Installation: A65 and A75
Positioning the unit
Place your amplifi er on a level, fi rm surface.
Avoid placing the unit in direct sunlight or near sources of heat
or damp.
Ensure adequate ventilation. Do not place the unit in an
enclosed space such as a bookcase or cabinet as both of
these will impede air fl ow through the ventilation slots.
Connecting to loudspeakers
Your amplifi er is fi tted with loudspeaker terminals to BFA
(British Federation of Audio) standard specifi cation.
The terminal will accept spade terminals, bare wires or a
BFA plug. BFA plugs are available from your Arcam dealer. To
connect a bare wire or spade terminal unscrew the red (or
black) part of the loudspeaker terminal fi rst.
Insert the wire or spade terminal and screw it back up.
CAUTION: Do not over tighten the loudspeaker terminals or
use a wrench, pliers, etc., as this could cause damage to the
terminals which will not be covered under warranty.
Connect the right hand speaker to the terminals on the back of
your amplifi er marked R and the left speaker to the terminals
marked L.
Connect your loudspeakers so that the red (positive/+) terminal
on each loudspeaker is connected to the red (positive/+)
terminal on the amplifi er. Your loudspeaker cables may be
marked to show polarity (negative/– and positive/+), if not,
then the positive terminal can usually be identifi ed by a ridge
or coloured marking.
Now connect your loudspeakers' black (negative/–) terminals
to the black (negative/–) terminals on the amplifi er.
Ensure that no stray strands of inner wires are allowed to touch
another cable or the amplifi er's casing. This can cause a short
circuit and damage your amplifi er! Two pairs of speakers may
be connected at the same time provided each pair is rated
between 8 and 16Ω. If one or both pairs have an impedance
of less than 8Ω, the combined load on the amplifi er falls below
4Ω and could cause an overload. If so, the overload protection
circuit engages and the amplifi er will not work.

another room), connect them to these terminals. They can be
turned off easily by releasing the front panel switch
Volume control settings
It is important to realise that the position of the volume control
is not an accurate indication of the power delivered to your
loudspeakers. The amplifi er will often deliver its full power
long before the volume control reaches its maximum position
particularly when listening to heavily recorded compact discs.
However the amplifi er also has to be capable of giving full
power output from much lower level sources, such as tuners
and cassette decks. Using these sources, the volume control
setting may be much higher before distortion (audible overload)
sets in.
Connecting to a power supply
Wrong plug?
Check that the plug supplied with the unit fi ts your supply and
that your mains supply voltage agrees with the voltage setting
(120V or 230V) indicated on the rear panel of the unit.
If your mains supply voltage or mains plug is different, consult
your Arcam dealer or Arcam Customer Support on +44
(0)1223 203203.
Mains lead
The appliance is normally supplied with a moulded mains plug
already fi tted to the lead. If for any reason the plug needs to
be removed, it must be disposed of immediately and securely,
as it is a potential shock hazard when inserted into the mains
socket. Should you require a new mains lead, contact your
Arcam dealer.
Plugging in
Push the plug (IEC line socket) of the power cable supplied with
the unit into the socket ( ) in the back of the unit. Make sure
it is pushed in fi rmly.
Put the plug on the other end of the cable into your power
supply socket and switch the socket on.
