• 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.
BI-AMPING
(See fig. 5)
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.
CONNECTION OF EARTH OR 'GROUND' LEAD
(See figs. 4, 5 and 6)
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
It is essential that the coupling link cables between the loudspeaker terminals be removed.
Avoid potential damage to your amplifier - ensure that all connections are secure and the
polarity is correct in all wiring.
POSITIONING AND FINE-TUNING
(See fig. 9)
To get best results from your new Tannoy Eyris 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.
With the speaker in its listening position, rock the loudspeaker gently from side to side
so that the spikes in the metal stabilising feet find their way through the weave of the
carpet and on to the solid surface below. Once fine adjustments have been made to the
spikes, to level the loudspeaker and ensure stability, tighten the lock nuts firmly but without
using undue force.
