If the pattern is as shown above, select the 30-
50ms setting. If not, this setting is not
necessary.
Note
1 If the Reverb View procedure is performed after the Automatically setting up for surround sound (Auto MCACC) on
page 40 or Reverb Measurement operation, depending on the standing wave control setting, differences may
appear on the reverb graph. With the Auto MCACC function, the reverberations are measured with the standing waves
controlled, so the reverb characteristics graph shows the characteristics with the effect of the standing waves
eliminated. By contrast, the Reverb Measurement function measures the reverberations without controlling the
standing waves, so the graph indicates the reverb characteristics including the effect of the standing waves. If you
wish to check the reverb characteristics of the room itself (with the standing waves as such), we recommend using
the Reverb Measurement function.

Using Acoustic Calibration EQ Professional
1 Select 'EQ Professional', then press
ENTER.
2 Select an option and press ENTER.
• Reverb Measurement – Use this to
measure the reverb characteristics of your
room.
• Reverb View – You can check the reverb
measurements made for specified
frequency ranges in each channel.
• 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 40 or
Automatic MCACC (Expert) on page 89 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:
• EQ OFF – You will see the reverb
characteristics of your listening area
without the equalization performed by this
receiver (before calibration).
