Introduction
Before you begin 
Thank you for purchasing the Bose 
® 
 3•2•1 home entertainment system, which offers superb 
sound, elegance, and simplicity in an advanced home audio setup. Using Bose proprietary 
signal processing technology, the 3•2•1 system provides improved spaciousness from stereo 
recordings, and bold movie effects from surround-encoded materials. Yet its few parts require 
little labor to set up, so you can enjoy your new system’s performance right away.
Your system includes:
•Integrated AM/FM tuner and DVD/CD player in a small console
•Small, easy-to-place shelf speakers and an attractive floor-standing Acoustimass 
® 
 module
•Easy-to-use infrared remote control
•Console input jacks for connecting other source components (such as a VCR, DSS, CD 
changer, or tape deck) 
Selecting compatible discs 
The DVD/CD player built into the 3•2•1 media center can play the following types of discs 
identified by their corresponding logos:
•Video DVDs
•Audio CDs
•CD-R and CD-R/Ws
•MP3 on CD  
Check for region code compatibility 
For any 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. 
Check the region code number on the carton for the 3•2•1 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 player should display the following mark:  
How text is used in this owner’s guide

Glossary of terms

D  
– The trademarked logo for Dolby Digital, a perceptual coding system for audio, devel-
oped by Dolby Laboratories. Dolby Digital is the most common means of encoding audio for 
DVD-Video.  
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 in the U.S., 4:3 and 16:9.

Introduction 
S-video 
 – A video interface standard that carries separate luminance and chrominance sig-
nals, usually on a four-pin mini-DIN connector. Also called Y/C. The quality of S-video is sig-
nificantly 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. 
Track 
 – Individual selections recorded on an audio tape or disc. 
For your records

mass 
®

System Setup
Selecting locations for your Model 3•2•1 speakers and media center 
Use the following guidelines to choose locations and positions for the speakers and media 
center.  
Note:  
While these guidelines are offered to ensure the best system performance, you may 
find other placement variations that are more convenient and provide the sound you enjoy. 
Keep in mind that the media center connects to both speakers and to the Acoustimass 
® 
 mod-
ule, while the module is the only part of this system that connects to a power outlet. 
Placing the small speakers 
Choosing a good location for the speakers will allow you to experience the audio spacious-
ness and surround effects that your Model 3•2•1 home entertainment system is designed to 
deliver. 
•Be sur
e to face each speaker straight ahead (toward the listening area), so it can cover the 
broadest listening area (Figure 2).

Placement  
Note:  
Angling one or both speakers into or away from the listening area significantly alters 
system performance.

Placement of the small 
speakers near a flat wall or 
in a corner position  
•If you are using a bookshelf or a home entertainment unit, place each speaker at the front 
edge of its shelf 
.  
Note:  
Positioning these speakers farther back in an enclosed space can change the overall 
quality of sound and alter the movie effects. 
CAUTION:  
Choose a stable and level surface for both speakers. Vibration can cause the 
speakers 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 supplied 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.

System Setup 
•Place the speakers on top of the TV or to the left and right of your TV screen (refer to
Figure 3 on page 9) and at roughly equal distance from it. 
Note:  
The speakers are magnetically shielded to prevent interference when they are on or 
near the TV. 
•Maintain at least 3 feet (1 meter) of space between the two speakers.
Place the speakers up to 3 feet (1 meter) from the edges of the TV screen.
Bose 
® 
 recommends a maximum distance of 3 feet from each speaker to the edge of the TV 
screen to prevent the sound from becoming too separated from the picture. You may vary 
this distance, however, based on room conditions and your personal preference.
•Keep both speakers at approximately the same height.
The small speakers are designed to sit only on their bottom surface (Figure 4). In that position 
(with the Bose logo right side up), they can also be mounted on optional Bose brackets, table 
stands, or floor stands. For details and ordering information, refer to Accessories on page 40.

Media center placement 
Place the media center where nothing obstructs opening the disc tray on its front panel.
Be sure it is within reach of the cables connected to the Acoustimass 
® 
 module and the speak-
ers. Make sure it is close enough to additional source components (TV, tape player, VCR) for 
all the cables to reach. 
If additional audio cables are needed for these connections, contact Bose or your dealer. To 
contact Bose, refer to the list of offices included in the product carton.
