B2000 Power Amplifiers

The B

1500

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 B

1500

& B2000 amplifiers are a good power match for BOSE mid/hi

and bass

loudspeaker products, especially in foreground entertainment systems.

The B

1500

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

185

0 watts into 8 ohms and

00 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 ad

dition, both the

1500

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 B

OSE

professional

loudspeakers that require dedicated product equalisation.

A sample setup might involve one B

1500

power

amplifier driving two channels

BOSE

802

III loudspeakers in stereo mode. A second Model B

1500

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

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.
