2.0 Before You Begin
Congratulations on your purchase of a new Bose® Professional Stereo Power Amplifier. It is
backed by state-of-the-art engineering and manufacturing techniques to bring you the
best in quality craftsmanship and reliable performance.
2.1 Unpacking the amplifier
Carefully unpack your amplifier. Keep the original carton and packing materials for possible
future use. Check for any visible signs of damage. If the amplifier appears damaged, do not
try to use it. Notify the Bose Product Support or your authorized Bose Professional Prod-
ucts dealer.
3.0 The Bose Model 1800-VI and 1600-VI
Professional Stereo Power Amplifiers
The Bose Model 1800-VI and 1600-VI Professional Stereo Power Amplifiers are specially
designed for professional sound applications. Their rugged construction and low profile
allow each amplifier to sustain the abuses of the road with reliability and space-saving
economy. Also, their accurate sound and ample power make these amplifiers ideal for
critical studio applications.
The 1800-VI amplifier is rated at 600 watts per channel into 4 ohms and 450 watts per
channel into 8 ohms. In bridged mono operation, it is rated at 1400 watts into 8 ohms.
The 1600-VI amplifier is rated at 325 watts per channel into 4 ohms and 240 watts per
channel into 8 ohms. In bridged mono operation, it is rated at 700 watts into 8 ohms.
The sophisticated protection circuits designed into each amplifier will protect your system
from unexpected faults. They also protect each amplifier from excessive temperature,
continuous current limiting, and shorted outputs.
The balanced inputs of each amplifier use a high quality, high common-mode rejection
differential amplifier for exceptional hum and noise rejection.
In addition, both the 1800-VI and the 1600-VI amplifiers are equipped with an input board
that allows different equalization for each channel (provided the correct equalization card
is installed). Equalization cards (EQ cards) are available for Bose 402®, 502®A, 502B, and
802® loudspeakers.
A sample setup might involve one Model 1800-VI amplifier driving two channels of 802
loudspeakers in stereo mode. A second Model 1800-VI could be added to drive a 502B
module. Alternatively, just one amplifier could be used to drive the 802 loudspeakers on one
channel and the 502B module on the other channel. Many configurations are possible using
the four loudspeakers above. This flexibility can be achieved by installing the EQ cards for
the desired setup.

4.0 Installation
4.1 Location and general precautions
Locate the unit where it will not be exposed to rain or moisture. If fluid or a foreign object
enters the unit, disconnect the power plug. Do not pull by the cord; grasp the plug firmly.
Contact an authorized dealer or service center.
Place the unit where it will be protected from heat and allow adequate ventilation. Place it
away from direct heat sources, such as heating vents and radiators. Make sure the ventila-
tion holes are not covered and air can circulate freely behind, beside, and above the unit.
4.2 Mechanical considerations
Either amplifier requires two 3.5" rack space units with a 15" depth inside the rack (including
the rear supports). Use four screws with washers to prevent marring the front panel. Neo-
prene rubber washers are a good choice because they grip the screw head and prevent the
screws from backing out in the event of vibration or if the unit is transported.
4.2.1 Rear support for road applications
If either unit is rack-mounted and the rack is transported, you must mechanically support
the rear of the amplifier. You can place a shelf across the rear of the amplifier or brackets
in such a way as to support the rear of the unit. This practice is recommended for all
electronic instruments.
4.3 Thermal considerations
When either amplifier is used free-standing, no thermal considerations are necessary other
than keeping the ventilation holes open.
If the unit is rack-mounted, allow for adequate ventilation exits in front of and behind the
amplifier. When several amplifiers are mounted together in a rack, you may need to provide
air inlets from the outside of the rack.
The unit is fan cooled. The fan is internally mounted so that it draws air in from the front and
exhausts it out the rear. This allows cool air from outside the amplifier to flow over and cool
the power supply components located in front of the heatsinks.
These amplifiers may be stacked directly on top of each other without spacer panels. If an
amplifier is used with other amplifiers, be sure the heat output from each amplifier does not
interfere with the ventilation of the others.
4.4 AC power considerations
Be sure to plug your amplifier into an outlet capable of supplying the correct voltage
specified for your model. Check to be sure there is enough current to allow full-power
operation of all the amplifiers in your system.
The power plug serves as the Main Disconnect device and should always be easily
accessible after installation.
The current demand of a power amplifier varies depending on the impedance of the load,
the output level of the amplifier, and the crest factor and duty cycle of the program material.
For example, consider typical conditions reproducing rock music, with both channels driven
into 4 ohms to the point where musical peaks are just at the clipping point.
Under these conditions, the Bose® Model 1800-VI amplifier requires an average of 6.7 amps
for 120V versions (3.5 amps for 230V versions).
The Bose Model 1600-VI amplifier requires an average of 4.2 amps for 120V versions (2.2
amps for 230V versions).
4.5 Magnetic leakage considerations
You can mount the Bose Model 1800-VI or 1600-VI amplifier without concern for magnetic
flux leakage. However, it is not a good idea to mount any power amplifier near a micro-
phone input transformer or magnetic storage media.

