Positioning/Initial Set Up
Leave the subwoofer unplugged from the mains until the installation procedure
is completed.
The subwoofer 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, room environment
and personal tastes. However, for initial trials set the controls as follows:
Volume Control
Frequency Control
Bass Control
Phase Control
Mode Switch
12v Trigger (optional)
Input
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. If using the Radius Series speakers this should be around
80Hz, but experimentation is advisable.
When the auto set up is complete, check that the subwoofer settings on the AV amp are correct.
The crossover frequency should be roughly 80Hz 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 and adjust the level of the
subwoofer to a point where it integrates with the rest of the system and to where you are happy.
The volume of the amp can then be adjusted to an average listening level once you are sure
everything is working correctly to double check your sub woofer level settings.
