2.0 Before You Begin
Thank you for purchasing a new Bose® commercial power amplifier. It is backed by stateof-the-art engineering and manufacturing techniques to bring you the best in quality
craftsmanship and reliable performance.
The instructions presented in this installer’s guide are written for professionals who are
familiar with the installation and operation of the equipment. If you are not, contact an
authorized Bose Professional Products dealer.
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
use it. Notify Bose Product Support or your authorized Bose Professional Products dealer.
2.2 The Bose Model 2150 commercial power amplifier
The Bose Model 2150 commercial power amplifier is specially designed for commercial
sound applications. Its rugged construction and low profile allow the amplifier to sustain
heavy use with reliability and space-saving economy. Accurate sound and ample power
make this amplifier ideal for critical listening applications.
The Model 2150 amplifier is rated at 150 watts per channel into 4Ω, 8Ω, 25V, 35V, 50V, 70V
or 100V. In bridged mono operation, it is rated at 300 watts.
Sophisticated protection circuits have been designed into the amplifier to protect your
system from unexpected faults. They also help protect the amplifier from excessive temperature, continuous current limiting, and shorted outputs.
The balanced inputs of the amplifier use a high quality, high common-mode rejection
differential amplifier for exceptional hum and noise rejection.
In addition, the Model 2150 amplifier is equipped with an input module to allow for separate
equalization of each channel (provided the correct equalization card is installed). Equalization cards (EQ cards) are available for all Bose professional loudspeakers requiring active
equalization.
A sample setup might involve one Model 2150 amplifier driving two channels of 402® loudspeakers in stereo mode. A second Model 2150 could be added to drive a 502B® module.
Alternatively, just one amplifier could be used to drive the 402 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.

3.0 Using The Amplifiers
3.1 Using the Bose Model 2150 commercial power
amplifier
®
English
Once you have installed and wired the amplifier, follow these tips to get the most from it:
• Verify that all switches (STEREO/MONO, CLIPPING LIMITER, 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).
• Write down the settings, either on paper or self-stick dots, and attach 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.
3.2 General precautions
Caution: 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 air can circulate freely behind, beside, and above the unit.
3.3 Mechanical considerations
The amplifier requires two 3.5" (8.9 mm) rack space units with a 16" (40.6 cm) inside depth
(including the rear supports). When mounting, use four screws with washers to prevent
marring the front panel. Neoprene rubber washers are a good choice because they grip the
screw head and prevent the screws from backing out from vibration or during transportation.
3.3.1 Rear support
Caution: 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 use brackets in such a way as to support the rear of the unit.

3.0 Using The Amplifiers
3.4 Thermal considerations
When the amplifier is used freestanding, no thermal considerations are necessary other
than keeping sufficient ventilation around the unit.
Bose® Model 2150 amplifiers may be stacked directly on top of each other without spacer
panels. If a Model 2150 amplifier is used with other amplifiers, be sure the heat output from
the amplifier does not interfere with the adequate ventilation of the others.
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 and a fan from the outside of the rack.
CAUTION: Do not allow the chassis to exceed the maximum operating temperature of
50˚ C. Be aware of conditions in an enclosed rack that may increase the temperature
above room ambient conditions.
3.5 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 the circuit can provide 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 during rock music reproduction, with both channels driven into 4 ohms until musical peaks are just below clipping. Under these conditions,
the Bose Model 2150 amplifier requires an average of 4.2 amps for 120V versions (2.2
amps for 220-240V versions).
3.6 Magnetic leakage considerations
You can mount the Model 2150 amplifier without concern for magnetic flux leakage.
However, it is not a good idea to mount any power amplifier near a microphone input
transformer or magnetic storage media.

Independent level controls are provided for Channel 1 and Channel 2. When each level
control is set fully clockwise the channel operates at maximum gain. Turning the controls
counterclockwise attenuates the output signal. Each level control adjusts incrementally in
steps of ±2.5dB.
The level knobs can be removed to prevent tampering with the amplifier volume. Once the
amplifier level is set, remove the knobs. Gently pull the knobs straight off and store them in
a safe place for future use. The controls can then be replaced with the supplied plastic
covers. See Figure 1 below.

