Using the Sound Retriever
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.

Press , then press S.RETRIEVER to switch the
S.RTV (Sound Retriever) ON or OFF.
Note
• The Sound Retriever is only applicable to 2-channel
sources.
Listening with Acoustic Calibration EQ
You can listen to sources using the Acoustic Calibration
Equalization set in Automatically setting up for surround
sound (MCACC) on page 24 . Refer to these pages for more on
Acoustic Calibration Equalization.

While listening to a source, press , then press
EQ to switch the EQ (Acoustic Calibration EQ) ON or
OFF.
The MCACC indicator on the front panel lights when
Acoustic Calibration EQ is active.
• You can’t use Acoustic Calibration EQ with Stream
Direct mode and it has no effect with headphones.
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.

While listening to a source, press , then 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.
