The Advanced MCACC menu

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 70):

•

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).

Note that the EQ

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 114
for troubleshooting information.

If you selected ‘Reverb View’, you can check the

reverb characteristics for each channel. Press RETURN
when you’re done.

This appears according to the setting you chose in
Reverb Measurement (step 3 above). Use

/ to

select the channel and the frequency you want to check.
Use

/ to go back and forth between the three. Note

that the markers on the vertical axis indicate decibels in
2 dB steps.

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.

Use

/ to select the channel, frequency, and time

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, 50~70ms and 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.
