The reverb characteristics are displayed when the Full Auto MCACC or Reverb Measurement measurements are conducted.1

Use / to select the channel, frequency and calibration setting you want to check. Use / to go back and forth between the three. The reverb characteristics graph before and after EQ calibration can be displayed by selecting Calibration : Before / After.2 Note that the markers on the vertical axis indicate decibels in 2 dB steps.

5If ‘Advanced EQ Setup’ is selected, select the MCACC memory to be stored, then enter the desired time setting for calibration, and then select START.

Based on the reverb measurement above, you can choose the time period that will be used for the final frequency adjustment and calibration. Even though you can make this setting without reverb measurement, it is best to use the measurement results as a reference for your

time setting. For an optimal system calibration based on the direct sound coming from the speakers, we recommend using the 30-50mssetting.

Use / to select the setting. Use / to switch between them.

Select the setting from the following time

periods (in milliseconds): 0-20ms, 10-30ms, 20-40ms, 30-50ms, 40-60ms, 50-70msand 60-80ms. This setting will be applied to all channels during calibration.

When you’re finished, select START. It will take about 2 to 4 minutes for the calibration to finish.

After the Acoustic Calibration Equalization is set, you are given the option to check the settings on-screen.

Note

1The After display when measurements have been made using the Full Auto MCACC or Auto MCACC (ALL) function shows the graph for the inferred reverb characteristics after EQ Type : SYMMETRY calibration.

2The reverb characteristics graph is overwritten each time the reverberations are measured. No Data is displayed if there is no reverb characteristic data, for example before measurements have been taken.
