Configuring AVR settings
Before using Dirac Live software, follow the steps below to set up this unit.
1 Connect to a network. Connect this unit and the computer where Dirac Live software is installed to the same network. (Setting items: Setup Menu - Network - Connection)
2 Set the speaker preset (excluding the first time measurement is performed). Select the speaker preset where you want to save the measurement results. If two speaker presets are already being used, the speaker preset you have selected will be overwritten with the measurement results. When performing calibration with Dirac Live for the first time, saving to Speaker Preset 2 is performed automatically. (Setting items: Setup Menu/Speakers/Manual Setup/Speaker Preset)
NOTE 0 When performing calibration with Dirac Live for the first time, the Speaker Layout
and Crossover values from Preset 1 are copied. 0 When performing calibration with Dirac Live for the first time, overwriting is
performed even when Preset 2 is in use.

3 Set the speaker layout. Set the layout of the speakers you want to measure in Speaker Layout in the menu. (Setting items: Setup Menu - Speakers - Manual Setup - Speaker Layout)
NOTE 0 The optional Dirac Live room correction feature calculates the proper gain and
delay time for each speaker, however it does not calculate the crossover points. Please adjust the crossover points for your speakers using the AVR's Setup Menu before performing Dirac Live calibration. Setting Item : Setup Menu Manual Setup Crossovers 0 The measurement cannot be conducted when headphones are connected. If headphones are connected, unplug them before performing the Dirac Live measurement.

A 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.
B Set Mic gain to 100%. C Set Master output to around -60.0dB. D 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. E Adjust the master output so that the audio that is detected is around -15.0dB to -30.0dB. F 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. G 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 0 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 0 The main listening position is the position where listeners would normally sit or
where one would normally sit alone within the listening environment. 0 To ensure that the measurement results are correct, put the microphone for
measurement on a microphone stand.

7 Select a listening area
.
After selecting the listening area, click "Proceed to Measure". NOTE 0 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.

A Put the microphone you will use for measurement in the main listening position and point it straight upward.
B Select the circle in the center of the illustration on the screen. C Click "Measure Selected position".
A test tone will be output from each speaker and the measurement will start. D When the measurement is finished, move the microphone to the next position. E Select the next position on the screen and take the measurement. F 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 0 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. 0 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. 0 Do not stand between the speakers and the microphone or place large items there while taking measurements.
