•

Freq / Q / ATT – These are the filter parameters where
Freq represents the frequency you will be targeting
and

Q is the bandwidth (the higher the Q, the

narrower the bandwidth, or range) of the attenuation
(

ATT, the amount of reduction to the targeted

frequency).

When you’re finished, press RETURN.

You will return to the

Manual MCACC setup menu.

Acoustic Calibration EQ Adjust

• Default setting:

0.0dB (all channels/bands)

Acoustic Calibration Equalization is a kind of room
equalizer for your speakers (excluding the subwoofer). It
works by measuring the acoustic characteristics of your
room and neutralizing the ambient characteristics that
can color the original source material (providing a ‘flat’
equalization setting). If you’re not satisfied with the
adjustment provided in

Automatically setting up for

surround sound (Auto MCACC & Full Band Phase Control)
on page 45 or

Automatic MCACC (Expert) on page 107,

you can also adjust these settings manually to get a

frequency balance that suits your tastes.

Select ‘EQ Adjust’ from the Manual MCACC setup

menu.

Select the channel(s) you want and adjust to your

liking.

Use

/ to select the channel.

Use

/ to select the frequency and / to boost or

cut the EQ. When you’re finished, go back to the top of
the screen and press

 to return to Ch, then use / to

select the channel.

• The

OVER! indicator shows in the display if the

frequency adjustment is too drastic and might
distort. If this happens, bring the level down until
OVER! disappears from the display.

Tip

• Changing the frequency curve of one channel too

drastically will affect the overall balance. If the speaker
balance seems uneven, you can raise or lower channel
levels using test tones with the

TRIM feature. Use

/

 to select TRIM, then use / to raise or lower the
channel level for the current speaker.

When you’re finished, press RETURN.

You will return to the

Manual MCACC setup menu.

Acoustic Calibration EQ Professional

This setup minimizes the unwanted effects of room
reverberation by allowing you to calibrate your system
based on the direct sound coming from the speakers. It
can also provide you with a graphical output of the
frequency response of your room.

How to use Acoustic Calibration EQ Professional

If you find that lower frequencies seem overly reverberant
in your listening room (i.e. it sounds ‘boomy’), or that
different channels seem to exhibit different reverb
characteristics, select

EQ Pro & S-Wave (or ALL) for the

Auto MCACC setting in Automatic MCACC (Expert) on
page 107 to calibrate the room automatically. This should
provide a balanced calibration that suits the
characteristics of your listening room.

If you still aren’t satisfied with the results, the manual
Advanced EQ Setup (below) provides a more
customized calibration of your system using the direct
sound of the speakers. This is done with the help of a
graphical output that can be displayed on-screen, or
using a computer (with software available from Pioneer
— see

Output PC on page 117).

How to interpret the graphical output

The graph shows decibels on the vertical axis and time (in
milliseconds) on the horizontal axis. A straight line
indicates a flat-response room (no reverb), whereas a
sloping line indicates the presence of reverberation when
outputting test tones. The sloping line will eventually
flatten out when the reverberant sound stabilizes (this
usually takes about 100 ms or so).

Note

1 You can switch on or off the Acoustic Calibration EQ feature in the

AUDIO PARAMETER menu. See Setting the Audio options on page 85 for

SC-LX72
