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
casepleasecheckthewiringtothepanelscarefully.
ANCILLARYEQUIPMENT
Wharfedale speakers are compatible with the great majority of
high fidelity equipment currently available - but a loudspeaker

CONNECTINGWIRES
Avoid trailing cables across open floor spaces where they can be
a source of danger. Route cables safely under carpets or along
roomboundaries.
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
immediatelyunderneaththeceiling(orcoving).

ThePPS 1 Panel can be customised with your choice of graphics.
For a small charge most high street picture specialists will be
happy to apply your image to the PPS 1. If you wish to do this
yourself,carefullyfollowtheinstructionsbelow.
The material on which the image is applied should be
lightweight-less than 300gsm. Canvas or painted surfaces are
not suitable, nor should the print be glazed. There must be
white space all round the print. We suggest a maximum picture
sizeof360mmx420mm.
First remove the existing
print.
Carefullylift one corner with a
fingernail or wooden spatula

Lay a straight edge
diagonally across the corners
of the panel. Using a soft
blunt 2B pencil or whiteboard
marker gently mark four

These marks can be removed
with a rubber after the print is
fixed.
Lay the print face down on
some newspaper. Using a
suitable spray mount

Mountingthe Panels
The PPS 1 panels are designed to wall mount. Conventional
loudspeakers need to be focussed on the listening position and
placed at an equal distance from the listener. Although this
conventional placement is still the preferred position, the
position of the panels is not critical, except that you should not
position the panels immediately next to each other. The panels
can be placed at different heights to each other and at different
distancesfromthelisteningseat.
Each PPS 1 panel should be placed to the front or side of the
listeningposition.
