QRT AC Power Distribution Unit
Thank you for purchasing a QRT AC power distribution unit. You have just taken a very important step in improving the sound and picture quality of your audio/video system. Please read this manual carefully as the optimum wiring topology will vary with each system, according to the guidelines laid out below. It is important to follow these in order to achieve maximum sonic results.
PHILOSOPHY
The QRT Qbase AC power distribution units are specifically designed to deliver
an optimized, star-earthed, low-Impedance AC supply for any high-quality audio
or video system. They do not rely on active circuitry but instead employ
superior materials, a tuned mechanical structure and QRT’s Focussed Earth
technique to provide superior performance, not by improving the AC supply but
by avoiding the damage done by other distribution units. The simple solution
is normally the best – even if it’s not necessarily the easiest to execute.
The Qbase stands testament to the power of precision in thinking, design and
construction, with every element being carefully considered.
Qbase Mark II units are available with 4 (QB4) or 8 (QB8) outlets with US, EU
(Schuko) or Australian sockets, or 6 (QB6) outlets with UK sockets. The QB8
Mark II and QB6 Mark II units come with either a C-14 or C-20 IEC connector
input. When purchasing our UK version, only 6 outlets are available due to the
size of the UK sockets. The size of the unit cannot be expanded to fit further
sockets because the dimensions of the casework are critical to the units’
mechanical performance.
INSTALLATION
PLACEMENT
In order to deliver its full performance, the Qbase should be placed on a
stable solid surface, ideally on a dedicated shelf on an audio rack or amp
stand. It should be positioned to allow maximum separation between the
system’s AC power cords and signal leads.
CONNECTION
Each Qbase has an IEC input on one end. The unit is symmetrical so that this
can be arranged to the left or right as circumstances dictate. In order to
install your QRT unit, first switch off your system. Then connect the Qbase to
the wall, using a Nordost or other high quality power cord. The system’s units
should then be connected to the Qbase in the order shown by the diagrams on
the next page.
It is important to connect the linestage or integrated amplifier to the
Primary Earth socket located at the center of the ground star. Principal
sources should be connected in system order between the AC input and the
Primary Earth, balanced by power amp(s) and secondary sources on the other
side of this central socket.
While the high-quality WBT bindingpost should be connected to an independent
clean ground, the system will function as normal without this connection.
However, providing a clean signal ground is one of the most cost-effective
upgrades you can make to any audio or video system, as well as maximizing the
benefits of the Qbase Focussed Earth technology.
Finally, turn on the AC supply to the Qbase, followed by the system
components, running from sources first to power or integrated amplifier last.
Sit back and enjoy the results.
OPTIMIZING SYSTEM PERFORMANCE
Nordost’s extensive line of QRT audio enhancers includes the QKORE Ground
Unit, QPOINT Resonance Synchronizer, QSOURCE Linear Power Supply, QVIBE AC
Line Harmonizer, QKOIL AC Enhancer, and QLINE Ground Wire.
QRT products are designed to improve the performance of your system,
alleviating the impact of poor quality AC and DC power on your sensitive
electronics, providing proper grounding, and synchronizing electromechanical
resonances.
The effects are cumulative and best heard when QRT products are used as a
system. When arranged correctly, the effects include a lower noise floor,
increased image depth with tighter focus, wider soundstage, as well as
improved overtones, pacing, dynamic range and musical expression.
