To avoid potential damage to your loudspeaker, ensure that the amplifier is switched OFF prior to connecting or disconnecting
any cables. Before switching on double check that all connections are secure and that polarity is correct.
WARNING: SEE THE SECTION ON SCREENING IF POSITIONING NEAR TO A TELEVISION SCREEN.
INSTALLATION
(See fig. 2)
Connect the pair of link cables supplied in the accessory kit to each loudspeaker terminal panel as follows:
• Starting with the red (positive) lead, loosen the locking pin which passes through the plug by turning the plastic head of
the locking pin one full anti-clockwise rotation.
• The 'unlocked' plug can now be inserted into the red (positive) low frequency (LF) terminal on the loudspeaker.
• Tighten the plug by turning the locking pin clockwise until finger-tight.
• The spade connection at the other end of the lead should be connected to the red (positive) high frequency (HF) terminal
on the loudspeaker. To do this, loosen the terminal nut sufficiently to allow insertion of the spade connector and then
re-tighten the terminal nut finger-tight.
• Repeat this operation for the black (negative) HF and LF terminals
• Repeat the whole operation for the other loudspeaker
For optimum performance in single wire mode, loudspeaker cable connections from the amplifier should now be made to
the high frequency (HF) terminals of the loudspeaker:
• The positive (plus) terminal on the amplifier left channel ( or coloured red) must be connected to the positive
HF terminal on the left speaker. The left speaker is the one on the left as you look at the stereo pair from your listening
position.
• The negative (minus) terminal on the amplifier left channel (marked - or coloured black) must be connected to the negative
HF terminal on the left speaker.
• Repeat this connection process for the right speaker. Remember that the positive (+ or red) on the amplifier must be
connected to the positive (+ or red) on the speaker and the negative (- or black) to negative.
Select a signal source, such as a CD player; switch on the amplifier and slowly turn up the volume control to check that both
loudspeakers are reproducing bass and treble information.
CONNECTION IN SINGLE WIRE MODE
(See fig. 3)
Please note in Bi-wire mode that the link leads, which are supplied in the accessory pack, should NOT be fitted.
• 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 (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 labelled 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.
CONNECTION IN BI-WIRE MODE
(See fig. 4)
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 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.
