Please Note : Power Cables are not supplied with this block.
The essence of the QBASE-Mark II concept is a straight-line AC distribution path, combined with star-earthed topology for connection to a clean ground. By eliminating any form of in-line filtering or active circuitry we maintain the lowest possible AC supply impedance, while a tiny lift in the earth impedance of all but one of the output sockets routes the signal grounds directly to the center of the star and the clean earth terminal. Clearly identified on the casework, this Primary Earth socket is at the center of your system’s performance, literally and metaphorically. It defines both the order in which you connect your components and also, their listening priority in your musical enjoyment, allowing you to further optimize the performance of your primary sources.
The sockets themselves are mounted on a customized frame plate and solidly constructed aluminum extrusion with machined end-caps that deliver a reassuring sense of substance. But the casework has far greater significance than that, the metal pieces and internal PCB (deliberately preferred to hard-wiring) constituting a single, mechanically tuned construction, designed specifically to enhance performance. Compare the musical performance of the QBASE-Mark II to the competition and you’ll hear just how effective this is.
Each unit now includes a dedicated fuse, providing overcurrent protection of the source circuit to prevent overheating and system damage. A QBASE-Mark II unit is the perfect starting point in the construction of a high-quality, modular AC supply for your system. Its compact dimensions mean that it can be easily combined with one or more Qx power purifiers and outfitted with Qv2 AC Line Harmonizers and Qk1 AC Enhancers as funds allow, while its slim profile makes it ideal for tucking away behind a rack or mounting on the wall.

About Quantum Resonance Technologies
Mains distribution, grounding and network accessories for hi-fi, distributed worldwide by Nordost.
Quantum Resonance Technologies, often shortened to QRT, is distributed globally by Nordost.

The QBASE distributes mains power
The QBASE is a passive AC distribution unit with four to eight outlets. Nordost describes it as using star earth topology. It sits between the wall and your equipment, as a place to plug components in rather than an active conditioner.
Plug-in modules and grounding work alongside
The QRT plug-ins are the QSINE, QWAVE, QVIBE and QKOIL. Nordost says they reduce electromagnetic interference and the noise floor. The QKORE is a parallel grounding device, and the QPOINT is designed to align vibrations between nearby components. Check the product page for which modules suit your equipment.
A network switch and power supply extend the range
The QNET is a five-port Ethernet switch and the QSOURCE is a fanless linear power supply from 9V to 24V. These descriptions come from Nordost, so check the specification on the product page for the model you are buying. Check the supply's voltage against what your equipment needs.
