Please note in Bi-wire mode that the link cables should not be used. (See fig. 4)
• If not using specially designed bi-wire cable, 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.
BI-AMPInG
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 treble information. (See fig. 5)

Use of a shielded or screened loudspeaker cable will offer further performance advantages when used with the five-way
terminal panel. The screening termination should be connected to the earth or ground (white) 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 or ‘ground’ (white) terminal on the loudspeaker to the
earth (ground) connection on the amplifier.
Avoid potential damage to your amplifier - ensure that all connections are secure and the polarity is correct in all wiring.

To get best results from your new Tannoy Definition DC10A loudspeakers, it is worthwhile spending a little time finding the
optimum set-up configuration.
Begin by angling the speakers towards your chosen listening position, usually this is on the centre line of the room, so that
when seated you can just see the inner side panel of each speaker. The front of the loudspeaker should not be obstructed
in any way. The loudspeakers should be located between 1.5 to 4.5 metres (5ft to 15ft) apart - with the listening position
set slightly further away than the speakers are apart. Avoid positioning the loudspeakers in corners of the room, as this will
have a negative effect on performance. Ideally, maintain a distance of at least 0.5 metres (20 inches) from the rear wall, and
1 metre (39 inches) from the side. (See fig. 6).
