The Nordost QRT QBASE QB8 Mark III AC Distribution Unit provides eight outlets of pristine power conditioning for expanded system flexibility. Built on a focused star ground design with Primary Earth grounding, it delivers superior sonic performance while maintaining the lowest possible AC supply impedance. The absence of in-line filtering or active circuitry preserves signal integrity, while the optimized multi-level PCB architecture minimizes electromagnetic interference and maximizes current delivery. An external ground post enables custom grounding configurations for enhanced performance. Includes dedicated fuse protection with two replacement fuses provided.
