Preparing the D300 Loudspeakers
Stands and Brackets
The bookshelf loudspeakers are intended primarily for stand mounting, though they can be mounted on wall brackets or even on sturdy
shelves. The quality of loudspeaker stands greatly influences the performance of your loudspeakers, please do not use flimsy products.
Centre Channel Loudspeakers
Each of the Centre speakers is fixed with a set of rubber feet.The
port tube and rubber feet of the Centre speaker are all at the bottom,Non blocking
lead port tube when adjusting.It is especially useful that the smoothness of the port tube is directly affected by the sound effect of the centre channel.
Cables and Connectors
Choosing Loudspeaker Cable
Specialist audio cable usually offers better performance than general purpose 'bell' or 'zip' wire.
Choose a cable of suitable diameter - cable that is too thin will limit the dynamics of the sound and may impair the bass response. Audio cable
is polarised, with two cores of different colours, or often a raised rib or coloured tracer in the case of twin cable. Before you purchase your cable,
give careful thought to the positioning of your loudspeakers.
This is especially the case if you are bi-wiring your loudspeakers.
Cable lengths to loudspeaker pairs should be the same for left and right channels in order to equalise the signal
transmission. Allow some slack in your speaker cables so you can alter their position to best advantage.
Preparing Loudspeaker Cable
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.
Connecting Screw Terminals
All loudspeakers use screw terminals.
Unscrew the terminal. Insert the bare end of the cable into the hole in the base of the terminal. Tighten securely.
When connecting terminals make sure you leave no strands of bare wire that can short across to adjacent terminals.
As an alternative to bare wire you can use specialist spade connectors. Your Wharfedale dealer will be pleased to
advise you on this issue.
Crossover Networks
Bi-Wireable Networks
Most speakers in the D300 floorspeaker use a special bi-wireable crossover panel with four terminal
binding posts. Please follow the drawing carefully to see the correct orientation of the loudspeaker
terminals.The upper terminals connect to the treble unit, the lower pair to the bass unit. As supplied, the
treble terminal pairis connected to the bass terminal pair via removable metal straps.These should be left in
place for standard installations.
Why Bi-Wire?
Using separate cables for treble and bass units in a bi-wiring configuration reduces intermodulation effects
and improves headroom and clarity. To bi-wire, you will need to install two lengths of twin core cable
between the amplifier and each loudspeaker.
Standard Networks
The D310, D320 compact monitor, the D300C
compact centre Channel speaker D300SR compact surround channel speaker
None of the above loudspeakers are bi-wireable as smaller loudspeakers
derive no particular advantages from bi-wiring.
