Before you begin
Your Bose® 201 ®Series IV DirecVReflecting@ speakers are designed to create alistening
experience that
is very similar to alive concert. There are two basic ways to place your
speakers
in aroom. Try both and let your personal taste determine which is best.
The first way takes advantage
of Stereo Targeting® technology, with the tweeters firing
inward to create
an intimate or focused sound pattern (Figure 1, position 1). This may be the
best choice for use with avideo system, or if your room lacks one or more reflecting walls.
The second way allows the tweeters to fire outward to disperse awider, more spacious
sound (Figure
1, position 2). You may find this best for music recorded in live settings.
Your
201 Series IV speakers are significantly different from conventional ones, so be sure to
read this owner's guide. It will help you set up and use your speakers properly, for the
greatest enjoyment.

page 2
of this guide and on your warranty card.

Select the locations for your 201" speakers
The following guidelines are intended to help you find the best sounding location for your
new speakers:
•Listen to both speaker sound patterns shown on page
4, Figure 1. Choose the one you
prefer.
1. First, aim the tweeters inward as shown in Figure 1, position 1. The tweeters are
directly behind the angle on the front of each speaker. Listen
to music.
2. Next, aim the tweeters outward, as shown in Figure 1, position 2, by interchanging
the left and right speakers. Listen
to the same passage of music.
•Place the speakers 4
to 12 feet (1 .2 to 3.6 m) apart with the back of the speakers no
more than 18 inches
(45 cm) from the rear wall.
•Leave at least 12 inches
(30 cm) of space from the end of aspeaker to the side wall.
•Leave at least 18 inches
(45 cm) from the speakers to the floor and ceiling. Positions
closer to walls, floor, or ceiling will produce more bass.
•Avoid placing the speakers exactly halfway between the floor and ceiling.
Note: Bose" AS-3 speaker stands can extend your placement options. See 'Optional
accessories"
on page 10.
Caution: 201"speakers are specifically designed for placement on astationary shelf,
table, or stand.
00 not place them in avertical position. On smooth surfaces like marble,
glass, or highlypolished wood, vibrations may cause the speakers
to slide. So be sure to
attach the self-adhesive rubber feet to the bottom surface of each speaker for added
stability and protection. The feet go in the corners of the flat surface. inside the seam
00 not use these speakers in amoving vehicle. As supplied, the speakers are not designed
to be mounted on walls. 00 not mount them without consulting aqualified installer. Or.
check with Bose for details on the propermounting procedure. Improperly mounted speak-
ers may
fall, causing injury and damage. To contact Bose, please refer to the information

Choose the cord
Caution: Never use broken or frayed wiring. It can result in electrical shock or damage.
It is important to use the proper gauge (thickness) of speaker wire. Standard zip cord
(2-conductor, 18-gauge wire) works best for most applications.
You can find this wire at
most electrical and hardware stores.
You will need thicker wire if your speakers will be more than 30 feet (9 m) from areceiver or
amplifier. Refer
to the wire recommendations under "Technical information" on page 10, or
contact your authorized
Bose® dealer for more information.
Note: This wire may not be suitable for use inside finished walls. Check your local building
code requirements or contact an electrical installer for information.
Prepare the cord
Speaker cord consists of two insulated wires. The insulation around one wire is marked
(striped, printed, or ribbed). This marked wire is always positive (+). The plain wire
is always
negative (-). These wires correspond to the red
(+) and black (-) terminals on the speakers
and the receiver or amplifier.
At the ends of each cord, strip approximately
Y2 inch (12 mm) of insulation from both wires.
Twist the bare end of each wire, so loose strands will not touch across terminals. Be sure to
connect each wire to the proper terminal (positive to positive and negative
to negative).
Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully
Make the connections
Caution: Before making any connections. turn offyour receiver or amplifier and unplug it
from the AC power (mains) outlet. Not doing so may result in damage to your system.
Just press the terminal tab on the back of each speaker to insert the appropriate wire
(Figure
4).
1. Connect one speaker cord to your right speaker.
a. Attach the marked wire to the red (+) terminal.
b. Attach the plain wire to the black (-) terminal.
2. Connect the other end of the same cord to the RIGHT SPEAKER OUTPUT of your
receiver.
a. Attach the marked wire to the red (+) terminal.
b. Attach the plain wire to the black Hterminal.
3. Connect the second cord to the left speaker and
LEFT SPEAKER OUTPUT as described above.

Terminal connections

Check the connections
Check that all connections are made positive to positive (+ to +) and negative to negative
(- to -) (Figure 5). Make sure that no loose strands of wire touch across terminals. This
could damage your receiver or amplifier. Be sure the connections are secure before you
plug
in the receiver or amplifier and turn it on.

Test the speakers
To make sure your speakers operate correctly:
1. Place the speakers less than 6inches (15 cm) apart, facing each other.
2. Turn on your receiver, and set it to MONO (monophonic), if that is an option on your
model.
3. Set the balance control to normal (center position).
4. Play some deep bass passages of music through the speakers.
The sound should seem
to come from apoint between the two speakers. The bass should
be full and natural. lf it
is not, one of the connections may be reversed, causing the speak-
ers to play out of phase. Refer to "Make the connections" on page
6. To correct the
problem, make sure
all the wires are connected positive to positive (+ to +) and negative to
negative (- to -). Then repeat steps 1through 4 to re-test the speakers.

What to do
•Make sure the receiver or amplifier is plugged in and turned on.
•Check to be sure the AC power (mains) outlet is working.
•Disconnect any headphones plugged into the headphone jack.
•Make sure the receiver or amplifier is not set to MUTE.
•Refer to the owner's guide that came with your receiver or
amplifier.
•Check
all connections at both the speaker and the receiver or
amplifier end. Refer to "Make the connections" on page
6.
Correct any errors.
•Disconnect the working speaker from the receiver or amplifier.
•Switch the cord of the "faulty" speaker from its original receiver
or amplifier jacks to the other set ofjacks (the working
speaker was originally attached to those jacks).
-If the speaker now works, the problem
is in your receiver or
amplifier. Reconnect your speakers
to aworking unit.
- If there is still no sound from the speaker, continue below.
•Remove the cord from the working speaker and connect it
to the
"faulty" speaker and either channel of the receiver or amplifier
jacks.
-If the speaker now works, the problem was
in the original
speaker cord.
- If there is still no sound, the problem is in the speaker.
•Follow the same procedure for the problem of no sound from
one speaker,
as outlined above.
•Adjust the bass and treble volume controls on the receiver.
•Check the connections to make sure they are correctly
in phase
(positive to positive and negative to negative). Refer
to "Make the
connections" on page
6.
•Experiment with different room placements. Positions closer to
walls, floor, or ceiling will produce more bass.

Cleaning the speakers
Clean the surface of your speakers with asoft, damp cloth. Amild soap may be used, but
do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or
abrasives.
Do not use any sprays near the system or allow liquids to spill into any openings.
