Placing the unit
<Place the amplier on a level, rm surface,
avoiding direct sunlight and sources of heat or
damp.
<Do not place the P429 on top of a power
amplier or other source of heat.
<Do not place the amplier in an enclosed space
such as a bookcase or closed cabinet unless
there is good provision for ventilation. The
P429 is designed to run warm during normal
operation.
<Do not place any other component or item on
top of the amplier as this may obstruct airow
around the heatsink, causing the amplier to
run hot. (The unit placed on top of the amplier
would become hot, too.)
<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.
Power
The amplier is supplied with a moulded mains
plug already tted to the lead. Check that the plug
supplied ts your supply – should you require a new
mains lead, please contact your Arcam dealer.
If your mains supply voltage or mains plug is dierent,
please contact your Arcam dealer immediately
Push the IEC plug end of the power cable into the
socket on the back of the amplier, making sure that
it is pushed in rmly. Plug the other end of the cable
into your mains socket and, if necessary, switch the
socket on.
Interconnect cables
We recommend the use of high-quality screened
cables that are designed for the particular application.
Other cables will have dierent 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.
Arcam’s P429 power amplier provides class leading
sound quality for the best possible reproduction of
your music.
Drawing on the many years of amplier design
experience at Arcam, this product uses the best
quality components and engineering practice to
produce a product that will give many years of
musical pleasure and reliable service.
With a class G amplier, toroidal based power supply,
acoustically damped chassis, parallel transistor output
stages and exceptionally low levels of distortion and
noise, the P429 is 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 P429 is designed to produce a level of
performance that will truly bring music to life. The
amplier has a multitude of applications, such as
bi-amping a two channel audio/video system, adding
extra zones to an existing system or adding height
channels to an audio/video system.

drive four independent speakers. As an example,
please refer to “Single wiring” on page E-10
<In DM (Dual Mono) mode, CH1 and CH2 are fed
from the CH1 input only, while CH2 is not used.
Similarly, CH3 and CH4 are fed from CH3 only,
while CH4 is not used. This would be used to
drive two independent speakers in a bi-amped
conguration. An example of this is shown in
“Dual mono / Bi-Amping” on page E-11
<In BR (Bridged) mode, CH1 and CH2 are bridged
together and are fed from CH1 only, while CH2

loudspeakers
Single wiring
Single wiring is the conventional wiring method
of connecting a single cable per channel and each
speaker; this is the easiest technique.
If each speaker has more than one pair of connecting
terminals, use the terminals labelled HF or ‘High
Frequency’.
In this conguration, each P429 input (labelled IN1,
IN2, IN3 and IN4) must be connected to each of
the four preamplier outputs of your audio/video
receiver, such as the Arcam AVR550/850.
WARNING: If your speakers support bi-wiring, there will be a
strip of conductive metal connecting the low-frequency (LF)
terminals to the high-frequency (HF) terminals; this MUST NOT
BE REMOVED in a single-wired system.
Notes on making speaker connections
<Do not make any connections to any amplier while it is switched on. We recommend that your
amplier is completely disconnected from the mains supply before starting.
<Before switching your amplier on for the rst time after connecting to speakers, please check all
connections thoroughly. Ensure that bare wires or cables are not touching each other or the amplier’s
chassis (which could cause short circuits), and that you have connected positive (+) to positive and
negative (–) to negative. Be sure to check the wiring for both the amplier and the speaker.
<After making connections: switch the amplier on, select a source signal, then gradually increase the
volume to the required listening level.
<If you are unsure as to how your system should be connected, please contact your Arcam dealer who
will be happy to help you.
Connecting
loudspeakers
There are many dierent ways of connecting your
loudspeakers to your P429 and the following
section describes how to connect and congure the
loudspeakers and amplier for the most common
congurations.

Dual mono / Bi-Amping
Dual mono requires the use of two channels of the
P429 for each speaker, as shown in the diagram
below.
In this setup, only one interconnect is required for
each pair of channels. The Land Routput of the two
channels of your audio/video device (such as the
Arcam 550/850) should be connected to the IN1 and
IN3 input of the P429, respectively.
WARNING: the strip of metal on the speakers connecting
the low frequency (LF) terminals to the high frequency (HF)
terminals MUST BE REMOVED. Failure to do so will result
in damage to both ampliers, which will not normally be

Bridged mode
In bridged mode, only the positive (red) speaker
outputs of each P429 channel are active. No
connections should be made to the negative (black)
speaker terminals.
WARNING: Do not make any connections to the other speaker
terminals, doing so will severely damage your amplier.
If each speaker has more than one pair of connecting
terminals, use the terminals labelled HF or ‘High
Frequency’.
In this setup, only one interconnect is required for
each pair of channels. The Land Routput of the two
height channels of your audio/video device (such as
the Arcam AVR550/850) should be connected to the
IN1 and IN3 input of the P429, respectively.
WARNING: If your speakers support bi-wiring, there will be a
strip of conductive metal connecting the low-frequency (LF)
terminals to the high-frequency (HF) terminals; this MUST NOT
BE REMOVED in a bridged mode system.

troubleshooting
Sound cuts-out unexpectedly
The P429 may enter a protection mode, depending
on the fault being detected. The front panel LED will
indicate the fault type, according to the following list:
<ALTERNATE RED/GREEN: The internal
temperature of the unit reached an unsafe level.
Allow the P429 to cool o.
<FLASHING RED: The P429 amplier detected a
speaker short circuit. Should this happen, please
inspect all the speaker cables to make sure none
of them are shorted together. This fault is very
common when bare wires are being used to make
speaker connections.
<FLASHING ORANGE: The amplier detected a
DC oset.
Following any of the faults described above, the
amplier will turn itself o and power to the speakers
will be removed. To continue using the P429, the fault
must be removed and the unit must be turned OFF
then back ON.
If you are having trouble with your amplier, check
the following items.
No sound
Check the following:
<The P429 power amplier is correctly plugged in
and switched on
<Your audio/video source (e.g. preamplier) is
correctly connected, the correct input is selected
and it is not muted
<The P429 is not in protection mode, as described
in the next section.
