Getting the Best From Your Loudspeakers
Phase
If the sound lacks definition or the bass is indistinct, the speakers could be
incorrectly wired (out of phase). If this is the case please check the wiring
to the loudspeakers carefully. This is particularly important if you have a
Home Theatre system.
Ancillary Equipment
Your Wharfedale speakers are compatible with the great majority of audio-
visual and high fidelity equipment currently available - but a loudspeaker is
only as good as the signal it gets. Your amplifier should have ample
reserves of power - a low powered amplifier could run out of steam quite
easily and the resulting distortion is unpleasant to listen to and could
damage your speakers. A larger amplifier will usually sound better and
enhance the reliability and performance of your loudspeakers.
Running In
Like all mechanical systems, loudspeakers to be 'run in'. For the first 50

Troubleshooting Guide

If your sound system appears not to be working as well as you expect, the
following notes may be of some help.
Before investigating the cause of a problem, always switch off the system
at the mains.
If you are using a Home Theatre system remember that such systems
can be quite complex and there is often a variety of factors involved.
Symptom
No sound at all
Sound lacks bass content
Bass reproduction muddy or indistinct
Excessive bass distortion at low volume levels
Excessive or distorted bass at high volume levels
Pops or thumps from the sub bass unit
Distorted or rattling sounds at high volume levels
Sound consists of just bass frequencies
No treble from one channel
Indistinct sound, poor localisation of effects
Television picture is distorted or there is colour
distortion

hours or so play your system at reasonable volume levels. After running in,
you will notice a sonic improvement, especially in the sub bass unit.
Connecting Wires
Avoid trailing cables across open floor spaces where they can be a source
of danger. Route cables safely under carpets or along room boundaries.
When mounting a panel on a wall the connecting cables may be
unacceptably obvious. Whilst the flat cable would normally be routed from
the panel to the floor, it may be less obtrusive to route cables from the panel
to the ceiling and then within or immediately underneath the ceiling (or
coving). The cable may then return to floor level at a convenient room corner.

Care and Maintenance

Very little maintenance is required. The Picture Panel frame and the
surface of the panel can be occasionally wiped clean with a soft damp (not
wet) cloth. Do not use detergents or solvents. Take care to use an
appropriate method if you have applied your own picture or painting.
Please read this manual together with all the manuals concerning the rest
of your system. If, having attempted to resolve the problem, the trouble
still persists, consult your dealer for assistance.
Do NOT try to remove any covers on the products or attempt to dismantle
them in any way. There are no user serviceable parts inside and you will
invalidate any warranty.
Possible Cause
Check that your hi-fi system is turned on and working ok.
Check all connections and cables. Ensure there are no short circuits across terminals.
Check that cables are not broken along their length.
Check the connections between the sub bass unit and the amplifier
Processor Subwoofer level set too high (where AV Processor is used)
Processor LFE level set too high (where AV Processor is used)
System level set too high, bass control set too high
Sub bass unit too close to room corners
Processor LFE or Subwoofer level set too high (where AV Processor is used)
System level set too high
Objects placed on sub bass unit
Objects too close to sub bass unit
Check connections and cables from sub bass to PPS 1 panels
The built in protection device on one or both PPS 1 panels has operated. Turn down the
volume control on your audio system until full output is resumed.
One or more loudspeakers is out of phase
(See the relevant pages of this manual for the correct connection procedure)
The LP 1 sub bass unit is too close to the TV. (Switch off the system and TV. Move the sub
bass away. Leave 20 mins. Switch on again)
