INTRODUCTION
The P7 Multi-channel Power Amplifier is built to Arcam’s traditional
high quality design and manufacturing standards. It is an extremely
high-performance multi-channel power amplifier, offering up to 150W
per channel. It is obviously well suited to multi-channel home cinema
amplification, and also provides superb quality stereo performance with
two-channel sources. The P7 is an ideal partner for the FMJ AV8 Preamp Processor.
Each power amplifier module is identical, and is electrically isolated from
the other modules by opto-isolated circuitry which ensures that each
amplifier module has its own isolated supply. This allows the amplifier to
give excellent channel separation and very low distortion.
The P7 also has input and output phono sockets for the signal being fed
to each channel, to allow the signal to be passed on to additional power
amplifiers to drive loudspeakers in other rooms or to bi-amplify any of
the speakers. If the P7 is being used to drive a five-channel surround
sound system, then the spare two modules (‘L surround rear’ and ‘R
surround rear’) can be used in conjunction with the main (‘L front’ and
‘R front’) modules to bi-amplify suitable front left and right speakers.
The P7 can be easily integrated with various types of loudspeakers,
including those that are THX certified. Being THX certified means that
the P7 has passed the rigorous THX Ultra2 specification enabling it to
reproduce THX Surround EX signals from both Dolby Digital and DTS
soundtracks, when fed from a THX Surround EX-capable processor,
such as the Arcam AV8.
The customised installation of the P7 to a listening room is an
important process which requires care at every stage. For this reason,
the installation information is very comprehensive and should be
followed carefully. This manual has been written with the assumption
that the installer is familiar with the installation of audio/video systems.
SPEAKER INSTALLATION
The P7 allows connection of up to seven loudspeakers. All speakers,
with the exception of the subwoofer, should be arranged around your
normal viewing/listening position (see diagram). The subwoofer can be
placed almost anywhere and we recommend experimenting with it in
various positions to obtain the best result.
Position your front left and right speakers to achieve a good stereo
image for normal musical reproduction. If they are placed too close
together there will be a lack of spaciousness. Alternatively if they are
placed too far apart the stereo image will appear to have a large hole
in the middle and will be presented in two halves.
The centre speaker allows for a more realistic reproduction of dialogue
and centre sounds as well as wider and better imaging for stereo effects
and background sounds for home cinema use. Do not compromise
on the quality of your centre speaker as it carries all the dialogue for a
home cinema system.
The surround left and right speakers reproduce the ambient sound and
effects present in a multi-channel home cinema system.
The surround back left and surround back right speakers are used to
add extra depth, a more spacious ambience and sound localisation.
A subwoofer will greatly improve the bass performance from your
system. This is useful for reproducing special cinema effects, especially
where a dedicated LFE (Low-Frequency Effects) channel is available, as
with Dolby Digital or DTS Digital Surround encoded discs.
English
CABLES
We recommend the use of high quality screened analogue, digital
and video cables as inferior quality cables will degrade the sound and
picture quality of your system. Only use cables that are designed for
the particular application as other cables will have different impedance
characteristics that will degrade the performance of your system.
Speaker cable length should be minimized and low resistance wire
should be used throughout to ensure efficient power transmission and
avoid audible distortion.
For optimum soundstage imaging, try to keep the right and left speaker
cables the same length. You are also advised to route the signal cables,
speaker cables and mains power cables away from each other to
minimize interference.
Contact your Arcam dealer or installer for details of suitable cables.