4.6 Input wiring
You may use 1/4" phone jacks, XLR connectors, and quick connect terminal block
connectors for the input signal with either unbalanced 2-conductor or balanced
3-conductor cables. Use shielded coaxial cable to conduct the signal from the
source (mixer, equalizer, CD player) to the amplifier.
4.6.1 Balanced operation
For the 1/4" phone jack, use a 3-conductor TRS 1/4" phone plug. The tip of the plug
carries the + (hot, non-inverting) side of the signal. The ring carries the – (low, inverting)
side of the signal. The sleeve is ground (see Figure 1).
Figure 1
1/4" phone jack balanced input
connection.
For the XLR, use a male XLR connector. Pin 2 carries the + (hot, non-inverting) side of the
signal. Pin 3 carries the – (low, inverting) side of the signal. Pin 1 is ground (see Figure 2).
Figure 2

4.0 Installation
For the quick connect terminal block, use the female connector provided. Pin 3 carries
the + (hot, non-inverting) side of the signal. Pin 2 carries the – (low, inverting) side of the
signal. Pin 1 is ground (see Figure 3).
Figure 3
Quick connect terminal block
balanced input connection.
If you are using the standard input module for either amplifier, the polarity of the balanced
inputs can be reversed by changing four jumpers located on the input board, just behind the
input connectors. If you are using the ACM-1 module for either amplifier, the polarity cannot
be reversed. Refer to page 12 for a description of the different modules.
4.6.2 Unbalanced operation
For the 1/4" phone jack, use a 2-conductor (tip-sleeve) 1/4" phone plug. The tip of the plug
carries the signal and the sleeve is ground. The ring connection in the jack is automatically
grounded by the sleeve (see Figure 4).

4.0 Installation
For the XLR, pin 2 carries the + (hot, non-inverting) side of the signal, and pin 1 is
ground. To reference the input differential amplifier for the correct gain, short pin 3
to pin 1 (see Figure 5).
Figure 5
1/4" XLR unbalanced input
connection.
For the quick connect terminal block, pin 3 carries the + (hot, non-inverting) side of the
signal, and pin 1 is ground. Short pin 2 to pin 1 in order to reference the input differential
amplifier for the correct gain (see Figure 6).

4.7 Input sensitivity
The amplifier input sensitivity is set to 0.775V rms for rated output. To reduce the sensitivity
by 6 dB to 1.5V rms, simply remove JP100(CH1) and JP200(CH2), located on the main
amplifier board (see Figure 7).

