Setting up, wiring, using the unit for the first time
Unpacking
Carefully unpack the amplifier and store the original
packing material carefully. The carton and packing are
specially designed for this unit and will be needed again if
you wish to move the equipment at any time.
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 tempera-
ture, so that any condensation evaporates completely.
Caution!
Do not lift by the acrylic sheet parts.
Use the handles for unpacking, transporting and
setting up the unit.
Setting up
Before placing the unit on a sensitive surface please
check the compatibility of the lacquer and the unit's feet
on a non visible point.
The unit should be placed on a rigid, level base. When
placing the unit on resonance absorbers or anti-resonant
components make sure that the stability of the unit is not
reduced.
The amplifier should be set up in a well ventilated dry
site, out of direct sunlight and away from radiators.
The unit must not be located close to heat-producing
objects or devices, or anything which is heat-sensitive or
highly flammable.
When installing the amplifier on a shelf or in a cupboard it
is essential to provide an adequate flow of cooling air, to
ensure that the heat produced by the unit is dissipated
effectively. Any heat build-up will shorten the life of the
amplifier and could be a source of danger.
Caution!
There must be plenty of space around the amplifier
on all sides so that waste heat can dissipate freely.
Maintain a minimum distance of 20 cm to walls,
ceilings, shelves or other objects which could hinder
the circulation of cooling air.
Ensure that the fan on the underside of the amplifier
is not blocked or obstructed, and that air can enter
the fan unhindered.
Set up the amplifier in such a position that children
cannot touch it.

ATTENTION:
The valves and the valve cover must be
installed correctly before you use the unit for
the first time. The procedure is described in the
section '
Installing the valves '.
In case the tubes are already installed, please
check if they are correctly and firmly inserted in
their sockets.
For electrical safety: Device may not be
operated without tube cover!
Before using the unit for the first time the
carrying handles must be removed and the
retaining screws of the top cover must be
inserted and tightened firmly!
Mechanical de-coupling
The quality and characteristics of the base on which your
high-quality Hi-Fi equipment stands define the limits of
sound quality which can be achieved. The base surface
should be as heavy, rigid, hard and level as possible.
This amplifier is supplied with the new

vibration
absorbing feet. This feet feature internal damping
qualities which effectively de-couple the unit from the
base surface.
These features ensure that vibration in the base surface
is absorbed, and the delicate valves are protected from
interference caused by microphony effects.
The amplifier should be set up in an open position to
ensure that the vibration absorbers are able to work
perfectly. Do not allow any part of the case to touch walls
or other surfaces.
Note:
If the base surface is uneven you can screw the absorber
feet in or out to set the unit exactly level.
All units must be adjusted so that they are exactly
horizontal in all directions. Check that all feet make solid
contact with the base surface, i. e. that there is absolutely
no tendency for the unit to wobble.
Loudspeaker and signal cables
Loudspeaker cables and signal cables (inter-connects)
have a significant influence on the overall reproduction
quality of your sound system, and their importance should
not be under-estimated. For this reason
 recommends
the use of high-quality cables and connectors.
Our accessory range includes a series of excellent
cables and connectors whose properties are carefully
matched to our speakers and electronic units, and which
harmonise outstandingly well with them.
For difficult and cramped situations the

range also
includes special-length cables and special-purpose
connectors (e. g. right-angled versions) which can be
used to solve almost any problem concerning
connections and system location.
Mains cables and mains filters
The mains power supply provides the energy which your
sound system equipment needs, but it also tends to carry
interference from remote devices such as radio and
computer systems.
Our accessory range includes the specially shielded
'POWER FOUR' mains cable, ready-to-use 'POWER
LINE' mains cable with integrated shell-type filters and
the 'POWER BAR' mains filter distribution board which
prevent electro-magnetic interference from entering your
Hi-Fi system. The reproduction quality of our systems
can often be further improved by using these items.
If you have any questions regarding cabling please refer
to your specialist
 dealer who will gladly give you
comprehensive expert advice without obligation. We
would also be happy to send you our comprehensive
information pack on this subject.
