Bi-Amping; Connection Of Earth Of Ground Lead; Positioning And Fine-Tuning; Grilles - Tannoy Definition Owner's Manual

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.
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 (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 or
'ground' (green) 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. (Method illustrated on all terminal panel sketches)
To get best results from your new Tannoy Definition 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 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
.
The main Definition grille has been designed to provide acoustic transparency. However, for ultimate fidelity the
enthusiast will appreciate the slight improvement in clarity and detail that is achieved by removing the grilles
during listening.
The cabinets should only be cleaned with a dry cloth or with a light application of quality non-silicone
furniture polish.
