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.
A90/P90

Connecting to loudspeakers
The red and black terminals on the back of the ampliers 4
are used to make the connections to the 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.)
The pair designated ‘speaker 1’ (SP1) are connected to the
lower set of terminals, while the pair designated ‘speaker 2’
(SP2) are connected to the upper set of terminals. To connect
one pair of loudspeakers, use the SP1 terminals.
When connecting the speaker terminals of the amplier with
the terminals on the speakers, make sure that like polarities
are matched (i.e., match ‘+’ with ‘+’ (usually red) and ‘–’ with ‘–’
(usually black)). Mismatching of polarities will result in a weak
central sound, unclear orientation of the instruments and the
sense of direction of the stereo being impaired.
There are two options for connecting the speaker cable to the
amplier:
Using bare wire ended leads:
1. Strip back the insulation on the wire to reveal about 2cm
of conductor (the metal inside the cable).
2. If the conductor is stranded, twist the strands together
tightly to avoid loose strands making contact with the
adjacent terminals or the back panel.
3. Loosen the terminal by turning it anti-clockwise
4. Insert the twisted wire through the hole in the terminal.
5. Tighten by turning clockwise.
When making connections with stranded bare ended wires, take
great care that no individual strands of wire come into contact
with the adjacent terminals or with the back panel. If this
should happen, it will cause a short circuit on the output of the
amplier and could damage the amplier.
Wiring your loudspeakers
Using spade terminals:
1. Loosen the terminal by turning it anti-clockwise
2. Insert the spade connecter under the terminal.
3. Tighten by turning clockwise.
Connecting to a power supply
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.
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.
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 2W.
This means that even though the power switch is off, it may be
possible to hear a slight residual hum coming from the mains
transformer inside the amplier. This is perfectly normal. If the
unit is to be left unused for an extended period, we recommend
that it is disconnected from the mains supply by switching it off
at the wall socket.
Connecting to other equipment
The use of high quality interconnect cables to and from your
amplier is recommended to ensure the best sound quality.
Sockets marked L (and R) on your amplier should only be
connected to sockets marked L (and R) on other equipment. All
the line inputs have the same sensitivity and may be used with
equipment other than that labelled, if needed.
TAPE1/RECORD OUT 8 – Connect these output sockets
to the input sockets of your cassette deck (usually labelled
RECORD).
TAPE1/PLAY IN 9 – Connect these input sockets to the
output sockets of your cassette deck (usually labelled PLAY). If
you do not have a cassette deck you can use this input for other
(line level) equipment, such as a CD player, tuner, VCR, etc., but
not a turntable.
VCR/TAPE2 RECORD OUT bk – These output sockets can
be connected to the input sockets of VCR/second recorder
(usually labelled RECORD).
VCR/TAPE2 PLAY IN bl – Connect these input sockets
to the output sockets of your VCR/second recorder (usually
labelled PLAY). Alternatively, you can use this input for other
(line level) equipment such as a CD player, tuner, etc., but not a
turntable.
DVD bm – Connect this input to the audio outputs of a DVD
player.
AV bn – Connect this input to audiovisual equipment such as a
VCR, laserdisc player, satellite or Nicam tuner.
TUNER bo – Connect this input to the audio outputs of your
radio tuner.
CD bp – Connect this input to the audio outputs of your CD
player or DAC (digital to analogue converter).
AUX bq – Connect this input to the audio outputs of any unit
with a line level output, e.g. tape deck, tuner etc.
NOTE: The AUX inputs must not be used if the phono module
is tted. When this is tted AUX becomes an output carrying
the equalised phono signal at line level.
TRIG OUT AND REMOTE IN 3 (12V in and out) – These
connections are intended for use in multi-room installations.
TRIG OUT – This output provides a 12V signal whenever the
unit is switched on (i.e., not off or in standby). This signal
can be used to switch on automatically power ampliers
(or other equipment) connected to the A90, as they will
come on when the A90 is activated. This is useful if the
power amplier is remote from the A90, or otherwise
difcult to access.
REMOTE IN – This allows remote control signals to be received
by the A90 if the remote sensor is covered (or otherwise
not ‘visible’ to the remote control). An external sensor
is used to receive the signals from the remote control,
which are then fed to the A90 (into this input) using a
suitable cable. Remote control signals acceptable to the
A90 must be in modulated RC5 format, with a voltage
level of between 5V and 15V.
Note that in normal use there is no need to make any
connections to these sockets. If you would like to make use of
these features, please contact your dealer for more advice on
how to make the connections and on what type of cable to use.
Pre/power amplier connections
PWR IN
amplier, connect the output of your pre-amplier to the PWR IN
sockets.
Press in the PRE/PWR switch 7 on the rear panel to
select separate pre-amp/power amp mode. Under these
circumstances your A90 has exactly the same specication and
performance as a power amplier (see page 10).
PRE OUT
amplier, connect the PRE OUT sockets to the input sockets
of your power amplier. With a power amplier of the correct
gain (e.g. the P90 power amplier) you can bi-amplify (‘bi-amp’)
suitable loudspeakers, giving signicant improvements in sound
quality (see page 12).

