Acoustic Calibration EQ
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 (MCACC)
on page 8 or
Automatic
MCACC (Expert)
on page 36, you can also adjust these
settings manually to get a frequency balance that suits
your tastes.
1 Select ‘EQ Adjust’ from the Manual MCACC setup
menu.
2 Confirm that the MCACC preset shown in the
display is the one you want to adjust, then select OK.
3 Select the channel(s) you want and adjust to your
liking.
Use the
/
buttons to select the channel.
Use the
/
buttons to select the frequency and
/
to boost or cut the EQ. When you’re finished, go back to
the top of the screen and use the
/
buttons to select
the next 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.

You will return to the Manual MCACC setup menu.
Professional Acoustic Calibration EQ
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 Professional Acoustic Calibration EQ
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
Aco Cal EQ Pro.
(or
ALL
) for the
Auto Mode
setting in
Automatic MCACC (Expert)
on
page 36 to calibrate the room automatically. This should
provide a balanced calibration that suits the
characteristics of your listening room.
