AVR?

Use the Dirac Live software to connect to your AVR.　You can see Dirac Live Options that are available to you when you open the Filter Design Page. It is not possible to use your TV screen to check whether your AVR is registered for Bass Control.

Do I need to take measurements again in order to use Dirac Live Bass Control?

If you have the project file from the last time you took measurements, you can simply load the project file in the Dirac Live software and skip the measurement. You can create a new Bass Control filter based on your previous measurement results. “Creating a filter using an existing project file” (v p. 17 )

I can't change the speaker settings.

Some speaker settings cannot be configured when using a filter where Dirac Live Bass Control is applied. To use these settings, turn off Dirac Live or select a filter where Dirac Live Room Correction is applied. “Setting up Dirac Live on this unit” (v p. 18 )
