■ EQ Professional
You can automatically measure and calibrate the reverberation characteristics (how the
sound echoes) of the room. First measure the reverberations with "Reverb Measurement",
then check the results with "Reverb View". Specify the calibrated time position in
"Advanced EQ Setup" based on the measured results to automatically calibrate the
reverberation characteristics.
Reverb Measurement :
Measure the reverberation characteristics of the room. After making the following settings,
place the speaker setup microphone in the listening position, and connect to the MCACC
SETUP MIC jack on the main unit. Press ENTER and follow the on screen instructions.
Setting Item Default Value Setting Details
Reverb Measure without EQ Select the method for measuring the reverberation
characteristics.
"without EQ": MCACC is used to measure the
reverberation characteristics of the room without
any adjustments made to the equalizer of the
speakers.
"with EQ": Measures the reverberation
characteristics of the room using the adjustments
to the equalizer of the speakers saved in the
MCACC Memory.
Reverb View :
The results of the measurements of the reverberation characteristics are shown in graphs
for each speaker and frequency. If there is no reverberation, the graph stays horizontal, but
if there is reverberation the graph rises to the right. If the "Symmetry" calibration type has
been selected and Full Auto MCACC was performed, predicted values for the reverberation
characteristics after calibration are also shown.
Advanced EQ Setup :
Reverberation characteristics are automatically calibrated according to the settings made.
After making the following settings, place the speaker setup microphone in the listening
position, and connect to the MCACC SETUP MIC jack on the main unit. Press ENTER and
follow the on screen instructions.

Time Position 30 - 50 msec Specify the calibrated time position in the range
between "0 - 20 msec" and "60 - 80 msec" (10
msec intervals).
If the reverberation characteristics differ for each
frequency or each channel in the Reverb View
graph, we recommend selecting "30 - 50 msec". If
the overall reverberation characteristics are similar,
we recommend selecting "60 - 80 msec".
EQ Type Symmetry Select the calibration type.
"Symmetry": Speakers that make one set as a left
and right pair have their frequency characteristics
calibrated flatly. Speakers not in pairs, such as
the center speaker, are adjusted individually.
Select when you want to give weight to phase
characteristics for calibration.
"All Channel Adjust": Flatly calibrates individually
the frequency characteristics of all speakers.
Select when you want to give weight to frequency
characteristics for calibration.
"Front Align": Calibrates speakers other than
the front speakers so their characteristics match
those of the front speakers (front speakers are not
calibrated). Select when you want to give weight to
characteristics of the front speakers for calibration.
Standing Wave
Multi Position
No When you select "Yes", standing wave calibration
can be performed at two listening positions along
with the main listening position. If there is only one
listening position, select "No".
• If you select "Yes", calibration is first performed
for the locations other than the main position,
then the main position is calibrated last.
