Disc compatibility guide

The following discs are compatible with 3∙2∙1 systems:

Video compatibility





Audio compatibility




MP3 on CD

DVD-R DL (Dual Layer), DVD+R, DVD+RW, DVD+R DL, SVCD: These formats are not officially supported. However, they may play on the system, depending on disc brand, recording software used, and quality of the CD/DVD burner. However, if one of these disc types fails to play, it is because its format is not supported.

DVD-Audio: Some DVD-Audio discs contain Dolby Digital tracks that all DVD players (including Bose® DVD-based systems) can play. Bose DVD-based systems only play the Dolby Digital audio track. Some DVD-Audio discs have the Dolby Digital tracks on the opposite side of the disc; others have the option in the disc setup menu. A specifically dedicated DVD-Audio player must be used to play the DVD-Audio format. An external DVD-Audio player may be connected to a Bose system, but only its stereo output can be used. Bose systems do not have multichannel input jacks to accept the multichannel output from a DVD-Audio player.

Super Audio CD (SACD): The system plays only standard CD audio tracks on a hybrid SACD disc. Hybrid discs contain both the SACD and standard CD formats. If the SACD disc is not a hybrid, you need a dedicated SACD player. Connect this player to the Bose system using the stereo inputs or AUX IN. Since the Bose system does not have multi-channel input jacks, the sound from the SACD player will be delivered in stereo.

DualDisc: The CD side of a DualDisc does not conform to the Phillips and Sony Red Book standards and DualDiscs are not allowed to display the CD logo. The CD side of the DualDisc may not play consistently or at all. Most DualDiscs contain one of two warnings:

"This disc is intended to play on standard DVD and CD players. It may not play on certain car, slot-load players and mega-disc changers"

"The audio side of this disc does not conform to CD specifications and therefore not all DVD and CD players will play the audio side of this disc"

The DVD side of a DualDisc conforms to DVD Forum specifications. DualDiscs are allowed to display the DVD logo.

MP3 compatibility requirements

Bose systems do not play MP3s recorded at rates lower than 64kbps. Audio quality is very low below that point. Bose systems may have problems reading MP3s recorded at a variable bit rate. The track may play, but if the bit rate falls below 64kbps the decoder does not have enough digital information to play audio. MP3s created with a volume-leveling feature are not compatible with Bose systems. (Current versions of MusicMatch, a CD-ripping software program, have a volume-leveling feature, which, when enabled, creates a consistent volume level for all tracks). MP3 filenames should contain only one period "." and the system looks for the .MP3 extension to identify the file type. For example, the system would be unable to interpret a filename with two periods such as "HILL ST. BLUES.MP3" because it would be seen as a ". BLUES" file. Information, such as graphics and song lyrics, may not be recognized by your system (the latest CD-ripping programs can help you differentiate ID3 Version 1 and 2 tags and may also allow you to convert Version 2 to Version 1). Do not use software such as Direct CD which uses Microsoft Internet Explorer to drag and drop files from a hard drive to a CD. This CD burning method generates CDs that are incompatible with your system. Use a software program that displays an actual user interface.

Recommended MP3 formats

Bose systems are compatible with single and multi-session discs, including single-session mixed-mode discs. CDs must be finalized to play on Lifestyle® and 3∙2∙1 systems. Wave® music systems and TriPort® CD systems will play CDs if they are not finalized. These formats are recommended:

Linked and unlinked sessions

International (non-English) TTAG and ID3 Tag information

Compatible with UDF formats: Fixed or Variable packet, Version 1.5 or 2, UDF with ISO bridge, Easy CD Format (that uses a different method)

Mode 1 and Mode 2 (Form 1 and Form 2)

Disc format ISO9660 with or without extended

Macintosh burned disc via ISO image

MPEG 2.5 Layer 3

MP3 tips

You should burn a CD in one session only. A multi-session disc may play, but it is not always compatible, and may result in intermittent audio. Rip CDs at a minimum of 128 kbps, with a 44.1 khz sampling rate.
