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 (Data Management):
• 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 86
for troubleshooting information.
4 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 the /
buttons to select the channel and the frequency you want
to check. Use the / buttons to go back and forth
between the two. Note that the markers on the vertical
axis indicate decibels in 2 dB steps.
5 If ‘Advanced EQ Setup’ is selected, enter the
desired time setting for calibration. Press to
proceed to the next screen, 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 the / buttons to select the channel, frequency,
and time setting. Use the / buttons to switch
between them.
You can switch between your connected speakers
(excluding the subwoofer), and display the
measurements for the following frequencies: 63Hz,
125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz and
16kHz.
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.
Full Band Phase Control
The Full Band Phase Control feature calibrates the
frequency-phase characteristics of the speakers
connected and corrects the phase distortion. This
receiver analyzes the frequency-phase characteristics of
the speakers by calibrating test signals output from the
speakers with the supplied microphone, therefore
flattening the analyzed frequency-phase characteristics
during audio signal playback. This correction minimizes
group delay between the middle- and low-frequency
ranges and improves the frequency-phase
characteristics across all ranges. Furthermore, the
enhanced frequency-phase characteristics between
channels ensure better surround sound integration for
multichannel sources. For details, see Using Full Band
Phase Control on page 11.
This section describes how to calibrate the frequency-
phase characteristics of the speakers only. Once you
have performed calibration with Auto MCACC set as a
default setting or with CUSTOM set to ALL, the Full Band
Phase Control calibration is already done (In this case,
the previous settings are overwritten if you perform
calibration again as described here).
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
System Setup menu and
press MCACC to select it before pressing SETUP
