The System Setup menu

Using Professional Acoustic Calibration EQ

Select ‘EQ Professional’ then press ENTER.

Select an option and press ENTER.

•

Reverb Measurement

– Use this to measure the

reverb characteristics of your room (for graphical
output using a PC, see

Connecting a PC for Advanced

MCACC output

on page 59 to connect an RS-232C

cable before selecting this option).

•

Reverb View

– You can check the reverb

measurements made for specified frequency ranges
in each channel.

•

Reverb Output PC

– See

Connecting a PC for

Advanced MCACC output

on page 59 for more on this.

•

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

(MCACC)

on page 7 or

Automatic MCACC (Expert)

page 33 and is not necessary if you’re satisfied with
these settings.

If you selected ‘Reverb Measurement’, select EQ

ON or OFF and then OK.

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

Reverb View

and

Reverb Output PC

•

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 76

for troubleshooting information.

If you selected ‘Reverb View’, you can check the

reverb characteristics for each channel. Press
RETURN when you’re done.

This appears according to the setting you chose in

Reverb Measurement

(step 3 above). Use the

buttons to select the channel and the frequency you want
to check. Use the

buttons to go back and forth

between the two. Note that the markers on the vertical
axis indicate decibels in 2dB steps.

If you selected ‘Advanced EQ Setup’, input the

time setting you want to use for calibration, then
select ‘Go’. Select ‘Start’ from the next screen.

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

20–40ms

setting.

Use the

buttons to select the channel, frequency,

and time setting. Use the

buttons to switch

between them.

You can switch between your connected speakers
(excluding the subwoofer), and display the
measurements for the following frequencies: 63Hz, 125
Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz and 16kHz.

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

. It will take about 1–4

minutes for the calibration to finish.

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

System Setup menu and

press

MCACC

to select it before pressing
