GENERAL DESCRIPTION
The Bose®Model 1600-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, lightweight (13,6 kg)
package that is only two rack space units
(8,9 cm) high.The amplifier is suitable for
portable or permanent installations.
The 1600-VI amplifier is a high powered,
two channel amplifier delivering 240 watts
per channel into 8Ω,325 watts per channel
into 4Ω,or 700 watts bridged into 8Ω.
The 1600-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 1600-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 monitoring capability.
Using the graphical user interface of the
ACM-1 module software, settings like ampli-
fier output, output load, and temperature
can be checked routinely.
The Model 1600-VI amplifier accepts both
balanced and unbalanced inputs fromTRS,
XLR or stripped wire connections.The rear
panel allows for an unused parallel input or
the actively equalised line level output to be
connected to another device.
SYSTEM CONFIGURATION
Model 1600-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 1600-VI is available with optional
Bose®circuit cards providing active equali-
sation 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
1600-VI amplifiers without the need for
extra EQ circuit cards.
ENGINEERS’ AND ARCHITECTS’
SPECIFICATIONS
The Model 1600-VI amplifier shall deliver
240 watts of continuous power, both channels
driven, into 8Ωwith less than 0.2% distortion
from 20Hz to 20kHz.The amplifier shall
deliver 325 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 700 watts of continuous power
into 8Ωwith 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 2.0dB.
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,un-
balanced, each leg to ground and 50kΩ
balanced.The high sensitivity shall be 0.775
volts rms for rated power into 4Ω@ 1kHz,
and 43mV rms for 1 watt into 4Ω@ 1kHz.
The low sensitivity shall be 1.5 volts rms for
rated power into 4Ω@ 1kHz and 83mV rms
for 1 watt into 4Ω@ 1kHz.
The gain shall be 33.3dB, ±0.5dB with the
high input sensitivity configuration.The gain
shall be 27.6dB, ±0.5dB with the low input
sensitivity configuration.
The amplifier shall consume 1000 watts of
continuous power into 8Ωand 1550 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 30 lb (13.6 kg).
