Tannoy Definition - Bi-Amping; Connection of Earth or Ground Lead; Positioning and Fine Tuning

06_ DEFINITION MANUAL
BI-AMPING
Bi-Amping extends the principle of bi-wiring one stage further. In this connection option separate power ampliers
are used for bass and treble signals in each loudspeaker. Four mono (or two stereo) ampliers 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 ampliers are used, it is recommended that one amplier supply bass information to left and right
loudspeakers and the other, the treble information. (See g.6)
CONNECTION OF EARTH OR ‘GROUND’ LEAD
Use of a shielded or screened loudspeaker cable will offer further performance advantages when used with the ve-
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 amplier. 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 amplier.
POSITIONING AND FINE TUNING
To get best results from your new Tannoy Denition loudspeakers it is worthwhile spending a little time nding the
optimum set-up conguration.
Begin by angling the speakers towards your chosen listening position, usually this is on the centre line of the room.
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.
