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
1
for an optimal sound image. The
default setting is on and we recommend
leaving Phase Control switched on for all
sound sources.
• Press , then press PHASE CTRL
(PHASE CONTROL) to switch on phase
correction.
The
PHASE CONTROL indicator on the front
panel lights.
Note
1 • 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 0°). 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 Audio options on page 67.