Installation
POSITIONING THE UNIT
Place the amplifier on a level, firm surface.
Avoid placing the unit in direct sunlight or near sources of heat
or damp.
Do not place the unit on top of a power amplifier or other
sources of heat.
Ensure adequate ventilation.
The P7 has a variable speed fan for cooling. If the unit is placed
in an enclosed space, such as a bookcase, equipment rack or
cabinet, ensure that there is adequate space and ventilation in
the enclosure for air to flow through the ventilation slots and
cool the amplifier. Inadequate cabinet ventialtion may cause the
P7 to shut down due to thermal overload.
The amplifier is designed to run warm during normal operation.
Ensure that the equipment rack or stand can support the 31kg
weight of the unit.
CONNECTING TO A PRE-AMPLIFIER
ANALOGUE AUDIO INPUTS
It is imperative to connect the pre-amplifier outputs to the module for
that particluar channel, e.g., connect the left surround output to the
module that will be driving the left surround speaker.
All modules are identical. However, we advise you to make connections
corresponding to rear panel labelling, since the amplifier modules are
muted in pairs. Due to the layout of the power supply circuitry in the
P7, you should connect the correct input signal and loudspeaker to
the recommended channel, or the left/right stereo imaging will not be
optimum.
The outputs from the pre-amplifier should be connected to the AUDIO
IN inputs on the P7. Be sure to note which channel from the pre-
amplifier is connected to which power amplifier module, so that the
correct speaker can be connected to that module and the correct
channel identity can be maintained.
If you wish to use four modules to bi-amplify a pair of speakers, or
would like to bi-amplify using another power amp, then you can take
the signal for that channel and feed it on to the additional modules
using the AUDIO OUT phono socket on that module. The signal is then
fed in to the first module, but also fed on to the second module so that
both modules can bi-amplify the loudspeaker.
12V TRIGGER INPUT
If your pre-amp provides a 12V Trigger output, it can be connected to
the 12V TRIGGER IN socket using a 3.5mm jack. This enables the P7 to be
turned on remotely from the pre-amp.
Note that the trigger input is only active when the central power
button on the front panel is depressed.

CONNECTING TO LOUDSPEAKERS
The speakers should be connected to the loudspeaker terminals, as
per the correct input signal. In other words, the Centre channel speaker
should be connected to the module that is being fed the signal for the
Centre channel, and so on, for all the channels.
As with all speaker connections, ensure that polarity is maintained
when connecting the speakers (i.e., red (+) to red; black (–) to black).
To bi-wire or bi-amplify your speakers, refer to the section towards the
end of this handbook where diagrams are provided. If you are unsure as
to how your system should be connected, or need advice on bi-amping,
please consult your Arcam dealer.
CONNECTING TO A POWER SUPPLY
MAINS LEAD
The appliance is normally supplied with a moulded mains plug already
fitted 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 fits your supply and that your
mains supply voltage agrees with the voltage setting (100V, 115V or
230V) indicated on the rear panel of the unit.
If your mains supply voltage or mains plug is different, consult your
Arcam dealer or Arcam Customer Support on +44 (0)1223 203200.
PLUGGING IN
Push the plug (high current IEC line socket) of the power cable supplied
with the unit into the POWER INLET socket in the back of the unit. Make
sure it is pushed in firmly.
The P7 has been designed so that a standard-rating IEC cable (which
has insufficient current rating) cannot be plugged into the P7. Only high
current power cables can be connected.
Put the plug on the other end of the cable into your power supply
socket and switch the socket on.

Operating your P7
P7 MULTICHANNEL POWER AMPLIFIER
1 2 3 4 5 6 7
FRONT PANEL LAYOUT
The P7 front panel has a single control: a centrally located power on/off
button.
POWER
Switches the unit on and off. Note that the modules are turned on
individually to stagger the surge created when a powerful amplifier
is switched on (i.e., it provides a ‘soft start’). This reduces the surge
current drawn from the domestic power supply.
STATUS LEDS
A separate LED indicates the status of each of the seven channels of
the P7.
The LEDs cycle through red, orange, then green to indicate the status
from powered-up (initialised), stabilised and active respectively.
All LEDs are off in standby mode.
OPERATING PROCEDURE
Once the relevant connections have been made, the P7 can be
switched on using the central button on the front panel.
SWITCHING ON
It is recommended that you switch on your pre-amp or controller
before powering up the P7 power amp.
Normal powering up is indicated by the following sequence of front
panel LED indicators:
1. On pressing the power switch, all LEDs turn red.
2. After approximately half-a-second, the centre LED turns amber.
3. The LEDs continue turning amber from the centre to the edges
in pairs, with intervals of approximately one second.
4. The centre LED turns green and a relay ‘click’ is heard.
5. The LEDs continue turning green from the centre to the edges
in pairs, along with relay ‘clicks’, with intervals of approximately
one second.
If the LEDs do not follow this sequence when the P7 is powered up,
or behave abnormally at any time during use, then consult the table of
‘Fault status indicators’ on page 11 to discover why the amplifier is in
protection mode.
SWITCHING OFF
To shut down, switch the P7 power amp off first, followed by the preamp or controller.
This eliminates the chance of any ‘thumps’ or power spikes being fed
through to the power amplifier and potentially causing damage to the
system.
NOTE: It is recommended that if the unit is switched off, then it
should not be switched on again for at least 20 seconds from when
it was turned off. This allows the amplifier’s power supply to discharge
fully before it is switched on again.