Signal
The level indicators (see Figure 2) for each channel reflect the gain of each output stage. The
following LEDs light up when the signal reaches each respective threshold:
• CLIP – red light indicates the signal is clipping (0dB)
• -6dB – yellow light indicates the signal is at -6dB below clip
• -12dB – green light indicates the signal is at -12dB below clip
• -20dB – green light indicates the signal is at -20dB below clip
• SIGNAL – green light indicates the signal is at -40dB below clip
It is common to operate the amplifier so that the CLIP (red) LED illuminates at the loudest
point. If the CLIP LED remains on for an extended length of time or clipping is audible, then
the level should be reduced on the channel(s).

when conditions return to a safe operating temperature.
READY – A green light indicates that the amplifier is on.
4. Network activity indicator
In the future a network compatible input card will be available for the amplifiers. When this
card is installed, the network LED will flash yellow when the amplifier is receiving network
information.
5. Standby indicator
The LED illuminates yellow when the amplifier is set to STANDBY (standby).
6. Power switch
The power switch has three positions (ON/OFF/STANDBY). When on, the READY indicators
illuminate green. When off (middle position), no power reaches the unit and the sequencing
function is not active.
When set to STANDBY, the AC mains is connected to the standby circuit. The circuit awaits
a 12V DC current to be supplied to the amplifier. When the DC current is detected, a triac
allows the AC mains to be connected to the power supply, turning the amplifier on.
Note: Standby and Sequencing modes are activated at the amplifier only when using the
standard input module.
See Section 4.3.1 for additional information regarding the sequence feature.
7. Removable rack ears
Caution: If you shelf-mount the amplifier, the rack ears can be removed. Once removed, replace the screws that fastened the rack ears to the chassis. This will maintain the
structural integrity of the chassis.

Input Modules
1. Standard input module
Through the use of the Bose® input module (the standard module provided with the amplifier) and EQ cards, Bose Model 2150 amplifier can provide active equalization for Bose
Model 8, Model 32, Model 32SE, 402®, 502®A, 502B and 802® Series II professional loudspeakers.
Each channel of the input module has its own EQ card input connector, which allows
independent equalization for each channel. For a view of the input module, refer to Figure
31 on page 28.
2. Input connectors
A combination 1⁄4" TRS/XLR input connector on the input module allows for either a 1⁄4" TRS
(Tip-Ring-Sleeve) input or a XLR input. The input module quick-connect terminal block is
wired in parallel with the TRS/XLR input connector. This allows for easy connection of
stripped wires to the provided connector. Two parallel input connectors allow for simple
connection of parallel amplifiers. Only one connection per channel can be used.
Note: When using the standard input module in mono mode, use CH 2 input only.

3. 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 EQ cards,
see Input Modules on page 10.)
This is helpful if several devices are going to be driving similar Bose® loudspeakers (402®
loudspeakers, for example) with the same source signal. With EQ cards installed in the
Model 2150 amplifier, the EQ OUT (output) of the amplifier can be connected to the line
level inputs of additional devices driving the same type of Bose loudspeakers (e.g. 402
loudspeakers). Be sure to use EQ cards that correspond to the type of loudspeakers.
4. Equalizer present LEDs
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 2150 commercial
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 EQ cards are installed, the input module recognizes the cards and switches to
the equalizer circuitry. If no cards are installed, the input module bypasses the equalizer
circuitry and no LED will illuminate.

FX Loop in/out
Engages or bypasses the FX loop. ON (on) allows signals to pass through the FX loop. OFF
(off) closes the loop internally.
A four-pin barrier block connector is provided on each channel. The FX loop can be used to
send and receive unbalanced signals from outboard signal processing equipment such as
EQs, Delays, Limiters, etc. To activate the FX loop, set the dip switch to the ON position.
The send pins (+ and –) are always active and can be used to daisy chain the signal from
one amp to another amp via the receiving amplifier’s normal input. The return pins are
activated by the FX dip switch.
Clip limiter
Select between ON and OFF. When set to ON, the clip limiter will engage when the output
stage exceeds 0 dB, preventing output stage clipping. When set to OFF, there is no clip
limiter in the signal chain.
High-pass filter on/off
Selects whether the high-pass filter is ON or OFF. When set to ON, the high-pass filter will
default to the selection made on the 80Hz/120Hz dip switch. When set to OFF, there is no
high-pass filter in the the signal chain.
120Hz/80Hz (12dB/octave high-pass filter)
Selects the frequency for the high-pass filter. Selectable between 120Hz and 80Hz.

