Delay Settings
Many AV processors feature delay 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 listen-
ing seat is in a non-ideal position. On some processors, this can be achieved by setting the distance
from the listening position to each speaker in turn, but other systems allow only a time delay setting.

: 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 the
delay setting used should be.

: 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.
LFE
In the cinema the low frequency effects channel is an extra bass channel with its own subwoofer and
not a regular subwoofer channel. In domestic systems the LFE channel typically feeds into the sub-
woofer. Where no subwoofer is used, the LFE signal is combined with front channel information and sent
to the front speakers. When you set the LFE level at your AV processor, use care as the powerful low fre-
quencies 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 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.
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.
Phase
A home theatre system should have a precise front stage, a diffuse rear stage and good localisation of
dialogue. 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’. For this reason it is essential that the speakers are
connected accordingly to the wiring diagrams in this manual.