BEFORE YOU START
WARNING: Do not make any connections to your amplifier 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 amplifier 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 amplifier 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 –) and LF (Low Frequency + and –).
Loudspeaker cables – two pairs of cables per loudspeaker (which
may be joined at the amplifier end if your amplifier has only one pair
of output terminals per channel, as is the case with P7), or a suitably
terminated cable set.
How to bi-wire loudspeakers
1. Remove the terminal links on the rear of your loudspeakers.
NOTE: If you do not remove the shorting links from the
speaker terminals, the speakers will still be single-wired!
2. Connect the cables as shown in the diagram below, ensuring
correct polarity at all times.
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 amplification for the low and high frequency drive
units in each loudspeaker enclosure.
To bi-amplify your speakers, connect the speaker terminals from one
module to one pair of terminals on the speaker. Connect another
module, or one channel of a separate power amp, to the other pair of
terminals on the speaker, so that two amplifier channels are connected
to that speaker; one for low frequencies and one for high frequencies.
Ensure that in all cases, the positive terminals on the speakers are
connected to the positive (red) terminals on the amplifier, and similarly
for the negative (black) terminals.
NOTE: In order to bi-amplify your speakers, your speakers will need
to be bi-wirable, and have positive and negative terminals for both high
frequency (HF) and low frequency (LF) information. If your speakers are
bi-wirable, ensure that the links between the HF and LF terminals are
removed.
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 amplifier
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 interconnect cables to connect the OUT socket of the first
channel to the corresponding IN socket of the adjacent channel
of the power amplifier.

sequence of LEDs.
NO SOUND IS PRODUCED
Check that:
the correct input has been selected on the pre-amp.
you have assigned the digital input to the correct input source.
the volume is turned up to a reasonable level and ‘MUTE’ is not
displayed on the front panel display on the pre-amp.
your power amplifier(s) are turned on and working correctly.
SOUND IS POOR AND BADLY DISTORTED
Check that:
all cables are making a good connection. If necessary withdraw
the cable from the connector and plug it back in again. (Turn the
power off before doing this.)
you have selected the correct size of speakers to suit your
system in the setup menu of the processor or pre-amp.
HUM ON AN AMPLIFIER OUTPUT
Check that:
all cables are making a good connection. If necessary withdraw
the cable from the connector and plug it back in again. (Turn the
power off before doing this.)
if the hum originates from a ground loop caused by an aerial,
satellite dish or cable supply, you should contact your aerial
contractor.
the signal (interconnect) leads are not wrapped around a mains
lead.
try switching the ground lift on the back panel of the processor
(if available).
THERE IS RADIO/TELEVISION RECEPTION
INTERFERENCE
The P7 has been designed to a very high standards of electromagnetic
compatibility.
Check that:
the aerial/dish cable is routed as far as possible from your P7 and
its cabling.
the cabling used from the aerial/dish is of high quality and
screened.
repositioning the receiving aerial/dish as far as possible from your
P7 and its cabling may bring an improvement.
if the problem persists, contact your aerial contractor.

equipment and that no cables are broken or damaged.
SOUND ONLY COMES FROM SOME OF THE
SPEAKERS
Check that:
all speakers in the system are connected to the P7.
you have configured your pre-amp to include all the speakers in
your system.
you have an appropriate surround sound source selected and
playing through the pre-amp.
for digital sources, check the player is outputting multichannel
data. With some DVD players you are able to select in what
format multi-format encoded discs are outputted, and whether
multichannel data is down mixed to PCM (stereo).
the disc you are playing is a multichannel recording and that the
processor is outputting multichannel audio.
your speaker balance is correct.
all amplifiers are turned on and all channels are working
correctly.
all units are turned on. If the audio is ‘daisy-chained’ from the P7,
make sure that the unit being fed is turned on.

RADIO INTERFERENCE
The P7 is an audio device which has been designed to very high
standards of electromagnetic compatibility.
The unit can radiate RF (radio frequency) energy. In some cases this
can cause interference with FM and AM radio reception. If this is the
case, keep the P7 and its connecting cables as far from the tuner and its
aerials as possible. Connecting the P7 and the tuner to different mains
sockets can also help to reduce interference.
EC COUNTRIES – These products have been designed to comply with
directive 89/336/EEC.

