[. . . ] OWNER'S MANUAL Yorkminster Estd. 1926 The Yorkminster SE Yorkminster Tannoy - A Short History In the early days of broadcasting radio sets needed both low and high voltage DC power and this had to be supplied by batteries. The lead acid batteries commonly used in the radio equipment of the time therefore needed regular recharging. Fountain perfected a new type of electrical rectifier with the aim of designing a charger more suitable for use in the home. [. . . ] Then proceed to connect the Left HF+ and Left HF- to the HF terminals on the same loudspeaker. ¥ Repeat this process to connect the right hand loudspeaker to the amplifier right channel output, once again ensuring that polarity is correct throughout. ¥ Switch the amplifier on with the volume control set at its lowest setting. 2, 3 and 4) 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. The correct setting will be found when the loudspeakers are no longer evident and only the musical performance is heard. To optimise performance further, use a shielded or screened loudspeaker cable. The screening termination should be connected 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. It is essential that the coupling link cables between the loudspeaker terminals be removed. Avoid potential damage to your amplifier - ensure that all connections are secure and the polarity is correct in all wiring. Running in Like all loudspeakers, the drive unit in your Tannoy Yorkminster requires a while to reach optimum performance, as the stresses in the materials relax - especially in the suspension system. For this reason, it is beneficial to run the system at Grille Removal Special acoustically transparent cloth is used in the grilles. However, for ultimate fidelity the enthusiast will find it is best to use these loudspeakers with their grilles removed during listening. The front grille is removable for access to the front panel controls. Unscrew the grille removal knob from the rear of the cabinet, and screw into the hole in the bottom of the grille. Using this knob, 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 wooden 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, until the grille clicks in place. fairly high levels at normal room temperature, for approximately 20 hours to achieve best results. Tannoy Dual Concentric " Drive Unit One of the unique advantages of the Tannoy Dual Concentric" principle is that the low and high frequency sound radiation is generated on the same axis. The high frequency unit is mounted behind, and concentrically with, the low frequency unit. High frequency sound radiates from the centre of the low frequency unit through a carefully designed high frequency exponential horn. Low and high frequencies are therefore fully integrated at source. It is this feature that gives the Dual Concentric" driver such unique sound reproduction qualities. Loudspeaker System Adjustment (See fig. [. . . ] Therefore it is recommended that the loudspeaker is protected from environmental extremes to guard against any such occurrence. Any wood will change colour when subjected to the UV content of ambient light. Light veneer will darken appreciably to a rich natural patina, while dark wood may lighten. Tannoy Ltd or its authorised Distributor or Service Agent will make the determination of the cause of failure based on physical inspection of the failed parts. [. . . ]
