Best Marantz 5 Channel Amplifiers

View larger Full Range, Class A/B Topology A class A/B amplifier uses two groups of transistors and it is generally considered to be the best compromise of the two classes - A and 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. A class A/B amplifier is much more efficient than a class A, but without the possible distortion of a class B. MOSFET Power Supply A Metal–Oxide–Semiconductor Field-Effect Transistor is a transistor used for amplifying or switching electronic signals, found in systems where information is processed or stored. We use them in our computers, telephones, game consoles, cars, electrical appliances, and, in this case, amplifiers. A MOSFET is basically an electrical switch with two possible states - on or off - that allows the flow of electrical current. 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.

The “4” channel means that you are able to simply use the NX2000.4 as a four channel amplifier by hooking up four speakers - fronts and rears - to it. The “3” channel allows you to hook up two speakers to channels 1 and 2 and use the remaining 3 and 4 channels for one subwoofer in bridged mode. Channels 1 and 2 can be bridged to accommodate one speaker or one subwoofer. Channels 3 and 4 can be used in the exact same application.
