From the transformer to the input terminals, each section of the Artera has been engineered from the ground up to ensure power, musicality and stability. The Artera Stereo produces 140 Watts RMS per channel – ample power for driving first-class loudspeakers, unfaltering even under high dynamic and transient conditions thanks to the patented Current Dumping technology. Special attention has also been paid to the newly developed balanced XLR inputs. The robust connections are yet another string to the Artera Stereo's bow, with an incomparable signal to noise ratio.

Creating an experience for the modern living room has been the primary focus of Artera Series. However, it wouldn't be QUAD without referencing a heritage of manufacturing audio equipment since 1936. The famous QUAD 405, although not QUAD’s first solid-state amplifier, was a game-changer and the first to demonstrate the patented 'current dumping' technology, which is also the basis of the fully updated drive technology of Artera Stereo. The technology results in an amplifier with Class A sound quality and yet with a huge and fully stable power output.

Artera Stereo incorporates QUAD's patented current dumping technology developed by QUAD's founder Peter Walker. One of the few truly innovative amplifier topologies, it is essentially a combination of two amplifiers that give the best of both Class A and Class B operation. The current dumping circuit consists of a very high quality class A low-power amp which provides the finesse of the music signal, while a high-power current dumping section provides the grip to keep the speakers under control. These two amplifier circuits are combined via a precision bridgenetwork to perfectly impose the clarity and musicality of the class A output onto the power of the current dumper.