CONSEILS DE SÉCURITÉ IMPORTANTS
Cet appareil a été conçu et fabriqué conformément aux normes de
qualité et de sécurité les plus strictes. Vous devez cependant observer
les précautions suivantes lors de son installation et de son utilisation.
1. Avertissements et consignes
Il est conseillé de lire les consignes de sécurité et d’utilisation avant de
mettre cet appareil en marche. Conservez ce manuel pour pouvoir vous
y référer par la suite et respectez scrupuleusement les avertissements
figurant dans ce manuel ou sur l’appareil lui-même.
2. Eau et humidité
L’installation d’un appareil électrique à proximité d’une source d’eau
présente de sérieux risques. Il ne faut pas utiliser l’appareil à proximité
d’un point d’eau : près d’une baignoire, d’un lavabo, d’un évier, dans une
cave humide ou à côté d’une piscine, etc.
3. Chute d’objets ou infiltration de liquides
Veillez à ne pas laisser tomber d’objets ni faire couler de liquides à
travers l’une des ouvertures du boîtier. Ne posez pas d’objet contenant
du liquide sur l’appareil.
4. Ventilation
Évitez de placer l’appareil sur un lit, un canapé, un tapis ou une surface
similaire instable, ou dans une bibliothèque ou un meuble fermé, ce qui
risquerait d’empêcher une ventilation correcte. Pour permettre une
ventilation appropriée, il est conseillé de prévoir au minimum un espace
de 5 cm de chaque côté et au-dessus de l’appareil.
5. Exposition à la chaleur
Ne placez pas l’appareil près d’une flamme nue ou d’un dispositif
produisant de la chaleur, tel un radiateur, un poêle ou autre appareil (y
compris les amplificateurs).
6. Conditions climatiques
L’appareil est conçu pour fonctionner dans des climats modérés.
7. Étagères et supports
Utilisez uniquement des étagères ou des supports pour appareils
audio. Si l’appareil est posé sur un support mobile, déplacez celui-ci
avec précaution, pour éviter tout risque de chute.
8. Nettoyage
Débranchez l’appareil du secteur avant de le nettoyer.
Pour le nettoyage, utilisez un chiffon doux, humide et non pelucheux.
N’utilisez pas de diluant pour peinture ou de solvant chimique.
L’emploi d’aérosols ou de produits de nettoyage pour meubles est
déconseillé, car le passage d’un chiffon humide risquerait de laisser des
marques blanches indélébiles.
9. Alimentation secteur
Branchez l’appareil uniquement sur une alimentation secteur du type
mentionné dans le manuel d’utilisation ou indiqué sur l’appareil luimême.
10. Protection des cordons secteur
Veillez à ce que les cordons secteur ne se trouvent pas dans un lieu de
passage ou pincés par un objet quelconque. Prêtez particulièrement
attention aux cordons et fiches secteur à leurs points de sortie de
l’appareil.
11. Mise à la terre
Assurez-vous que l’appareil est correctement mis à la terre.
12. Câbles haute tension
Évitez de monter une antenne extérieure à proximité de câbles haute
tension.
13. Périodes de non-utilisation
Si l’appareil possède une fonction de mise en veille, un courant faible
continuera de circuler lorsqu’il est réglé sur ce mode. Débranchez
le cordon secteur de la prise murale si l’appareil doit rester inutilisé
pendant une période prolongée.
14. Odeur suspecte
Arrêtez et débranchez immédiatement l’appareil en cas de fumée ou
d’odeur anormale. Contactez immédiatement votre revendeur.
15. Service
Ne tentez pas d’effectuer d’autres opérations que celles mentionnées
dans ce manuel. Toute autre intervention doit être effectuée par un
personnel qualifié.
16. Entretien par un personnel qualifié
L’appareil doit être entretenu par du personnel qualifié lorsque :
A. la fiche ou le cordon secteur a été endommagé,
B. des objets sont tombés ou du liquide a coulé dans l’appareil,
C. l’appareil a été exposé à la pluie,
D. l’appareil ne semble pas fonctionner normalement ou présente
des altérations dans son fonctionnement,
E. l’appareil est tombé ou le boîtier a été endommagé.
17. Transport de l’unité
Cet amplificateur pèse 31 kg, il faut donc faire extrêmement attention
lorsque vous soulevez ou déplacez l’unité. Nous conseillons de porter
l’unité à deux personnes.
