APC
uses
a
microphone
and
test
tones
to
automatically
calculate
detrimental
room
modes
and
automatically
correct
frequency
response,
optimizing
it
for
the
room

Spiked
Foot
Assembly
For
Carpeted
Floors
The Silver spiked foot assembly incorporates a spike for use on carpeted floors and also,
a soft polymer pad (for use on wooden or tiled floors).
~
Please ensure there are no hidden wires underthe carpetthat could be damaged
ill
by the spikes.
Locking
Nut
__
......,...,
MainThreaded _
__....,
Assembly
Spike
______
....,.
The foot comes fully assembled for use
on carpeted floors.
All
that
is
required
is
fixing into the bottom of the cabinet. This
is
achieved by simply screwing the feet fully
into the 4-threaded insert
in
the underside of
the cabinet.
If
your carpet has a very thick
pile, remove the soft polymer pad from the
foot
to
ensure the spike goes right through
the carpet into the floor. With great care turn
your cabinet the right way up. Place the
cabinet
in
your desired location, and check
that it
is
level on
all
sides. If it
is
slightly
uneven, unscrew the spike at the lowest
point and check again.
Continuethis process until the cabinet
is
fully
level. Use the locking nut on the foot to fix
the foot
in
place and to stop any unwanted
vibrations.
Spiked
Foot
Fixing
For
Wooden/Hard
Floors
For use on solid floors or where spikes are inappropriate, it
is
possible to use the foot without the spike.
To
use the foot
in
this
manner carefully grip the knurled portion of the spike and rotate anti
clockwise to unscrew the spike
fully.
You
may find it easier
to
first remove the polymer pad so
as
to
gain
more purchase on the spike.
The pad should be replaced beforecarrying outthe levelling operation
previously described.

The crossover frequency control only operates when connected to the stereo inputs.
It
does not have any effect when connected to the
LFE
input. This control feature
is
used
to
set the upper frequency limit (low pass) of the Silver W-12. The crossover
control should be set
in
accordance with the size or bass output of the main/satellite
speakers. Refer to the following chart as a guide
to
setting the crossover frequency
control to the optimum position. Much will depend on the correct low frequency
response
of
the main speakers and their position within the room. Experimentation
is
advisable.

ThePhaseControl
is
usedtosynchroniseanydelaybetweentheSilverW-12 and main/
satellite speakers. When the Silver W-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 set 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 0 degrees, especially when
using a digital
AV
processor or
AV
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
permanently 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
EO
button.
In
the 'Auto' position the subwoofer
will automatically wake once
an
input signal
is
received and will remain on while still
receiving a signal. The Silver W-12 will switch into standby mode following a period
of 20 minutes without
an
LFE
signal. Refer to page 9 for further information.

12Vdc
For external power control from
AV
amplifier/ receiver to the W-12. Monitor Audio
recommend using this function and a lead
is
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 energy efficient.
When using the 12v trigger, the Power Mode Switch
(3)
must be
in
the AUTO
position, for it
to
function correctly.

This input
is
to be used when 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

of filtering.
10.
Mains
Power
Switch
The Mains Power Switch should be switched to the 'Off' position when the Silver
W-12 will not be used for extended periods. 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 Silver W-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
external 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 fuse
from its holder below the
IEC
mains input socket
(11

