The QSOURCE Mark II is a new-generation linear power supply, engineered from the ground up to deliver a powerful, stable, and clean output of DC power while maintaining extremely low noise levels. Building on the proven foundation of the original QSOURCE, the MKII introduces a complete redesign that delivers 2.5 times the power to today’s high performance audio components, with even greater control and consistency.
The QSOURCE MKII employs dual high-performance transformers and a current-based circuit architecture designed to maintain exceptionally low noise levels throughout the power supply. Additionally, an internal QRT module minimizes unwanted resonances, while finned endcap heatsinks provide effective passive cooling without the need for a fan.
Back-loading input and output connections create a clean, streamlined look and simplify cable management, while Sort Kone compatibility beneath the mechanically tuned chassis allows easy integration of Nordost’s mechanical resonance-control solutions.
The QSOURCE MKII features four 5V outputs, designated for QPOINT Resonance Synchronizers, and two selectable DC outputs that supply 9 or 12 VDC, or 12, 19 or 24 VDC, respectively. These variable voltage outputs match the requirements of a wide range of DC-powered components, including the QNET and QNET7 network switches, music servers, routers, and NAS drives.
The result is a cleaner, more powerful foundation for components that run on DC, enabling connected components to perform at their best and revealing greater clarity, dynamics, and musical nuance in every performance.