Front panel controls
This section describes how to operate your amplier.
If your amplier has not been installed for you, you should
rst read the section ‘Installation: A90 integrated amplier’ on
page 4.
POWER (and power indicator light)
Switches the unit on and off. (You can also switch the amplier
into standby mode with the remote control handset.)
The light indicates the status of the amplier. A red light means
the amplier is in standby mode (press the POWER/STANDBY
button on the remote control, or the POWER button on the front
panel, to switch between standby and powered-up modes).
When you switch your amplier on, the light glows amber for a
few seconds, during which time the speakers are disconnected.
The light changes to green when the amplier is ready for use.
The light may ash if a fault has occurred – the fault type is
shown on the display. You should unplug the amplier and leave
it for a few minutes before reconnecting. If the fault cannot be
cleared, unplug your amplier and contact your Arcam dealer.
Source selectors 2
These buttons select the source connected to the
corresponding input. A light above the relevant button indicates
which input is currently selected and it will also usually be
shown on the display.
VCR
4
This input is similar to the other line level inputs on the amplier
and may be used with a VCR or a second recording unit (e.g.
cassette deck).
TONE
6
Switches the tone circuits on and off, including settings for
individual sources. Note that the tone LED does not light unless
a tone setting has been made. (see page 8).
Control knob, SELECT and ENTER
The control knob has two functions:
as a volume control, to adjust the output of loudspeakers
and headphones connected to the amplier, and of the
pre-amp output (PRE OUT).
when used in conjunction with the SELECT and ENTER
buttons, to customise amplier settings (see page 8).

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 amplier often delivers its full power long
before the volume control reaches its maximum position,
particularly when listening to heavily recorded compact discs.
However the amplier 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. To compensate for this, the input levels of each source
may be individually adjusted to avoid accidental overload (see
page 8).
SP1 and SP2
These buttons allow you to select and deselect the main (SP1)
and secondary (SP2) set of speakers attached to your amplier.
The light above each button glows if the corresponding
speakers are currently selected. (If both lights are out the
amplier will appear not to work, as all speakers are switched
off!)
PHONES
This socket accepts headphones with an impedance rating
between 8Ω and 2kΩ, tted with a 1/4-inch stereo jack plug.
If you wish to listen on headphones only, use the SP1 and SP2
buttons (if necessary) to mute the speakers. The headphone
socket is always active.
Remote control receiver
The remote control’s infrared receiver is positioned to the left
of the RECORD button. Ensure the receiver is in a clear line of
sight from the remote control to allow signals to be received.
MODE, UP and DOWN
These buttons are mainly for use with future optional modules,
however the UP and DOWN buttons are used with the basic A90
amplier to move the cursor when customising the ‘Welcome
message’ (see page 8).

