QRT Qbase Mark II User manual

INSTRUCTION MANUAL
QBASE Mark II

The QRT Q
base
AC power distribution
units are specically 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 Q
base
stands testament to
the power of precision in thinking, design
and construction, with every element
being carefully considered.
Q
base
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 t further
sockets because the dimensions of
the casework are critical to the units’
mechanical performance.
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.

Placement
In order to deliver its full performance,
the Q
base
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 Q
base
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, rst switch off
your system. Then connect the Q
base
to
the wall, using a Nordost or other high
quality power cord. The system’s units
should then be connected to the Q
base
in the order shown by the diagrams on
the left.
It is important to connect the line-stage
or integrated amplier 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 binding-post
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 benets of the
Q
base
Focussed Earth technology.
Finally, turn on the AC supply to
the Q
base
, followed by the system
components, running from sources rst
to power or integrated amplier last. Sit
back and enjoy the results.

Optimizing System Performance
Nordost’s other QRT power products
consist of the QKORE Ground Unit, QV2
AC Line Harmonizer, QK1 AC Enhancer,
QX AC Purier, and QLINE Ground Wire.
They are designed to alleviate the
impact of poor quality AC power on
your sensitive electronics. By controlling
ground ow, and limiting RFI and timing
errors associated with the AC line, QRT
products bring AC power closer to
the desired “distortion-less condition”
without limiting the peak current of your
electronics.
QRT products are cumulative and their
effects are best heard when used as
a system. When arranged correctly,
the effects include a lower noise oor,
increased image depth with tighter
focus, wider soundstage, as well as
improved overtones, pacing, dynamic
range and musical expression.
