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.

speaker cables. This avoids signal distortions arising from the

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 amplifier to the high frequency (HF) terminals and
connect the power amplifier to the low frequency (LF) terminals.

You will need:

Two amplifiers – one of these would be the A80 and the other
an Arcam power amplifier (e.g. P80).

a suitably terminated cable set (a loom, probably prepared by
your dealer and capable of being used for bi-amping in one

Interconnect cables – one pair of high quality interconnect
cables.
