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 13). 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 13). 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 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.
1 Connect the receiver to your PC with an RS-232C cable.
If the “Full Auto MCACC” operation has never been performed, conduct the “Full Auto MCACC”
operation here.
(See page 41 of the receiver’s Operating Instructions.)
2 Select the “EQ Professional” option for “Manual MCACC”, and perform with
“Reverb Measurement” set to “EQ ON”.
(See page 84 of 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.
3 Receive and save the data by selecting “Output PC” from “MCACC Data Check”.
You can display the graph of the reverberation characteristics actually measured after EQ calibration by
displaying the Reverb graph and selecting “After”.
