CONNECTING THE LOUDSPEAKERSBi-WiringNote: This provides an alternative to standard single-wire connections for improved overall soind quality.Most of the audio signal going to the speakers drives the bass units. Where one cable feeds both bass and treble units, this heavybass current can modulate the high frequencies. Using separate cables for treble and bass units reduces intermodulation effects andimproves headroom and clarity. This technique of wiring is known as Bi-Wiring. To bi-wire, you will need to install two lengths oftwin core cable between the amplifier and each loudspeaker.Unscrew each terminal a few turns and remove the metal straps. The upper pair of terminals on the crossover panel feeds the trebleunits and the lower terminals feed the bass unit.Connect the cables between the amplifier and the loudspeakers as indicated above and retighten all the terminals securely.Where feasible, we strongly advocate bi-wiring.Bi-Amplifying (Bi-Amping)By connecting each loudspeaker drive unit to its own dedicated amplifier the advantages of Bi-Wiring can be extended. If you owntwo identical stereo power amplifiers, you may wish to try bi-amping your QUAD loudspeakers. For further details please consultyour dealer.GETTING THE BEST FROM YOUR LOUDSPEAKERSPhaseIf the sound lacks definition or the bass is indistinct, this could be because you have inadvertently misconnected your loudspeakers.Please check the wiring to both loudspeakers carefully, especially if they are bi-wired.Ancillary EquipmentQUAD loudspeakers are compatible with the great majority of audio-visual and high fidelity equipment. Your amplifier should haveample reserves of power - a low powered amplifier can run out of steam quite easily and the resulting distortion is unpleasant tolisten to and could damage your speakers. A larger amplifier will usually sound better and enhance the reliability and performance ofyour loudspeakers.Running InLoudspeakers are electro-mechanical and, like all mechanical systems, they need a 'running in' period. For the first 50 hours or soexercise care and play your system at reasonable volume levels. After running in, you will notice a significant sonic improvement.Care and MaintenanceLittle maintenance is required. The cabinets can be occasionally wiped with a damp (not wet) cloth. Spray polish, if used, should beapplied sparingly - spray the polish onto a cloth and then apply it to the speaker. NEVER spray at the grille cloth or the speaker driveunits. To clean the grilles, remove them first before gently brushing with a soft brush. Never use solvent cleaners, minor stains arebest removed with soap and lukewarm water.Avoid touching the drive units as they can easily be damaged.SERVICE & INFORMATIONProduct service enquiries should instantly be referred to the supplying dealer.