4.0 Installation
4.8 Output wiring
Use heavy gauge wire for speaker connections. The greater the distance between the
amplifier and the speakers, the larger the diameter the wire should be. This will minimize
power losses across the wire and improve damping of the speaker. Wire thickness
specifications (gauges) get larger as the wire gets thinner. So a 14-gauge wire is thicker
than 18-gauge wire. Use the following chart as a guide.
Wire Length
Up to 15'
Gauge of Wire
18 gauge
16 gauge
14 gauge
12 gauge
10 gauge
8 gauge
15' to 25'
25' to 40'
40' to 60'
60' to 100'
100' to 150'
150' to 250'
6 gauge
This will keep the resistance of the speaker wire to less than 5% of 4 ohms and the
transmission loss to less than 0.5 dB.
The multi-way binding posts can accept spade lug, bare wire, or banana connections. Be
sure all the fine strands of the wire are twisted together and contained within the connector.
If even one strand is loose and can touch the adjacent terminal, a short circuit may result.
You must use Class I (NEC) wiring.
4.8.1 Polarity
In order to have correct phasing between loudspeakers, you must connect them with consistent
polarity. While incorrect phasing will do no physical harm, it will diminish your bass response.
The key is to make sure both speakers are connected to the speaker terminals the same way.
Connect – at the speaker outputs to – on the back of the speaker, and + at the speaker
outputs to + on the back of the speaker.
4.8.2 Dual mono
The stereo/mono switch is located on the input board behind slot #2 of the standard input
module (or, on the AMC-1 module, to the left along the rear edge of the board). For dual-
mono operation, move the STEREO/MONO switch all the way to the left to the DUAL
setting (or, on the AMC-1 module, move that switch all the way to the right). Connect the
input signal to CH 2 input (CH 1 input becomes disabled). Connect the speakers to the
speaker outputs on the amplifier just as for normal stereo operation. Both speaker outputs
will carry the signal connected to the CH 2 input.

The stereo/mono switch is located on the input board behind slot #2 of the standard input
module (or, on the AMC-1 module, to the left along the rear edge of the board). For bridged-
mono operation, move the STEREO/MONO switch all the way to the right to the BRIDGED
setting (or, on the AMC-1 module, move that switch all the way to the left). Connect the
input signal to CH 2 input (CH 1 input becomes disabled). Connect the speakers to the two
+ speaker terminals. The CH 2 + terminal is the hot (non-inverting) side, and the CH 1 +
terminal is the low (–, inverting) side (see Figure 8).
CAUTION
In bridged mono operation,
the output connections are
actually a balanced output
configuration. This means
both output terminals have
voltage present (neither may
be grounded).
When connected in this way, each channel “sees” half the impedance of the speaker
connected between them. If you use an 8 ohm speaker, each channel will see a 4 ohm load.
Therefore it is not recommended that you use any load lower than 8 ohms in this mode of
operation. Use parallel mono operation for lower impedances.
Note
Be sure to set both of the input level controls to the exact same setting for equal power
distribution per channel. Switching the level defeat switch (located on the amplifier) to OFF
will assure that both channels are operating at the same level.
4.8.4 Parallel mono
Parallel mono operation is useful when running sustained high levels in a single load or
when driving a low impedance load.
For instructions, contact Bose® or your authorized Bose Professional Products dealer.
4.9 Clipping eliminator
This circuit prevents the input signal from exceeding the point where it would drive the
amplifier into hard clipping. It has no effect until the signal reaches the clipping point. The
larger the input signal, the more it is reduced to keep the output just below clipping.
The clipping eliminator circuit is operational at the point of manufacture. However, you can
defeat it by using the clipping eliminator defeat switch. This switch is located on the rear
panel of the amplifier. Moving the switch up will re-engage the clipping eliminator.
Note
If you turn the input level down far enough, a sufficiently large input signal can drive the input
differential amplifier into clipping. The clipping eliminator circuit cannot remedy this. It also has
no effect on clipping that occurs prior to the amplifier inputs, such as at the mixer or equalizer.

