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” (
). 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” (
). 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 Instruc-
tions.)
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
Select “Output MCACC data” from “MCACC Data Check”.
3
Connect your USB device to the USB terminal on the front panel, then select
“OK”.
4
Connect the USB device onto which the measurement data was transferred to
the computer’s USB port, then open the measurement data.
You can display the graph of the reverberation characteristics actually measured after EQ calibration by
displaying the Reverb graph and selecting “After”.
