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 at your listening position. The default
setting is on and we recommend leaving Phase Control
switched on for all sound sources.

Press PHASE to switch the P.CTL (Phase Control) ON or
OFF.
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.
• 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 headphones are connected.
Setting the Audio options
There are a number of additional sound settings you can
make using the AUDIO PARAMETER menu. The defaults, if
not stated, are listed in bold.
Important
• Note that if a setting doesn’t appear in the AUDIO
PARAMETER
menu, it is unavailable due to the current
source, settings and status of the receiver.

S.DELAY (Sound Delay)
Some monitors have a slight delay when
showing video, so the soundtrack will be
slightly out of sync with the picture. By adding
a bit of delay, you can adjust the sound to
match the presentation of the video.
0 to 500 ms (1

MIDNIGHT /LOUDNESS a
The MIDNIGHT allows you to hear effective
surround sound of movies at low volumes.
The LOUDNESS is used to get good bass and
treble from music sources at low volumes.

S.RTV (Sound Retriever) b
When audio data is removed during the
compression process, sound quality often
suffers from an uneven sound image. The
Sound Retriever feature employs new DSP
technology that helps bring CD quality sound
back to compressed 2-channel audio by
restoring sound pressure and smoothing
jagged artifacts left over after compression.

F.PCM (Fixed PCM)
This is useful if you find there is a slight delay
before OFF recognizes the PCM signal on a
CD, for instance.
When ON is selected, noise may be output
during playback of non-PCM sources. Please
select another input signal if this is a problem.
