The B1200 or B2000 Amplifier is a no compromise, high quality, class AB power amplifier. There is no dynamic switching of the audio or power rails (a very common method of achieving extra power at the expense of audio quality) thus ensuring optimum sonic performance.

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 to ensure trouble-free service in ‘harsher’ environments.

The B1200 & B2000 amplifiers are a good power match for BOSE mid/high and bass loudspeaker products, especially in foreground entertainment systems.

The B1200 amplifier is rated at 375 watts per channel 8 ohms and 600 watts per Channel into 4 ohms and 920 watts per channel into 2 ohms. In bridged mono operation, it is rated at 1500 watts into 8 ohms and 2250 watts into 4 ohms.

The B2000 amplifier is rated at 610 watts per channel 8 ohms and 1000 watts per Channel into 4 ohms and 1500 watts per channel into 2 ohms. In bridged mono operation, it is rated at 2000 watts into 8 ohms and 3000 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 B1200 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 B1200 power amplifier driving two channels of BOSE 802® III loudspeakers in stereo mode. A second Model B1200 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.