5.0 Operation
®
5.1 Using the Bose Model 1800-VI or 1600-VI Professional
Stereo Power Amplifier
Once you have installed and wired the amplifier, follow these tips to get the most from it.
Verify all switches (stereo/mono, clipping eliminator, EQ Bi-Amp/Full Range and level
defeat) are set to the mode you want.
Turn down the amplifier controls when you power up the system for the first time. Then
advance them slowly, one at a time, to verify that each channel is operating correctly.
Set input level controls high enough to allow the preceding device to drive the amplifier
to full output. Usually, this is wide open (fully clockwise).
Mark down the settings, either on paper or self-stick dots attached to the front of the
amplifier.
In bi-amplified (multi-amp) systems, start with the low frequency amps turned down or
off. Check each frequency range from highest to lowest to make sure each loudspeaker
component is operating correctly.
5.2 Input Modules
5.2.1 Standard input module
Through the use of Bose input module (the standard module provided with the amplifier)
and equalization cards, Bose Model 1800-VI or 1600-VI amplifiers can provide active
equalization for Bose 402®, 502®A, 502B, and 802® professional loudspeakers.
Each channel of the input module has its own equalizer card input connector, which allows
different equalization for each channel (provided the correct EQ card is installed). For a view
of the input module, refer to Figure 10 on page 16.
A sample set up might involve one Model 1800-VI amplifier driving two channels of 502A
loudspeakers in stereo mode. A second Model 1800-VI amplifier could be added to drive a
502B module. Alternatively, just one amplifier could be used to drive the 502A loudspeakers
on one channel and the 502B module on the other channel. Many configurations are
possible using the four loudspeakers above. This flexibility can be achieved by installing
the EQ cards for the desired setup. For a view of the ACM-1 module, refer to Figure 11
on page 16.
5.2.2 ACM-1 amplifier control module
The Bose ACM-1 amplifier control module is designed to establish network control of the
Bose 1800-VI or 1600-VI amplifier. This network link makes remote operation of signal level
and power on/off functions possible. The module also provides amplifier monitoring capa-
bility. Using the graphical user interface of the ACM-1 module software, settings like
amplifier output, amplifier load, temperature, and clip levels can be checked routinely. Refer
to the ACM-1 installer’s guide for complete installation instructions.

5.0 Operation
5.3.1 Power switch
The power switch is used as a functional switch and should not be relied upon as a
safety disconnect.
100 volt and 120 volt versions: Press to turn the power ON or on STANDBY. When ON, the
READY indicators will illuminate. In the STANDBY mode, the unit is off but can be activated
through the SEQUENCE connector on the rear panel of the amplifier. Be sure all connections
are made and double checked before switching the power amplifier ON.
Note
Standby (see above) and Sequencing (see below) modes are activated at the amplifier only
when using the standard input module. For the ACM-1 module, these modes are estab-
lished via the network. For further detail, refer to instructions included with the network.
220-240 volt version: This version has separate POWER and SEQUENCE switches on the
front panel. Press the POWER switch to turn power on (1) or off (0). When the unit is off, no
power reaches the unit and the sequencing function is not active. To use the amplifier in
the normal mode, set the POWER switch on and set the SEQUENCE switch to the off
position ( ). The READY indicators will illuminate. To activate the sequencing function, the
SEQUENCE switch must first be switched to the on position ( ) and then the POWER
switch must be turned on. The unit will then be in a standby mode and can be activated by the
sequence signal. See Section 5.4.8 for additional information regarding the sequence feature.
5.3.2 Standby LED
Illuminates when the power switch is turned OFF to indicate the amplifier is connected to
AC power and the amplifier can be powered up. When the power switch is ON, the standby
LED turns off.
CAUTION
5.3.3 AC power fuse
Always replace with the same
type and value fuse indicated
next to the fuse holder.
Protects the amplifier from catastrophic failures that could damage internal circuitry.
Repeated fuse blowing is a sign of internal distress. Refer to an authorized Bose® Service
Center for evaluation.

