How to Interpret the Graphs (Continued)
About the types of displays of the graph for the reverb characteristics after
EQ calibration
For “SYMMETRY” or “FRONT ALIGN”
• The display type is set to “Pair Ch” ( page 9 ). For reasons of the properties of the different EQ curves, when
the “Each Ch” display type is set, the reverb characteristics for the different channels do not line up properly.
• The reverb characteristics prior to calibration are displayed in the “Each Ch” mode, so if you want to
compare the characteristics before and after calibration, set the display type prior to calibration to “Pair
Ch”. This way the number of channels before and after calibration are the same, allowing you to compare.
For “ALL CH ADJ”
• The display type is set to “Each Ch” ( page 9 ). For reasons of the properties of the EQ curves, when the
“Pair Ch” display type is set, the reverb characteristics for the different pairs of channels do not line up
properly.
• Since the “Each Ch” display type is set both before and after calibration, the graphs can be compared as
such.
Displaying the reverb characteristics after EQ calibration
(actually measured values)
The graphs for before and after calibration can be displayed at the screen displaying the graphs of the
reverberation characteristics after Full Auto MCACC (EQ Type:SYMMETRY) measurements, but note that the
graph displayed here for the characteristics after calibration is a prediction of the reverb characteristics after
MCACC calibration. If you want to check the graph of the actually measured reverberation characteristics
after MCACC calibration (not the prediction), you must re-measure the reverb characteristics after calibration.
To do so, follow the procedure described below. If the “Full Auto MCACC” operation has never been
performed, conduct the “Full Auto MCACC” operation here. (See the receiver’s Operating Instructions.)
1
Select the “EQ Professional” option for “Manual MCACC”, and perform with
“Reverb Measurement” set to “EQ ON”. (See the receiver’s Operating Instructions.)
Measure the room’s reverb characteristics after equalization with the microphone at the same position as
when the “Full Auto MCACC” operation was performed. The measurements are performed with the EQ
values stored in the MCACC memory selected on the receiver, so before measuring the reverb
characteristics, select the MCACC memory to be measured after equalization.
2
After the “Full Auto MCACC” operation is completed, press the “HOME MENU”
button to close the home menu.
The measurement data is prepared to be sent at the point that the home menu is closed.
3
Launch AVNavigator on the computer.
4
From the AVNavigator menu, select “Settings”, then select the “MCACC Data” tab.
5
Specify the “MCACC Data Storage Folder”.
The measurement is saved in the folder specified here. The folder in which the data is saved can be
changed by pressing “Change”.
6
From the AVNavigator menu, select “MCACC Appli” to launch MCACC Application.
When the MCACC application is launched, the “MCACC data” screen appears simultaneously.
7
Follow the instructions on the “MCACC data” screen to download the data
measured in step 1.
The data measured in step 1 is transferred to the folder specified in step 4.
8
Select the “.mcacc” file stored on the computer, then select “Open”.
You can display the graph of the reverberation characteristics actually measured after EQ calibration by
displaying the Reverb graph and selecting “After”.
