Safety guidelines
CAUTION: To reduce the risk of electric shock, do not
remove cover (or back). No user serviceable parts inside.
Refer servicing to qualified service personnel.
WARNING: To reduce the risk of fire or electric shock, do not
expose this apparatus to rain or moisture.
The lightning flash with an arrowhead symbol within an equilateral
triangle, is intended to alert the user to the presence of uninsulated
dangerous voltage within the products enclosure that may be
of sufficient magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle is intended
to alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying
the product.
CAUTION: In Canada and the USA, to prevent electric shock,
match the wide blade of the plug to the wide slot in the
socket and insert the plug fully into the socket.
Important safety instructions
This product is designed and manufactured to meet strict
quality and safety standards. However, you should be aware of
the following installation and operation precautions:
1. Take heed of warnings and instructions
You should read all the safety and operating instructions
before operating this appliance. Retain this handbook for future
reference and adhere to all warnings in the handbook or on the
appliance.
2. Water and moisture
The presence of electricity near water can be dangerous.
Do not use the appliance near water - for example next to a
bathtub, washbowl, kitchen sink, in a wet basement or near a
swimming pool, etc.
3. Object or liquid entry
Take care that objects do not fall and liquids are not spilled into
the enclosure through any openings. Liquid filled objects such
as vases should not be placed on the equipment.
4. Ventilation
Do not place the equipment on a bed, sofa, rug or similar
soft surface, or in an enclosed bookcase or cabinet, since
ventilation may be impeded. We recommend a minimum
distance of 50mm (2 inches) around the sides and top of the
appliance to provide adequate ventilation.
5. Heat
Locate the appliance away from naked flames or heat
producing equipment such as radiators, stoves or other
appliances (including other amplifiers) that produce heat.
6. Climate
The appliance has been designed for use in moderate climates.
7. Racks and stands
Only use a rack or stand that is recommended for use with
audio equipment. If the equipment is on a portable rack it
should be moved with great care, to avoid overturning the
combination. 8. Cleaning
Unplug the unit from the mains supply before cleaning.
The case should normally only require a wipe with a soft, damp,
lint-free cloth. Do not use paint thinners or other chemical
solvents for cleaning.
We do not advise the use of furniture cleaning sprays or
polishes as they can cause indelible white marks if the unit is
subsequently wiped with a damp cloth.
9. Power sources
Only connect the appliance to a power supply of the type
described in the operating instructions or as marked on the
appliance.
10. Power-cord protection
Power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against
them, paying particular attention to cords and plugs, and the
point where they exit from the appliance.
11. Grounding
Ensure that the grounding means of the appliance is not
defeated.
12. Power lines
Locate any outdoor antenna/aerial away from power lines.
13. Non-use periods
If the unit has a standby function, a small amount of current will
continue to flow into the equipment in this mode. Unplug the
power cord of the appliance from the outlet if left unused for a
long period of time.
14. Abnormal smell
If an abnormal smell or smoke is detected from the appliance,
turn the power off immediately and unplug the unit from the wall
outlet. Contact your dealer immediately.
15. Servicing
You should not attempt to service the appliance beyond that
described in this handbook. All other servicing should be
referred to qualified service personnel.
16. Damage requiring service
The appliance should be serviced by qualified service personnel
when:
A. the power-supply cord or the plug has been damaged, or
B. objects have fallen, or liquid has spilled into the appliance,
or
C. the appliance has been exposed to rain, or
D. the appliance does not appear to operate normally or
exhibits a marked change in performance, or
E. the appliance has been dropped or the enclosure
damaged.
Safety compliance
This product has been designed to meet the IEC 60065
international electrical safety standard.

Connecting to power, loudspeakers and
other equipment
Follow the installation instructions for the integrated amplifier on
pages 4 and 5.
AUDIO IN - Connect this input to the output sockets of your pre-
amplifier or the
PRE OUT sockets of an integrated amplifier.
MONO LINK - The power amplifier can be adapted to provide
two mono loudspeaker outputs from a single input. Pull out
the link supplied and use it to connect the
L and R AUDIO OUT
sockets together. Using one power amplifier per loudspeaker
will enable you to bi-amplify bi-wireable loudspeakers.
This is particularly beneficial for top quality stereo installations
with a separate pre-amplifier, or where amplifiers are provided
for the left, centre and right channel loudspeakers in a five
speaker Dolby Pro Logic or Dolby Digital system.
Contact your Arcam dealer for more information.
Daisy chaining - The power amplifier can be connected to
further power amplifiers to drive more speakers (e.g. those in
other rooms or tri-amplified speakers, etc).
Connect the extra power amplifier inputs to the
AUDIO OUT
sockets on the power amplifier, left to left, right to right.
Installation: P90 power amplifer
Remote switching
By making a connection from the REMOTE IN socket of the P90
power amplifier to the
TRIG OUT socket of the A90 integrated
amplifier, you can use the A90 to switch the power amplifier on
and off. If configured in this way, the front panel
POWER button
of the A90 (or the
POWER/STANDBY button on the remote
control) switches both amplifiers on and off together. This facility
allows you to conceal the power amplifier yet still control it.
The connecting cable required is a 3.5mm to 3.5mm jack lead
(stereo or mono) and it is possible to connect several power
amplifiers to an A90 by daisy chaining from
TRIG OUT of one
P90 into the
REMOTE IN of the next.
Three channel option
The power amplifier can be upgraded from stereo to three
channels by adding a Third Channel Module: in this case, the
model is designated P90/3.
The module offers extra loudspeaker terminals together with a
third set of
AUDIO IN and OUT phono sockets and converts the
P90 into a 3 x 90W (RMS per channel into 8 Ξ©) amplifier suitable
for Home Cinema or multi-channel audio use.
Contact your Arcam dealer for further details.
