Bi-wiring and bi-amping loudspeakers

Before you start

Bi-amping your system

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.

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 AVR200 to the high frequency (HF) terminals and connect your 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 AVR200 and the other an Arcam power ampliﬁer (e.g. an P75 or P85).

Loudspeaker cables – one pair 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.

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.
