AMPLIFIER MATCHING
Consult the Technical Specification section for the acceptable range of amplifier powers. The high peak power handling of Tannoy loudspeakers permits the responsible use with more powerful amplifiers.
As with all loudspeakers, power handling is a function of voice coil thermal capacity. Take care to avoid overdriving any amplifier, as the resulting distortion, or ‘clipping’, can damage the loudspeaker if allowed to continue for an extended period. Generally a higher power amplifier, running free of distortion is safer than a lower power amplifier being driven hard, and will also sound better.
INSTALLATION
If desired, the grille and baffle panel may be painted to match the surrounding décor. Several thin coats of paint will provide a better finish than one overly thick coat.
∙ When painting the baffle, carefully mask off the driver assembly, ensuring that paint does not come into contact with the cone and roll surround.
∙ Paint the grille, leaving the acoustically transparent foam in place on the reverse side. Remove and discard original foam, replacing with the spare sheet supplied. It is important that this is bonded over it’s entire area, using a suitable spray adhesive, to avoid audible resonance.
Using the supplied template, cut the mounting aperture in the ceiling and place the C ring in position, to spread the weight of the clamps on the ceiling. Beware of hidden obstructions and electrical wiring. Always use a good quality speaker cable, and allow enough spare for the loudspeaker to be installed or removed easily. Connect to the two spring terminals, being careful to observe polarity, positive to positive and negative to negative.
Position the loudspeaker in the aperture and tighten the 3 screws which engage the clamping mechanism (Figure 1). WARNING: do not over tighten.
If the speaker has to be removed, loosen the 3 screws, ensuring the clamps are fully retracted.

GRILLE FITTING AND REMOVAL
Before fitting the grille, the HF level control on the baffle should be set to the desired position, according to the acoustics of the environment.
The grille is a tight fit, and should be located by applying even pressure around the circumference. To avoid indentation, do not press the centre of the grille.
If the grille has to be removed, use a firm piece of wire, such as an opened up paper clip, inserted through the mesh. Work around the outside of the grille, to gently prise it off.
