Owner's Manual

1 . Crossover Frequency •:::ontrol
The crossover frecuency control only operates when connectec to the stereo inputs. It does not have any
effect when connected to t he LFE input. This control feature is used to set the upper frequency limit (low
pass) of the Apex AW-1 2. The crossover control should be set in accordance with the size or bass
output of the main/satelli.e 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 anc 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 li stening position whilst adjusting the phase switch. Help from another person
may be required. When se t correc11y the location of the subwoofer should be almost undetectable.
Experimentation is recorr mended 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 A' / 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 ·1 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 receiving a signal. The Apex AW-12 will switch into standby mode following a period of
20 minutes without an LF E 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 ii; 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.
5. USB Connector
This is provided to updat,~ the firmware within the W-12.
6. RCA Line Level Inputs (Stereo Left & Right)
For connection to a 2 channel/ stereo amplifier system. Connection should be provided by a pair of
high-quality signal cables from the pre-out section of an amplifier.
Note:- cable lengths she uld not exceed 1 O metres to avoid interference from other electrical
appliances.
7. RCA Line Level Outputs (Stereo Lett & Right)
To be used to feed additi.)nal sub-woofers to the W-12 by 'daisy chain' type connection. The outputs
are link out only connectbns 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 whe,1 it 's set up procedure is run.
9. LFE Output/ Link (RC!\ Type)
To be usecttoieed additi:inal sub-woofers to the 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 period 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. I EC Mains Power Connector/ Fuse Location
The Apex AW-12 is sup~lied 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 th6 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 a). If the fuse blows again it
is advisable to seek 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
This shows the selected EQ profile (while operational) and other states depending on mode and
colour.
WHITE Boot sequence
BLUE EQ Profile 1 (Movies)
PINK EQ Profile 2 (Music)
GREEN EQ Profile 3 (Impact)
RED Factory Reset (Static)
YELLOW & OTHER COLOUR - Fault mode (when flashing with other colour. See below.)
Further information on the EQ profiles can be found below.
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
example of the different profiles do can be seen below:
