Bi-wiring and bi-amping loudspeakers

BEFOREYOU 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-WIRINGYOUR 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-AMPINGYOUR SYSTEM

The performance of your system can be further enhanced over that	English
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).

Four channels of amplification – for example two P35 stereo amplifiers or four P1 monoblock amplifiers.

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 C30 to the corresponding AUDIO IN sockets of the power amplifier. If using the P1 amplifier, it may be necessary to “daisy- chain” the interconnect cables. See page 11 for more details on doing this.
