Dolby Digital Decoder
DigitalTheater 7000 uses a state-of-the-art
Dolby Digital decoder. It accepts a digital data
stream from either of two digital inputs or con-
verts either of two stereo analog inputs to digi-
tal format. The digital data can be either
encoded Dolby Digital or linear PCM data. The
decoder automatically detects the difference.
Center Channel Unit
This integrated unit goes on top of the TV
and houses the center speaker, an alpha-
numeric display, and the infra-red remote con-
trol receiver. The center speaker is a two way
design with a 31⁄2” (89mm) copolymer bass
unit and 3⁄4” (19mm) dome tweeter.
DigitalTheater 7000 utilizes MagnaGuard®
magnetic shielding on the subwoofer and
front speakers to prevent television picture
interference or accidental disk erasure. The
pre-programmed universal remote control
operates the DigitalTheater 7000, and
hundreds of different models of TVs, VCRs
and cable boxes.
DigitalTheater 7000 Subwoofer
with BassTracTM
The DigitalTheater 7000 Subwoofer provides
dramatic bass impact. It uses our long-excursion
8-inch (200mm) bass driver in a bass reflex
enclosure. The result is a subwoofer that deliv-
ers deep, clean bass from a compact enclosure.
Because of it’s high-powered amplifier and
computer-optimized tuning, it is capable of
impressive deep bass and high output from it’s
remarkably compact enclosure. In addition, this
subwoofer features BassTracTM, a proprietary
new Boston-designed circuit that tracks the
input signal to the subwoofer and prevents its
amplifier from being driven into audible distor-
tion. The benefit: The bass stays clean and
strong at any listening level.
DigitalTheater 7000 Satellites
The DigitalTheater 7000 system provides
four satellite speakers for the left and right
front and left and right surround channels.
The left and right front speakers match the
center design with a 31⁄2” (89mm) copolymer
bass unit and 3⁄4” (19mm) dome tweeter.
These speakers can be mounted on the
wall, using the supplied wall-mounting
brackets. Alternatively they can be placed
on a bookshelf or table-top using the rubber
feet provided.

Description
The Boston DigitalTheater 7000 is an integrated home theater sound system. It accepts signals
from digital or analog sources, decodes them to produce surround sound for up to six channels
and provides the amplifiers and speakers for those six channels. The power section uses separate
actively-equalized amplifiers for each of the speakers, including the subwoofer. All that is needed
is a DVD player, digital DSS satellite TV feed, or Hi-Fi VCR, and a monitor or TV for a complete
home theater system. The DigitalTheater 7000 delivers wide-range, high-fidelity sound from a
package that is easy to install and a pleasure to use.
DT7000 Manual 11/99 rev2 11/24/99 12:19 PM Page 8

Center Channel
Place the DigitalTheater 7000 center channel
on top of the video monitor or TV set. The
front of the speaker should be flush with the
front of the television.
Subwoofer
The level of bass output from the subwoofer
will vary at different positions in the room.
Corner placement provides the most bass
output, while placement near only one wall
provides somewhat less bass. Since low bass
sounds are omnidirectional—the ear can’t tell
from which direction they’re coming—the
subwoofer can be located out of sight in the
corner of the room, yet all the sound, includ-
ing the bass, appears to come from the
DigitalTheater 7000’s front speakers.
Front Satellite Speakers
The best location for the front speakers is
to either side of the video monitor or TV.
The speakers can be wall-mounted, or placed
on a bookshelf, with equally good results.
Rear Satellite Speakers:
The best location for the rear speakers is
to the side and slightly behind the listeners.
The speakers can be wall-mounted facing
out, as shown. It may be easier to run wire
to the speakers if they are mounted near
the floor, facing up towards the ceiling. This
position will produce excellent surround
results. Mounting brackets for both options
are included.

Using the Wall-Mount Bracket
The front left and right satellites may be wall-mounted using the included keyhole bracket. An
optional pedestal shelf stand/wall-mount bracket (Model MRB) is available that provides greater
positioning flexibility. For more information, contact your dealer or Boston Acoustics directly.
Install a #8 or #10 mounting screw
on the wall (not supplied - consult a
knowledgable installer regarding the
proper hardware to use on your wall).
Attach the bracket to the back
of the speaker with the other
1⁄4-20” machine screw and acorn
nut as shown.
If you are running wires behind the
wall, make a 3⁄8” (9.5mm) wire hole,
13⁄4” (44mm) below the mounting
screw for the wire.
Insert one of the 1⁄4-20” machine screws
into the threaded insert on the back of the
satellite as shown.

