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, the treble information. (See fig. 5)

POSITIONING AND FINE-TUNING

To get best results from your new Tannoy Revolution 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. For optimum

performance, we would recommend ideally maintaining a distance of at least 0.5 metres (20 inches) from the rear

wall, and 1 metre (39 inches) from the side. However, there is no absolute right or wrong as it is much down to

personal preference and the differing sizes and acoustic properties of the listening environment. The speakers

may be located close to the rear wall, in which case bass will be increased at the expense of definition, and stereo

soundstaging will be compromised. (See fig. 6)

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.

GRILLES

The Revolution 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.

CARE OF CABINET

The cabinets should only be cleaned with a dry cloth or with a light application of quality non-silicone furniture polish
