Better sound using Phase
Control
This receiver’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.
Phase Control technology provides coherent
sound reproduction through the use of phase
matching for an optimal sound image. The
default setting is on and we recommend leav-
ing Phase Control switched on for all sound
sources.
1
Press
to the receiver operation
mode.
2
Press PHASE CTRL (PHASE CONTROL) to
switch on phase correction.
The
PHASE CONTROL
indicator on the front
panel lights.
Note
!
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,
then the sound will be ‘out of phase’ and an
unreliable sound image will be produced.
!
The
PHASE CONTROL
feature is available
even when the headphones are plugged in.
!
If your subwoofer has a phase control switch,
set it to the plus (+) sign (or 0º). However,
the effect you can actually feel when
PHASE CONTROL
is set to
ON
on this receiver
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.
!
The
PHASE CONTROL
mode cannot be set to
ON
in the following cases:
—
When the
PURE DIRECT
mode is switched
on.
—
When the
HDMI
audio output parameter is
set to
THROUGH
in Setting the
Setting the
Audio options
