Description

Quality theater audio for the desktop has arrived. Using an internal Dolby

Digital surround processor, the

Digital BA7500 delivers 5.1 movie audio from your PC’s DVD-ROM without the need for a separate

receiver or decoder. Four Boston SST™ (Slimline SpeakerTechnology™) satellites, an amplified

subwoofer and the processor’s“virtualized”center create six distinct cinema sound fields. With a 4-

channel sound card, it brings multi-channel PC gaming to a new level of realism. As a stereo music

system, the BA7500 has maintained the highest level of fidelity, equal in performance to some shelf

monitors.

Building on Boston’s proven 6½

bandpass subwoofer, the technological highlight of the Digital BA7500 is

the four SST satellites. Boston sets the standard:The technology found in the SST’s allows us to deliver

the same high-fidelity audio found in Boston’s larger home theater products and still maintain a sleek,

attractive profile. Front pedestal stands, rear tower stands, a desktop audio control pod and extra-long

surround cables make for easy 3D positioning and operation. Desktop controls include MasterVolume,

SurroundVolume, Surround Balance and Subwoofer Level. Each satellite is protected by magnetic

shielding to prevent video interference.

1. Front Speaker Assembly

) For desk or shelftop positioning, use the 3 desktop

stands and 1 integrated audio control pod/stand

(normally placed on right side of monitor). Simply slide

each stand's lip into the SST satellite speaker's

underside groove.

) Attach rubber pads to bottom tips of each desktop

stand. The rubber pads absorb vibrations between the

speaker and the desktop for a cleaner sound.

) Optionally, the two rear speakers (or all four) may

be wall mounted using the formed keyhole on the rear

panel of each satellite speaker. Any standard nail,

picture hook, etc. will work. (Not included. Consult a knowledge-

able installer about the proper hardware to use on your wall.)

) Connect each of the front two SST satellites to

their respective red or white RCA jack on the rear of

the subwoofer (labeled "Front Speakers"). Red is the

right front; white is the left front.

) Adhere subwoofer's rubber feet to each corner.

2. Rear Speaker &Tower Stand Assembly

) First, snap on the slide caps to the top of each tower

tube. Then feed the connection cord from each SST

satellite down through the tube. Next, slide each

satellite speaker on to top of tower tube, making sure

the cords are not being pinched. Finally, with the cord

passing through the bottom of the tower tube, slide on

each of the three stability legs. The cord should pass

freely through the intersection of the three stablility legs.

) Using the supplied 8"

adapter cord, plug the pink

end into the phono jack labeled "Rear Speakers" on the

of back the subwoofer. Next, connect each of the rear

satellite cords to their respective red or white RCA jack

on the end of the 8"

adapter cord; red to red, white to

white.

NOTE: For proper positioning, the right rear speaker

should be behind your right shoulder when facing your

computer monitor, and the left rear speaker should be

behind your left shoulder when facing your computer

monitor.

NOTE: Words in bold are parts included in your package; see appendix for parts list and illustrations.

Back of subwoofer

) My sound card has 2 STEREO LINE OUTPUTS

(4-channel): For sound cards with a 4-channel

gaming configuration, use your unified stereo cable

(see part illustration in appendix). Connect the green

and purple end of the unified stereo cable to the

green and purple inputs at the subwoofer (these are

labeled "Front" and "Rear" respectively on the back of

the subwoofer). On the opposite end of the unified

stereo cable, connect the green plug to the sound

card's front output (normally labeled "1", "front" or

green), and the black plug to the sound card's rear

output (normally labeled "2", "rear" or black). You will

not need your digital RCA cable for this setup.

) My sound card has 2 STEREO LINE OUTS and

a DIGITAL (S/PDIF) OUT: For sound cards with 2

stereo outputs and an added digital output on the

same card, use the unified stereo cable supplied

(see part illustration in appendix) and connect the

purple end of the unified stereo cable to the

subwoofer's "Rear Analog Input". Connect the

opposite black end of the unified stereo cable to the

sound card's rear output (normally labeled "2", "rear"

or black). You will not need to use either of the green

ends with this setup. Next, using your digital RCA

cable (see part illustration in appendix), connect one

of the black ends to the subwoofer's "Digital Input".

The opposite end of this digital RCA cable should

plug into your sound card's digital S/PDIF output.

NOTE: It may be necessary to use the RCA-to-

phono adapter (see part illustration in appendix) if

your card's digital output is a phono jack instead of a

coaxial.

) Connect the system's control pod cable

(blue) to the "Control" jack (also blue) on the

back of the subwoofer.

STOP: For step

'i'

you will need

to carefully identify which type of

sound card setup you have:

i4.

) My sound card has 1 ANALOG OUT-

PUT: Using your unified stereo cable (see

part illustration in appendix), plug the green

end into the subwoofer's "Front Analog Input",

and the opposite green end into the sound

card's single audio output. You will not need

the digital RCA cable or the purple and black

ends of the unified cable for this setup.

SPECIAL FEATURE: When operating as a

3-piece (or front channel input only), the

system has the ability to create a Virtualized

Dolby Surround effect; use Surround Vol.

SEPARATE DVD DECODER CARD: Using the unified

stereo cable (see part illustration in appendix below),

connect the green and purple end of the unified stereo cable

to the green and purple jacks on the back of the subwoofer

(these are labeled "Front" and "Rear" respectively on the back

of the subwoofer). On the opposite end of the unified stereo

cable, connect the green plug to the sound card's front output

(normally labeled "1", "front" or green), and the black plug to

the sound card's rear output (normally labeled "2", "rear" or

black). Next, using the digital RCA cable (see part illustra-

tion in appendix below), connect one of the black ends to the

"Digital Input" on the back of the subwoofer. The opposite

end of the digital RCA cable should connect to the DVD

decoder card's digital S/PDIF out. NOTE: It may be neces-

sary to use the RCA-to-phono adapter (see part illustration

in appendix below).

) Plug in power cable/transformer into back of

subwoofer and any available AC outlet.
