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

Four-channel sound card compatibility

1. Front Speaker Assembly
a ) 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).
b ) Making sure speaker cables are free, slide on front
speaker pedestal stands.
c ) 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
a ) Connect the right front
satellite's control cable (blue) to the
"Control" jack (blue) on the back of
the subwoofer.
b ) 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
a ) 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.
b ) 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).
c ) Plug in power cable/transformer into
back of subwoofer and available AC outlet.
