Using Acoustic Calibration EQ Professional

1 Select ‘

EQ Professional

’, then press

ENTER

2 Select an option and press

ENTER

• Reverb Measurement – Use this to measure the

reverb characteristics before and after calibration.

• Reverb View – You can check the reverb

measurements made for specified frequency ranges

in each channel.

• 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 conducting optimum sound

tuning (Auto MCACC) on page 37 or Automatic

MCACC (Expert) on page 73 and is not necessary if

you’re satisfied with these settings.

3 If you selected ‘

Reverb Measurement

’, select

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 necessary for your listening area.

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 93

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 Full

Auto MCACC or Reverb Measurement measurements

are conducted.

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.

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, 50-70ms 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 cali

bration to finish.

After the Acoustic Calibration Equalization is set, you are

given the option to check the settings on-screen.

Note

1If the Reverb View procedure is performed after the Automatically conducting optimum sound tuning (Auto MCACC) on page 37 or Reverb

Measurement operation, depending on the standing wave control setting, differences may appear on the reverb graph. With the Auto MCACC

function, the reverberations are measured with the standing waves controlled, so the reverb characteristics graph shows the characteristics

with the effect of the standing waves eliminated. By contrast, the Reverb Measurement function measures the reverberations without

controlling the standing waves, so the graph indicates the reverb charac

teristics including the effect of the standing waves. If you wish to

check the reverb characteristics of the room itself (with the standing waves as such), we recommend using the Reverb Measurement

function.

2 • 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.

• The predicted reverb characteristics after calibration can be acquired with the Full Auto MCACC function (Automatically conducting

optimum sound tuning (Auto MCACC) on page 37), but here the actually measured r everb characteristics after calibration can be acquired.

3After 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 char acteristics after EQ calibration, measure with EQ ON.

4The After display when measurements have been made using the Full Auto MCACC or Auto MCACC (ALL or KEEP SP system) function

shows the graph for the inferred reverb characteristics after EQ Type : SYMMETRY calibration.

5To specify the place where the MCACC memory is to be stored, press MCACC to select the MCACC memory you want to store.
