Key to the Artera Mono’s design is QUAD’s patented current dumping technology developed the QUAD’s legendary founder Peter Walker. In the Artera Mono’s current dumping circuit, a very high-quality Class AB low-power amp provides the details of the signal, while a high-power current dumping section provides the grip to keep the speakers under control. This technology eliminates the problems of crossover distortion, thermal tracking and transistor matching. Consequently, there are no internal adjustments or alignments and the choice of power transistor types is less restrictive.

In high contrast to OCC, the materials traditionally used in audio electronics is classed as OFC (Oxygen Free Copper). As impressive as OFC can be, by nature still has a multitude of grain boundaries and other impurities. OFC has around 400 crystals per foot and despite its name, OFC typically has an oxygen content of about 10 ppm. Thus, the Artera Mono OCC design ensures the purest of output signal offerings.

Delivering 300 watts per channel (into 8 ohms) the QUAD Artera Mono is equipped to drive the most demanding of systems. It offers instant overload recovery and full protection against over-driving without resorting to output line fuses or relays. It has the power to grip almost any speaker with relative ease – but they do it in a confident, almost understanding way instead of attempting to impress with sheer brute force.
