Installation: A80 amplier
Positioning the unit
Place your amplier on a level, 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 ow through the ventilation slots.
Connecting to loudspeakers
You can connect one or two pairs of loudspeakers to your
amplier, provided each pair is rated between 8–16Ω. If one or
both pairs have an impedance of less than 8Ω, the combined
load on the amplier falls below 4Ω and could cause an
overload. If so, the overload protection circuit may engage and
the amplier will not work.
To connect one pair of loudspeakers, use the SP1 terminals.
SP1 and SP2 terminals
4
Both sets of loudspeaker terminals can be muted by pressing
the MUTE button on the remote control. To switch SP1 and SP2
independently, use the front panel switches (see page 6,
2
) or
the remote control (see page 9).
Your amplier is tted with industry standard loudspeaker
terminals. The terminal accepts spade terminals or bare wires.
To connect a spade terminal or bare wire, unscrew the red (or
black) part of the loudspeaker terminal 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 speaker to the terminals on the back of
your amplier 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 amplier. Your loudspeaker cables may be
marked to show polarity (negative/– and positive/+), if not,
then the positive terminal can usually be identied by a ridge or
coloured marking.
Now connect your loudspeakers’ black (negative/–) terminals to
the black (negative/–) terminals on the amplier.
Ensure that no stray strands of inner wires are allowed to touch
another cable or the amplier’s casing. This can cause a short
circuit and damage your amplier!
Connecting to a power supply
Mains lead
The appliance is normally supplied with a moulded mains plug
already 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.
Wrong plug?
Check that the plug supplied with the unit ts your supply and
that your mains supply voltage agrees with the voltage setting
(115V or 230V) indicated on the rear panel of the unit
2
before
plugging in.
If your mains supply voltage or mains plug is different, consult
your Arcam dealer or Arcam Customer Support on +44 (0)1223
203200.
The product must be earthed.
Plugging in
Push the plug (IEC line socket) of the power cable supplied with
the unit into the socket (POWER INLET)
1
in the back of the
unit. Make sure it is pushed in rmly.
Put the plug on the other end of the cable into your power
supply socket and switch the socket on.
Standby power
For remote standby operation, the amplier’s control power
supply is kept powered up all the time the unit is connected to
the mains supply. The front panel power switch powers down
all other circuitry. Power consumption in this mode is less than
2.5W.
