Positioning/Initial Set Up
Leave the AW-12 unplugged from the mains until the installation procedure is completed.
The AW-
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. The optimal control settings will depend entirely on
your system configuration. For initial trials set the controls as follows:
Volume Control
Should be set to minimum
Frequency Control
Should be set to the minimum position (40Hz)
Phase Control
Should be set to zero degrees
Power Mode Switch
Should be set to ‘Auto’ (if not using 12v trigger)
12v Trigger
Should be connected using the supplied (or similar) lead to the output
from your AV amplifier.
EQ Setting
This will be set as EQ1 by default when powered up
Low Pass Filter Switch
Should be set to the ‘Out’ position
Input connections can be made at this stage before the power is connected to the AW-12.
Never connect or disconnect the RCA input/ output lead connection with the AW-12 switched
on.
Set Up
Once the input cables are connected and the controls are set in accordance with the initial set-up procedure
above, the AW-12 can be connected to the mains power supply and switched on at the mains power switch. Do
not play any music at this stage. With the 12v trigger connected or Power Mode Switch in the ‘Auto’ position,
the unit should remain in standby (Power LED on the amp panel should be red, and the EQ1 button illuminated
blue) until the AV amp is turned on or a signal is received (when not using the 12v trigger).
Play a variety of music/ film excerpts that you are familiar with starting at a very low volume level, increasing
to an average listening level once you are sure everything is working correctly. Please now follow the bulleted
instructions below: -
• For use with an AV amp/receiver (product with Subwoofer output) please select the low pass filter switch to
the ‘Out’ position. Otherwise select low pass filter switch to the ‘On’ position. This engages the crossover
frequency control on the subwoofer (please refer to page 6).
• If using the crossover frequency control please adjust in accordance with the table on page 6. Further fine-
tuning may be required.
• Adjust the Volume Control to desired level for initial trials, ref. page 7
• The Phase Control can now be set, please refer to page 6 for further information.
It is important to try a variety of music and film excerpts with which you are familiar in order to obtain the optimum
overall settings.
