Playing back discs

This system has been designed to play back the following discs—

CD, finalized CD-R/CD-RW (recorded in audio CD format) and

CD-R/CD-RW (in MP3 format).

• This system is not compatible with the other discs such as DVD,

DVD-R, and DVD-RW.

Notes on MP3:

• The system can only recognize files (tracks) with “MP3” or

“mp3” as the extensions, which can be in any combination of

upper and lower case.

• It is recommended that you record your material at a 44.1 kHz

sampling rate, using the 128 kbps data transfer rate.

• You can play back the discs containing the tracks in music CD

format or MP3 files in ISO 9660 format.

• Some MP3 tracks or discs may not be played back because of

their characteristics or recording conditions.

• MP3 discs require a longer readout time than normal discs.

• This system recognizes up to 999 tracks on a disc (or less

depending on the recording condition of a disc).

system is turned off,

Turns on the system and selects AUX as the source.

NOTES:

• When the sound signal from the auxiliary equipment is too weak,

QP Link may not function correctly. In this case, turn up the

volume of the auxiliary equipment so that the system can detect

the sound signal properly.

• If you change the source from AUX with QP Link turned on, QP

Link will be deactivated temporarily. In this case, the following

reactivate QP Link:

– When the auxiliary equipment is unplugged from the AUX

jack, then plugged in again.

– When the sound signal from AUX jack stops or becomes very
