User manual TANNOY TD12

[. . . ] We are confident that you will continue to enjoy your new Tannoy Dimension loudspeakers for many years to come. WIDEBAND TECHNOLOGY A Tannoy SuperTweeter is incorporated into the design of all Dimension models, not only to resolve fine detail of high frequency information but also to effectively enhance the listening experience throughout the whole frequency range. The Dimension SuperTweeter creates an increased immediacy, airiness and impact making music sound more natural and true to life. Music contains transient information and rich harmonics beyond the range of human hearing for pure tones. Operating between the roll-off point of the Dual ConcentricTM high frequency unit and 54kHz, the Dimension SuperTweeter will accurately reproduce the leading edge of individual notes allowing the listener to experience the entire bandwidth information of instruments. [. . . ] Before switching on double check that all connections are secure and that polarity is correct. WARNING: SEE THE SECTION ON SCREENING IF POSITIONING NEAR TO A TELEVISION SCREEN. CONNECTION IN SINGLE WIRE MODE (See fig. 2) Connect the pair of link cables supplied in the accessory kit to each loudspeaker terminal panel as follows: · Starting with the red (positive) lead, loosen the locking pin which passes through the plug by turning the plastic head of the locking pin one full anti-clockwise rotation. · The 'unlocked' plug can now be inserted into the red (positive) low frequency (LF) terminal on the loudspeaker. · Tighten the plug by turning the locking pin clockwise until finger-tight. · The spade connection at the other end of the lead should be connected to the red (positive) high frequency (HF) terminal on the loudspeaker. To do this, loosen the terminal nut sufficiently to allow insertion of the spade connector and then re-tighten the terminal nut finger-tight. · Repeat this operation for the black (negative) HF and LF terminals · Repeat the whole operation for the other loudspeaker For optimum performance in single wire mode, loudspeaker cable connections from the amplifier should now be made to the high frequency (HF) terminals of the loudspeaker: · The positive (plus) terminal on the amplifier left channel (marked + or coloured red) must be connected to the positive HF terminal on the left speaker. The left speaker is the one on the left as you look at the stereo pair from your listening position. · 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. 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 both loudspeakers are reproducing bass and treble information. CONNECTION IN BI-WIRE MODE (See fig. 3) 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. 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. 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.
