OPUS 1, 2 & 3 SPIKES

Your floor standing Opus speakers are delivered with the plinth and spikes already fitted. Levelling/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 spike out and down to level. Re-lock 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 are provided and may be used as required.

WARNING: Opus speakers are heavy and the spikes can penetrate softer floors materials over extended periods.

CONNECTIONS AND TERMINALS

Choosing and Preparing Cables

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 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.

Crossover Networks

OPUS front and centre loudspeakers use a specially designed bi-wireable crossover panel with six terminal binding posts. Please follow the drawing care- fully to see the correct orientation of the loudspeaker terminals. The upper ter- minals connect to the treble unit, the middle pair to the mid-range and the lower pair to the bass units. As supplied, the treble terminal pair is connected to the mid-range pair and bass terminal pair via removable metal straps. These should be left in place for standard single cable installations.

The OPUS surround uses a conventional twin terminal crossover panel.

Connecting Loudspeaker Terminals

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.

NOTE: 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.
