General Description
The Bose
®
Model 1800-VI professional
stereo power amplifier is a high per-
formance amplifier designed for use with
all Bose Professional Products loud-
speaker systems. The unit offers high
power in a rugged, lightweight (33 lb)
package that is only two rack space
units (3.5") high. The amplifier is suitable
for portable or permanent installations.
The 1800-VI amplifier is a high powered,
two channel amplifier delivering 450
watts per channel into 8Ω, 600 watts per
channel into 4Ω, or 1400 watts bridged
into 8Ω. The 1800-VI amplifier is de-
signed to accept Active Equalization
plug-in circuit cards for all Bose Profes-
sional Products loudspeakers, eliminat-
ing the need for a separate controller.
The Model 1800-VI amplifier includes
the standard EQ module, designed to
hold up to two EQ cards. An optional
ACM-1
amplifier control module, which
also holds up to two EQ cards, is
designed to establish network control of
the amplifier. This network link makes
remote operation of signal level and
power on/off functions possible. The
module also provides amplifier monitor-
ing capability. Using the graphical user
interface of the ACM-1 module software,
settings like amplifier output, output
load, and temperature can be checked
routinely.
The Model 1800-VI amplifier accepts both
balanced
and unbalanced inputs from
TRS, XLR or
stripped wire connections.
The rear panel
allows for an unused
parallel input or the actively equalized
line level output to be connected to
another device.
Model 1800-VI amplifier detailed installa-
tion and operating instructions are
provided in the Model 1800-VI and
1600-VI Professional Stereo Power
Amplifier Owner’s Guide.
