Calibration EQ
• Default setting: ON
You can listen to sources using the Acoustic
Calibration Equalization set in Automatically
setting up for surround sound (MCACC) on
page 45. Refer to these pages for more on
Acoustic Calibration Equalization.
• While listening to a source, press
, then press EQ to switch the
Acoustic Calibration EQ on or off.

Better sound using Phase Control
This system’s Phase Control feature uses
phase correction measures to make sure your
sound source arrives at the listening position in
phase, preventing unwanted distortion and/or
coloring of the sound (see illustration below).
During multichannel playback, LFE (Low-
Frequency Effects) signals as well as low-
frequency signals in each channel are
assigned to the subwoofer or other the
subwoofer and the most appropriate speaker.
At least in theory, however, this type of
processing involves a group delay that varies
with frequency, resulting in phase distortion
where the low-frequency sound is delayed or
muffled by the conflict with other channels.
With the Phase Control mode switched on, this
system can reproduce powerful bass sound
without deteriorating the quality of the original
sound (see illustration below).
Phase Control technology provides coherent
sound reproduction through the use of phase
matching
2 for an optimal sound image at your
listening position. The default setting is on and
we recommend leaving Phase Control
switched on for all sound sources.
• Press , then press PHASE to
switch on phase correction.
Note
1 You can’t use Acoustic Calibration EQ with Stream Direct mode.

2 • Phase matching is a very important factor in achieving proper sound reproduction. If two waveforms are ‘in phase’,
they crest and trough together, resulting in increased amplitude, clarity and presence of the sound signal. If a crest
of a wave meets a trough (as shown in the upper section of the diagram above) then the sound will be ‘out of phase’
and an unreliable sound image will be produced.
• If your subwoofer has a phase control switch, set it to the plus (+) sign (or 0°). However, the effect you can actually
feel when
PHASE CONTROL is set to ON on this system depends on the type of your subwoofer. Set your subwoofer
to maximize the effect. It is also recommended you try changing the orientation or the place of your subwoofer.
• Set the built-in lowpass filter switch of your subwoofer to OFF. If this cannot be done on your subwoofer, set the
cutoff frequency to a higher value.
• If the speaker distance is not properly set, you may not have a maximized
PHASE CONTROL effect.
• When the PURE DIRECT mode is selected, the PHASE CONTROL mode cannot be set to ON.
