The Music Optimizer function enhances the sound 
quality of compressed music files. Use it with music files 
that use “lossy” compression, such as MP3.
Note:
The Music Optimizer function only works with PCM 
digital audio input signals with a sampling rate below 
48 kHz and analog audio input signals. The Music 
Optimizer is disabled when the Direct or Pure Audio 
listening mode is selected.
The following table shows the display indicator for each 
digital signal format.
Normally, the AV receiver detects the format of digital 
input signals automatically. However, if you experience 
either of the following issues when playing PCM or DTS 
sources, you can specify the signal format manually.
• If the beginnings of tracks from a PCM source are cut 
off, try the PCM setting.
• If noise is produced when fast forwarding or 
rewinding a DTS CD, try the DTS setting.
• The setting is stored individually for each input 
selector.
Using the Music Optimizer
(North American models) To turn 
the Music Optimizer “On” or 
“Off”, use the AV receiver’s 
[MUSIC OPTIMIZER] button .
The setting is stored individually for 
each input selector.
Tip:
This procedure can also be performed 
on the remote controller by using 
[AUDIO] button (see page 74).

signals will be heard. If the input 
signal is not PCM, the PCM 
indicator will flash and there will be 
no sound.
DTS: 
Only DTS format input signals will 
be heard. If the input signal is not 
DTS, the DTS indicator will flash 
and there will be no sound.
Auto (default): 
The format is detected 
automatically. If no digital input 
signal is present, the corresponding 
analog input is used instead.
