Bose® 802® Series II
Loudspeaker
The Bose 802 Series II sound components
provide a fully modular system designed
for high quality reinforcement of voice
and music.
Bose 802 Series II loudspeakers work with
the 802C Series II systems con
troller for
active equalization of the system.
The 802
Series II loudspeaker is preferred for
applications requiring a rugged, portable
enclosure, but can be used in permanent
indoor sound system installations.
The 802C Series II systems controller assures
smooth, accurate spectral response across
the entire operating range of the 802
Series II
loudspeaker. Sharp subsonic and
ultrasonic
band-limiting filters reduce
power waste,
stage noise, high-frequency
instability, and
interference. The systems
controller also
provides two independent
signal channels.

Each 802 Series II loudspeaker
uses
eight 4
1

" full-range drivers mounted
in
symmetric vertical pairs on a faceted
Articulated Array® baffle assembly. The
drivers feature low-impedance,
edge-wound aluminum voice coils,
12-ounce Ferrite V ceramic magnets, and
molded polyester frames. Their advanced
cone and motor system give them high
linear excursion capability and power
output.
Tuned reactive air columns reduce
distor
tion by controlling the cone
excursion
re
quired to reproduce deep bass
frequencies.
A built-in directivity control
circuit maintains
the vertical dispersion
pattern through the high-frequency range.
It also protects the drivers from
high-frequency overload.
The 802C Series II systems controller is a
single-rack sized device. It is capable of
providing crossover functions, active
elec
tronic equalization, and dual channel
signal
processing for both the 802 Series
II loudspeak
ers and the 502

enclosure. It features
-10/+4dB-V in
put sensitivity switches,
all-balanced inputs
and outputs, -18/+3dB
bass level control,
and a bass mono sum
switch. It also provides
automatic output
muting on turn-off, and a
secure
rear-panel operating mode switch.
