• 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).

Acoustic Calibration EQ Adjust
• Default setting: ON 1 / 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 conducting optimum sound
tuning (Auto MCACC) on page 39 or Automatic
MCACC (Expert) on page 87, 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 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.
3 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.
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
(when Type A or Type B shown on the
diagrams on the following applies), select
EQ
Pro. & S-Wave (or ALL) for the Auto MCACC
setting in Automatic MCACC (Expert) on
page 87 to calibrate the room automatically.
Note
1 When EQ Adjust is selected for an MCACC preset memory where EQ is set to OFF in the AUDIO PARAMETER, EQ
ON is automatically selected.
