Before you begin...
We would like to iHanK you for purchasing the Bose^ AM-5'“
Acoustimass''' speaker system. We are confident that the
acfvanced technology and quality construction ot the AM-5
system will provide you with a litetirTK ol musical listening
pleasure.
The operating principles and wiring configuration of the
AM S system are significantly different from those of conven
tional speakers. This not only allows the AM-5 astern to
provide you with great sound, but also offers ptacement
fienfiiiity not available from conventional speakers. For best
results, and an easy installation, please take the time to
read this owner's guide.
Unpacking the AM-5 System
After opening the carton, remove all packaging material and
carefully lilt out the components of the AM-S system. Save
all the cartons and packing material in case the system
needs to be transporied at a later lime, if any of the com
ponents appear damaged, do not attempt to use the
system. Instead, repack the system in its original carton
and notify your authorized Bose dealer immediately.

Setting Up the System
The AM-5 system otters many advantages not available from
a conventional speaker astern. For one, the system adjusts
to deliver the combination of reflecled and direct sound opti
mal lor any listening environment. For another, the system
delivers this lifelike combination of reflected and direct sound
while using very little of your living space.
Before you can install and adjust (he system's componenfs.
lake a minute to familianze yourself with them. M)ur system
should include;
2 Cube speaker arrays

4 Wires
A. Select the location where you intend to place Ihe tell and
right cube speaker arrays. Note that wires from the arrays
connect to (he Acouslimass module, so you should
locate the cube speaker arrays so that the wires will reach
the location you chose for №e module.
Note: White the wires provided are adequate for most instailatrons. you may increase the distance behveen the cube
speaker arr^ and the Acouslimass module by splicing m
additional
wire, and mal« sure you maintain the correct phase (" " to
" -I-' and * -" to" - ’), and properly connect the wires.

cube of each cube speaker array, you can adjust the
spatial balance of your system to match your room or
musicaltaste.
Though there is no ‘correcf position (or the cube

are spaced 6 to 12 feet apart (aoproximately 1.8-3.6 m).
However, ^u can still achieve excellent results with sepa
ration as little as 3 feet (approximatefy 1 m) or as great as
15 feet (approximately 4 5 m). Note (hat when you are
using a balance of reflecteo and direct sound, the switch

D. 'A)u can also use the cube speaker arrays in direct mode
(with both cubes facing forward). While this eliminates
the bendits of combining direct artd reflected sourM], it
may be ^>prQpriate for very small listerúng areas (like
desks or cúbreles). When used in this mode, the switch
on the back of each array should be sei to ihe ‘Direcr
position.
E. The Acoustimass'* module can be located virtually any
where in your lislening room (Figure 2) in either a vertical
or horizontal position. Its unique Acoustimass'" speaker
technology de!ii«s room filling bass from almost any
where. Feet free to hide the Acoustimass module under a
bed or table, or e/en behind a sofa. Just remember not to
block the two tournl openings in the end of the unit. M)u
should allow at least 2 inches (approximately 5 cm) of
open space between these openings and the wall or
oiher surface.
Unlike conventional lloorstanding or bookshell speakers,
you can ñne tune the bass response of your AM-5 sys
tem without compromising accurate stereo imaging Just
change the location of the Acoustimass '' module within
your listening room. For typical listening environments,
positioning the module along a wall 3 to 5 feet (approxim^efy 1 to 1.5 mders)from a com& provides a normal
balance of frequencies from your AM S system. Moving
the module closer to Ihe walls and/or corners of your
room win increase bass response, while moving H
towards the center of your room wll decrease it. tn most
moms, if should be reasonably ea^ to choose a location
which is convenient, yet provides pleasing bass response.
F The cube speaker arrays of your AM 5 system are mag
netically shielded (or use with video systems. This
allows you to position the cube speaker arrays close to

wall outlet.
Note; Many receivers slate *use with 8*16 ohm
speakers '. While the AM-5 system is rated at 4 ohms
by lEC standard, the speaker s impedance actually
averages between 6 and Ô ohms, over most ot its
ODeratKKi range Therefore, the AM-5 should be
compatible with any quality receiver or amplifier
This includes electronics that call out use only
