Bi-wiring and bi-amping loudspeakers

Bi-wiring improves the sound of your system as it divides the high and low frequency signal currents into separate speaker cables. 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. This is called “bi-amping”.

Before you start – important information!

1.Ensure that the volume control is set to minimum before starting these procedures.

2.Do not make any connections to your AVR250 while it is switched on or connected to the mains supply.

3.After connecting the loudspeakers, but before switching on the AVR250, please check all connections thoroughly, making sure bare wires or cables are not touching the AVR250 in the wrong places (which could cause short circuits) and that you have connected positive (+) to positive and negative (–) to negative.

Bi-wiring your loudspeakers

Bi-wiring avoids signal distortions arising from the high and low frequency currents interacting with one another within a single cable, as occurs in conventionally wired systems.

You will need:

Speakers – with four input terminals each: the terminals will be marked HF (High Frequency

+and –) and LF (Low Frequency + and –). Loudspeaker cables – two pairs of cables per loudspeaker.

How to bi-wire loudspeakers

1.Remove the terminal links on the rear of your loudspeakers.

NOTE: If you do not remove the shorting links from the speaker terminals, the speakers will still be single-wired!

2.Connect the cables as shown in the diagram, ensuring correct polarity at all times.
