3. B1500 / B2000 Power Amplifiers

The B1500 or B2000 Amplifier is a no compromise, high quality, class AB power

amplifier.

Fan speed is varied as required to keep the amplifier within its temperature limits.

Signal limiters are included to protect speakers from clipped signals.

The amplifiers include full DC and short circuit protection on the outputs to ensure

trouble-free service in harsher environments.

The B1500 & B2000 amplifiers are a good power match for BOSE mid/high and bass

loudspeaker products, especially in foreground entertainment systems.

The B1500 amplifier is rated at 450 watts per channel 8 ohms and 715 watts per

Channel into 4 ohms and 1025 watts per channel into 2 ohms. In bridged mono

operation, it is rated at 1430 watts into 8 ohms and 2050 watts into 4 ohms.

The B2000 amplifier is rated at 560 watts per channel 8 ohms and 925 watts per

Channel into 4 ohms and 1300 watts per channel into 2 ohms. In bridged mono

operation, it is rated at 1850 watts into 8 ohms and 2600 watts into 4 ohms.

The inputs of each amplifier are high quality, electronically balanced and have high

common-mode rejection for exceptional hum and noise rejection. In addition, both the

B1500 and the B2000 amplifiers are equipped with internal connectors that enable the

use of BOSE Equalisation cards (EQ cards) one for each channel. This allows for

different equalisation for each channel if required (provided the correct equalisation

cards are installed). Equalisation cards are available for the entire range of BOSE

professional loudspeakers that require dedicated product equalisation.

A sample setup might involve one B1500 power amplifier driving two channels of

BOSE 802

III loudspeakers in stereo mode. A second Model B1500 power amplifier

in bridged mono mode could be added to drive a BOSE 502

B bass module.

Alternatively, just one amplifier could be used to drive the BOSE 802

III

loudspeakers on one channel and the BOSE 502

B module on the other channel.

Many configurations are possible. This flexibility can be achieved by installing the

EQ cards for the desired setup.
