The Advanced MCACC menu

3 If you selected ‘Reverb Measurement’, select EQ ON or EQ OFF, and then START.

The following options determine how the reverb characteristics of your listening area are displayed in

Reverb View:

! 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 neces-

sary 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 101 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 displayed when the 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

selecting 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 measurement 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 settings on-screen.

Checking MCACC Data

87 for more on this.

! Standing Wave – Used to check the standing wave control filter settings. See Standing Wave on page 87

for more on this.

See Acoustic Cal EQ on page 87 for more on this.

4 Press RETURN to go back to the MCACC Data Check menu, repeating steps 2 and 3 to check

other settings.

5 When you’re finished, press RETURN.