Used to adjust the input level of each channel. When fully clockwise, the amplifier operates
at maximum gain. Turning the controls counter-clockwise attenuates the input signal.
You can bypass the Level controls internally to lock the amplifier at its full gain capacity.
See the Note about the level defeat switch on page 13.
5.3.5 Status indicators
The ON LED illuminates green when the power is on and the amplifier is ready to operate.
The ON LED illuminates red when the power switch is first turned on (while the power
supply is stabilizing prior to the speaker output relays switching in) or when the amplifier is
in protect mode.
The five SIGNAL LEDs illuminate yellow when a signal is present at the speaker output jacks
to indicate output power relative to full power (0 dB).
The PEAK/PROTECT LED illuminates red when the power switch is first turned on, when the
output begins to clip, or whenever there is a fault condition that causes the output relays to
disengage. These fault conditions include excessive DC offset, excessive heatsink tempera-
ture, and short circuits at the speaker outputs.
Note
The relays operate independently for each channel. Therefore, it is possible for one channel
to operate normally while the other is in protect mode.
5.3.6 Data receive indicator
Flashes a yellow light when an installed ACM-1 module is receiving network information.

5.0 Operation
5.4 Rear panel (see Figures 10 & 11)
5.4.1 Stereo/mono switch
Located on the motherboard of the input module, this switch selects between NORMAL
STEREO, DUAL MONO, or BRIDGED MONO operation.
For NORMAL STEREO operation, use CH 1 and CH 2 inputs. For DUAL MONO or BRIDGED
MONO operation, use CH 2 input only. See the section on bridged operation for more information.
5.4.2 Clipping eliminator switch
You can bypass the clipping eliminator circuit with this switch (located just to the right of
the input panel). Turning the switch OFF deactivates the clipping eliminator and allows the
amplifier to clip when driven beyond its maximum output capability. The clipping eliminator
is operational at the point of manufacture (switch in the up position). For more information
on how the clipping eliminator circuitry works, see Section 4.9.
5.4.3 Input connectors
There are two input connectors per channel which enable three different types of input
connectors to be used. A combination 1/4" TRS (Tip-Ring-Sleeve)/XLR input connector on
the input module allows for either a 1/4" TRS input or a XLR input. A quick connect terminal
block input is also on the input module and is wired in parallel with the TRS/XLR input
connector. This allows for easy connection of stripped wires to a connector which is
provided. Two parallel input connectors allow for simple connection of parallel amplifiers.
Note
When in mono mode, use CH 2 input only.

5.0 Operation
5.4.4 EQ OUT connectors
A 1/4" TRS output connector provides access to an equalized line level output signal for
each channel. If equalizer cards are installed, this signal has passed through the internal
equalizer, but has not passed through the amplifier itself. (For additional information on
equalization cards, see Input Modules on page 14.)
This is helpful if several devices are going to be driving similar Bose® loudspeakers (802®
loudspeakers, for example) with the same source signal. With equalization cards installed in
the Model 1800-VI or 1600-VI amplifier, the EQ OUT of the amplifier can be connected to
the line level inputs of additional devices driving the same type Bose loudspeakers (i.e. 802).
The type of equalizer cards used must correspond to the type of loudspeakers.
5.4.5 Equalizer LEDs
You can install equalizer cards on the motherboard of the input module by removing the
input module. When you install an equalizer card, the corresponding LED illuminates to
indicate the presence of the card.
Each channel can utilize a different card. For example, the Bose Model 1800-VI Professional
Stereo Power Amplifier can have both a 402® and a 502®B equalizer card installed. When
you install a 502B card in either card position, it automatically selects the high frequency
output of the other card. When a system uses two or more amplifiers, and you are using a
502B module, use the EQ Bi-Amp/Full Range switch to run in the bi-amp mode.
Note
When equalizer cards are installed, the input module automatically senses the cards and
switches to the equalizer circuitry. If no cards are installed, the input module bypasses the
equalizer circuitry.
5.4.6 EQ Bi-Amp/Full Range switch
This switch is located on the motherboard of the input module. The module must be
removed to access this switch. To select the high frequency output from both equalizer
cards, engage this switch (HF ONLY position). The high pass filter begins reducing the
signal below 140 Hz and allows the same equalizer card to be used for full range output
and bi-amp output. This feature is useful when using two or more amplifiers and a 502B
module.
5.4.7 Level defeat switch
This switch is located above the input module and defeats the CHANNEL 1 and CHANNEL 2
LEVEL controls. When the controls are defeated (switch moved to the left) the amplifier gain
is set at the maximum level. The module must be removed to access this switch.
5.4.8 Sequencer connector
This feature is helpful if you are using many amplifiers since it allows amplifiers to sequen-
tially power up. This reduces the initial surge currents from the AC power source to avoid
tripping circuit breakers. The SEND connector of one amplifier is connected to the RECEIVE
connector of the next amplifier. Turn the master power off by switching the equipment rack,
circuit breaker or other main power switch off. The first amplifier in the chain should be in
the normal on position. The subsequent amplifiers should be in the standby mode. When
the master power is turned on, the amplifiers will sequentially power up. For additional
information on switch settings, see Section 5.3.1.