Recording
With the Arcam A90 it is possible to listen to and record from
one source, or to listen to one source while recording another.
Both sets of tape sockets are identical in sensitivity and suitable
for use with almost any type of recorder (cassette, CDR, MD,
VCR, reel-to-reel, etc.). The record signal is sent to both the
TAPE and VCR output sockets.
Eng lis h
RECORD
To record the currently selected source, press RECORD until
the display shows ‘RECORD SOURCE’. After a few seconds the
display reverts to showing the volume level and you are ready
to record.
To listen to one source while recording another, press RECORD
again until the display shows ‘RECORD’ followed by the name
of an input (e.g. ‘AUX’, ‘CD’, ‘TUNER’, etc.). Now press the
source selector button on the front panel for the source you
wish to record. Your selection is shown on the display for a few
seconds, after which it reverts to showing the volume level and
you are ready to record.
The RECORD button can also be used as a second zone
selector, sending a source signal at line level to a second
amplier operating in another room. If you need help with this,
contact your Arcam dealer or Arcam customer support.
bk
Tape-to-tape copying (dubbing)
You can perform tape dubbing from VCR to TAPE, but not from
TAPE to VCR.
For example, to copy from a cassette recorder connected to
the VCR socket to a cassette recorder connected to the TAPE 1
socket, rst use the RECORD button as explained above and
select ‘RECORD VCR’. This routes the VCR signal to the TAPE
output.
Set the cassette recorder connected to the TAPE socket into its
record mode and the other to playback mode to start dubbing.
TAPE
5
To play back the recording from a cassette deck attached to
the TAPE 1 input, press TAPE. ‘TAPE 1’ is shown on the display.
Selecting this input overrides the other source selectors.
It is also possible to monitor a recording while it is being made,
provided your cassette deck is a 3-head type. To do this, press
TAPE. Switching this button in/out allows an A/B comparison
between the source signal and the recorded signal.

Tone Control – Global or Per source. This
species the scope of changes for ‘Bass’ and
‘Treble’ tone settings. The default setting is ‘Global’
which affects all inputs equally. ‘Per source’ allows
you to set tone controls for individual inputs: once
set, the amplier remembers tone settings for
each input.
Processor Mode – This mode enables you to
adjust the gain of the amplier. The amplier
can then be used to drive the front left and right
speakers in a surround sound system when
fed from a separate processor. You can then
control the volume of the entire system using the
processor, feeding the sound into the TAPE input.
Set the gain to match the ampliers that drive your
other loudspeakers.
Welcome message – You can change the
power on Welcome message from ‘Arcam
INTEGRATED AMP’ to display your name,
postcode, etc. When customising the message,

will enable you to bi-amplify bi-wireable loudspeakers.
This is particularly benecial for top quality stereo installations
with a separate pre-amplier, or where ampliers are provided
for the left, centre and right channel loudspeakers in a ve
speaker Dolby Pro Logic or Dolby Digital system.
Contact your Arcam dealer for more information.
“Daisy chaining” – The power amplier can be connected to
further power ampliers to drive more speakers (e.g. those in
other rooms or tri-amplied speakers, etc).
Connect the extra power amplier inputs to the AUDIO OUT
sockets on the power amplier, left to left, right to right.
Remote switching
By making a connection from the REMOTE IN socket of the P90
power amplier to the TRIG OUT socket of the A90 integrated
amplier, you can use the A90 to switch the power amplier on
and off. If congured in this way, the front panel POWER button
of the A90 (or the POWER/STANDBY button on the remote
control) switches both ampliers on and off together. This facility
allows you to conceal the power amplier 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
ampliers to an A90 by ‘daisy chaining’ from TRIG OUT of one
P90 into the REMOTE IN of the next.
Three channel option
The power amplier 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 8Ω) amplier suitable
for Home Cinema or multi-channel audio use.
Contact your Arcam dealer for further details.

