For your protection, please read these safety
instructions completely before operating the appli-
ance, and keep this manual for future reference.
Carefully observe all warnings, precautions and
instructions on the appliance and described in the
operating instructions supplied with the appliance.
INSTALLATION
Water and Moisture - Do not install the appli-
ance near water: for example, near a bathtub, wash-
bowl, kitchen sink, laundry tub, in a wet basement,
or near a swimming pool.
Heat - Do not install the appliance near sources
of heat such as radiators, heat registers, stoves, or
other appliances that produce heat.
Ventilation - Situate the product so its location
or position does not interfere with its proper
ventilation. For example, you should not place the
product on a bed, sofa, rug, or similar surface that
might block the vent openings, or placed in a built-in
installation, such as a bookcase or cabinet that
might impede the flow of air through the
ventilation openings.
Wall or Ceiling Mounting - If your appliance can
be mounted to a wall or ceiling, mount it only
as recommended.
Accessories - Do not place this product on an
unstable cart, stand, tripod, bracket, or table. The
product may fall, causing serious injury to a child
or adult, and serious damage to the product. Use
only with a cart, stand, tripod, bracket, or table
recommended by the manufacturer, or sold with the
product. Any mounting of the product should follow
the manufacturer’s instructions, and should use
a mounting accessory recommended by
the manufacturer.
USE
Power Source - Connect the appliance to a pow-
er supply only of the type described in the operating
instructions or as marked on the appliance.
Power Cord Protection - Route the power cord
so that it is not likely to be walked on or pinched by
having objects placed on it, paying particular atten-
tion to the plugs, receptacles, and the point where
the cord exits from the appliance.
Grounding or Polarization - Do not defeat the
grounding or polarization feature of the AC power
cord. If your AC receptacle will not accept the power
cord plug, contact your electrician to install a proper
AC receptacle.
When not in use - Unplug the power cord from
the outlet when left unused for a long period of time.
To disconnect the cord, pull it out by grasping the
plug. Never pull the plug out by the cord.
AC Receptacle - Check to make sure that the AC
receptacle holds the power cord plug firmly and se-
curely. If the power cord plug is loose, contact your
electrician to replace the defective and unsafe AC
Foreign Objects - Be careful that foreign
objects and liquids do not enter the enclosure
through openings.
Cleaning - unplug this product from the wall
outlet before cleaning. Do not use liquid cleaners or
aerosol cleaners. Use a damp cloth for cleaning.
SERVICE
Unplug the appliance from the wall outlet and
consult qualified service personnel when:
• The power cord or the plug has
been damaged
• A solid object or liquid has fallen into
the cabinet.
• The appliance has been exposed to rain
or moisture.
• The appliance does not appear to operate
normally or exhibits a marked change
in performance.
• The appliance has been dropped, or the
enclosure damaged. Do not attempt

Loudspeakers have difficulty working
with the electronic signals supplied by
an amplifier. These difficulties cause
such major phase and amplitude dis-
tortion that the sound reproduced by
speaker differs significantly from the
sound produced by the original source.
In the past, these problems proved
unsolvable and were thus delegated to
a position of secondary importance in
audio system design. However, phase
and amplitude integrity is essential to
accurate sound reproduction.
Research shows that the informa-
tion which the listener translates into
the recognizable characteristics of a
live performance are intimately tied into
complex time and amplitude relation-
ships between the fundamental and
harmonic components of a given musi-
cal note or sound. These relationships
define a sound’s “sound.”
When these complex relationships
pass through a speaker, the proper
order is lost. The higher frequencies
are delayed. A lower frequency may
reach the listener’s ear first or perhaps
simultaneously with that of a higher fre-
quency. In some cases, the fundamental
components may be so time-shifted
that they reach the listener’s ear
ahead of some or all of the
harmonic components.
This change in the phase and ampli-
tude relationship on the harmonic and
fundamental frequencies is technically
called “envelope distortion.” The listener
perceives this loss of sound integrity
in the reproduced sound as “muddy”
and “smeared.” In the extreme, it can
become difficult to tell the difference
between musical instruments, for exam-
ple, an oboe and a clarinet.
BBE Sound, Inc. conducted ex-
tensive studies of numerous speaker
systems over a ten year period. With
this knowledge, it became possible to
identify the characteristics of an ideal
speaker and to distill the corrections
necessary to return the fundamental
and harmonic frequency structures to
their correct order. While there are dif-
ferences among various speaker designs
in the magnitude of their correction, the
overall pattern of correction needed is
remarkably consistent.

We recommend that if at all possible, a BBE 282i which
requires service be sent to our facility in Huntington Beach,
California. We request that a “RETURN AUTHORIZATION ”
be issued by the dealer from whom you purchased the unit.
If this is not possible, call BBE Sound, Inc. directly at (800)
233-8346, extension 116 to obtain a “RETURN AUTHO-
R IZ ATI O N .” Include a copy of the bill of sale with the unit
when it is shipped to BBE Sound, Inc. so that the service can
be expedited.
As the repair turnaround time is minimal, we request
that the unit be sent to BBE Sound, Inc. We also need to
add reliability data to our files so that future revision may be
undertaken, if necessary, to improve the product. If unit has
been purchased outside the US, please contact your
national distributor.
Maintenance of the BBE 282i is limited to proper clean-
ing of the unit with mild household cleaner such as Formula
409™ or Windex™. The chassis is steel , the casing is an
aluminum extrusion. Both are finished with a durable polyure-
thane paint.
There are no user replaceable parts and the unit should
not be opened for any reason unless you are a qualified
technician. Calibration should be performed if parts are re-
placed or if a performance check-out indicates a problem with
calibration. Long term use has shown that over the life of this
unit there is little or no drift of the components in the BBE
282i which would cause a change in calibration.
