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 panels carefully.

ANCILLARY EQUIPMENT

Wharfedale speakers are compatible with the great majority of high fidelity equipment currently available - but a loudspeaker is only as good as the signal it gets. The quality of your source

with a soft damp cloth.

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).

Customising the PPS 1 Panels

The PPS 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, carefully follow the instructions below.

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 size of 360mm x 420mm.

First remove the existing print. Carefully lift one corner with a fingernail or wooden spatula and slowly peel off the print.

Lay a straight edge diagonally across the corners of the panel. Using a soft blunt 2B pencil or whiteboard marker gently mark four short lines as shown. 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 adhesive, lightly spray the back of the print as indicated. Allow to dry for 2-3 minutes.

Erase all the guide lines. Secure the picture frame back into place using the original eight screws removed earlier.

To aid picture mounting the frame may be removed. Carefully remove the eight screws in the moulded back cover and put safely to one side. Lift off the frame.

Place the print on the panel. When the corners touch all four lines, the print is centred. Mark the corner positions.

Apply the print and position it along the top edge only. Gently rub from side to side moving down the print whilst lowering it on to the panel. Smooth out any creases as you go.

Troubleshooting

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.

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.

Please read all the safety information before installing your PPS 1 Active System. It will help you install your system correctly. DO NOT connect loudspeaker terminals to the mains supply.

Ensure that all loudspeakers in the system are correctly wired and are in phase.

Site the LP 1 A 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 active 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.

If you have any doubts concerning your particular circumstance s your dealer will be happy to advise.

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 section 'Customising the PPS 1 Panels'

Mounting the 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 distances from the listening seat.

Each PPS 1 panel should be placed to the front or side of the listening position.

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.

used in conjunction with a computer, the headphone output on a portable audio unit, or to f a CD player or other Hi Fi uni that has a line output. The PPS 1A system can also be connected to a preamplifier output , or to a spare recording output of a regular Hi Fi system, to extend the sound to a remote location.

DO NOT connect the loudspeaker outputs of any unit to the audio inputs of the 2.1.

The subwoofer has three amplifiers, one for the sub bass unit and an amplifier for each NXT panel. The deep bass goes to the subwoofer and the rest of the audio signal to the panels.

Now mark a vertical centre line down to the floor.

Mark another short line on the wall at the position shown. This line is the upper level for fixing the cable to the wall.

Drill and fix a No. 8 screw and suitable wall plug. The screw should protrude about 5mm from the wall. Align the keyhole slots over the screws. Pull gently downwards to secure the panel. When both panels are correctly sited, lift them off and lay them to one side ready for connecting.

Connecting the PPS 1 Panels

The PPS 1 panel uses spring terminals located on the rear. Positive, Red(+) and Negative, Black(-) terminals are clearly identified.

The flat cables terminate in wire pigtails. Take each flat cable and connect it to a PPS 1 panel at the end you have prepared. Connect the pigtail with the Black sleeve to the Black terminal on the PPS1 panel. Press the lever at the side of the terminal and insert the cable. Release the lever and the wire is held firm. Now connect the pigtail with the Red Sleeve to the Red terminal.

Terminals should always grip the bare wire and no strands should ever touch adjacent terminals.

Hang each panel and cable assembly securely on the wall via the mounting slots. Hinge the panel slightly away from the wall and place the cable against the wall with the start of the exposed adhesive against the marked horizontal line. Ensure that the pigtail with the BLACK sleeve is to the RIGHT as viewed from the front.

Run the cable carefully down the wall, peeling off the backing tape and attaching the cable as you go. Keep the cable centered on the vertical line.

When the cable is 5mm above the floor covering, cut away the loose backing strip and run a cloth over the cable to press it firmly to the wall.

The flat cable is connected to the LP 1 sub bass unit via a length of speaker cable attached to the flat cable with a twin terminal block.

Partially unscrew the screws on the terminal block. Insert a bared end of each pigtail on the flat cable into each hole at one end of the block and screw them in place. Now screw in a prepared speaker cable at the other end. Make sure that the stripe or rib on the speaker cable connects to the BLACK pigtail.

The panels are now ready for connection to the sub bass unit.

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.

Connecting the PPS 1 System Panel Connections

Connect the speaker cable attached to the Left PPS 1 panel to the Left panel connection on the LP 1 sub bass unit. Connect the wire with the marker stripe to the Negative (-) Black terminal and the plain wire to the Positive (+) Red terminal. Repeat this procedure to connect the Right panel to the sub bass unit.

Note: The flat cable is supplied as an option. If you prefer you can connect the panels using the supplied speaker cable or a suitable a lternative.

connect to the panels.

Connecting the PPS 1 Panels

The PPS 1 panel uses spring terminals located on the rear. Positive, Red(+) and Negative, Black(-) terminals are clearly identified.

Terminals should always grip the bare wire and no strands should ever touch adjacent terminals.

Run the cable carefully down the wall, peeling off the backing tape and attaching the cable as you go. Keep the cable centered on the vertical line.

When the cable is 5mm above the floor covering, cut away the loose backing strip and run a cloth over the cable to press it firmly to the wall.

The flat cable is connected to the LP 1 sub bass unit via a length of speaker cable attached to the flat cable with a twin terminal block.

Partially unscrew the screws on the terminal block. Insert a bared end of

each pigtail on the flat cable into each hole at one end of the block and screw them in place. Now screw in a prepared speaker cable at the other end. Make sure that the stripe or rib on the speaker cable connects to the BLACK pigtail.

Customising the PPS 1 Panels

First remove the existing print. Carefully lift one corner with a fingernail or wooden spatula and slowly peel off the print.

To aid picture mounting the frame may be removed. Carefully remove the eight screws in the moulded back cover and put safely to one side. Lift off the frame.

Lay the print face down on some newspaper. Using a suitable spray mount adhesive, lightly spray the back of the print as indicated. Allow to dry for 2-3 minutes.

Apply the print and position it along the top edge only. Gently rub from side to side moving down the print whilst lowering it on to the panel. Smooth out any creases as you go.

Place the print on the panel. When the corners touch all four lines, the print is centred. Mark the corner positions.

Erase all the guide lines. Secure the picture frame back into place using the original eight screws removed earlier.

you will notice a sonic improvement, especially in the sub bass unit.

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

In 1932, when Gilbert Briggs founded the Wharfedale Wireless Works, his company was at the leading edge of an exciting new technology which was dedicated to bringing the pleasure of music and entertainment to a wide range of people. As the technology advanced Wharfedale gave many music lovers their first taste of High Fidelity, mounting a series of live sound demonstrations which excited the audio world and heralded the era of the modern hi-fi loudspeaker.

Today Wharfedale still takes the same uncompromising approach to the design and manufacture of every loudspeaker system, using high quality components and state-of-the-art testing to ensure consistently high performance. And that means that you can continue to count on the quality of all Wharfedale products.
