2.0 Before Y ou 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 2060 and Model 2150 commercial
power amplifiers
The Bose Model 2060 and Model 2150 commercial power amplifiers are specially designed
for commercial sound applications. Their rugged construction and low profile allow each
amplifier to sustain heavy use with reliability and space-saving economy. Accurate sound
and ample power make these amplifiers ideal for critical listening applications.
The Model 2060 is rated at 60 watts per channel into 4Ω, 8Ω, 25V, 35V, 50V, 70V or 100V. In
bridged mono operation, it is rated at 120 watts.
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 each amplifier to protect your
system from unexpected faults. They also help 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 Model 2060 and the Model 2150 amplifiers are 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.

3.0 Using The Amplifiers
3.1 Using the Bose® Model 2060 or Model 2150
commercial power amplifier
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 contr ols 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:
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.
Place the unit where it will be protected from heat and allow adequate
3.3 Mechanical considerations
Either 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:
chanically 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.
If either unit is rack mounted and the rack is
transported
, you must me-

3.0 Using The Amplifiers
3.4 Thermal considerations
When either amplifier is used freestanding, no thermal considerations are necessary other
than keeping sufficient ventilation around the unit.
These amplifiers may be stacked directly on top of each other without spacer panels. If a
Bose® Model 2060 or 2150 amplifier is used with other amplifiers, be sure the heat output
from each 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:
50˚ C. Be aware of conditions in an enclosed rack that may increase the temperature
above room ambient conditions.
Do not allow the chassis to exceed the maximum operating temperature of
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 2060 amplifier requires an average of 3.4 amps for 120V versions (1.9
amps for 220-240V versions). 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 Bose Model 2060 or 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 ±2.5 dB.
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.

Level indicators
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).

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.

1. Standard input module
Through the use of the Bose® input module (the standard module provided with the amplifier) and EQ cards, Bose Model 2060 and Model 2150 amplifiers 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 2060 or 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 ar e 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.
