User manual TANNOY PROFILE 631

[. . . ] His rectifier consisted of two dissimilar metals held in a special electrolyte solution; one was Tantalum and the other an alloy of Lead. So successful was this invention that Guy Fountain founded a British company by the name of Tannoy, a contraction of the words 'Tantalum' and 'Alloy', and this brand name soon became internationally renowned and highly regarded in all aspects of sound reproduction. In combining the best of traditional crafts with the latest production and design skills Tannoy presents the Yorkminster SE loudspeaker. The Yorkminster SE embodies the Tannoy philosophy. Cabinets in selected hardwoods are hand finished and polished to a standard that is unsurpassed. [. . . ] ¥ The negative (minus) terminal on the amplifier left channel (marked - or coloured black) must be connected to the negative HF terminal on the left speaker. ¥ Repeat this connection process for the right speaker. Remember that the positive (+ or red) on the amplifier must be connected to the positive (+ or red) on the speaker and the negative (- or black) to negative. Select a signal source, such as a CD player; switch on the amplifier and slowly turn up the volume control to check that Please note in bi-wire mode that the link leads, which are supplied in the accessory pack, should NOT be fitted. ¥ Be sure that the amplifier is switched OFF and then prepare the two sets of cabling for each 'side' of the system separately. Measure and cut four lengths of cable, two per speaker. Label two of the cable lengths Left LF and Left HF (low frequency and high frequency) then repeat this process for the right pair. ¥ If your amplifier is not equipped with separate output terminals for bass and treble information then, at the amplifier end of the cables, twist the Left LF+ (positive) and the Left HF+ (positive) together. Connect these to the amplifier Left channel positive terminal marked + (plus) or coloured red. Twist the Left LF- (negative) and the HF- (negative) cables together and connect them to the amplifier Left channel negative terminal marked - (minus) or coloured black. At the loudspeaker end connect the cables labelled Left LF+ and Left LF- to the left hand loudspeaker LF terminals, ensuring that you note the polarity markings on the cable sheathing. The high frequency unit does not obstruct the low frequency unit in any way (a unique feature when compared with other so called coaxial systems). Polar dispersion of sound is symmetrical in both horizontal and vertical planes. By careful crossover network design the virtual acoustic sources of the high and low frequency units can be made to occupy the same point on the axis. Therefore the total sound appears to emanate from a single point source located slightly behind the drive unit. This means that the loudspeakers, when fed from a high quality stereo source, can recreate a full and accurate stereo image. Each loudspeaker is fitted with two controls located on the front baffle beneath the detachable grille. These high current switch blocks are labelled ROLL OFF and ENERGY. They can be used to compensate for the varied acoustic characteristics of listening rooms. The controls should be adjusted with the amplifier tone controls in the 'flat' or uncompensated position. Each loudspeaker should be adjusted individually. Fully rotating the amplifier balance control, to select first one loudspeaker and then the other, is the easiest way to do this. It allows the output of the high frequency compression drive unit to be increased 6 or decreased from the linear or 'flat' position over a frequency band from approximately 1 kHz to 20kHz. 7 Yorkminster The Low Frequency Section The low frequency section of the Dual Concentric" driver has exceptional power handling and dynamic range. [. . . ] A very robust, high quality, precision pressure die-cast chassis locates the whole magnet assembly and positions the moving parts with high accuracy. This provides long-term reliability and yet does not interfere with the acoustic radiation from the individual sections. 8 and consistent. This provides the correct intensity information to recreate the original sound stage. 9 Yorkminster Care of the Cabinet The cabinet is constructed from carefully selected solid hardwood and veneers that have been hand finished to exacting standards. The wood should only be cleaned with a dry cloth or with a light application of quality non-silicone furniture polish, taking care not to get polish on the grille cloth. Warranty and Service Your Tannoy Prestige loudspeakers will operate for many years without trouble provided that simple precautions are followed. Tannoy loudspeakers are warranted against manufacturing defects in material or craftsmanship over a period of 5 years In common with all solid wood furniture, exposure to extremes of heat, cold and varying humidity will cause the wood to ease slightly.
