6. d under the TV screen Cables and Connectors Choosing Loudspeaker Cable Specialist audio cable usually offers better performance than general purpose bell or zip wire Choose a cable of suitable diameter cable that is too thin will limit the dynamics of the sound and may impair the bass response Audio cable is polarised with two cores of different colours or often a raised rib or coloured tracer in the case of twin cable Before you purchase your cable I give careful thought to the positioning of your loudspeakers This is especially the case if you are bi wiring your loudspeakers Cable lengths to loudspeaker pairs should be the same for left and right channels in order to equalise the signal transmission Allow some slack in your speaker cables so you can alter their position to best advantage Preparing Loudspeaker Cable Split the twin cores to a depth of about 40mm Carefully strip the insulation from each end leaving about 10mm of bare wire If the cable is stranded lightly twist to gather any loose strands Connecting Screw Terminals All loudspeakers use screw terminals Unscrew the terminal Insert the bare end of the cable into the hole in the base of the terminal Tighten securely When connecting terminals make sure you leave no strands of bare wire that can short across to adjacent terminals As an alternative to bare wire you can use specialist spade connectors Your Wharfedale dealer will be pleased t

15. the optimum listening position A useful rule of thumb is that the listener should be as for from the loudspeakers as they are from each other The speakers should ideally be positioned so that the treble units are roughly at ear level to s seated listener As personal taste plays a large role experiment with different configurations and play a wide range of programmes before finalising the position of your speakers gt 0 7metre r gt pai 122 gt 50 mm 155 159 gt 200 mm Positioning the Centre Loudspeaker The centre channel loudspeaker should be positioned centrally between the loudspeakers close to the television and mounted above or below the screen The loudspeaker should be located on a stable flat surface to avoid any cabinet movement at high sound levels If you mount the unit above the television move it forward so that the front grille sits slightly in front of the screen and the top of the cabinet A custom stand is available for the model which allows the loudspeaker to be positioned under a wall mounted monitor and has an adjustable vertical tilt for optimal dispersion Connecting the Front Loudspeakers Standard Connection Choose a suitable length of twin core speaker cable for each channel and prepare the ends Unscrew each terminal a few turns Connect the red positive terminal of the Left loudspeaker to the corresponding red positive amplifier terminal Connect th
