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 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 4 , 8 , 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 tem-

perature, 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). Equaliza-

tion 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.