5.0 Operation
5.4.9 Speaker outputs
Multi-way binding posts connect the loudspeakers to the amplifier outputs. The red
terminals are the signal connection (+) and the black terminals are the signal return
connection (–). The black terminals are internally tied together and to signal ground.
See Section 4.8 for additional output wiring information.
Note
Only connect the Bose® model loudspeaker corresponding to the EQ card installed in
the input module. Use of a different loudspeaker may result in permanent damage to
the loudspeakers.
5.4.10 Power cord
Connect to a properly configured outlet providing the line voltage specified for your model.

6.0 Troubleshooting
Problems/solutions
If you are having trouble or suspect a problem with the Bose® Model 1800-VI or 1600-VI
Professional Stereo Power Amplifier, try some simple troubleshooting before contacting an
authorized Bose Service Center.
Problem
What to do
No sound, no power
• Amplifier power off. Turn on.
• Linecord disconnected.
• Poor fit between the plug and AC receptacle. Try another receptacle.
• Power off at AC receptacle. Check with tester or lamp.
• Blown amplifier fuse. Replace fuse.
(Usually an indication of a
power supply problem,
either in the power line
itself or the amplifier’s
power supply.)
• Open thermal breaker in the power transformer. Allow amplifier to
cool and the breaker will reset itself.
Power on, low output • Input level controls set too low. Reset.
or no output
• Check to see if problem is at the source. Move the input
(Usually signal-source,
bad cable or partial
output short circuit
related.)
connections to another amplifier you know is working.
• Be sure that there are no small strands of wire touching similar
strands coming from the other wire in the cable.
• Make sure the speakers are functioning correctly.
• If you are using bridged-mono mode, make sure the stereo/mono
switch is set correctly.
• Use a voltmeter to determine if the power line voltage is dropping
excessively when the amplifier is driven hard.
Playback mixed
with hum
• Check or replace the connecting cables.
• Make sure that each screw terminal connection is tight.
• Signal cables may have been routed too closely to AC cables,
power transformers, motors or other EMI inducing device.
• Connect another source to the power amplifier inputs. If the hum
stops, the problem lies with the original source component.
Distortion
(Usually caused by
• Check input level controls. If set too low, the preceding piece of
equipment may not have sufficient output to overcome the loss.
• Check speaker connections and verify that all screw connections
are tight and that there are no stray strands of wire to cause
short circuits.
• Verify that the total load impedance presented to the amplifier
is within the limits described in this manual for the mode of
operation selected.
excessive loss in the input
controls when the mixer/
equalizer/crossover does
not produce enough
output. Also caused by
over-driving that results in
output clipping, or current
limiting caused by
excessively low load
impedances.)
Unnatural sound
(Some parts of the
frequency band do not
sound balanced with the
rest of the band.)
• Check the EQ cards. Verify that the EQ card corresponds to the
model speaker being used and that the EQ card is installed in the
proper channel. Verify that the speakers are connected to the
same channel that the corresponding EQ card is installed in.
Care
• Wipe the front panel and chassis with a soft, dry cloth.
• For stubborn spots, use a mild dish soap or detergent sparingly
applied to a soft cloth.
• Don’t use alcohol, ammonia, or other strong solvents.
