T A POWER BAR 2+3 HD Power Conditioner Instruction Manual
Welcome.
We are delighted that you have decided to purchase a product. Your new POWER
BAR is mains distribution panel, which incorporates filters and other
protective circuitry specially designed to optimise the sound of high-quality
Hi-Fi components. The POWER BAR absorbs interference borne on the mains supply
and thereby prevents it reaching the system. It also prevents any interaction
between the individual system components, and effectively eliminates
interference caused by stray earth and shield currents. Severe voltage peaks
and surges often occur in thunderstorms and when equipment is switched on and
off. The distribution panel is also fitted with a voltage surge protection
system which reduces these peaks, and thereby helps to avoid potentially
terminal damage to the highly sensitive Hi-Fi electronics connected to it. We
are grateful for the faith you have shown in our company in purchasing this
product, and hope you enjoy many hours of undisturbed listening pleasure
provided by your POWER BAR mains distribution panel.

Interference can affect a Hi-Fi system by several different routes, and suitable measures need to be taken to avoid each potential problem.
Radiated interference
In the modern world we are constantly surrounded by high frequency electro-
magnetic interference fields. The mains leads and inter-connects of a typical
Hi-Fi system can act as aerials, picking up these fields and passing them on
to the devices to which they are connected. The POWER BAR mains panel and
POWER LINE mains leads are completely shielded all round, and the shield
prevents stray electrical fields reaching the internal conductors; instead
they are simply passed to earth. The construction of the conductors in mains
leads is arranged in such a way that open conductor loops cannot arise, and
this means that magnetic fields cannot occur within them.
Mains-borne interference
The wires of the mains power supply network also tend to act as aerials. A
further problem is that the mains supply is usually connected to a wide range
of equipment which generates powerful interference, such as computers,
switching units, control systems and motors, all of which inject a broad
spectrum of interference into the mains supply. This interference is passed on
via the mains network and inevitably reaches the sensitive Hi-Fi equipment –
unless prevented. All Hi-Fi components feature internal mains filters which
guard against this type of incoming interference, but it is always better to
suppress the interference before it reaches the equipment rather than provide
protection inside the unit itself. The POWER BAR provides effective protection
in the form of symmetrical PI filters with current compensated inductivity,
and these filters absorb a broad band of mains-borne interference and prevent
it reaching the system. The filters are complemented by ferrite rings which
are fitted to the outer sleeves of the POWER BAR supply cable and POWER LINE
mains leads. The ferrite rings suppress interference fields, prevent them
penetrating into the system, and also prevent them passing from device to
device.
Interference generated by other system components
The ferrite ring on the POWER BAR cable is movable, i.e. you can re-
position it to deal with the frequency spectrum which is causing you problems.
If interference occurs, adjust the position of the ferrite ring until the
optimum
Polarity indicator
It is not only external equipment which generates interference; the
individual components of a Hi-Fi system – especially digital machines – can
also cause problems. The design of the mains filter system prevents such
interference reaching other units via the mains wiring system. This is
achieved by decoupling the source device sockets from each other using
separate shield current blocking filters. Additionally all the sockets are
wired in a star-type cabling from a central connecting point.
The polarity of the mains connector can make a difference with many high-
quality Hi-Fi components, and it is important to establish this correctly. The
mains connector polarity can have a significant influence on the quality of
reproduced sound, depending on the winding technology employed for the mains
transformer and the design of the mains power supply section. The POWER BAR
includes a visual polarity indicator which enables you to check that polarity
is correct. The mains plug attached to the POWER BAR should be connected in
such a way that the indicator LED does not glow. If the polarity is set up in
this way, the marked terminal of each mains supply socket is the phase line,
and this should be connected to the correspondingly marked terminal of the Hi-
Fi unit connected to that socket. If you use the POWER LINE, all you have to
do is connect the marked terminal of the safety mains plug to the marked
terminal of the POWER BAR, and all the units connected to the distribution
panel will have correct polarity automatically, since the Euro mains
connectors which we use are polarised, i.e. they can only be connected one way
round.
Voltage surge protection
Modern Hi-Fi devices are very sensitive to voltage peaks and surges which
can occur in the mains power network due to a lightning strike or other event.
The POWER BAR mains distribution panel includes an integral surge protection
circuit designed to widen the safety margin for the components connected to
the panel. This circuit can suppress currents of up to 10000 Amps and more,
and thereby prevents almost all dangerous excess voltage peaks reaching the
devices connected to the system. If other electrical equipment in your house
is damaged by a lightning strike, please check the surge protection circuit of
the POWER BAR. In case of failure the polarity indicator LED lights up red.
Please note that, like a standard electrical fuse, this circuit may be
destroyed by a serious surge in voltage, so it is essential to ask your
specialist dealer to If you fail to do this the protective effect of the
system may be lost.
Important notes
The operation instructions, the connection guidance and the safety notes are for your own good – please read them carefully and observe them at all times. The operating instructions are an integral part of this device. If you ever transfer the product to a new owner please be sure to pass them on to the purchaser to guard against incorrect operation and possible hazards.
If the unit gets very cold (e. g. when being transported), condensation may form inside it. Please do not switch it on until it has had plenty of time to warm up to room temperature, so that any condensation evaporates completely.
Care of the unit
Disconnect the mains plug at the wall socket before cleaning the case. The
surfaces of the case should be wiped clean with a soft, dry cloth only. Never
use solvent-based or abrasive cleaners! Before switching the unit on again,
check that all cables are plugged in correctly
Enclosure openings
Liquid or particles must never be allowed to get inside the unit through
the ventilation slots. Mains voltage is present inside the unit, and any
electric shock could cause serious injury or death. Never exert undue force on
mains connectors. Protect the unit from drips and splashes of water; never
place flower vases or fluid containers on the unit. Do not place naked flame
sources, such as candle lights on the device.
The device is designed to operate in a temperate climate and altitudes up to 2000 m above sea level. The range of permissible operating temperatures is +10 … +30°C.
Overload
Make sure that the connected devices do not exceed the maximum total load
capacity (see Technical data) of the POWER BAR. Connecting loads which
together exceed the total load capacity of the POWER BAR may result in fire
and destruction of the POWER BAR.
Service and damage
The case should only be opened by a qualified specialist technician.
Repairs and fuse replacements should be entrusted to an authorised specialist
workshop. With the exception of the connections and measures described in
these instructions, no work of any kind may be carried out on the device by
unqualified persons.
If the unit is damaged, or if you suspect that it is not functioning
correctly, immediately disconnect the mains plug at the wall socket, and ask
an authorised specialist workshop to check it.
