BA4800

Powered Speaker System

4-Channel Surround Configuration

Description

The Boston Acoustics BA4800 is an analog 5-piece, 4-channel surround speaker system ideal for

computer gaming or any enhanced audio application at the desktop. The system includes 4

powered micro-satellites and a large, amplified, ported subwoofer for deep bass response. The

BA4800 performs best with PC sound cards offering 4-speaker output (e.g., 2 stereo outputs, front

and rear), but also sounds impressive as a 3-piece music system when connected to any head-

phone jack or line-level output (portable CD player, MiniDisc player, MP3 player, etc.). With added

features like MagnaGuard

magnetic shielding, stable rear tower stands, extra-long surround cable

connections and speaker-mounted controls, you not only get the renowned Boston Acoustics

sound but uncommon flexibility. For more information on Boston Acoustics or our line of home

theater and car products, visit us on the Web at www.bostonacoustics.com.

1. Front Speaker Assembly

) Connect the left front speaker's plug into the jack

on the rear of the right front speaker, (NOTE: satellite

speaker with audio controls should be on the right side

of your video monitor).

) Making sure speaker cables are free, slide on front

speaker pedestal stands.

) Attach rubber pads to bottom tips of each pedestal

stand. The rubber pads absorb vibrations between the

speakers and the desktop for a cleaner sound.

2. Input Panel Connections

) Connect the right front

satellite's control cable (blue) to the

"Control" jack (blue) on the back of

the subwoofer.

) Connect each of the audio

input cables (2 ea.) to your PC's

sound card. "Front Analog in"

(green) on the back of the sub-

woofer to the front analog output

on the sound card (usually labeled

"front", "1" or green). "Rear Analog

in" (purple) on subwoofer connects

to the sound card's rear analog

output (usually labeled "rear", "2"

or black).

3. Rear Speaker Assembly

) First, snap on the slide caps to

the top of each tower tube. Then feed

the connection cord from each

speaker 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 stability legs.

) With each of the two tower speaker

cords passing down through the tubes,

connect each plug to the respective

right and left "Rear Speaker" jacks on

the back of the subwoofer (red to red

and white to white).

) Plug in power cable/transformer into

back of subwoofer and available AC outlet.
