Compression artifacts (such as the MP3 format) are
created by a lossy compression scheme where the audio is
resampled to lower the bit rate and to remove sounds that
are indistinguishable to typical human hearing. The
Compressed Music Enhancer feature of this unit enhances
your listening experience by regenerating the missing
harmonics in a compression artifact. As a result, flattened
complexity due to the loss of high-frequency fidelity as
well as lack of bass due to the loss of low-frequency bass
is compensated, providing improved performance of the
overall sound system.
• When you play back DSD sources or PCM sources whose
sampling frequencies are higher than 48 kHz, this unit samples
them down to 48 kHz or lower and applies the Compressed
Music Enhancer mode.
• The Compressed Music Enhancer mode is not effective with
any of the sound field programs.
Press ENHANCER on the front panel (or set the
operation mode selector to AMP and then press
ENHANCER on the remote control) repeatedly to
select the desired Compressed Music Enhancer
mode.
The following display is shown in the OSD and the
ENHANCER indicator lights up in the front panel display.
Choices: 2ch Enhancer, 7ch Enhancer, Off
• Select “2ch Enhancer” to play back compression
artifacts in 2-channel stereo.
• Select “7ch Enhancer” to play back compression
artifacts in 7-channel stereo.
• Select “Off” to turn off the Compressed Music
Enhancer mode.
When you select “Off”, this unit returns to the previously
selected sound field program.
■ Changing the parameter of the
Compressed Music Enhancer mode
Press PARAMETER and then l / h on the
remote control to select the desired effect level.
The following display is shown in the OSD.
Choices: HIGH, LOW
• Select “HIGH” for a high effect level.
• Select “LOW” for a low effect level.

Press PARAMETER to turn off the Compressed Music
Enhancer mode parameter display.
Set the effect level to “HIGH” or “LOW” according to the
characteristics of a source. The high-frequency signals of
some sources may be emphasized too much. In this case, set
the effect level to “LOW”.
