1Full bandwidth pink noise is applied to the
Panaray system digital controller and amplified to
a level at the speaker terminals corresponding to
the long-term rated power handling of the speaker.
The average sound pressure level (dB-SPL) is
measured at 1 meter from the speaker in an
anechoic environment. The peak maximum
acoustic output is the peak SPL possible with the
maximum recommended amplifier power using
musical program material.
2Full bandwidth pink noise is applied to the
Panaray system digital controller and amplified to
a level at the speaker terminals corresponding to
one watt as referenced to the nominal impedance.
The average sound pressure level (dB-SPL) is
measured at 1 meter from the speaker in an
anechoic environment.
3Full bandwidth noise, meeting the International
Electrotechnical Commission standard #268-5, is
applied to the Panaray system digital controller
and amplified to a voltage at the speaker terminals
corresponding to the power handling of the
speaker. The speaker must show no visible or
measurable loss of performance after 100 hours of
continuous testing.

System Description
Component Description
The Bose®Panaray®502®system is a
fully modular system which
represents significant advances in
loudspeaker array, low-frequency
transducer, and system control
technology. Components of the basic
Panaray 502 system, which are sold
separately, include two 502 A con-
trolled arrays, one 502 B Acousti-
mass®enclosure, and one Panaray
system digital controller. This basic
system provides up to 122dB peak
SPL (at 1 meter, driven with maxi-
mum recommended amplifier power)
over the 55Hz to 15kHz range.
Extensive research has yielded new
technology in array design which,
using a proprietary arrangement of
Bose 4.5-inch full-range drivers,
results in tightly controlled horizontal
and vertical beamwidth, and ex-
tremely smooth band-to-band
directivity. The system also features
a new, compact low-frequency
enclosure using Bose-patented
Acoustimass technology. The
Panaray 502 system is a highly
aesthetic voice or music sound
reinforcement system for permanent
audio installations in theaters,
auditoriums, churches, nightclubs,
transportation facilities, and other
places where people gather to be
entertained, enlightened, or informed.
The 502 A controlled array is a mid-
to high-frequency component of the
Panaray 502 system. It features five
new-design 4.5" (11.4 cm) helical
voice coil drivers in a slim, elegantly
designed enclosure. The result is
natural sounding, extremely even
coverage at all frequencies over the
entire listening area.
localizable sound source, which
allows it to be unobtrusively in-
stalled apart from the 502 A arrays.
The enclosure is fitted with 10x
safety-rated attachment points (top
and bottom) for mounting in a
variety of orientations.
Two-point suspension is easy to
accomplish using the Bose CSB-5B
suspension bracket. The 502 B is
available in both Professional Gray
and Arctic White, and is covered
with a scratch-resistant vinyl, which
can be painted to match any décor.
The Panaray system digital control-
ler is a single rack-space device
which provides crossover functions,
active electronic equalization, and
dual-channel signal processing for
both the 502 A and 502 B.
An optional plug-in card is available
for Bose amplifiers, which allows
502 A controlled arrays to be
combined in a sound-system
design with the Acoustic Wave®
Cannon™system.
The Panaray 502 system includes a
complete line of accessories for
suspending or mounting both the
502 A and 502 B in a wide variety of
configurations.
It can be used with either the 502 B
Acoustimass enclosure for full-
frequency sound reinforcement, or
separately for voice-only reinforce-
ment systems.
The 502 A controlled array is de-
signed for installation in a variety of
configurations, using its integral 10x
safety-rated attachment points, and
Bose suspension and mounting
accessories. The baffle and rear panel
are constructed of high-strength
structural foam, and the speaker grille
is constructed of a durable perforated
steel. It is available in both Profes-
sional Gray and Arctic White, and
both the enclosure and grille are fully
paintable to match interior décor.
The 502 B Acoustimass enclosure
uses a single high-power-handling,
high-reliability 12" (30 cm) woofer.
This new Bose-designed low-
frequency transducer features a high-
temperature, 4" (10.2 cm) voice coil,
cast aluminum basket, and a high-
durability rubber surround. The 502 B
speaker provides clear, deep bass
reinforcement from a small enclosure,
using patented Bose Acoustimass
speaker technology. Its low cross
over frequency results in a non-
*Beamwidth is the -6dB point, in each one-third octave band, on a polar plot representing the
average within ten degrees of the horizontal and vertical planes about the array.
*Directivity is the ratio, in each one-third octave band, of the average response in the nominal 120º x 70º polar window, to the average response
over the entire solid angle about the source.

System Configurations
The Bose®Panaray®502®system
provides a flexible, building-block
approach to fit the sound reinforce-
ment requirements of many types of
applications, from nightclubs to
cathedrals. Detailed installation and
system design guidelines for the
Panaray 502 system are provided in
the Panaray 502 System Owner’s
Guide. For illustrative purposes, here
are some typical system configura-
tions:
Figure 1 shows a block diagram of
the basic Panaray 502 system,
consisting of one 502 B, two 502 A
speakers, one Panaray system digital
controller, and three channels of
amplification for a stereo system.
This system provides 115dB-SPL @
1 m average acoustic output. Addi-
tional low-frequency output can
easily be achieved by locating the
cabinet against large hard surfaces.
Figure 2 illustrates how components
can be added to the basic Panaray
502 system to achieve a variety of
SPL or coverage requirements. One
example of an expanded system
would be a small disco dance area.
In this application, four arrays at the
outer corners of the dance floor,
plus two 502 Bs on the floor adjacent
to the dance area, will deliver
approximately 118dB-SPL average,
with 130dB-SPL peaks, and all
components driven at maximum
recommended amplifier power.
Figure 3 shows how the Panaray 502
components can be interconnected
for a voice-only paging system. This
system is ideal for applications where
voice reinforcement is needed over a
large area, such as an airport termi-
nal or a train station. Through the use
of the Bose CVT-5 Constant Voltage
Transformer, multiple 502 As can be
installed in a 70/100V constant
voltage distributed system. (This
system operates from 130Hz and
above only, and is not recommended
for use where music is an integral
part of the program material.)

enclosures are covered
by a five-year, transferable limited
warranty.
