Crossover Frequency
Control
The crossover frequency control only operates when connectec
to the
stereo inputs.
It
does not have any
effect when connectec to the
LFE
input.
This
control
feature is used to
set the
upper
frequency
limit
(low
pass) of the Apex
AW-12. The
crossover control should
be
set
in
accordance with
the
size or
bass
output of
the
main/satellire speakers.
Refer
to the following chart as a
guide to
setting
the
crossover
frequency
control
to the ,iptimum position. Much
will
depend
on
the
correct low
frequency response
of the main speakers
ancl their position
within
the room.
Experimentation
is
advisable.
2.
Phase
Control
Switch
The Phase
Control is
usEd to
synchronise any
delay between the
Apex AW-12 and
main/satellite
speakers. When
the Ape< AW-12 is in phase
with
the main/satellite
speakers
the
sound should
be full
bodied.
Sit
in
a normal
listening position
whilst
adjusting the phase
switch.
Help from
another
person
may
be
required. When
,et
correctly
the location
of
the
subwoofer should
be
almost
undetectable.
Experimentation is
recommended
in order
to
achieve optimum
results. However it
should
be noted
that in most
cases
the phase
control switch should
be
set
to
O degrees, especially when
using
a
digital AV processor or
P.:,✓
receiver amplifier.
3.
Power Mode
Switch with
On-Auto Facility
The Power Mode Switch has
two positions:
'On'-'Auto'.
With
the
switch in
the
'On' position,
the
subwoofer
is permanentl,
switched on under all conditions and will
need to
be
manually
put into
Standby
mode. While in Standby
mode, the W-12
may be
woken
by pressing the EQ button. In the
'Auto'
position
the
subwoofer will automatically wake once an
input
signal
is received
and will
remain
on while still
recaiving a
~ignal.
The Apex AW-12
will switch into standby
mode following
a
period
of
20 minutes without an LFE signal.
Refer to page
8
for further
information.
4.
12 Volt Trigger Input
-
Centre Pin
=
+ 12Vdc
For
external
power
control
from
AV amplifier/
receiver to the
W-12.
Monitor
Audio recommend
using
this function and
a lead
i,;
supplied.
This 12
volt signal
is generated
by
the
AV amp/receiver
and tells
the W-12 to turn
on
from
standby
mode. This
allows a
more
accurately controlled
auto
on/off
function
,
and
is far more
anergy efficient.
When using the
12v trigger,
the
Power
Mode
Switch (3)
must be in
the
AUTO
position
,
for
it
to
function
correctly.
5.
USS Connector
This is provided
to
update the firmware
within
the
W-12.
6.
RCA Line Level Inputs
(Stereo
Left & Right)
For connection
to
a 2
ch:mnel/
stereo amplifier system. Connection should
be provided by
a pair of
high-quality signal cable,.
from the pre-out
section of an amplifier.
Note:-
cable
lengths
should not exceed
1
O metres
to
avoid
interference from other
electrical
appliances.
7.
RCA Line Level Outputs
(Stereo
Left & Right)
To be used
to fe<;id additional sub-woofers
to the
W-12
by
'daisy
chain'
type
connection
.
The
outputs
are
link
out only connections and do
not provide
any
form
of
filtering
.
8.
LFE Input (RCA Type)
This input is to
be
usec
wren connecting
the W-12
to an
AV
amplifier/
receiver.
When using the LFE input, the
crossover control is
not
used.
This
is
due to the
crossover
function being
controlled and set by
the AV
amplifier/ processor
when
it's
set
up procedure is run.
9.
LFE Output/ Link (RCA Type)
To
be
used
to fe<,d
additional sub-woofers tu t11e
W-12
by 'daisy
chain· type
connection.
The
output
is
a
link
out only connection
and does not provide any form of filtering.
10. Mains Power Switch
The Mains Power Switch
should
be
switched
to the
'Off'
position
when
the
Apex
AW-12
will
not be
used for
extended perioc,s.
The
switch
must be in the 'On
'
position for the
subwoofer
to function.
WARNING
:
Due
to the mains
switch being
located
on
the rear panel
,
the apparatus
must be located
in the
open area with
no
obstructions
to
access the mains switch.
11
.
IEC Mains Power Connector/ Fuse Location
The Apex AW-12
is supplied with a
two-pin mains input
socket for connection
to
the
mains
supply.
Use ONLY the
appropriate
IEC mains lead provided
with
the
product. Also
fitted
is an ex1ernal
mains
fuse. If a fuse blows
during operation a spare
fuse is
provided within
the fuse holder for replacement.
If you wish to
change
thE fuse,
you can
do this by removing the IEC mains lead
and carefully
levering
out the original fLJse from
its
holder
below the
IEC mains input
socket (11 a).
If the fuse
blows again
it
is advisable
to
Sf!ek
help from
an authorised service agent.
DO NOT
attempt
to re-fit
a
further fuse
as
this
could result
in
serious
damage to the
amplifier
unit.
12. Volume Control
This
control allows the level or volume
to be
adjusted
in
order to achieve a balanced overall sound.
To use this
facility you will
need to play
a selection of
familiar music
or
film
excerpts. Start with the
volume at
minimum
and
increase the level
control
until
a
balanced
sound is established.
If using
an AV
processor
or
AV receiver amplifier, the
system can adjusted
by the test tone function
within
the
set-up
features. (Refer to the
set
up
section in
the AV processor
or AV
receiver
amplifier
user
guide.) When
the
AW-12
is
correctly set-up, you should
not be
able
to identify its location
easily in the room.
13. EQ Button
This button has multiple functions, these
are: Wake
the
Subwoofer
from
standby with a single press;
When
operational,
it
cycles
through three
different
EQ
profiles.
14. EQ LED Indicator

EO Profiles
The
Subwoofer
has
3
preset EQ profiles. These
are
EQ1
(Movies},
EQ2"(Music)
and
EQ3
(Impact).
These profiles change the
characteristics of
the
sound
from the
subwoofer. We highly
recommend
experimenting with
the
different
profiles to
see which
most
suits your room, tastes, environment, etc. An
