Installation: P35 power amplier
CONNECTING TO OTHER EQUIPMENT
Follow the installation instructions for the integrated amplifier on
pages 5–6.
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.

Optional Third Channel Module
– provides a third 90W channel

multi-channel audio use.
REMOTE SWITCHING
By making a connection from the REMOTE IN socket of the P35 power
amplifier to the TRIG OUT socket of the A32 integrated amplifier, you
can use the A32 to switch the power amplifier on and off. If configured
in this way, the front panel POWER button of the A32 (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
A32 by ‘daisy chaining’ from TRIG OUT of one P35 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
P35/3.
The module offers extra loudspeaker terminals together with a third
set of AUDIO IN and OUT phono sockets and converts the P35 into
a 3 x 90W (RMS per channel into 8Ω) amplifier suitable for Home
Cinema or multi-channel audio use.
Contact your Arcam dealer for further details.

Using your P35 power amplier
POWER (AND POWER INDICATOR LIGHT)
Switches the unit on and off. The light indicates the status of the
amplifier.
When you switch your amplifier on, the light glows amber for a few
seconds, during which time the speakers are disconnected. The light
changes to green when the amplifier is ready for use. A red light
means the amplifier is in standby mode.
The light may flash if a fault has occurred. You should unplug the
amplifier and leave it for a few minutes before reconnecting. If the
fault cannot be cleared, unplug your amplifier and contact your Arcam
dealer.

NOTE: If both lights are out the amplifier will appear not to work,
as all speakers are switched off. If both are on, and low impedance
speakers are connected, overloads are more likely.
SP1 AND SP2
These buttons allow you to select and deselect the main (SP1) and
secondary (SP2) sets of speakers attached to your amplifier. An
indicator light shows which set of speakers are currently selected.

Bi-wiring and bi-amping loudspeakers
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 LF (Low Frequency).
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). Or, a suitably terminated cable set (a
loom, probably prepared by your dealer and capable of being used for
bi-wiring in one length).
How to bi-wire loudspeakers
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.
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.
Connect the integrated amplifier to the high frequency (HF) terminals
and connect the power amplifier 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 amplifiers – one of these would be the A32 and the other an
Arcam power amplifier (e.g. P35).
Loudspeaker cables – two pairs of cables per loudspeaker or a suitably
terminated cable set (a loom, probably prepared by your dealer and
capable of being used for bi-amping in one length).
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
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 the interconnect cables to connect the PRE OUT sockets of
the A32 to the corresponding AUDIO IN sockets of the power
amplifier.

Service information
Before returning your amplifier 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 amplifier will operate.
The power indicator on the front panel flashes and the protection
system temporarily removes the power to the speakers. The system
resets itself as the heatsink cools down.
Note that because of the high output voltage from a CD player, it is
possible to drive the A32 at full power even though the volume is not
set at maximum.
AMPLIFIER DOES NOT SWITCH BACK ON
The A32 and P35 amplifiers 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.
