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’sDVD-ROMwithout the need for a separate receiver or decoder. Four Boston SST™ (Slimline Speaker Technology™) satellites, an amplified subwoofer and the processor’s “virtualized” center create six distinct cinema sound fields. With a 4- channel sound card, it bringsmulti-channelPC 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-fidelityaudio 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 andextra-longsurround cables make for easy 3D positioning and operation. Desktop controls include Master Volume, Surround Volume, Surround Balance and Subwoofer Level. Each satellite is protected by magnetic shielding to prevent video interference.

This Package Contains:

1 Amplified subwoofer

2 Front SST satellite speakers with captive cords

2 Rear SST satellite speakers with 20' captive cords

3 Satellite speaker desktop stands

1 Audio controls pod/stand with captive DIN cable

1 Digital input RCA cable

1 Unified stereo analog cable for front and rear input 1 8" “Y” adapter cord for rear speaker output

4 Self-adhesiverubber feet for subwoofer

1 Pack of self-adhesiverubber feet for satellites 1 Transformer with power cord

1 RCA-to-phonoadapter

2 Rear surround tower stands

Additional Features:

a) For desk or shelftop positioning, use the 3desktop stands and 1 integratedaudio control pod/stand

(normally placed on right side of monitor). Simply slide each stand's lip into the SST satellite speaker's underside groove.

b) Attachrubber pads to bottom tips of each desktop stand. The rubber pads absorb vibrations between the speaker and the desktop for a cleaner sound.

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

d) Connect each of the front twoSST satellites to their respectivered orwhite RCA jack on the rear of thesubwoofer (labeled "Front Speakers"). Red is the right front; white is the left front.

e)Adhere subwoofer's rubber feetto each corner.

2. Rear Speaker & Tower Stand Assembly

 

f ) 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.

 

g) Using the supplied 8"Y 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 orwhite RCA jack

 

on the end of the 8" Y 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.

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

i2) 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 cableto 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.

i3) 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 cablesupplied (see part illustration in appendix) and connect the purple end of the unified stereo cableto the subwoofer's "Rear Analog Input". Connect the opposite black end of the unified stereo cableto 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 cableshould 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.
