Connection In Single Wire Mode; Connection In Bi Wire Mode - Tannoy revolution Owner's Manual

CONNECTION IN SINGLE WIRE MODE

The terminal panels have captive link bars fitted as standard to link the positive and negative HF and LF terminals
respectively. These must be removed to bi-wire the speakers - see section entitled Connection in Bi-wire mode.
(See fig. 2)
For optimum performance in single wire mode, loudspeaker cable connections from the amplifier should be made
to the high frequency (HF) terminals of the loudspeaker:
The positive (plus) terminal on the amplifier left channel (marked + 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. (See fig. 3)
CONNECTION IN BI-WIRE MODE
Please note in bi-wire mode that the link bars must be removed. Unscrew the knurled nuts on both the positive
and negative HF and LF terminals and remove the link bar and then replace the colour coded nuts, as they will be
required to clamp the bi-wire cables in place. Retain the link bars in a safe place for possible future use.
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 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. (See fig. 4)
