User manual TANNOY DEFINITION

[. . . ] Our policy commits us to incorporating improvements to our products through continuous research and development. Please confirm current specifications for critical applications with your supplier. 02_ DEFINITION MANUAL INTRODUCTION Thank you for selecting Tannoy loudspeakers developed in the UK by our dedicated team of design engineers. They are the choice of discriminating music lovers the world over. Musical excellence is designed into our loudspeakers from the start. [. . . ] This, if done for any extended period, will cause damage to the speakers. Generally an amplifier of higher power that is running hard, but free of distortion, will do less damage to the loudspeaker than a lower power amplifier continually clipping. Remember also that a high powered amplifier running at less than 90% of output power generally sounds a great deal better than a lower powered example struggling to achieve 100%. An amplifier with insufficient drive capability will not allow the full performance of the loudspeakers to be realised. CABLE CHOICE Always use the best quality of cable available within your budget. High quality audio signals passing from the amplifier to the loudspeaker are unusual in their demands on the cable. Wide dynamic range and frequency bandwidth information has to coexist with the ability to transmit peak currents of at least 10amps, without incurring any loss or signal impairment. This explains why the sound quality of the information reproduced by the loudspeakers is so dependant on the physical properties of the cables connecting them to the amplifier. We would recommend that you always keep the cable runs the same length for left and right speakers. Remember, cable construction can affect the sound quality so be prepared to experiment to find a cable that suits your ear and audio system. UNPACKING To unpack the loudspeakers from their boxes remove tape from the top then fold the flaps right back before inverting the carton and contents. Lift the carton clear of the contents then remove all inner packaging. It is strongly recommended that you store all the packaging to allow protected transportation in future. (See fig. 1) TERMINAL PANEL An exclusive five way terminal panel has been designed for the Definition range to optimise performance further by take advantage of the driver earthing facility. Use a shielded or screened loudspeaker cable; connecting the screening termination 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. (See fig. 2) FLOOR STANDING MODELS Definition floor-standing models perform best with carpet piercing spikes fitted. These are supplied, along with lock nuts, and should be inserted into the threaded holes in the base of the cabinet. Level the speaker and then tighten the lock nuts firmly but without using undue force. Spike locating cups are provided in the accessory pack and these may be used to protect sensitive floor surfaces. Warning: Ensure that the spikes are levelled and that the lock nuts are tightened firmly. The spikes should be pushed through the carpet to locate into the flooring surface by applying pressure to the top of the cabinet. If using on a sensitive floor surface place the protective cups under the levelled spikes. Failure to do so could render the speaker unsteady and result in damage or injury should it be knocked over. STAND MOUNTING MODELS Stand mounting or bookshelf speakers should be located securely on stands or a shelf in an appropriate position to place the Dual ConcentricTM driver high frequency unit roughly at ear height when seated in the chosen listening position. Positioning recommendations for stand-mounted speakers can be found under the section entitled Positioning and fine-tuning. [. . . ] 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. 06_ DEFINITION MANUAL TECHNICAL SPECIFICATIONS DC8 PERFORMANCE Recommended amplifier power (Watts RMS) Continuous power handling (Watts RMS) Peak power handling (Watts) Sensitivity (2. 83 Volts @ 1m) Nominal Impedance (Ohms) Frequency response (-6dB) Dispersion (degrees conical) DRIVE UNITS Dual ConcentricTM high frequency Dual ConcentricTM low frequency 25mm (1") Titanium dome with Tulip WaveGuideTM 200mm (8") treated paper pulp cone with rubber surround. 44mm (1. 75") edge wound voice coil Bass Driver 25mm (1") Titanium dome with Tulip WaveGuideTM 200mm (8") treated paper pulp cone with rubber surround. 44mm (1. 75") edge wound voice coil 200mm (8") treated paper pulp cone with rubber surround. 44mm (1. 75") edge wound voice coil 25mm (1") Titanium dome with Tulip WaveGuideTM 250mm (10") treated paper pulp cone with twin roll impregnated fabric surround.
