[. . . ] In addition, by extending the frequency response by two octaves corrects time and phase response within the bandwidth of normal human hearing. Taking these acoustical phase anomalies beyond the range of human hearing adds realism to the soundstage by improving imaging and placement of instruments. 2 AMPLIFIER CHOICE Consult the enclosed product specification sheet as this clearly shows the acceptable power range for amplifier matching to your speakers. The high peak power handling of Tannoy loudspeakers permits responsible use with more powerful amplifiers - please read the Warranty. As with all loudspeaker systems, the power handling is a function of voice coil thermal capacity. [. . . ] It is strongly recommended that you store all the packaging to allow protected transportation in future. WARNING: IT IS IMPERATIVE THAT THE SPIKES AND CONE TIPS ARE FITTED BEFORE THE SPEAKER IS PLACED IN AN UPRIGHT POSITION. FAILURE TO DO SO MAY CAUSE THE SPEAKER (ESPECIALLY TD 12) TO TIP OVER WITH THE RISK OF DAMAGE OR INJURY. The spikes, along with washers and lock nuts, should be fitted loosely into the threaded holes in the base at the rear of the cabinet. The cone tips should then be threaded into the ends of the polished alloy cones at the front of the speaker. Level the rear spikes to the front cones by eye then hand tighten the lock nuts. Spike locating cups are provided and these may be used to protect sensitive floor surfaces. The loudspeaker can now be carefully lifted into an upright position and the packing piece removed from the top panel. Refer to the paragraph headed 'Positioning' for speaker placement advice. The alloy side strips of the speaker are protected with a plastic film; it is recommended that this be left on for protection and should not be removed until the speaker is fully installed. 3 INSTALLATION To avoid potential damage to your loudspeaker, ensure that the amplifier is switched OFF prior to connecting or disconnecting any cables. Before switching on double check that all connections are secure and that polarity is correct. Check that bass and treble information is being reproduced from both speakers - if not, switch off the amplifier and recheck the connections. BI-AMPING (See fig. In this connection option separate power amplifiers are used for bass and treble signals in each loudspeaker. Four mono (or two stereo) amplifiers of the same type are required for a stereo pair of loudspeakers. Ensure that the cable links between the loudspeaker terminals are removed and that correct polarity is maintained throughout. 4 If two stereo amplifiers are used, it is recommended that one amplifier supply bass information to left and right loudspeakers and the other, the treble information. CONNECTION OF EARTH OR `GROUND' LEAD (See figs. 2, 3 and 4) 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. Alternativel y 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. POSITIONING AND FINE-TUNING (See fig. 5) To get best results from your new Tannoy Dimension loudspeakers it is worthwhile spending a little time finding the optimum set-up configuration. Begin by angling the speakers towards your chosen listening position, usually this is on the centre line of the room, so that when seated you can just see the inner side panel of each speaker. The loudspeakers should be located between 1. 5 to 4. 5 metres (5ft to 15ft) apart - with the listening position set slightly further away than the speakers are apart. [. . . ] Wall-mounted loudspeakers should be shelf or bracket mounted 1. 5 to 4. 5 metres (5ft to 15ft) apart with a height mounting height range of 1. 5 to 2 metres (5ft to 7ft). SUBWOOFER TD-SUB As the subwoofer only produces low frequency, therefore monaural information, it is difficult to detect its location by ear. It could as a result be situated anywhere in the room, but optimum performance will be gained by locating the subwoofer between the main stereo pair of speakers. Bass output will increase when placed next to a wall or in a corner so use the subwoofer volume control to balance the output with the rest of the system. Please refer to the manual supplied with the subwoofer for advice on installation and set-up. [. . . ]
