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.

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 (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
receiver can reproduce powerful bass sound
without deteriorating the quality of the original
sound (see illustration below).
