General Description
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 controller 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.
Component Description
Each 802 Series II loudspeaker uses
eight 4

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
distortion by controlling the cone
excursion required 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
electronic equalization, and dual channel
signal processing for both the 802 Series
II loudspeakers and the 502

enclosure. It features
-10/+4dB-V input 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.
