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).

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.

 

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.