8. AC Power sequence connector
A three-pin Euro style terminal and mating connector are supplied with each amplifier to
allow the amplifier to be sequenced on or off remotely. This allows multiple amplifiers to be
powered on or off locally by using the first amplifier as the on/off master. These terminals
are located on the rear panel of the amplifier and are labeled SEQUENCE. The three terminals are from left to right and labeled ground, SND, and RCV (see Figure 6).
The sequence feature can be used to turn on or off one or more Bose® amplifiers. When
used with more than one amplifier the sequence feature will turn the amplifiers on or off
sequentially at about 0.5 second intervals. This will prevent a large turn-on surge through
the AC mains supply that could possibly cause disruption of the flow of current through the
AC mains.
Figure 6
SEQUENCE
Sequence connectors
SND RCV
Turning a single amplifier on or off:
Connect the positive side of a 12 to 15 VDC supply to the RCV terminal of the SEQUENCE
connector. Connect the ground side of the 12 to 15 VDC supply to the GROUND terminal of
the sequence connector.
The amplifier will remain on as long as the DC voltage is present. The amplifier will turn off
when the DC voltage is interrupted by opening the circuit at the SEQUENCE connectors. If
a switch is used to control the SEQUENCE circuit, it should be a SPST (single pole single
throw) type. A control device such as a contact closure contained within a system such as
Creston®, AMX® or Panja® can also be used to remotely control the power of the amplifier.
The contact closure must be a latching type and not a momentary contact closure.
Turning multiple amplifiers on or off:
Starting with the first amplifier in the sequence to be turned on, connect the positive 12 to
15 VDC to the RCV terminal. Next, connect a wire from the SND terminal of the first amplifier to the RCV terminal of the next amplifier to be turned on. Continue in this manner until
all amplifiers in the sequence are connected.
If the amplifiers are mounted together in a rack where the chassis grounds are connected
through common connection via the metal rack rail or by a common AC ground, no other
connections should be required (see Figure 7). If this is not the case, simply connect all of
the chassis ground terminals together (see Figure 8).

To remotely begin the sequencing function, close the circuit and supply the DC voltage to
the RCV receive pin on the first amplifier. The subsequent amplifiers should turn on at 0.5
second intervals.
Note: The front panel power switch should be in the STANDBY position on all of the
amplifiers in this group.
When the DC voltage is interrupted, the amplifiers will then turn off. If there are signal
processing and input source devices in the system, they should be turned on before the
amplifiers are sequenced on, and these same devices should be powered down after the
amplifiers are sequenced off. This will avoid large transient thumps being passed to the
loudspeakers attached to the system.
When using multiple amplifiers that utilize the SEQUENCE feature of the Bose® 2150, and
you would like to power them on, but remote operation is not required, you do not need the
DC Voltage to activate the SEQUENCE function. Simply connect the SND send terminal of
the first amplifier to the RCV receive terminal of the next amplifier and so on (see Figure 9).
The front panel power switch of the first amplifier will activate the SEQUENCE function
when switched to the ON position. All other front panel power switches should be in the
STANDBY position for the SEQUENCE function to operate properly. Again, if the amplifiers
are mounted together in a rack where the chassis grounds are connected together through
common connection via the metal rack rail or by a common AC ground, no other connections should be required. If this is not the case, simply connect all of the chassis ground
terminals together.

8. AC power sequence connector (cont.)
When mounting the amplifiers in a common rack, you should verify if the amplifiers’ chassis
are sharing a common ground via the rack rails. To do this use a Digital Multi-Meter DMM
to measure the DC resistance between the rack rail and the chassis ground of each unit. Set
the DMM to measure DC resistance. Connect one probe to the rack rail and the other to the
chassis ground terminal on the SEQUENCE terminal of the Bose® 2150. If the DC resistance is greater than 0.2 ohms we recommend that you connect the chassis ground terminals of the sequence connector together in a daisy chain as in Figure 8. Repeat this for
each Bose 2150 in the rack.
You do not have to daisy chain the chassis grounds together if there is less than a 0.2 ohm
resistance from the rail to the chassis ground of each unit. Let the rack rail be your chassis
ground path.
Using other amplifiers in the power sequence:
The Bose Models 1600 VI and 1800 VI can be used together with the Bose Model 2150 in a
sequenced configuration.
However, as the sequence terminal on the Bose® Model 1600 VI and 1800 VI has no chassis
ground connector, whenever this manual references the chassis ground connector, you
should replace it with some reliable ground connection point on the amplifier chassis, such
as a screw that is used in fastening the chassis parts together. A good example would be
the screws that retain the Bose input modules to the amplifier chassis. All other connections would be exactly as described in this discussion of sequencing hook-up procedures.
Note: For operation details regarding the Bose Model 1600 VI and the 1800 VI, please
consult the respective user guides provided with those amplifiers.