How to Wire Your Speakers
You need to wire your speakers correctly to obtain the best sound quality and the proper image.
Wiring should just take a few minutes, but it’s important to do it carefully, since incorrect wiring
(such as reversed connections) can result in a poor soundstage or poor bass.
The DigitalTheater 7000 includes all the
necessary speaker wire required for an aver-
age sized room installation. All the wires are
18 gauge and have pre-stripped bare wire
leads that connect to the speaker. Be sure to
maintain the consistency of the + (red)
and – (black) speaker connections by using
the markings on the wire’s insulation.
IMPORTANT: On all the speakers, connect
the red terminal to the bare wire lead that
has the “+” sign on it’s insulation. Connect
the black terminal to the other bare wire lead
that has either the word “Boston” or the wire’s
identification information on it.
Left and Right Front Satellites
and Center Channel
Using the five-way binding posts: The binding
posts permit easy connection to banana plugs,
pins, spade lugs, and bare wire. The metal sur-
faces are plated with gold to prevent corrosion.
NOTE: Before using banana plugs, first remove
the red and black plastic CE safety insert caps.
Surround Satellites
Push down the buttons and insert the wire
where shown. Be sure to connect + to + (red)
and – to – (black).

Speaker Connection
Center Channel Speaker
Connect the short speaker cable, with the green RCA plug, between the green jack on
the DigitalTheater 7000 subwoofer marked center and the speaker cable jack on the center
channel speaker.
Connect the control cable, with blue mini-DIN plug on both ends, between the jack on
the DigitalTheater 7000 subwoofer marked control and the control cable jack on the center
channel speaker.
Satellite Speaker Connections
There are four satellite speakers, two for
the front and two for the rear. The larger
front speakers use the shorter cables,
and the smaller rear surround speakers use
the longer cables. Connect them as shown:
Plug the white plug of the short speaker
cable into the jack labeled left front.
Plug the red plug of the short speaker cable
into the jack labeled right front.
Plug the white plug of the long speaker
cable into the jack labeled left surround.
Plug the red plug of the long speaker cable
into the jack labeled right surround.

DT7000 Manual 11/99 rev2 11/24/99 12:19 PM Page 13

Input Connections
DVD in: The the DigitalTheater 7000 may
be connected to the digital output from any
DVD player.
Note: DigitalTheater 7000 cannot be con-
nected to the AC-3 output from a laserdisc
player since a laserdisc is RF modulated. If
you wish to use a Dolby Digital laserdisc play-
er (with an “AC-3 RF output”), consult your
dealer for a suitable adaptor.
To make the connection, use the black digital
input cable. Plug one end into the digital
output of the DVD player and the other into
the black digital terminal on the subwoofer
back panel.
DSS in: The DigitalTheater 7000 may be con-
nected to the digital output from any DSS
satellite television system that provides a digi-
tal audio output. To make this connection, use
an optical digital cable like our DC-12 (not
included — for more details, contact your
dealer or Boston Acoustics directly).
Plug one end into the digital output of the
DSS unit and the other into the DSS jack on
the subwoofer back panel.
Note: Depending on it’s digital
output, any digital source
(DVD, MD, CD, satellite) can be
connected to either the optical
or coaxial (wired) digital inputs.
VCR and Audio in: The two stereo analog
inputs on the DigitalTheater 7000 may be
connected to any stereo analog source.
Typically this will be a stereo TV, Hi-Fi VCR, or
CD player. To make the connection, use the
analog stereo cable. Plug one end into the
audio outputs of the source unit and the other
into the appropriate terminals on the sub-
woofer back panel. Make sure the correct
color plug is connected to the correct color
jack: red to red and white to white.

Center Channel Display
Alphanumeric Display
This display shows the chosen input and the setting for system master volume, and the individual
channel levels (“trim levels”) for the center speaker, surround speakers, and subwoofer. The
master volume is numbered between 0 and 80, the trim levels for the center and surround speak-
ers are between –9 and +9, and the trim level range for the subwoofer is between -9 and +15.
The display dims after 5 seconds. When DigitalTheater 7000 is muted, the display reads “mute”.
The system can be unmuted by pressing the mute button, the volume up or down buttons, or any
input or system mode button. Following a choice of input or mode, the display also shows the
audio format (Dolby Digital, etc). After making any adjustments, the display will return back to the
chosen input and master volume and will then dim after 5 seconds.
Mode Group
Dolby Digital
This LED illuminates when the user has selected either the DSS or DVD input, and the
system’s decoder has detected a Dolby Digital signal.
night mode
For low level listening, (late at night, for example), the quietest passages can be difficult to hear
and the loud passages are often too loud. The night mode reduces the system’s dynamic range
(the difference between loudest and softest sounds) so the quiet parts of the program are clearly
audible even at low volume, while attenuating the loudest passages so others aren’t disturbed.
NOTE: The night mode can only be used when Dolby Digital is active. Because it is software-
dependent, its effect can be subtle, depending on the particular program.
PCM
This LED illuminates when the user has selected either the DSS or DVD input, and the
system’s decoder has detected a PCM signal.

