amplifier module
brass instead of steel
The bolt holding the
heavy transformer
has been made
from brass
instead of steel
as this was also
found to make a
significant difference
to the low frequency
impact of the amplifier. Higher cost
well invested.
beauty to last
The finned centre section of the three part
fascia is machined from a solid aluminium
extrusion and is then fine paint finished. To
complete the fascia
assembly the two
extruded end caps
are machined,
bead blasted
and linished to
create an even
texture which is
then chemically
brightened and hard
black anodised or silver painted.

preparation
before you start
Make sure that all the components of your
system are disconnected from the AC
supply whenever you change any
connection.
Please be aware, when the front panel
switch is in the off position, this unit is still
connected to the mains supply. If this unit is
not to be used for some time, withdraw the
mains plug from the wall socket outlet.
positioning
The 250x3R is capable of consuming over
1000 Watts of electrical power during
demanding presentations. This results in
significant heat being dissipated.
• Please ensure that there is adequate
ventilation above and below the unit.
• The ventilation of the 250x3R should
not be impeded by covering the
ventilation slots with items such as
newspapers, table cloths, curtains etc.
• Place the 250x3R on an open flat
surface.
• Do not use in a cabinet or on a soft
surface such as a carpet.
• Do not place any other piece of
equipment on top of the 250x3R.
• Do not place naked flame sources such
as lighted candles on the 250x3R.
• Do not expose the 250x3R to dripping
or splashing liquids.
• Do not place objects filled with liquids,
such as vases, on or near the 250x3R.
safety first
To prevent the risk of electric shock follow
these instructions carefully. If in doubt
consult a qualified electrician.
vibration damping
The cover panel is
stiffened by
formed ribs, then
bonded with
viscoelastic
laminate to
provide a low Q
panel which
provides rapid
absorption of externally induced vibrations.
