BOSS Audio CXXM2200 Chaos Exxtreme II 2200-watts Monoblock Class A/B 1 Channel 2-8 Ohm Stable Amplifier with Remote Subwoofer Level Control

A class A/B amplifier uses two groups of transistors and it is generally considered to be the best compromise of the class 'A' and class 'B' put together. A pure class €˜A€ amplifier typically has an enormous amount of current flowing through its output transistors with no audio signal. A pure class €˜B€ amplifier has no current flowing through its outputs with no audio signal. This eliminates virtually all of the crossover distortion that€s possible with class €˜B€ amplifiers. A class A/B amplifier is much more efficient than a class €˜A€ but without the possible distortion of a class €˜B€.

Metal€“Oxide€“Semiconductor Field-Effect Transistor is a transistor used for amplifying or switching electronic signals. We use it in our computers, our telephones, game consoles, cars, electrical appliances, and in this case, our Amplifiers. They are found in systems where information is processed or stored. A MOSFET is basically an electrical switch that allows the flow of electrical current. An electrical switch has two possible states, ON or OFF. This is where the MOSFET performs its most important role in our D Class amplifiers by allowing or preventing the flow of power and creating an efficient amplifier.
