INTRODUCTION
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.
INTRODUCTION
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 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.
– Developer of a perceptual coding system for audio.
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 developed both the American Black & White and Color television systems.
PAL – 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.
Title – numbered elements of the DVD contents, which may include more than the movie
alone.
Tra ck – Individual selections recorded on an audio tape or disc.

IMPORTANT
If you connected your TV and VCR this way, you
will need to turn on your VCR and select the
AUX source on the 3•2•1 remote to hear sound
from TV programs.
• Some combination TV/VCR units may not work with 3•2•1 Series II home entertainment
systems. Please refer to your TV/VCR owner’s manual for information.
• A stereo VCR is required for optimal sound performance. If your VCR has only one audio
output and is not labeled Stereo or Hi-fi, you have a mono VCR. You will need a
Y-adapter cable (available at electronics stores) to connect audio to the media center. For
this setup, you will need to select “Mono decoding” (see “TV, CBL•SAT, and AUX settings
menu” on page 44) so your 3•2•1 system will simulate surround sound effects from a mono
source. Otherwise, you will hear mono sound from both speakers.
Making S-video connections (higher quality video)
An S-video input jack, provided on many TVs, delivers a higher quality TV picture than the
composite video output connection shown in Figure 11. For this connection you will need an
S-video cable which can be purchased from your Bose dealer or a local electronics retailer.
• Insert one end of the S-video cable into the S-Video OUT jack on the media
center (Figure 14).
• Insert the other end of the S-video cable into the S-VIDEO IN jack on your TV.

IMPORTANT
If you use S-video to
connect your TV to the
media center, you
must also use S-video
to connect all other
devices (such as a
cable box and VCR) to
the media center.
Making component video connections (highest quality video)
Note: Component video connections are required in order to use the progressive scan feature of
your 3•2•1 system. Your TV must also support this feature. To turn on the progressive scan feature, see “Video options” on page 48.
For the highest quality video from DVDs, you may want to use a component video connection
between the media center and the TV. To do so, your TV must provide component video jacks
(typically labelled Y, Pb, and Pr). Refer to your TV owner’s guide for more information.
To make component video connections you will need three video grade cables that are long
enough to reach from the rear of the media center to your TV (Figure 15). If the cables are not
supplied with your TV, you can purchase them separately.
1. On the media center rear panel, plug one video cable into the Component Y, Pb, and Pr
video output jacks (Figure 15).
2. Plug the other end of each video cable into the corresponding (color or letter code) com-
ponent video jack on the back of your TV.

IMPORTANT FOR COMPONENT VIDEO USERS
Input signals received by the C (Composite) or S-Video IN jacks are not passed through to
the Component video OUT jacks. If you connect an external video device to the C or S-Video IN jack, you must also connect the C or S-Video OUT jack on the media center to
the respective video input jack on your TV. To view the external video input on your TV, you
will need to select the TV video input used for that device. To view the onscreen menus of
the 3•2•1 system, you will need to switch back to the TV’s component video input.
Note:
For more information, or to purchase the video cables, contact your local electronics store
or authorized Bose dealer.
Some audio devices may feature a digital audio output for optimum sound performance. Use
an optical digital cable or a coaxial digital cable, as appropriate, to connect this output to the
digital input on the media center. You can purchase the required cables at a local electronics
store.
On the media center rear panel, an optical digital cable connects to the OPTICAL jack. A
coaxial cable connects to the audio input jacks labeled D.
Note:
Before you can benefit from the optical connection, you will need to assign the optical
connector to the audio source in the system settings menu. See “Media center options” on
page 49.

Connecting your cable/satellite box, TV, and VCR to the media center
The 3•2•1 home entertainment system provides flexibility for you to add up to three external
audio devices, including your TV, directly to the media center.
Figure 17 shows you an advanced setup using a TV, VCR and cable/satellite box. In this
setup, please notice the following:
• S-video connections are used to deliver the cable/satellite signal to the media center.
Therefore, the media center output video is sent to the TV also through an S-video
connection.
• Analog and digital coax audio connections are shown for the cable/satellite box. As an
option, you may use an optical digital connection. However, before you can benefit from the
optical connection, you will need to assign the optical connector to the cable/satellite box
audio source in the system settings menu. See “Media center options” on page 49.
• When connecting an audio device to the media center jacks, remember to match the red
jack to the right channel (R) and the white (or black) jack to the left channel (L).
• For further details on making the video connections between your VCR and TV, refer to the
manuals for these video devices.
