CLASS D is 80% efficient. Switching output stages reduces unwanted heat dissipation and power input, therefore smaller batteries will be required for standby. Rated output power is attainable using a 22V battery supply.
The amplifier has a sleep mode, automatically reducing the standby requirements to 50mA per amplifier when operating on batteries.
220Watt versions can be paralleled to produce higher single output powers.
Up to three BV220 Amplifier modules may be mounted in one BVMF equipment frame or two amplifier modules and one switched mode power supply / charger module.
The BV220 Module is equipped with two 500mV balanced line inputs incorporating a priority switching system. The priority is selected using a 4-way DIL switch.
