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.
System Configuration

The Model 1800-VI amplifier shall deliver
450 watts
of continuous power, both
channels driven, into 8Ωwith less than
0.2% distortion from 20Hz to 20kHz. The
amplifier shall deliver 600 watts of
continuous power, both channels driven,
into 4Ωwith less than 0.2% distortion
from 20Hz to 20kHz. In bridged-mono
operation, the amplifier shall deliver 1400
watts of continuous power into 8Ωwith
less than 0.2% distortion.
There shall be two parallel input
connec-
tors for each of the two input channels.
One of the input connectors shall be
capable of connecting to both a 1⁄4" TRS
and an XLR connector (only one input
connector can be accepted at one time).
The second input connector shall
consist
of a quick connect terminal block
Optional Equalizer
Card Information connector. The two output multi-way
binding posts shall be capable of accept-
ing either spade-lug, bare wire, or banana
connections. There shall be two 1⁄4" TRS
line level equalized signal outputs, cor-
res ponding to the two channels. This
signal shall be accessed after the internal
equalization card (if installed) and prior to
the internal amplification section.
The channel separation for the two
channels shall be greater than 65dB @
1kHz and greater than 55dB @ 10kHz.
The dynamic headroom shall be greater
than 1.0dB. The power bandwidth, from
5Hz to 40kHz, shall be +0dB, -3dB.
The frequency response, from 20Hz to
20kHz, shall be ±0.75dB. The damping
factor shall be at least 170.
The input impedance shall be 25kΩ,
unbalanced, each leg to ground and
50kΩbalanced. The high sensitivity shall
be 0.775 volts rms for rated power into
4Ω@ 1kHz, and 32mV rms for 1 watt
into 4Ω@ 1kHz. The low sensitivity shall
be 1.5 volts rms for rated power into 4Ω
@ 1kHz and 61mV rms for 1 watt into 4Ω
@ 1kHz.
The gain shall be 36.0dB, ±0.5dB with
the high input sensitivity configuration.
The gain shall be 30.3dB, ±0.5dB with
the low input sensitivity configuration.
The amplifier shall consume 1500 watts
of continuous power into 8Ωand 2400
watts into 4Ω. The unit shall be 3.5" (H)
x 19" (W) x 13.25" (D) (89 mm x 483 mm
x 337 mm). The net weight shall be
33 lb (15 kg).

The Model 1800-VI amplifier complies
with these agency regulations: UL6500
(ETL marking), CSA C22.2 No.1,
EN60065:1985, and EU emission and
immunity regulations for marking.
Regulatory Information
The Model 1800-VI is available with
optional Bose®circuit cards providing
active equalization for all Bose Profes-
sional Products loudspeaker systems.
Each channel has its own discrete circuit
card input slot. Therefore, a single ampli-
fier can drive one channel of 402®
loudspeakers and another channel of
502®loudspeakers, for example.
Active equalization plug-in circuit cards
provide proper equalization for all Bose
Professional Products loudspeakers
without use of a separate controller. A
Line Level EQ out is also provided to
connect additional 1800-VI amplifiers
without the need for extra EQ circuit cards .
