CONNECTING THE LOUDSPEAKERS
Bi-Wiring
Note: 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 heavy
bass current can modulate the high frequencies. Using separate cables for treble and bass units reduces intermodulation effects and
improves headroom and clarity. This technique of wiring is known as Bi-Wiring. To bi-wire, you will need to install two lengths of
twin core cable between the amplier 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 treble
units and the lower terminals feed the bass unit.
Connect the cables between the amplier 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 amplier the advantages of Bi-Wiring can be extended. If you own
two identical stereo power ampliers, you may wish to try bi-amping your QUAD loudspeakers. For further details please consult
your dealer.
GETTING THE BEST FROM YOUR LOUDSPEAKERS
Phase
If the sound lacks denition 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 Equipment
QUAD loudspeakers are compatible with the great majority of audio-visual and high delity equipment. Your amplier should have
ample reserves of power - a low powered amplier can run out of steam quite easily and the resulting distortion is unpleasant to
listen to and could damage your speakers. A larger amplier will usually sound better and enhance the reliability and performance of
your loudspeakers.
Running In
Loudspeakers are electro-mechanical and, like all mechanical systems, they need a 'running in' period. For the rst 50 hours or so
exercise care and play your system at reasonable volume levels. After running in, you will notice a signicant sonic improvement.
Care and Maintenance
Little maintenance is required. The cabinets can be occasionally wiped with a damp (not wet) cloth. Spray polish, if used, should be
applied sparingly - spray the polish onto a cloth and then apply it to the speaker. NEVER spray at the grille cloth or the speaker drive
units. To clean the grilles, remove them rst before gently brushing with a soft brush. Never use solvent cleaners, minor stains are
best removed with soap and lukewarm water.
Avoid touching the drive units as they can easily be damaged.
SERVICE & INFORMATION
Product service enquiries should instantly be referred to the supplying dealer. If you need to return your loudspeakers for servicing,
please return them as a pa ir even if only one unit appears to be faulty. For safety, we recommend that they be shipped in their
original packing.