format. NOTE: Programs recorded in mono
will appear only in the center channel when
surround is activated.
Many listeners enjoy the three-dimensional
effect of regular stereo material played
through the Surround decoder.
previous When using the remote to con-
trol your television, pressing this button
reverts to the previously viewed channel
(if your television has this function).
Programming the Universal Remote Control
This universal remote is pre-programmed for
hundreds of different devices.
Install the 4 “AAA” batteries in the remote.
Orient the batteries (+ or -) as shown
in the battery compartment.
For your TV, VCR, cable box, DSS, or DVD
player, look up the three-digit code for your
particular model in the included booklet.
Press the button for the unit you wish to
program—TV, VCR or cable box. The
LED on the remote will blink.
• The VCR button can also be used to
program DVD player codes, in place of
the VCR.
• The cable button can also be used to
program DSS codes, in place of the
cable box.

Hold the setup button on the remote
control for about three seconds, until the
LED on the remote blinks twice.
Enter the three-digit code for your particu-
lar device. The LED on the remote will blink
once after the first two numbers are
entered, and twice after the last number is
entered to signify it has accepted the pro-
gramming. Example: 1 (blink), 2 (blink), 3
(blink-blink). A single long blink indicates
an invalid key sequence.
Test the remote control on your device by
pressing power on or off.
If the remote does not appear to be working,
check that the right code was programmed.
Many manufacturers have multiple codes for
different devices; if the first code doesn’t
work, try a different code. Make sure the LED
on the remote blinks every time a button is
pressed. If not, be certain the batteries are cor-
rectly installed or replace the batteries in the
remote control.
Button Reassignment to Control
Different Devices
You might have two devices that would be
controlled by the same button (a VCR and a
DVD, for example, each controlled by the VCR
button, or a cable box and DSS, each con-
trolled by the cable button). In that case, you
will have to reassign one of the other buttons
to control that device.
Example: If you have a VCR and DVD player,
you will need to reassign the cable button to
control the DVD player
Press setup
Press 992 on the numeric keypad
Press the source button (in this example,
the VCR button)
Press the destination button (in this
example, the cable button)
The cable button is now another VCR button,
which can be used to control a DVD player.
Program the remote as described in steps 1-4.

Press test tone, and the test tone is heard
moving clockwise from speaker to speak-
er at 2 second intervals. The center chan-
nel display indicates the speaker under
test. The order should be left front, cen-
ter, right front, right rear and left rear. (No
test tone is heard from the
subwoofer. Adjust the subwoofer level
independently of the other channels
according to personal taste or to com-
pensate for the effects of room place-
ment). If the tone does not move contin-
uously from speaker to speaker then one
or more speakers is not connected to the
correct output on the subwoofer.
As the test tone rotates around the speakers,
you may notice that some speakers are louder
or softer than others. This is not due to any
defect, but to the difference in room acoustics
at different locations. The speaker levels
should be individually adjusted so they all
appear to have the same loudness at the lis-
tening position.
To adjust a specific speaker’s volume—
Press the button for the speaker you wish
to adjust. The display on the center chan-
nel speaker will indicate for the speaker
selected and the test tone will continue
to circulate.
Press the volume up or down button to
raise or lower the level of the selected
speaker. After 5 seconds, the function of
the volume button reverts to Master
Volume control.
Press test tone again to turn it off.
To adjust the subwoofer volume—
Press the subwoofer button (the display
indicates the subwoofer is undergoing
adjustment).
Press the volume button to raise or lower
the subwoofer level.
Even after calibrating the system, you may
want to adjust the loudness levels of the
center, satellite, or subwoofer channels to
personal taste. Speaker levels can be adjust-
ed at any time by selecting the speaker and
using the volume control.

Initial Setup – Test Tone
Before using the system, the relative speaker levels should be calibrated for optimum perform-
ance. This is easily accomplished by using the system’s built-in test tone to match the levels of the
front and rear channels. The test tone button on the remote control generates the test tone for
calibrating the speakers.
