Bose Acoustic Wave Cannon System II User manual

The Bose®Acoustic Wave®CannonTM
System II (AWCSTM II) loudspeaker is the
bass component for installed Bose sound
systems designed for high quality reinforce-
ment of voice and music. The AWCS II
includes system equalization, when com-
bined with a 402TMC, 502TMC or 802®C
Series II systems controller. These systems
controllers, with the OC-1 option card
installed, assure smooth, accurate spectral
response across the entire operating
range of the AWCS II system while pro-
viding loudspeaker protection and two
independent mid/high frequency signal
channels. Fourth order subsonic and
ultrasonic band-limiting filters use power
efficiently, reducing harmonic distortion,
and high-excursion cone instability.
The Acoustic Wave®Cannon System II
loudspeaker provides extended band-
width high performance in permanent
installations. When mounted near solid
walls, ceilings, or floors its acoustic bass
loading delivers greater low frequency
sound pressure.
Each AWCS II enclosure houses a single
high power twelve inch woofer, mounted
between two different length waveguides.
Molded flanges include steel reinforcing
plates that provide secure mounting points.
The 402C, 502C, and 802C Series II
systems controllers are 1U rack devices.
Each provides crossover functions, active
electronic equalization, and dual channel
signal processing for the AWCS II system
in combination with either Bose 402,
502A, or 802 loudspeakers. Each systems
controller features -10/+4dB-V input
sensitivity switches, all-balanced inputs
and outputs, -18/+3dB bass level control,
bass mono sum switch, automatic output
muting during turn on/off, and a secure
rear-panel operating mode switch.
The OC-1 option card must be installed
in the systems controller. It provides an
additional bass active equalization circuit
when the unit is operated in mode switch
position 4. A proprietarycircuit in the OC-1
constantly monitors amplifier voltage and
assures that woofer excursion does not
exceed the safe operating region. This

results in very high continuous SPL
capability and superior low frequency
output without the need for external
limiters/compressors. The OC-1 is supplied
with a cable which is used to sense the
output voltage of the amplifier for AWCS II
system.The cable must be connected to
the four pin DIN connection on the rear
panel of the systems controller and the
amplifier output for the AWCS II system.
The system will automatically mute after
approximately one minute if this connec-
tion is not made.
The Bose®Acoustic Wave®CannonTM
System II loudspeaker provides a flexible,
building-block approach to meet the sound
reinforcement requirements of a wide variety
of applications. You will find detailed
installation and system design guidelines
in the Bose®Acoustic Wave®CannonTM
System II Loudspeaker Owner’s Guide.

Architects’ Specifications
The maximum acoustic output of the
bass enclosure shall be 115dB-SPL
from 25Hz to 125Hz, with measurements
referenced to a full-bandwidth pink-noise
input at 1 meter at the enclosure’s rated
power. Its power handling capacity shall
be 300 Watts continuous, referenced to
IEC noise for 100 hours.
The enclosure shall be made of custom
extruded polyvinyl chloride pipe. Outer
dimensions of the enclosure shall be 150"
(L) x 17" (W) (3.81 x .43 m); its weight
shall be 63 lb (29 kg).
The low-frequency device shallbe the
Bose®Acoustic Wave®CannonTM
System II loudspeaker.
The AWCSTM II system shall be provided
with a separate system controller, to be
connected before the input(s) of the sys-
tem power amplifier(s). An OC-1 option
card, installed in the systems controller,
shall replace the bass active equalization.
The fixed, 2-channel system controller
shall provide active electronic equaliza-
tion and crossover functions. It shall in-
clude an operating mode switch, input
sensitivity switch, low-frequency output
level control, and mono sum switch. The
system controller shall use screw-type
terminal strips for balanced input and
output wiring connections. Outer dimen-
sion of the systems controller shall be
1.75" (H) x 19.0" (W) x 8.0" (D) (4.4 x
48.3 x 20.3 cm). It shall fit in the single
space of a standard 19" equipment
rack for mounting. Its weight shall be
5.5 lb (2.5 kg).
The electronic controller shall be the
Bose 402TMC, 502TMC or 802®C Series II
systems controller.
The Bose Acoustic Wave®Cannon
System II (AWCS II) loudspeaker is
covered by a 5-year, transferable
limited warranty. The Bose 402C 502C
and 802C Series II systems controllers
are covered by a 2-year, transferable
limited warranty.
