Pioneer VSX-LX52 manual 1c5a.Reverb Measurement, 1c5b.Reverb View, 1c5c.Adv.EQ Setup

The Advanced MCACC menu 10

•Advanced EQ Setup – Use this to select the time

period that will be used for frequency adjustment and calibration, based on the reverb measurement of your listening area. Note that customizing system calibration using this setup will alter the settings you made in Automatically setting up for surround sound (Auto MCACC) on page 39 or Automatic MCACC (Expert) on page 72 and is not necessary if you’re satisfied with these settings.

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

The following options determine how the reverb

characteristics of your listening area are displayed in Reverb View and Output PC (see Connecting a PC for Advanced MCACC output on page 34):

•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).1 Note that the EQ

response may not appear entirely flat due to adjustments necessary for your listening area.2

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 96 for troubleshooting information.

4If 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 Full Auto MCACC or Reverb Measurement measurements are conducted.3

Use / to select the channel, frequency and calibration setting you want to check. Use / 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.4 Note that the markers on the vertical axis indicate decibels in 2 dB steps.

5If ‘Advanced EQ Setup’ is selected, select the MCACC memory to be stored, then enter the desired time setting for calibration, and then select START. 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 / to select the setting. Use / to switch between them.

Select the setting from the following time periods (in milliseconds): 0-20ms, 10-30ms, 20-40ms, 30-50ms, 40- 60ms, 50-70msand 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.

Note

1• The calibration corresponding to the currently selected MCACC preset will be used when EQ ON is selected. To use another MCACC preset, exit the HOME MENU and press MCACC to select it before pressing HOME MENU.

• The predicted reverb characteristics after calibration can be acquired with the Full Auto MCACC function (Automatically setting up for surround sound (Auto MCACC) on page 39), but here the actually measured reverb characteristics after calibration can be acquired.

2After 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.

3The After display when measurements have been made using the Full Auto MCACC or Auto MCACC (ALL) function shows the graph for the inferred reverb characteristics after EQ Type : SYMMETRY calibration.

4The reverb characteristics graph is overwritten each time the reverberations are measured. No Data is displayed if there is no reverb characteristic data, for example before measurements have been taken.
