Digital bass amp combo. Lightweight and extremely powerful thanks to the advanced neodymium magnet motor structure, exclusively a proprietary PJB transducer. A truly transparent yet powerful all digital amplifier, which embraces a digital switching power supply that operates on any AC voltage worldwide and a full bandwidth Pulse Width Modulation (PWM) high efficiency output stage. The result is an amplifier so efficient, it does not even require a weighty heat-sink that is often required in high power solid state amps.
