WHARFEDALE OPUS 3 (01) PDF Document

Please read the following notes carefully to install your loudspeakers correctly and safely. Switch off the amplifier and all sources before making connections to your sound system. When you switch on the system or change sources, set the volume control to minimum and turn up the level gradually. The position of your Volume Control is not a reliable guide as to the maximum capabilities of your system. Playing the system with extreme settings of volume and tone controls may damage the amplifier and loudspeakers. Do not connect loudspeaker terminals to the mains supply. Ensure that your loudspeakers are correctly wired and are in phase. Do not subject your loudspeakers to excessive cold, heat, or sunlight. Do not place heavy objects on top of loudspeaker cabinets. If you play them with the grilles removed, be careful to protect the drive units from children and pets. Do not use makeshift stands. Always fit a manufacturer approved stand using the instructions and the fixings provided. Do not attempt to dismantle the loudspeaker. There are no user serviceable parts inside and you will invalidate the warranty. Site your loudspeaker at least 0.5m away from TV sets and magnetic storage media.

The WHARFEDALE OPUS 3 speakers are heavy, so take care when removing them from their packaging. Always lift the speakers out by their sides. Carefully remove each loudspeaker from its packing carton. Be especially careful when removing the polythene bag. The speakers come with the plinth complete and already fitted. The carton top says, Open other end. So you should open the bottom, remove the polystyrene, open the bag containing the speaker, tape the carton flaps back, turn over the carton with the loudspeaker still inside, and lift the carton off, leaving the loudspeaker standing on the floor. Be careful not to damage soft floor surfaces with the spikes.

Your floor standing WHARFEDALE OPUS 3 speakers are delivered with the plinth and spikes already fitted. Levelling or seating the speaker is best achieved by adjusting either of the rear spikes until the speaker is stable without rocking. Release the top knob on the underside, turn the spike out and down to level, then re-lock the top knob. For wood or soft floors, 8 metal spike seats and self-adhesive pads are provided for use as required. A set of extra long spikes for deep carpets is provided and may be used as required.

Specialist audio cable usually offers better performance than general purpose bell or zip wire. Choose a cable of suitable diameter, as 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 of coloured tracer in the case of twin 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.

Unscrew the terminal. Thread the bored end of each cable through the hole in the bottom of the terminal post. Ensure that there are no loose strands which may touch adjacent terminals. Retighten the terminal securely. When connecting loudspeakers, the cables to left and right channels should be of equal length, regardless of the distance of the speakers from the amplifier. This applies to front and rear channels.

Place the speakers so that you are the same distance from each. The distance between the speakers should be the same as between you and the speakers. For best results, the speakers should be at least 20cm in front of a wall and at least 70cm from any corner. Angle speakers inward by 5 degrees to 30 degrees for a clearer, more tuneful mid range. If the loudspeakers are placed too close to the walls, the bass will increase but may be boomy and indistinct. If the loudspeakers are placed further away from the walls, the inward angle may be increased by up to 40%, although this may restrict the width of the optimum listening position. Experiment with different configurations before finalising the position.

Using separate cables for treble, mid, and bass units in a Tri or Bi-wiring configuration reduces intermodulation effects and improves headroom and clarity. To Bi-wire, you will need to install two lengths of twin core cable between the amplifier and each loudspeaker. Unscrew each terminal a few turns and remove the metal tri-link straps. Use the bi-link straps to connect the treble and mid-range terminals. Connect the cables between the amplifier and the loudspeakers as indicated and re-tighten all the terminals securely.

Remove marks from the cabinet and polish it with a soft, slightly damp cloth. Avoid getting any liquid behind the grille.
