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.

4.0 Installation  
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

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.  
5.3.4 Level controls  
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.

5.4.1 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.
