Positioning/Initial Set Up
Leave the subwoofer unplugged from the mains until the installation procedure is
completed.
The subwoofer should 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 system configuration, room environment and personal tastes. However, for initial
trials set the controls as follows:
Volume Control Should be set to approximately 10 o’clock.
Frequency Control Should be set to the approximate frequency depending on
main speakers when using the L & R Line Level Inputs.
Bass Control Should be set to Movies when connecting to an AV receiver
or Music when connecting to a stereo amplifier.
Phase Control Should be set to zero degrees.
Mode Switch Should be set to ‘On’.
12v Trigger (optional) Do not connect at this stage.
Input Connections from the amplifier can be made at this stage
before the power is connected to the subwoofer. Refer to
items 1 and 2 on page 2.
Never connect or disconnect the RCA input/ output leads with the subwoofer 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 subwoofer can be connected to the mains power supply and switched on at the
mains power switch.
Do not play any music or movies at this stage as the auto set up of the AV amp (if using one) will need to
be run. If your amp has an auto set up procedure, run this now. If you do not have an auto set up or are
using a stereo amp connected to the left and right inputs, set the crossover in accordance with your main
speakers.
When the auto set up is complete, check that the subwoofer settings on the AV amp are correct. The level
should be no more/ less than +/- 3dB. If not we would suggest adjusting accordingly.
Now play a variety of familiar music/film excerpts and adjust the level of the subwoofer until you are happy
it integrates with the rest of the system. The volume of the amp can then be adjusted to an average
listening level. Once sure everything is working correctly, double check the subwoofer level settings.
NOTE: It might be necessary to adjust the speaker/ subwoofer settings manually if they are not to
your tastes or recommendations in the speaker/ subwoofer manuals.
