Wharfedale PPS 1 System User Guide
Introduction
The Wharfedale PPS 1 system is a unique sub
bass unit and satellite system based on
revolutionary NXT™ Surface Sound technology.
Now for the first time all listeners in the room can
enjoy spacious, detailed sound, not just the
favoured few directly on line with the speakers.
Please read the following information before
installing your PPS 1 System. It will help you
install your system safely and correctly.
Before making connections to any part of your
sound system make sure the amplifier and all
connected sources are switched off.
When you switch on your system or change
sources, set the volume control to minimum and
turn up the level gradually.
DO NOT use your amplifier at full volume.
The position of the Volume Control is NOT a
reliable guide as to the maximum volume level or
capabilities of your sound system. Playing the
system with extreme high settings of volume and
tone controls will result in distorted sound and
may damage the amplifier and loudspeakers.
DO NOT connect loudspeaker terminals to the
mains supply.
Ensure that all loudspeakers in the system are
correctly wired and are in phase.
DO NOT subject your loudspeakers to excessive
cold, heat, humidity or sunlight.
WARNING: To reduce the risk of fire or electrical
shock do not expose this product to rain or
moisture. The product must not be exposed to
dripping and splashing and no object filled with
liquids such as a vase of flowers should be
placed on the sub bass unit.
No naked flame sources - such as candles - must
be placed on the sub bass unit.
DO NOT place heavy objects on top of the sub
bass unit cabinet.
NEVER let anyone, push anything into holes,
slots or any other opening in the case.
Always fit the PPS 1 panels according to the
instructions and using appropriate fixings. Your
dealer will advise you if needed.
Do NOT connect the PPS 1 panels directly to the
loudspeaker outputs of a stereo power amplifier
or the front speaker outputs of an AV unit.
Connections to these outputs should only be via
the terminal panel on the LP 1 sub bass unit.
DO NOT attempt to dismantle the units. There
are no user serviceable parts inside and you will
invalidate the warranty.
Site the LP 1 sub bass unit at least 0.5m from
TV sets and magnetic storage media. The PPS1
panels may be safely used close to a TV set.
Unpacking
Unpack your system with care. Be careful not to
damage the panels and sub bass unit cabinet
when removing the polythene sleeves. Check
each speaker and in the event of any transit
damage, immediately contact your Wharfedale
dealer. Retain the packaging for future transit.

Compatibility
Your Wharfedale PPS 1 system has been
designed to be compatible with the great majority
of hi-fi and audio-visual equipment currently
available. If you have any doubts your dealer will
be happy to offer you advice.
The PPS1 panels employ a protection
mechanism that mutes the sound if the power
input is too great. If the output is muted, turn
down the main volume control on the system for
a few seconds to reset the level.
Your PPS 1 panels are supplied fitted with
lightweight decor pictures fixed to the panel
surface with low-tack adhesive. If you wish to
remove or change these pictures, please read
the paragraph 'Customising the PPS 1 Panels'
Mounting the Panels
The PPS 1 panels are designed to wall mount.
A conventional loudspeaker needs 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 distances from the listening seat.
Each PPS 1 panel should be placed to the front
or side of the listening position. Place the panels
behind the listening position only if you are using
them as the rear speakers in a surround system.
Fixing the Panels to the Wall
Three keyhole slots are located on the back of
each panel so that the panel may be wall
mounted in either portrait or landscape mode.
The PPS 1 is not supplied with screws or fixings.
Ensure correct selection of screws (they must
be round head, No 8) and fixings appropriate to
the structure and material they are to be applied
to. Seek qualified assistance if necessary.
The mounting screws must be securely fastened
into the wall or base structure. The entire
assembly should be capable of taking the weight
of the PPS 1 panels together with any pulling
force to which they might be subjected.
Positioning the Sub-Bass Unit
Although the LP 1 sub bass unit may be placed
almost anywhere in the room, even behind the
sofa or the TV set, we recommend that it be
placed in front of and as central to the listening
position as possible. The sub bass unit should
not be operated within 450mm of a television set
as the drive unit magnet may distort the picture.
We suggest you position the LP 1 sub bass unit
about 20cm (8 inches) from the wall. Placing it
close to the wall will enhance the bass; placing it
across the corner of the room will increase the
bass further, possibly at the expense of clarity.
The bass ports are essential to the functioning of
the sub bass unit and should not be obstructed
by placing the unit against soft furnishings. Do
not place the sub bass unit on an unsound floor
or close to surfaces or objects that may rattle.
