11 The Advanced MCACC menu
! 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.
— The calibration corresponding to the
currently selected MCACC preset will be
used when EQ ON is selected. To use
another MCACC preset, press MCACC to
select the MCACC memory you want to
store.
— 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.
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 72 for troubleshooting
information.
4 If you selected ‘Reverb View’, you can
check the reverb characteristics for each
channel. Press RETURN when you’re done.
The reverb characteristics are dis-
played when the Full Auto MCACC or
Reverb Measurement measurements are
conducted.
Use
k/l to select the channel, frequency
and calibration setting you want to check. Use
i/j to go back and forth between the three.
The reverb characteristics graph before and
after EQ calibration can be displayed by select-
ing 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.
! To specify the place where the MCACC
memory is to be stored, press MCACC to
select the MCACC memory you want to store.
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 mea-
surement 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
k/l to select the setting. Use i/j 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 set-
tings on-screen.