9. REMOTE LEVEL (remote level) control
Use a 1k to 10k potentiometer, preferably with a reverse log taper. Identify the terminal of
the pot to which the wiper is connected when the knob is set to the fully clockwise
position. Connect this terminal to the RTN (ground return) terminal of the REMOTE LEVEL
input plug.
Connect the center terminal of the pot to the CH1 (or CH2) control voltage terminal of the
REMOTE LEVEL input plug. The two channels are independently controlled by the voltages
applied to the CH1 and CH2 terminals. Both control inputs can be connected together and
driven off the wiper of one pot.
Connect the remaining terminal of the pot to the +5V terminal of the REMOTE LEVEL input
plug. This connection will set the control voltage to 0 with the knob fully clockwise (maximum level), 5V with the knob fully counterclockwise (minimum level).
Inside the amplifier, a 0V control voltage corresponds to 0dB added attenuation (that is,
added to the attenuation already set by the front panel level control for that channel). A 5V
control voltage corresponds to 100dB added attenuation. The control voltage effect is “dB
linear”: a 2.5V control voltage input will add 50dB of attenuation: the control characteristic
is -1dB per 50mV.
REMOTE LEVEL control wiring recommendations
For best results, use 24AWG (or larger) control wiring, especially for the +5V and RTN
connections. Since 24AWG wire has DC resistance of 25mW per foot, using 1000 feet of
24AWG (total loop resistance of 50W) to make connection to a 5kW potentiometer will
result in a 1% voltage drop. This will cause a reduction in the control voltage range. This
voltage drop increases as more current is carried by the +5V and RTN conductors; for
example, when the 5V line is used to light a remote LED indicating that the amp is ON.
In the example given above, an additional 10mA load on the +5V and RTN conductors will
cause 10% reduction in control voltage range, yielding lower maximum level and higher
minimum level. Within reason, conductor capacitance is not a problem since the control
voltages are averaged in the amplifier and any additional RC delay will not be noticeable.
Note: Do not connect the RTN conductor to a ground reference at the remote control
location. Ground potential differences will drive currents through the RTN line and cause
unpredictable REMOTE LEVEL control performance.

5.2 Input wiring
You can use 1⁄4" phone jacks, XLR connectors, or 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.
5.2.1 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 25).

5.3 Output wiring
The Model 2150 speaker outputs on the amplifiers can accommodate wire from 20 gauge
up to 12. We recommend that you do not use speaker wire smaller than 20 gauge. You must
use Class I (NEC) wiring.
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. A 14gauge wire is thicker than 18-gauge wire.
Using the following chart as a guide for low-impedence operation (4Ω, 8Ω):
Wire Length
Gauge of Wire
Up to 10'
20 gauge
10' to 15'
18 gauge
15' to 25'
16 gauge
25' to 40'
14 gauge
40' to 60'
12 gauge
Use the following as a guide for high-impedence operation (25V, 35V, 50V, 70V, 100V):
Wire Length
Gauge of Wire
Up to 250'
18 gauge
250' to 500'
16 gauge
Caution: 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.
5.3.1 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. It
is important that each speaker is connected to the amplifier as positive (+) to positive (+) and
negative (–) to negative (–).
5.3.2 STEREO/MONO and DUAL/MONO operation
The STEREO/MONO switch is located on the input board behind slot #2 of the standard
input module (see Figure 31). For dual-mono operation, move the STEREO/MONO switch
all the way to the left to the DUAL/MONO setting. 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.
Note: When changing settings, always disconnect the power cord.

5.3.3 Stereo/Mono switch
This switch selects between NORMAL STEREO (normal stereo), DUAL MONO (dual mono),
or BRIDGED MONO (bridged mono) operation. It is located on the motherboard of the input
module.
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.

5.0 Installation
The STEREO/MONO switch is located behind slot #2 of the standard input module (see
Figure 31). For bridged mono operation, move the STEREO/MONO switch all the way to the
right to the BRIDGED setting. Connect the input signal to CH 2 input (CH 1 input becomes
disabled).
Outputs:
Jumper the Commons (COM) on both CH 1 and CH 2. Next, connect the negative (–) to the
desired setting CH 1 output and positive (+) to the same setting on the CH 2 output.
When connected in this way, each channel “sees” half the impedance of the speaker
connected between them.
Note: Be sure to set both input level controls to exactly the same setting for equal power
distribution per channel.
In high-impedance bridged mono operation, the amplifier will yield the following results:

6.0 Troubleshooting
Troubleshooting
Problem
No sound, no power
(Usually indicates a
power supply problem,
either in the power line or
the amplifier’s power
supply.)
Power on, low output
or no output
(Usually signal-source,
bad cable or partial
output short circuit
related.)
Cause or Solution
•
•
•
•
•
•
•
•
Check amplifier. Power off, then 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.
No source playing.
Faulty connection between mixer and amplifier.
Open thermal breaker in the power transformer. Allow amplifier to cool
and the breaker will reset itself.
• Input level controls set too low. Reset.
• Check to see if problem is at the source. Move the input
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.
• Disconnect equipment in the FX loop to be sure that the equipment
is not faulty.
• Check remote volume control.
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
• 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.
(Usually caused by 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.)
Care
32
• 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.
• Speakers may be out of phase.
• 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.
