CONNECTION IN BI-WIRE MODE
LINKS
REMOVED
Please note in bi-wire mode that the link plates should first be removed.
• Be sure that the amplifier is switched OFF and then prepare the two sets of cabling for each 'side' of the system separately. Measure
and cut four lengths of cable, two per speaker. Label two of the cable lengths Left LF and Left HF (low frequency and high frequency)
then repeat this process for the right pair.
• If your amplifier is not equipped with separate output terminals for bass and treble information then, at the amplifier end of the
cables, twist the Left LF+ (positive) and the Left HF+ (positive) together. Connect these to the amplifier Left channel positive
terminal marked + (plus) or coloured red.
Twist the Left LF- (negative) and the HF- (negative) cables together and connect them to the amplifier Left channel negative terminal
marked - (minus) or coloured black. At the loudspeaker end connect the cables labeled Left LF+ and Left LF- to the left hand
loudspeaker LF terminals, ensuring that you note the polarity markings on the cable sheathing.
Then proceed to connect the Left HF+ and Left HF- to the HF terminals on the same loudspeaker.
• Repeat this process to connect the right hand loudspeaker to the amplifier right channel output, once again ensuring that polarity
is correct throughout.
Switch the amplifier on with the volume control set at its lowest setting. Select a favourite source and slowly turn up the volume
to a low level. Check that bass and treble information is being reproduced from both speakers- if not, switch off the amplifier and
recheck the connections.

Bi-Amping extends the principle of bi-wiring one stage further. In this connection option separate power amplifiers are used for bass
and treble signals in each loudspeaker. Four mono (or two stereo) amplifiers of the same type are required for a stereo pair of loudspeakers.
Ensure that the cable links between the loudspeaker terminals are removed or amplifier damage may result and that correct polarity is
maintained throughout.
If two stereo amplifiers are used, it is recommended that one amplifier supply bass information to left and right loudspeakers and the
other, the treble information.
Avoid potential damage to your amplifier - ensure that all connections are secure and the polarity is correct in all wiring.
CONNECTION OF EARTH OR 'GROUND' LEAD
To optimise performance further, use a shielded or screened loudspeaker cable. The screening termination should be connected to the
earth or ground (green) terminal on the loudspeaker and to the ground or earth connection on the amplifier.
Alternatively if you are not using a screened loudspeaker cable but wish to utilise the earthing facility, run a single cable between the
earth terminal on the loudspeaker and the amplifier, such as the Tannoy TLC cable.
