WHARFEDALE TRI-SURROUND (01) PDF Document

Switch off the amplifier and all sources before making connections to your sound system.

Set the volume control to minimum and turn up the level gradually.

Playing the system with extreme settings of volume and tone controls may damage the amplifier and loudspeakers.

Do not connect loudspeaker terminals to the mains supply.

Ensure that your loudspeakers are correctly wired and are in phase.

Do not subject your loudspeakers to excessive cold, heat or sunlight.

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 product.

No naked flame sources such as candles must be placed on the product. Do not place heavy objects on top of loudspeaker cabinets.

If you play them with the grilles removed be careful to protect the drive units from children and pets.

Do not use makeshift stands. Always fit a manufacturer approved stand using the instructions and the fixings provided.

Do not attempt to dismantle the loudspeaker. There are no user serviceable parts inside and you will invalidate the warranty.

Site your loudspeaker at least 0.5m away from TV sets and magnetic storage media.

Your Opus speakers are heavy. Take care when removing them from their packaging. Always take care when lifting heavy objects. Lift the speakers out by their sides. Be especially careful when removing the polythene bag.

The recommended steps for safely unpacking are:

1. Open the bottom.
2. Remove polystyrene.
3. Open bag containing speaker.
4. Tape the carton flaps back.
5. Turn over carton with loudspeaker still inside.
6. Lift carton off, leaving loudspeaker standing on the floor.
7. Be careful not to damage soft floor surfaces with spikes.

If possible, keep the packaging in case you need to move or return your speakers.

The accessories included in the User Pack for the WHARFEDALE TRI-SURROUND are:

• 2 Gloves
• Rubber Feet
• Bi-wire Links

Split the twin cores to a depth of about 40mm. Carefully strip the insulation from each end, leaving about 10mm of bare wire. If the cable is stranded, lightly twist to gather any loose strands.

Unscrew the terminal. Thread the bored end of each cable through the hole in the bottom of the terminal post. Ensure that there are no loose strands which may touch adjacent terminals. Retighten the terminal securely.

When connecting loudspeakers, the cables to left and right channels should be of equal length, regardless of the distance of the speakers from the amplifier. This applies to front and rear channels.

The front loudspeakers are placed on either side of the television screen, 2 to 3 metres apart. The speakers should be angled slightly so they are aimed towards the listeners. As the rear surround channels are the effects channels the reproduced sound should be as room filling as possible. We recommend placing the speakers in a high position, behind the listeners head. If the rear wall is more than 1 metre behind the listening seat, position the units on the side walls. If the walls are a long way from the listening seat, consider stand mounting the loudspeakers. Most of the dialogue comes from the centre loudspeaker. Speech should appear to originate from the actors mouths. Operating height is important. Ideally the front and centre channel speakers should be at the same height.

The speaker should ideally be sited 600mm – 1.5 metres above the listening position and 2.5 – 3.5 metres apart, central to the listener and behind the listening position, preferably on a rear wall. If the listening position is some distance from a rear wall, the loudspeakers may be mounted on opposite side walls but always behind the listening position.

Ensure that the wall is strong and can support the product. Drill two 5mm holes in the wall 160mm apart and horizontally aligned. Fix a suitable No 8 round head screw firmly into each hole using appropriate wall plugs. Leave a stub of 5mm protruding from the wall. Align the holes in the mounting brackets over the screw heads and carefully lower the unit onto the screws. The speaker can now be securely attached with the spacers resting against the wall. Now connect the speakers to the amplifier before final mounting of the surrounds.

In domestic systems the LFE channel typically feeds into the subwoofer. Where no subwoofer is used, the LFE signal is combined with front channel information and sent to the front speakers.

Immediately turn the AV Processor’s volume level down and then lower the LFE level. This should cure the problem. If it does not, lower the volume level at the subwoofer (if you are using one) until the problem disappears.

For Opus set the front speakers to ‘large’.

For Opus set the centre to ‘large’.

For Opus set the surrounds to small. The subwoofer then will reproduce only the LFE bass signals.

Set the subwoofer option on the processor to ‘Off’ or ‘No’. The front channels will now receive all the system bass.

When front speakers are set to small the bass for these channels will pass into the subwoofer.

If you choose large for the front channels, bass will be reproduced from the front speakers and the sub will just control the LFE channel.

Adjust the level of each channel in turn until all channels are reproduced at equal loudness.

Avoid setting too high a level or you will swamp the sound with bass. This can be tiring to listen to, and may limit the subwoofer’s ability to respond to large bass transients. You should also set a sensible level going into the subwoofer from the AV processor.

The purpose of delay is to enable surround and dialogue information to arrive at the listener’s ears at the same time as the front channels, even when the listening seat is in a non-ideal position.

A low delay setting should be set.

Set the delay to zero.

Increase the delay.

It is essential that the speakers are connected accordingly to the wiring diagrams in this manual, as if the colours on the loudspeaker terminals do not correspond with those on the amplifier, the sound will appear poorly focussed or ‘Out of phase’.

Consult your dealer for help.

Avoid getting any liquid behind the grille.

Remove marks from the cabinet and polish it with a soft, slightly damp cloth.

Do not open the speakers; there are no user serviceable parts inside.
