Bose®1800-VI professional stereo power amplifier

GENERAL DESCRIPTION
The Bose®Model 1800-VI professional stereo
power amplifier is a high performance
amplifier designed for use with all Bose
Professional Products loudspeaker systems.
The unit offers high power in a rugged, light-
weight (15 kg) package that is only two rack
space units (8,9 cm) 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 designed to accept
Active Equalisation plug-in circuit cards for
all Bose professional products loudspeakers,
eliminating 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 optionalACM-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 monitoring capability.
Using the graphical user interface of theACM-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 equalised line level out-
put to be connected to another device.
SYSTEM CONFIGURATION
Model 1800-VI amplifier detailed installation
and operating instructions are provided in
the
Model 1800-VI and 1600-VI professional
stereo power amplifier owner’s guide.
OPTIONAL EQUALISER CARD
INFORMATION
The Model 1800-VI is available with optional
Bose circuit cards providing active equalisation
for all Bose professional products loudspeaker
systems.
Each channel has its own discrete circuit
card input slot.Therefore, a single amplifier
can drive one channel of 402®loudspeakers
and another channel of 502®loudspeakers,
for example.
Active equalisation plug-in circuit cards
provide proper equalisation 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.

SPECIFICATIONS
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

with less than 0.2% distortion.
There shall be two parallel input connectors
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 connector.
The two output multi-way binding posts
shall be capable of accepting either spade-lug
or bare wire connections.There shall be two
1/4"TRS line level equalised signal outputs,
corresponding to the two channels.This
signal shall be accessed after the internal
equalisation 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.

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,unbalan-
ced, 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).
