High Definition Audio Technology with Quad Artera Stereo
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.
Quad 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 Quad's 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.
What is Current Dumping?
This compact yet potent power amplifier sports the latest iteration of Quad's famous Current Dumping topology, first introduced in the legendary Quad 405 - one of the most lauded British audio components of all time, and still the only amplifier design to have earned the Queen's Award for Technological Achievement.
Current Dumping is essentially a method of marrying the superior sonic purity of Class A amplification with the greater efficiency of class AB. An extremely high quality, low-power Class A amplifier provides the signal quality, while a high-power Current Dumping section delivers the muscle to keep the speakers under control.
These two amplifier circuits are then combined via a precision network to perfectly impose the finesse of the Class A output with the power of the currnet dumping section. Resulting in a relatively compact and cool- running power amplifier capable of delivering a captivating combination of dynamic power, vice-like grip, and sumptious sonic detail.
