Unpacking
All Wharfedale products are fully tested and inspected before leaving the factory. After unpacking your loudspeaker please inspect it for any phys-
ical damage. In the unlikely event of damage caused in transit please contact your Wharfedale dealer immediately so that a written claim for
damages can be made. Please retain the shipping carton and all packing materials in case the unit needs to be returned.
Cables and connections
All Wharfedale Twin X loudspeakers are fitted with a pair of 4-pole Neutrik Speakon™ Connectors. The two connectors on each loudspeaker
are wired in parallel allowing two cabinets to be wired together from a single amplifier. When choosing speaker cable a professional grade of
cable with an overall round sheath will be harder wearing and easier to handle than hi-fi figure-of-eight cables. Cables should always be coiled
freely and not coiled over the hand and elbow which forces the conductors to twist within the outer sheath making the cable difficult to handle.
Speaker leads should be made with a minimum of 2.5mm? csa (12 gauge) cable. However for cable runs over 50m a minimum of 4mm? (10
gauge) cable should used.

Amplification & Power Handling
Wharfedale Pro loudspeakers should be driven by professional quality amplifiers capable of providing adequate headroom when operating at
high levels. A low powered amplifier with insufficient drive capability will not allow the full performance of the loudspeaker to be realised. A low
powered amplifier is also more likely to be driven into clip and damage to your loudspeakers.
Amplifier clipping commonly occurs when amplifiers are used that are too small for the loudspeakers. If these amplifiers are driven beyond their
maximum recommended limit the output from the amplifier is clipped. If a clipped signal is fed to a loudspeaker, it will not only detract from the
sound quality, but can cause permanent damage. [Clipped waveforms tend to heat up the speaker voice coil while driving it out of the magnetic
gap resulting in the loudspeaker overheating and failing]. Some amplifiers have a soft clip function which helps to round off the edges of clipped
waveforms. However, an external limiter, or crossover with limiting built in, will stop amplifier clipping and ensure long life from your enclosures.
[Note: Limiters must be adjusted to suit amplifier sensitivity. Refer to limiter or crossover manufacturer's literature.]
