NOTE
If your unit has two USB ports, connect the microphone to the USB port on the front panel.
Select the microphone you will use for the measurements.
If the microphone you are using for the measurements comes with a calibration file, you will need to load the calibration file in the Dirac Live software too.
Click “No microphone calibration” of the microphone (shown in red) to load the calibration file.
After selecting the microphone, click “Proceed to Volume Calibration”.
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.
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.
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.
Set Mic gain to 100%.
Set Master output to around -55.0dB.
Select one speaker and press the 
button.
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.
Adjust the master output so that the audio that is detected is around -15.0dB to -30.0dB.
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.
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.
Select a listening area
After selecting the listening area, click “Proceed to Measure”.
NOTE
Use the “Wide Imaging” arrangement in Dirac Live if your room has more than one row of seating or is large enough for more than two people.
Take the measurements.
Take measurements in each position.
Put the microphone you will use for measurement in the main listening position and point it straight upward.
Select the circle in the center of the illustration on the screen.
Click “Measure Selected position”.
A test tone will be output from each speaker and the measurement will start.
When the measurement is finished, move the microphone to the next position.
Select the next position on the screen and take the measurement.
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.

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.
9-1 If using Dirac Live Room Correction
Filter options
To use Dirac Live Room Correction as the filter design, select Dirac Live®. Filters are calculated after they are selected, so it may take a while for the full results to be displayed.
Target curve
The target curve is the curve used to decide the frequency characteristics of the speakers after calibration by Dirac Live. You can adjust the target curve according to your preferences.
Curtains
Use the sliders on the screen to adjust the frequency range across which the filter will be applied.
Speaker selection
Select the speaker for which you want to edit the target curve. You can also group together specific speakers. The same target curve will be applied to all of the speakers in the group.
When you have finished adjusting the filters, click “Proceed to Filter Export”.
NOTE
“Crossovers” are not calculated by the Dirac Live software when Dirac Live is set as the filter option. Set them manually on the unit if necessary.

Speaker selection
Select speakers to edit the target curve and crossover point. You can also exclude a group of speakers from Bass Management or Bass Control by dragging them to Unmanaged Channels.
Crossover point
Adjust the crossover frequency of the selected group of speakers.
A, defines which frequencies are assigned mainly to the subwoofers.
B, both subwoofers and high-range speakers will receive the frequencies.
C, defines the frequencies that are assigned mainly to the high-range speakers.
Calculate (Bass Control™ only)
If Bass Control™ is selected as the filter option, press the Calculate button to calculate the filter.
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.
