Basic Operations—Continued
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 Opti-
mizer is disabled when the Direct 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.
Using the Music Optimizer
To turn the Music Optimizer “On”
or “Off”, use the AV receiver’s
[MUSIC OPTIMIZER] button.
Tip:
This procedure can also be performed
on the remote controller by using
[AUDIO] button (see page 59).
Off: Music Optimizer off (default).
On: Music Optimizer on.
