Delay and LFE Settings
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.
If the listening position is equidistant from the Front and Rear speakers, a low delay setting should be
set.The closer the listener is to the Rear speakers the higher should be the delay setting used.
If the Centre speaker is level with (or slightly behind) the Front speakers, set the delay to zero. If the
Centre speaker is forward of the Front speakers, increase the delay.
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.When you set the LFE level at your AV processor, use care as the
powerful low frequencies can overload domestic loudspeakers. If you hear popping or thumping noises coming
from the front loudspeakers or subwoofer, immediately turn the AV Processor's volume level down and then back off
the LFE level.This should cure the problem. If it does not, back off the volume level at the subwoofer (if you are using
one) until the problem disappears.
Please read the relevant sections of your AV amplifier manual and familiarise yourself with the various issues. If you
are unsure, consult your dealer for help.
If your system is not working properly please work through this checklist before returning a unit to your dealer.
Before investigating a problem, always switch off the system at the mains.

Troubleshooting
No Sound:
The sound lacks bass content: Bass reproduction indistinct:
Excessive bass distortion at low volumes:
Excessive or distorted bass at high levels:
Distorted or rattling sounds at high levels:
Popping or thumping from the subwoofer:
Indistinct sound: Poor localisation of effects. Poor localisation of dialogue.
Television picture colour is distorted:
The system is not switched on. Speaker cables are shorting terminals out.The wrong source is selected.
The front loudspeakers are out of phase. The subwoofer is not switched on.
The subwoofer phase is incorrectly set. The subwoofer crossover control is set too low.
The subwoofer level is set too high.The LFE level is set too high.The subwoofer is incorrectly wired.
The system level is set too high. The bass control is set too high.The speakers are too close to room corners.
System level too high. Objects on speakers/subwoofer. Objects too close to subwoofer.
The system level is set too high. The subwoofer level is set too high.The LFE level is set too high.
One or more loudspeakers is out of phase. (Read the manual for correct connection procedure).
The subwoofer is too close to theTV. (Switch off the system andTV. Move the units apart. Switch on after 15 min.).

Why Bi-Wire?

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.
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.
All the 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.
Most speakers in the Diamond 10 series 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 pair
is connected to the bass terminal pair via removable metal straps. These should be
left in place for standard installations.
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.
The D10.0 compact monitor, the D10.CC compact
Centre Channel speaker and the D10.SR use similar
circular section two terminal crossover panels.
The D10.DFS uses a crossover network panel built
into the speaker’s rear wall.This is illustrated on
Page 7.
None of the above loudspeakers are bi-wireable.
