Overview
Arcam's PA720, PA240 and PA410
amplifiers
Arcam's PA720, PA240 and PA410 power amplifiers
provide class leading sound quality for the best
reproduction of your music.
Drawing on the many years of amplifier design
experience at Arcam, these products use the best
quality components and engineering practice to
produce amplifiers that will give many years of musical
pleasure and reliable service.
With a toroidal based power supply, acoustically
damped chassis, class G technology (PA240 &
PA720), parallel transistor output stages (PA240) and
exceptionally low levels of distortion and noise, the
PA720, PA240 and PA410 amplifiers are all capable of
reproducing music with all its original authority and
detail. Rest assured you will be hearing the music just as
the artist intended.
The PA720, PA240 and PA410 amplifiers are designed
to produce a level of performance that will truly bring
music to life.
Placing The Unit
Place the amplifier on a level, firm surface, avoiding
direct sunlight and sources of heat or damp.
Do not place the PA720, PA240 or PA410 on top of a
power amplifier or other source of heat.
Do not place the amplifier in an enclosed space such
as a bookcase or closed cabinet unless there is good
provision for ventilation. The PA720, PA240 and PA410
are designed to run warm during normal operation.
Do not place any other component or item on top
of the amplifier as this may obstruct airflow around
the heat-sink, causing the amplifier to run hot. (The
unit placed on top of the amplifier would become
hot, too).
PA720
Do not place your record deck on top of this
unit. Record decks are very sensitive to the noise
generated by mains power supplies which will be
heard as a background 'hum' if the record deck is too
close.
The normal function of the unit may be disturbed by
strong electromagnetic interference. If this occurs,
simply reset the unit with the power button, or move
the unit to another location.
Interconnect Cables
We recommend the use of high-quality screened cables
that are designed for the particular application. Other
cables will have different impedance characteristics
that will degrade the performance of your system (for
example, do not use cabling intended for video use to
carry audio signals). All cables should be kept as short as
is practically possible.
It is good practice when connecting your equipment to
make sure that the mains power-supply cabling is kept
as far away as possible from your audio cables. Failure to
do so may result in unwanted noise in the audio signals.

Power
The amplifier is supplied with a moulded mains plug
already fitted to the lead. Check that the plug supplied
fits your supply – should you require a new mains lead,
please contact your Arcam dealer.
If your mains supply voltage or mains plug is different,
please contact your Arcam dealer immediately.
Push the IEC plug end of the power cable into the power
socket on the back of the amplifier, making sure that it
is pushed in firmly. Plug the other end of the cable into
your mains socket and switch the socket on.