POWER (and power indicator light)
Switches the unit on and off. The light indicates the status of the
amplier.
When you switch your amplier on, the light glows amber for a
few seconds, during which time the speakers are disconnected.
The light changes to green when the amplier is ready for use.
A red light means the amplier is in standby mode.
The power light may ash if a fault has occurred, with the colour
of the ashing light indicating the nature of the fault:
green – a D.C. offset fault has occured
amber – a thermal fault has occured (the amplier is too
hot)
red – a short circuit fault has occured (this can happen if
the speaker cables are not connected correctly and are
making contact with each other or with the chassis)
red and amber – more than one fault has occured.
Except for a thermal fault, if one of the above faults is detected
by your amplier the unit waits for six seconds before checking
to see if the fault has cleared. If the fault clears within six
seconds, then the unit continues operation; otherwise the unit
shuts itself down. In the case of a thermal fault, the unit waits
until its sensor temperature lowers before resuming operation.
If the amplier has shut itself down, you should unplug the
amplier and leave it for a few minutes before reconnecting. If
the fault cannot be cleared, unplug your amplier and contact
your Arcam dealer.
SP1 and SP2
These buttons allow you to select and deselect the main
(SP1) and secondary (SP2) sets of speakers attached to your
amplier. An indicator light shows which set of speakers are
currently selected.
NOTE: If both lights are out the amplier will appear not to
work, as all speakers are switched off.

Before you start
WARNING: Do not make any connections to your
amplier while it is switched on or connected to the
mains supply.
Before switching on please check all connections
thoroughly, making sure bare wires or cables are not
touching the amplier in the wrong places (which could
cause short circuits) and you have connected positive
(+) to positive and negative (–) to negative.
Always ensure that the volume control on your amplier
is set to minimum before starting these procedures.
Bi-wiring your loudspeakers
Bi-wiring improves the sound of your system because it divides
the high and low frequency signal currents into separate
speaker cables. This avoids signal distortions arising from the
high and low frequency currents interacting with one another
within a single cable, as in conventionally wired systems.
You will need:
Speakers – with four input terminals each: these will be marked
HF (High Frequency) and LF (Low Frequency).
Loudspeaker cables – two pairs of cables per loudspeaker
(which may be joined at the amplier end if your amplier has
only one pair of output terminals per channel), or a suitably
terminated cable set.
How to bi-wire loudspeakers
1. Remove the terminal links on the rear of your
loudspeakers
Bi-amping your system
The performance of your system can be further enhanced over
that achieved with bi-wiring, by extending the principle one
stage further to include separate amplication for the low and
high frequency drive units in each loudspeaker enclosure.
Connect the integrated amplier to the high frequency (HF)
terminals and connect the power amplier to the low frequency
(LF) terminals.
You will need:
Speakers – with four input terminals each (as with bi-wiring):
these will be marked HF (High Frequency) and LF (Low
Frequency).
Two ampliers – one of these would be the A90 and the other
an Arcam power amplier (e.g. P90).
Loudspeaker cables – two pairs of cables per loudspeaker or a
suitably terminated cable set.
Interconnect cables – one pair of high quality interconnect
cables.
How to set up a bi-amped system
1. Remove the terminal links on the rear of your
loudspeakers.
WARNING: This step is essential or damage to
your amplier may result which is not covered
under warranty.
2. Connect the cables as shown in the diagram below,
ensuring correct polarity at all times.
3. Use the interconnect cables to connect the PRE OUT
sockets of the A90 to the corresponding AUDIO IN
sockets of the power amplier.

Service information
Before returning your amplier for service, please check the
following:
Sound cuts out for no reason
If the temperature of the internal heatsink rises above a safe
level, then a thermal cutout inside the amplier will operate.
The power indicator on the front panel ashes and the
protection system temporarily removes the power to the
speakers. The system resets itself as the heatsink cools down.

With two pairs of low impedance speakers connected,
overloads are more likely. Overloading the amplier may
cause it to shut down because of overheating.
Note that because of the high output voltage from a CD
player, it is possible to drive the A90 at full power even
though the volume is not set at maximum.
Amplier does not switch back on
The A90 and P90 ampliers have a protection mechanism
which is activated if you switch the unit on immediately after
turning it off. If this mechanism activates, wait 30 seconds then
try again.

