Description
PA720
Seven-channel Class-G power amplifier. Introducing the PA720, by Arcam.
Featuring the best-in-class components including a toroidal based power supply, an acoustically damped chassis, paralleled transistor output stages and exceptionally low levels of distortion, PA720 masters the reproduction of music with all its originality and detail for an unmatched level of sound quality and clarity.
Class-G amplifiers (which use rail-switching to decrease power consumption and increase efficiency) are more efficient than class-AB amplifiers. These amplifiers provide several power rails at different voltages, and switch between them as the signal output approaches each level.
Thus, the amplifier increases efficiency by reducing the wasted power at the output transistors. Class-G amplifiers are more efficient than class AB but less efficient when compared to class D, however, they do not have the electromagnetic interference effects of class D.
