2.0 Before You Begin
®
Thank you for purchasing a new Bose
commercial 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.
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.
A sample setup might involve one Model 2150 amplifier driving two channels of 402
loud-
®
speakers 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.