Mise en place de l’appareil
Poser l’amplicateur sur une surface plane et ferme.
Eviter de l’exposer directement aux rayons du soleil ou de le
placer près d’une source de chaleur ou d’humidité.
S’assurer qu’il est correctement ventilé. Ne pas le placer dans
un espace clos, tel qu’une bibliothèque ou un meuble, qui
risquerait d’empêcher la circulation de l’air dans les orices
prévus à cet effet.
Câblage des hauts-parleurs
Branchement des haut-parleurs
A90/P90
18
Les bornes rouges et noires 4 qui se trouvent à l’arrière
des amplicateurs servent à brancher les haut-parleurs. Vous
pouvez connecter une ou deux paires de haut-parleurs à votre
amplicateur, à condition que chacune ait une impèdance
comprise entre 8 et 16Ω. (Si l’une ou les deux paires ont
une impèdance infèrieure à 8Ω, la charge combinèe de
l’amplicateur est infèrieure à 4Ω, ce qui risque de provoquer
une surcharge.) La paire dèsignèe ‘haut-parleurs 1’ (SP1)
se branche sur les bornes du bas, et celle dèsignèe ‘hautparleurs 2’ (SP2) se branche sur les bornes du haut. Pour
connecter une paire de haut-parleurs, utilisez les bornes SP1.
Lorsque vous reliez les bornes de l’amplicateur à celles des
haut-parleurs, assurez-vous que les polaritès correspondent
(branchez le ‘+’ sur le ‘+’, en gènèral rouge et le ‘–’ sur le ‘–’, en
gènèral noir). Une erreur de ce branchement se traduit par un
son central faible, une orientation imprècise des instruments et
nuit au sens de la direction du son.
Le l du haut-parleur peut être branchè sur l’amplicateur de
deux façons :
En dènudant l’extrèmitè des ls :
1. Retirez l’isolant pour dègager environ 2 cm de
conducteur (le mètal à l’intèrieur du l) ;
2. S’il s’agit d’un conducteur multibrin, torsadez les brins
en les serrant bien pour ne pas risquer qu’un brin soit
en contact avec les bornes adjacentes ou le panneau
arrière ;
3. Desserrez la borne en la tournant vers la gauche ;
4. Insèrez le l torsadè dans le trou de la borne ;
5. Resserrez la borne en la tournant vers la droite.
Lorsque vous faites un branchement en dènudant l’extrèmitè
des ls, vèriez bien qu’aucun brin ne soit en contact avec les
bornes adjacentes ou avec le panneau arrière. Il se produirait
alors un court-circuit à la sortie de l’amplicateur, ce qui
risquerait de l’endommager.
En utilisant des bornes embrochables :
1. Desserrez la borne en la tournant vers la gauche ;
2. Insèrez la cosse rectangulaire sous la borne ;
3. Resserrez la borne en la tournant vers la droite.
Branchement sur une source d’alimentation électrique
S’agit-il de la prise adéquate ?
Vériez que la prise livrée avec l’appareil correspond à
l’alimentation et que la tension du secteur correspond au
réglage prédéni (115V ou 230V) indiqué sur le panneau arrière
de l’appareil 2.
Si vous disposez d’une tension d’alimentation secteur ou d’une
che secteur différente, consultez votre revendeur Arcam ou le
service clientèle Arcam au +44 1223 203200.
Le produit doit être mis à la terre.
Câble de liaison au secteur
L’appareil est normalement livré avec une prise secteur moulée
déjà montée sur le câble. Si vous devez, pour une raison
quelconque, retirer la prise, jetez-la immédiatement dans un
réceptacle approprié. En effet, son branchement sur la prise
murale risque de provoquer une électrocution. Si vous avez
besoin d’un nouveau câble de liaison au secteur, contactez
votre revendeur Arcam.
Branchement
Enfoncez la che (prise de ligne IEC) du câble d’alimentation
livré avec l’appareil dans la prise (POWER INLET) 1 située
à l’arrière de ce dernier. Vériez qu’elle est correctement
enfoncée.
Introduisez la prise située à l’autre extrémité du câble dans votre
prise d’alimentation secteur, et mettez cette dernière sous tension.
