10 The Advanced MCACC menu
• Advanced EQ Setup – Use this to select the time
period that will be used for frequency adjustment and
calibration, based on the reverb measurement of
your listening area. Note that customizing system
calibration using this setup will alter the settings you
made in Automatically setting up for surround sound
(Auto MCACC) on page 39 or Automatic MCACC
(Expert) on page 73 and is not necessary if you're
satisfied with these settings.
3 If you selected 'Reverb Measurement', select EQ
ON or OFF, and then START.
The following options determine how the reverb
characteristics of your listening area are displayed in
Reverb View and Output PC (see Connecting a PC for
Advanced MCACC output on page 34):
• EQ OFF – You will see the reverb characteristics of
your listening area without the equalization
performed by this receiver (before calibration).
• EQ ON – You will see the reverb characteristics of
your listening area with the equalization performed
by this receiver (after calibration).
response may not appear entirely flat due to
adjustments necessary for your listening area.
When the reverb measurement is finished, you can select
Reverb View to see the results on-screen. See
Professional Calibration EQ graphical output on page 97
for troubleshooting information.
4 If you selected 'Reverb View', you can check the
reverb characteristics for each channel. Press RETURN
when you're done.

Note
1 • The calibration corresponding to the currently selected MCACC preset will be used when EQ ON is selected. To use another MCACC preset,
exit the HOME MENU and press MCACC to select it before pressing HOME MENU.
• The predicted reverb characteristics after calibration can be acquired with the Full Auto MCACC function (Automatically setting up for
surround sound (Auto MCACC) on page 39), but here the actually measured reverb characteristics after calibration can be acquired.
2 After auto calibration with EQ Type : SYMMETRY (Full Auto MCACC, etc.), the graph for the inferred reverb characteristics can be displayed
by selecting Reverb View. To display the actually measured reverb characteristics after EQ calibration, measure with EQ ON.
3 The 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.
4 The 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.

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.
Note that the markers on the vertical axis indicate
decibels in 2 dB steps.
5 If '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 30-50ms setting.

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.
