    Checking for region code compatibility
    For a DVD player and DVD disc to be compatible, their region code numbers must match. 
    These numbers are allocated according to where the player and disc are sold. The 3•2•1 
    Series II DVD home entertainment systems have a region code which must also match the 
    DVD discs.
    Check the region code number on the carton of the 3•2•1 Series II DVD home entertainment 
    system or on the bottom of the media center that comes in the carton. Then be sure to 
    choose only DVD discs that show the same region number on the disc label or front cover. 
    For example, a Region 1 DVD disc should display the following mark: 
    Glossary of terms
    Aspect Ratio – The shape of the rectangular picture in a TV set. It is the width of the picture 
    relative to the height. Our standard TV picture, in terminology used by that industry, is 4 units 
    wide by 3 units high, or 4:3 (read as 4 by 3) in aspect ratio. There are currently two standard 
    TV aspect ratios, 4:3 and 16:9.
    Chapter – In DVD-Video, a division of a title. Technically called a part of title (PTT).
    Component Video – A video signal split into three parts: luminance and two color signals 
    (marked as YPbPr). It provides the highest resolution video, but cannot be processed by all 
    television sets. 
    Composite Video – A single video signal that contains luminance, color, and synchronization 
    information. NTSC and PAL are examples of composite video systems.
    Dolby Laboratories
    – Developer of a perceptual coding system for audio.
    Dolby Digital – a type of multi-channel surround sound format used on discs. 
     – the logo representing Dolby® Digital.
    DTS – a type of multi-channel surround sound format used on discs.
     – the logo representing DTS.
    DVD – An acronym that is most commonly known to mean Digital Video Disc or Digital 
    Versatile Disc. The audio/video/data storage system based on 12- and 8-cm optical discs.
    DVD Video – A standard for storing and reproducing audio and video on DVD-ROM discs, 
    based on MPEG video, Dolby Digital and MPEG audio, and other proprietary data formats.
    IR – An acronym for infrared. Pertains to the type of remote that sends/receives commands 
    on an infrared light beam.
    Letterbox – The projected aspect ratio of feature films is often 16:9 rather than the 4:3 aspect 
    ratio of most TVs. Therefore, it is becoming common practice to transfer films to video with 
    black borders at the top and bottom of the picture. The film picture becomes a “letterbox” 
    within the video.

    MPEG – a type of data compression used for audio or video storage on disc.
    MP3 – MPEG-1 Layer III audio. This is a compressed audio format that allows you to record 
    many hours of music on a single CD.
    NTSC – An acronym for National Television System Committee. The organization that devel-
    oped both the American Black & White and Color television systems.
    PA L – An acronym for Phase Alternate Line. A television format used extensively in Western 
    Europe.
    S-video – A video interface standard that carries separate luminance and chrominance 
    signals, usually on a four-pin mini-DIN connector. Also called Y/C. The quality of S-video is 
    significantly better than composite video since it does not require a comb filter to separate 
    the signals. Most high-end televisions have S-video inputs.

    Selecting locations for your 3•2•1 Series II system components
    Use the following guidelines and Figure 2 to choose locations and positions for the compo-
    nents of your 3•2•1 home entertainment system.
    Note:
    While these guidelines are offered to help provide great system performance, you may find 
    other placement choices that are more convenient and provide the sound you enjoy.
    Placing the media center
    CAUTION: Do not block any ventilation openings. For reliable operation of the product and to 
    protect it from overheating, put the product in a position and location that will not interfere with its 
    proper ventilation. For example, do not place the product on a bed, sofa, or similar surface that 
    may block the ventilation openings. Do not put it in a built-in system, such as a bookcase or cab-
    inet that may keep air from flowing through its ventilation openings.
    • Place the media center where nothing obstructs opening the disc tray on its front panel.
    • Make sure the media center will be placed close enough to the Acoustimass
    ® module and 
    the speakers so that all the cables will reach. 
    • Make sure the media center will be placed close enough to additional source devices (TV, 
    VCR or cable box) so that all the cables will reach.
    Note:
    Make sure that the front of the media center is unobstructed so that it may receive 
    IR (infrared) commands from the remote control.

    Placing the speakers
    Choosing a good location for the speakers will allow you to experience the audio surround 
    effects that your 3•2•1 home entertainment system is designed to deliver.
    • Place the two speakers either on top of the TV or at equal distance from the left and right of 
    the TV screen (Figure 2). Keep both speakers at approximately the same height.
    • Place each speaker within 3 feet (1 meter) of the edge of the TV screen. Placing the 
    speakers more than 3 feet away from the TV can cause the sound to become separated 
    from the picture.
    • If you are using a bookshelf or a home entertainment unit, place each speaker at the 
    front edge of its shelfPositioning the speakers too far back in an enclosed space can 
    change the overall quality of sound and alter the movie sound effects.
    • Place the speakers at least 3 feet (1 meter) apart from each other to optimize the 
    surround sound experience.
    CAUTION: 
    Choose a stable and level surface for both speakers. Vibration can cause the speak-
    ers to move, particularly on smooth surfaces like marble, glass, or highly polished wood. If you 
    are placing the speakers on a flat surface, be sure to attach the smaller of the two sets of sup-
    plied rubber feet to the bottom surface. You may obtain additional rubber feet (part number 
    178321) from Bose
    ® Customer Service. To contact Bose, refer to the list of offices included in the 
    product carton.
    Note:
    The speakers can be mounted on Bose brackets, table stands, or floor stands. For order-
    ing information, refer to “Accessories” on page 54. Additional or longer cables may also be 
    ordered.
    Figure 3
    Recommended speaker 
    placement
    • Place the speakers only on their bottom surfaces, with the Bose logo right-side up.
    • Aim the speakers straight ahead toward the listening area. Do not place the speakers at an 
    angle. Angling one or both speakers into or away from the listening area signifi-
    cantly alters system performance.
