User manual TANNOY WESTMINSTER ROYAL

[. . . ] OWNER'S MANUAL Estd. 1926 In combining the best of traditional crafts and the latest production and design skills Tannoy presents the Westminster Royal SE loudspeaker. The Westminster Royal SE embodies the Tannoy philosophy. Cabinets in selected hardwoods are hand finished and polished to a standard that is unsurpassed. The Westminster Royal SE offers a compound horn loaded enclosure driven by classic Dual ConcentricTM technology. [. . . ] Insert the key provided into the lock at the bottom of the main grille assembly and turn anti-clockwise to release. Pull the bottom of the grille away from the cabinet; the grille will drop down from its upper location. Take care not to damage the solid walnut lower part of the cabinet. To replace the grille engage the top of the grille into the slot in the cabinet and push the grill into the recess. Apply slight pressure to the bottom whilst turning the key clockwise to engage the lock. The side grilles are service removable only, by pulling them away from locating dowels mounted on the cabinet. Do not use excessive force and take care not to damage the solid walnut mouldings. Loudspeaker System Adjustment 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. This is most easily done by rotating the amplifier balance control to select first one loudspeaker and then the other. It allows the output of the high frequency compression drive unit to be increased or decreased from the linear or 'flat' position over a frequency band from approximately 1kHz to 20kHz. The ROLL OFF control has five positions (+2, level, -2, -4 and -6dB per octave) and provides adjustment at extreme high frequencies from 5kHz to 20kHz. The ENERGY control has a shelving effect over the 1kHz to 20kHz frequency band whereas the ROLL OFF control increases or decreases the slope of the extreme high frequency response hinging about 5kHz. The flattest, most linear response from the loudspeaker will be obtained with both controls set at the LEVEL position, and this position should be used for initial listening tests. If the overall high frequency sound quality seems too prominent the -1. 5 or -3 positions for the ENERGY control should be tried. If the sound appears subdued in the treble region +1. 5 or +3 settings may be preferred. Once the ENERGY control setting has been established the ROLL OFF control can be adjusted to reduce or slightly increase the extreme high frequency content if necessary. Remember the changes that can be made by moving either control from one position to another are subtle. They may not easily be heard if the programme material has very little content in the frequency band under consideration. Choose a well balanced piece of music with a full spectrum of sound. [. . . ] Work the wax into the wood covering a small area at a time. In common with all solid wood furniture, exposure to extremes of heat, cold and varying humidity will cause the wood to ease slightly. Therefore it is recommended that the loudspeaker is protected from environmental extremes to guard against any such occurrence. Faultfinding Tannoy loudspeakers are designed and manufactured to be reliable. When a fault occurs in a hi-fi system the effect is always heard through the loudspeakers although they may not be the source of the fault. [. . . ]
