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 & Full Band Phase Control)
on page 46
or
Automatic MCACC (Expert)
on page 110 and is not
necessary if you’re satisfied with these settings.

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 41):
•
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).
1
Note that the EQ
response may not appear entirely flat due to
adjustments necessary for your listening area.
2
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 137
for troubleshooting information.

If you selected ‘Reverb View’, you can check the
reverb characteristics for each channel. Press RETURN
when you’re done.
The reverb characteristics are displayed when the
Full
Auto MCACC
or
Reverb Measurement
measurements
are conducted.

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.
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
,
50-70ms
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.
Precision Distance
(SC-27 only)
Before using this function, perform the Full Auto MCACC
Setup procedure (see page 46). Performing the Full Auto
MCACC procedure corrects the distance to a precision of
1
/
2
inch, but the Precision Distance function lets you
adjust the distance to the speakers (their position) with a
precision of under
1
/
2
inch. Here, rather than correct the
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

and press

.
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
