Onkyo TX-SR577 Using the Music Optimizer, Specifying the Digital Signal Format, PCM, DTS, or Auto

Basic Operations—Continued

Using the Music Optimizer

The Music Optimizer function enhances the sound quality of compressed music files. Use it with music files that use “lossy” compression, such as MP3.

To turn the Music Optimizer “On” or “Off”, use the AV receiver’s [MUSIC OPTIMIZER] button (North American/Taiwan models only).

The setting is stored individually for each input selector.

Off: Music Optimizer off (default).

On: Music Optimizer on.

Tip:

This procedure can also be performed on the remote controller by using [AUDIO] button (see page 79).

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.

Specifying the Digital Signal Format

The following table shows the display indicator for each digital signal format.

Format	Display
Dolby Digital
DTS
PCM		PCM

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.