Volume
Control
This
is
used to set the volume control of the sub-woofer. Adjust this
to
a level at
which the sub-woofer blends seamlessly into the rest
of
your system. See the Set
Up
proceedure on page 9 for recommended initial settings.
Initial
Set
Up
~
Leave the Silver W-12 unplugged from the mains until all signal cables
~
are connected.
The
W-12
should
now
be sited
in
the most suitable position, preferably not directly
in
the corner
of
a room as this may cause excessive bass boom. Once a desirable position
is
achieved it
is
important
to
check if the cables are long enough
to
reach comfortably
without being under tension. Cables should be less than 10 metres
to
avoid interference.
~
Never connect or disconnect the RCA input/ output leads with the Silver
~
W-12
switched on.
For initial setting up, put the Power Mode Switch
in
the 'On' position and leave the 12v
trigger cable disconnected.
Once the input (and output if necessary) cables are connected and the power mode
switch is
in
the On position, the W-12 can be connected
to
the mains power supply and
switched on at the mains power switch.
Power
Cycle
When the W-12 powers
up
for the first time or when it has been turned off for a long
period, the
EO
button will flash red 3 times while powering up and then
go
in
to
standby
mode
(if
power mode switch
is
in
the auto position).
When it senses a signal or
is
activated by the 12v trigger, the LED will illuminate white
while booting and then the colour of the previously sleceted (or default)
EO
profile.
If
the power mode switch
is
in
the On position it will be white while booting up and then
to
the colour
of
the previously selected (or default)
EO
profile.
To
continue with the set
up
procedure, put the power
mode
switch
in
the 'On' position
so that the APC can be initiated.

Set
Up
Automatic
Position
Correction
Automatic Position Correction
(APC)
will optimise the acoustic output of the subwoofer
to
match the ideal system performance by removing the dominant room modes from the
listening position. The APC will take measurements from 3 different seating locations
within the room to achieve the most accurate correction.
NOTE:
Please run the APC before running the automatic room set up ofyour
AV
amplifier.
To
perform APC, follow the steps listed below:
1.
Pressing the Calibration Button (item
2,
page
6)
while
in
normal operation will enter
calibration mode. A flashing blue
LED
in
the calibration button indicates that the
subwoofer
is
ready to perform
an
APC measurement.
2.
Place the microphone
in
the normal listening position, then press the
EO
button to
activate a room measurement. This will flash cyan and a series oftones will be heard.
If it doesn't get a good enough reading, the
EO
button
LED
will blink
red
and the
sub will run the test tones again until it gets
an
accurate enough measurement. The
LED
will then blink green, then purple (processing the equalisation) and
go
off. The
Calibration button will be flashing blue indicating that it needs to run a second and
third set of tones.
3.
Repeat step 2
in
another 2 listening positions
to
provide more room information for
the subwoofer.
Good locations for the 2nd and 3rd measurements would be 1m
to
the immediate
left and right ofthe initial listening position.
The subwoofer will then calculate the error between the current listening position and the
ideal frequency response ofthe system, then calculate and apply digital filters to optimise
the listening experience for the room.
When it has completed the APC the Calibration Button
LED
will go off, and the
EO
Button
LED
will go the colour ofthe previously selected
EO
profile.
If
you
do
not wish
to
run a second and third APC frequency sweep, you can cancel the
test by pressing the Calibration Button again.

Connected
to
an
AV
Receiver
The majority of
AV
amplifiers have automatic setup systems.
If
your amp has
an
auto set
up procedure, run this
now
with the volume set
to
around
10-
12 o'clock, and the power
mode switch
in
the On position.
When the auto·
set up
is
complete check the settings on the
AV
amp for the sub woofer
to ensure they are correct. The crossover frequency should be roughly the same as
in
the table on page 4 and the level should be no more/ less
than+/-
3dB. If not we would
suggest adjusting accordingly.
Now
play a variety
of
music/ film excerpts that you are familiar with gradually increasing
the volume to
an
average listening level once you are sure everything
is
working correctly.
Connected
to
a
Stereo
Amplifier
Stereo L
&
R input may be required if using a 2-channel stereo amplifier, or
an
amplifier
with no
LFE
output. Connect 2 x interconnect cables (left and right) from
an
amplifier
to
connections marked Inputs L &
R.
With the pre/ integrated amplifier set to a low level, set the subwoofer up using the
suggested guide below before playing any music/ test tones.
• Set the volume to around 10
o'clock
(Page
6)
• Frequency should be set
in
accordance to your main speakers (refer to the table on
Page
4)
• Phase
to
0 (Page
4)
Now
play some familiar music and gradually adjust the volume
and/
orthe frequency until
happy with the integration and balance
of
the sub woofer with the rest
of
the system.
