GETTING STARTED
Before you begin
Thank you for choosing Bose® Companion® 2 Series II multimedia
speaker system. Unique features and Bose technologies make these
speakers a superior choice for upgrading your computer audio. They
also provide rich, full stereo sound from a second source, like a portable
MP3 or CD player.
Benefits of your Companion 2 speakers:
• TrueSpace
• Ported cabinet design provides clear, deep musical tones.
• Sleek design blends in with contemporary office décor.
Unpacking the carton
Carefully unpack your speakers and save all of the packing materials,
which provide the safest means for shipping or transporting.
If any part appears damaged, do not attempt to use it (Figure 1). Notify
your authorized Bose dealer immediately. Or, to contact Bose directly,
refer to the address sheet included in the carton.
WARNING: To avoid danger of suffocation, keep the plastic bags that wrap
these speakers out of the reach of children.

Choosing a speaker location
The angled design of these speakers allows them to direct sound
upward toward a seated listener. So placing them on a desktop is a
good choice. Magnetic shielding protects your computer monitor from !
interference when the speakers are positioned close to it.
Place the speaker that has a volume control knob on the front within
easy reach to the right of your computer. Place the other speaker on the
left (Figure 2).
Note: LEFT and RIGHT labels on the back of the two speakers can serve
as a placement aid.

Volume
control
You may prefer placing the RIGHT speaker on your left to more easily
reach the volume control and the headphone jack.
This does no harm, although it changes how you hear the left and right
stereo sound. For an accurate sound stage, the music recorded from
stage left during a live performance comes from the left speaker. Changing the placement of LEFT and RIGHT speakers alters that effect.
Connecting the speakers
A speaker cable is attached to the rear of the LEFT speaker. Insert the
free end of this cable into the jack marked TO LEFT SPEAKER on the
back of the RIGHT speaker (Figure 3 on page 8).

Two audio input cables are supplied with the speakers.

RCA audio in jacks. Insert the plugs at one end of this cable into the
jacks on the computer, matching red to red and white to white.
Two pairs of jacks on the back of the RIGHT speaker are labeled
AUDIO INPUT. Each pair includes a white jack marked L above a red jack
marked R (Figure 4 on page 9).
• Use the free end of the audio input cable to connect to one pair of the
AUDIO INPUT jacks.
1. Insert the white RCA plug into the white jack labeled L.
2. Insert the red RCA plug into the red jack labeled R.

Enjoying the sound

Volume control
To control your sound sources independently:
• Use your computer volume control, which may include an external
control as well as one on screen.
• Use the volume control on the second sound source.
To avoid constant adjustments, balance the volume levels:
1. On your computer and other sound source, set the volume so the
two are roughly equal in output. Make it about two-thirds the !
maximum volume on each.
2. Use the knob on the RIGHT speaker to adjust the volume as you
listen. Turn it right to raise and left to lower the volume (Figure 8).
A second option may be more convenient:
1. Turn the volume knob on the RIGHT speaker completely to the right
for maximum volume.
2. Use the volume control on each sound source (computer or player)
to adjust the volume as you listen.

USING THE SPEAKERS
Cleaning the speakers
Wipe the speakers using a soft, dry cloth. Do not use solvents, !
