Owner's Manual
Setting
Loudspeaker
Sizes
and
Levels
If
you
are
not
using a subwoofer: Set
the
Front speakers
to
'Large'. Set
the
'Subwoofer'
option
on
the
processor
to
'Off'
or
'No
'.
The
Front
channels
will
now
receive
all
the
system bass.
If
you
are using a subwoofer:
When
set
to
'Small'
all
the
system bass
will
go
into
the
subwoofer
.
If
you
choose
'Large'
the
Front
channel
bass
will
be
reproduced
from
the
Front speakers.
Follow
the
instructions on this
page
for
suitable size
and
crossover settings.
Once
the
loudspeaker
settings
have
been
finalised,
put
the
A/V
amplifier
into
its 'Test'
mode
(see
instructions
supplied
with
your
processor}. Adjust
the
level
of
each
channel
until
all
channels are
reproduced
at
equal
loudness.
On
some
programme
material
the
surround
channel
may
s
eem
lower
in level than
the
front. Do
not
readjust this level. You may, however,
need
ta
adjust
the
subwoofer
output
level. 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
A/V
processor. Start
with
the
subwoofer
volume
control
set
to
between
12
o'clock
and
3
o'clock
.
Delay
and
LFE
Settings
Many
A/ V 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
listening
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,
but
other
systems
allow
only
a
time
delay
setting.
Rear Delay:
If
the
listening position is
equidistant
from
the
front
and
rear speakers,
set
a
low
delay
setting. The
closer
the
listener
is
to
the
rear speakers this
higher
the
delay
setting used
should
be
.
Centre Delay:
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
.
In
domestic
systems
the
LFE
channel
typically
feeds into
the
subwoofer
.
Where
no
subwoofer
is
used
,
the
LFE signal is
combined
with
the
front
channels
and
sent
to
the
front
speakers.
When
you
set
the
LFE
level
at
your
A/V
processor, use care as
powerful
low
frequencies can
overload
domestic
loudspeakers.
If
you
hear
popping
or
thumping
noises
coming
from
the
front
loudspeakers
or
subwoofer
,
immediately
turn
the
A/V
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.
Phase: Please read
the
relevant sections
of
your
A/V
amplifier
manual
and
familiarise
yourself
with
the
various issues. If
you
are unsure,
consult
your
dealer
for
help
. A
home
theatre
system
should
have a
precise
front
stage, a
diffuse
rear
stage
and
good
localization
of
dialogue
.
If
the
colours
on
the
loudspeaker
terminals
do
not
correspond
with
those
on
the
amplifier
,
the
sound
will
appear
poorly
focused
or
'
out
of
phase
'.
For this reason it is essential
that
the
speakers are
connected
according
to
the
wiring
diagrams
in
this manual.
Connecting loudspeakers
correctly
(in phase} is essential
whether
the
system
is stereo
or
multichannel. This is especially
important
if
you
are bi-wiring -
if
only
one
element
in a
bi-wired
system
is
incorrectly
connected
(out
of
phase},
the
effects can
be
very
noticeable
yet
hard
to pinpoint.
Troubleshooting
Before investigating a
problem,
always
switch
off
the
system
at
mains.
If
your
system
is
not
working
properly
please
work
through
this
checklist
before
returning
the
unit
to
your
dealer
.
